Settled Privately, Sued Anyway: What the Law Says About the Paper You Signed

Three things people believe that the law does not say

A solicitor's letter arrives months after a roadside settlement and most people ask one question: is the paper any good? In law there are three separate questions in front of you, each governed by a different chapter, and the paper answers only one of them. Here are the three most common — and most expensive — beliefs.

Belief 1: "I signed a settlement, so it was full and final, and everything is over." What a settlement disposed of is decided by what the document itself says, not by what the parties later call it. The Court of Appeal did exactly that exercise in CACV 528/2021, [2023] HKCA 1277: one party argued that the plaintiff's settlement with an insurer had discharged the whole action and should be construed as a full and final settlement as between the plaintiff and all defendants. The Court did not accept either argument, because the terms of the consent order plainly covered the personal-injuries claim only, and there was no basis to read it as covering the entirety of the action. "Full and final" is not a label. It is a scope, and it is read word by word.

Belief 2: "Injury and vehicle damage are two different things, so paying for the car has nothing to do with his leg." In Hong Kong that has not been so since 2023. In the same case, the Court of Appeal held that where one tortious occurrence results in two types of damage it gives rise to one single cause of action, and expressly declined to follow the 1884 English decision in Brunsden v Humphrey (1884) 14 QBD 141. The change cuts both ways. You can no longer say the two are separate claims so the receipt cannot have touched the injury; and the other side cannot say they are one claim so the receipt must have. Both roads run back to the document.

Belief 3: "If enough time passes I am safe — limitation is the other side's problem." The opposite. Section 6(2)(b) of the Limitation Ordinance (Cap. 347) starts a two-year period running on the day you agreed how much to pay — and it is a period on your own right to make anybody else contribute, not a deadline on the claim against you.

⚠ But that clock has a precondition which matters just as much: section 6 measures the right given by section 3 of the Civil Liability (Contribution) Ordinance (Cap. 377), and s.3(1) is worded "in respect of the same damage". The two years is therefore keyed to the damage that was actually compromised. A settlement that dealt only with the cost of repairs disposed of the property-damage head; it does not, merely because bodily injury later emerges from the same collision, start a contribution clock on the injury head.

1. What a court actually reads in the paper you signed

The question is not whether a receipt for vehicle damage settles a personal-injury claim. It is what these two people objectively agreed — and that is read off the document and the background against which it was signed. The difference sounds like hair-splitting and it is not: it decides what the enquiry looks at, and what it looks at is the paper, not a legal principle.

The Court of Appeal worked through that exercise in 2023, in a road-accident case. In CACV 528/2021, [2023] HKCA 1277 the plaintiff settled with the motor insurer by consent order for HK$1,900,000, inclusive of interest and costs, and the consent order provided that the settlement was of the personal-injuries claim only. In his respondent's notice the 1st defendant argued that the settlement had satisfactorily and fully discharged the whole action so that the plaintiff was barred by res judicata, and that the court was not bound to accept that the settlement related to the personal-injuries claim alone but should construe it as a full and final settlement between the plaintiff and all defendants. The Court rejected both, and it is important to give both of its reasons rather than one. At paragraph 64 it held that *in light of the clear terms of the consent order and the repudiation of the insurance policy* there was no basis to construe the consent order — and in turn the settlement — as covering the entirety of the action. The two limbs are joined by "and". The second is not decoration: paragraph 63 explains that because the insurer had repudiated the policy, its liability under Cap. 272 was confined to any judgment on the personal-injuries claim, so a settlement made with that insurer could not have been reaching anything else.

There are several differences between that case and yours. First, the document was a consent order filed in court, made between a represented plaintiff and an insurer — not a sheet of paper signed by two drivers at the roadside. Second, the Court said in terms that it was not concerned with, and expressed no view on, whether the insurer had a valid reason to repudiate the policy. Third, the core issue in that appeal was the cause of action and jurisdiction, not the effect of a settlement; the scope point was decided in the course of disposing of the respondent's notice. And a fourth difference follows from the Court's own second reason: half of the ground it gave was the repudiation of an insurance policy, and at the roadside there is no insurer in the room and no policy to repudiate. That limb cannot travel to your piece of paper at all, which makes the case less transferable to it, not more. What does travel is this much: the scope of a settlement is read off its terms — and in that case the terms were not the whole of the reason.

A second framework comes from a Hong Kong judge who said these points had real force and then expressly left them undecided. In Dock Brian v Pacific Gourmet Holdings Ltd, HCLA 14/2021, [2022] HKCFI 444, an employment case, the document in question consisted in its entirety of one sentence confirming that the final payment of the employee's remuneration was correct and that nothing further was owing. The judge made three points: it was difficult to see any fresh consideration for the document; at first blush it seemed simply to confirm the calculations rather than to settle or waive some other claim, which was not mentioned and perhaps not even yet raised; and if it purported without consent to extinguish the employee's statutory rights it would be void. He then said those points might be subject to some degree of fact sensitivity in individual cases and were best left to be addressed on the facts by the Tribunal.

That framework has three limits. One, the ratio of that decision was jurisdictional, and the three points were expressly left undecided. Two, it was employment, not motor insurance. The provision the judge had in mind is s. 70 of the Employment Ordinance (Cap. 57), consolidation of 14 May 2026, and it is narrower than "an agreement": "Any term of a contract of employment which purports to extinguish or reduce any right, benefit or protection conferred upon the employee by this Ordinance shall be void." — a term of a contract of employment, which a roadside note between two drivers is not. Cap. 272 has no counterpart, as set out in section 6 below. Three, what transfers is general contract reasoning, not any case's conclusion. But that reasoning is exactly the shape of the problem: a document is not a compromise because somebody calls it one, and the court asks which claim it settled and whether that claim had even been mentioned.

A District Court case on this topic. Lo Wing Kwong v Wong Ka Wai Ruby, DCPI 1617/2006 (H H Judge Marlene Ng; heard 14 and 15 August 2007; judgment 18 December 2007). It is a District Court decision and it is not an appellate one.

The facts, from the judgment. The accident happened on 11 September 2003; the plaintiff was riding a motorcycle and the defendant was driving a private car (§1). On 29 September 2003 the defendant, having obtained the plaintiff's consent through the investigating officer to be given his mobile number, telephoned him and the two agreed a figure; the money was handed over in cash that afternoon at a carpark in Taipo, and each gave the other a written note (§§5, 47–49, 62, 64–66). At §5 the judge recorded the defendant's case:

The plaintiff brought his personal-injury claim in 2006, maintaining that the settlement had covered the motorcycle only (§6).

What the court held. At §60:

The plaintiff wrote and signed his own note; its operative sentence, set out at §66, was 「有關於 2003 年 9 月 11 日的交通意外不再追討任何責任。」 On its construction the judge said, at §67:

and at §68:

The disposal, at §85, is that the plaintiff

The limits of that case. One, the release was construed on its own wording against the facts the judge found about these two people. The approach the judge adopted, at §73, is that

and he concluded that the two notes

A release construed on its own wording in one case does not decide the next release. The words used, read in their factual context, are what decide it. Two, the plaintiff wanted to say the settlement was void for unilateral mistake, and the judge recorded (§8) that

So this is not a decision about the grounds on which a settlement can be set aside. Three, the judge made an alternative finding in case he was wrong (§86):

A gate that comes first: where the claimant is a minor or a mentally incapacitated person

⚠ Before any question about the document, note this provision: Order 80, rule 10 of the Rules of the District Court (Cap. 336H), consolidation of 28 March 2025:

Rule 1 of the same Order defines "person under disability" as "a person who is a minor or a mentally incapacitated person", and defines the latter by reference to the Mental Health Ordinance (Cap. 136). Rule 11 provides a separate route: where an agreement for the settlement of such a claim is reached before proceedings on the money claim are begun and the Court's approval to the settlement is desired, the claim may be made in proceedings begun by originating summons, and the summons may also apply for that approval.

Three points. One, rule 10 is worded "whenever entered into or made" — it does not on its face exclude a settlement made before any proceedings were begun. Two, what is quoted is the District Court rules; the Court of First Instance has rules of the same structure. Three, this is not the same "disability" as the one in section 3 below: Cap. 347 s.22 is about extending the limitation period on your own contribution right, while O.80 r.10 is about whether a settlement of the claimant's claim needs the Court's approval. They share a word and nothing else.

So what should someone holding a piece of paper actually be looking at? Taken together, the sources above point at three questions about the document, not about you.

• Which claim do the words of the document speak to? Does it say the money was for the car? Does it say it covers all claims arising out of the accident?
• Had personal injury been mentioned at all? The judge in Dock Brian specifically raised a claim that was not mentioned and perhaps not even yet raised.
• Was there any fresh consideration beyond what was already owed? If the money paid was the repair bill you already owed, that question gets asked. But the question has another side which cannot be left out: whether there was a disputed claim between the two of you at the time, and whether anything was given up on both sides. Money paid to end a disputed claim and money paid to clear an undisputed debt are not the same thing, and which of the two the roadside money was turns on the facts. ⚠ The judge who raised these three points expressly left them to be decided on the facts, and the provision he had in mind was s.70 of the Employment Ordinance. They are not settled principles.

All three turn on your own facts. But knowing that a court asks those three, rather than asking whether you signed, already changes what you take to a solicitor.

2. What the Court of Appeal changed in 2023: one accident, one cause of action

Until November 2023 no Hong Kong appellate decision had determined the point, and an 1884 English rule — that the injury and the vehicle damage from a single collision are two separate causes of action — stood unoverruled here. It does not stand now.

In CACV 528/2021, [2023] HKCA 1277 the Court of Appeal declined to follow Brunsden v Humphrey (1884) 14 QBD 141 and held that where one tortious occurrence results in two types of damage, it gives rise to one single cause of action.

The reasoning, at its shortest:

• A cause of action in the modern sense is a factual situation the existence of which entitles a person to obtain a remedy from the court — the definition given by Diplock LJ in Letang v Cooper, which the Court noted has been cited and consistently applied in that Court. On that footing, it is inapt to split a single factual situation into several legal situations.
• The Court found the reasoning of Porter JA, as endorsed by Hall J in Cahoon v Franks [1967] SCR 455, compelling: injury to the person and damage to the goods serve only as yardsticks for measuring the damage the negligent act caused.
• Brunsden also does not sit well with the rule in Henderson v Henderson, that a claimant is barred by cause of action estoppel from pursuing a claim which could have been litigated at the same time as a claim previously brought — a rule the Court noted has been regularly applied in our courts and affirmed at the highest level.
• The Court recorded how Brunsden had fared elsewhere: not followed in Canada (Cahoon), not part of the law of Scotland (Smith v Sabre Insurance Company Ltd [2013] SC 569), rejected in the United States, and doubted by the English Court of Appeal (Talbot v Berkshire County Council [1994] QB 290).
• And in Hong Kong, counsel informed the Court that Brunsden had been considered or mentioned in eight cases — none was binding on the Court of Appeal and none analysed whether the majority decision was correct, which is why the Court was free to decide the point afresh.

The case did not decide that settling one head releases the other. It did not concern a private settlement at all. And the appeal came up from a strike-out on a jurisdiction point.

So what changes for you? In one line: the automatic answer is gone, and it is gone in both directions. Before, a driver holding a repair receipt could say the injury was a different cause of action and the receipt could not possibly have touched it. That footing is gone in Hong Kong. But the reverse is equally unavailable to the other side: one cause of action does not mean the receipt must have covered the injury. A cause of action describes the shape of the claim, not the scope of a release. The scope of a release goes back to the three questions in section 1.

The doctrines in play: Where a single accident gives one cause of action, the questions that arise about a settlement of it are the ordinary questions of accord and satisfaction — whether what was agreed and what was actually given amount to a discharge of the claim — and of merger. The 2023 case decided nothing about accord and satisfaction or merger. In Lo Wing Kwong, DCPI 1617/2006 (section 1 above), counsel for the plaintiff relied on Lord Denning MR's accord-and-satisfaction passage in Arrale v Costain Civil Engineering Ltd and asked the court to construe the two notes on the parties' subjective intent. The judge declined that approach and added, at §73, that

So the accurate statement is this: accord and satisfaction has been argued before a Hong Kong court in a private settlement of a traffic accident, and that court disposed of the case by objective construction rather than by any holding on accord and satisfaction.

3. The clock that is easily missed: two years on the same damage, from the day you agreed the amount, and it is yours

The day you agreed the amount closed nothing. It may have started something — and what it starts is running against your own remedy, not against the claim being made on you. ⚠ Note that the section turns on agreement, not payment: s.6(2)(b) fixes the date as the earliest date on which the amount to be paid is agreed, not the day the money changes hands. Those can be months apart. ⚠ And note which damage: section 6 measures the right conferred by Cap. 377 s.3, and that section is worded "in respect of the same damage", so the two years is keyed to the damage that was compromised and does not travel of its own accord to a different head of damage from the same accident.

Section 6(1) of the Limitation Ordinance (Cap. 347):

Two years. The next question is: two years from when. Section 6(2) answers in two paragraphs, and (b) applies by its own words only "in any case not falling within paragraph (a)" — so paragraph (a) comes first:

So where you are held liable for that damage by a judgment or an arbitration award, the date is the date of the judgment or award and no agreement date is in issue. The two paragraphs have to be kept apart; they cannot be compressed into "it runs from the day you agreed". A roadside settlement will not usually fall within (a), which is how paragraph (b) is reached:

In plain terms: the period runs from the earliest date on which you and the other side agreed how much you would pay — and the subsection says in terms that it makes no difference whether you admitted liability. If what you said at the roadside was that you were not admitting anything and simply wanted the matter closed, the subsection has already anticipated that sentence and has already said it does not stop the date from counting. The closing words mean that if the amount is later varied on appeal, the variation does not reset your date.

And what is the two years a period on? A right that belongs to you — and the Ordinance puts a boundary round that right. Section 3(1) of the Civil Liability (Contribution) Ordinance (Cap. 377):

"In respect of the same damage" is the gate on the whole route. Contribution is not "I paid something, so somebody else should share it"; it is "you and I are both liable for the same damage". The two years in Cap. 347 s.6(1) runs from the accrual of that right, so where no such right has arisen there is no clock. What that means for the reader: a settlement that dealt only with repairs is directed at the property-damage head. Whether there is a contribution right of yours in respect of the personal-injury head, and when it accrued, is a separate question, and it is not answered merely because both heads came out of one collision. Subsection 3(4) then deals with the settlement case:

In other words, a person who has settled in good faith may seek contribution from others liable for the same damage — a second driver, a vehicle owner, an employer — without regard to whether he himself was ever liable. But the closing words of the subsection are a condition: he must be someone who would have been liable assuming the factual basis of the claim against him could be established. A person who could never have been liable at all does not acquire the right by paying.

Four limits

First, an overpayment does not count. Section 3(5) of the same Ordinance:

Paying more at the roadside than the matter was worth, to make it go away, does not make the contribution you can later recover any larger.

Second, how much is recoverable is set by the court on responsibility, and it is capped. Section 4(1) provides that the amount recoverable from any person is such as may be found by the court to be just and equitable having regard to the extent of that person's responsibility for the damage. Section 4(3) then caps it: where the damages that would have been awarded against that person would have been subject to a limit or to a reduction — and the subsection expressly names a reduction by virtue of section 21 of the Law Amendment and Reform (Consolidation) Ordinance (Cap. 23), that is, a reduction for contributory negligence — the contribution cannot exceed the damages as so limited or reduced.

Third, the other person's own limitation position is not necessarily their answer. Section 3(3):

The subsection distinguishes between a limitation period that merely bars a remedy and one that extinguishes the right itself. The practical consequence for you is short: the clock to watch is your own two years, not theirs.

But "contribution" is a defined route, and it is not the only one — which matters, because the two years is keyed to it. Section 6(1) of Cap. 347 fixes its two years by reference to section 3 of the Civil Liability (Contribution) Ordinance, and section 9(3) of that Ordinance says in terms what it leaves alone:

So a right to be indemnified — one that comes from a contract, express or implied, or from somewhere other than Cap. 377 — is expressly saved, and the two-year period keyed to section 3 does not reach it. Whether you have such a right at all is a question about your own documents. "Your own two years" is the clock on a contribution claim, not on every route by which a bill might be passed on.

Fourth, the two years does not always run from the day the amount was agreed. Section 6(1) opens with the words "subject to sections 22 and 26". Section 22 deals with disability, and it has a subsection written for this very right. Section 22(1) extends a period by six years from the day the disability ends. But subsection (2A) substitutes a shorter figure wherever section 22 is reaching a contribution claim:

Two years, not six. The extension that a disability buys on a contribution claim is the same length as the ordinary period, not three times it — and the contribution right is the one section 22(2A) is talking about. Section 26 deals with fraud, concealment and mistake:

And subsection (3) of the same section widens what counts as deliberate concealment:

Those two subsections make the two years accurate rather than making it soft: two years is the rule, and the Ordinance itself names when the period does not start on the day of the agreement.

And in the same Ordinance, two provisions about releasing one person — read as a pair

Section 7 — releasing one person does not release another:

Section 5 — a judgment against one is not a bar to an action against another:

Section 6 sits between them, and it attaches a price to the very thing sections 5 and 7 leave open:

Read together the three are one architecture: in an accident involving more than one vehicle, or an employer, settling with one person does not of itself discharge the others — unless the release says so — but bringing your claims in separate actions can cost you the costs of all but the first, unless the court thinks there was reasonable ground for the later one. And the point runs the other way too: the other side settling with a second driver does not of itself discharge you.

The limitation periods at a glance

The detail of the three-year row — how the date of knowledge is defined, the court's power under section 30, the extension for disability — is in our traffic-accident claims guide.

4. Insurance: the statute protects the injured person, at your expense

Cap. 272 was written from end to end to make sure an injured person is paid. Every consequence for you follows from that one choice — including the last one, which is the insurer's right to recover the statutory excess.

First: what you did after the accident cannot be used to defeat the third party's claim

Section 9:

A clause requiring notification within a stated number of days on pain of losing cover, or a clause forbidding an admission of liability, is precisely a condition about "some specified thing being done or omitted to be done after the happening of the event". The section says such a condition is of no effect in connection with the claims mentioned in section 6(1)(b) — the compulsory third-party death-or-bodily-injury cover.

But the proviso in the same section cannot be left out, because it is where a policy's own repayment term survives:

Section 9 does not make void a clause requiring you to repay the insurer. The protection runs to the third party. The obligation to repay can stay with you.

Second: the insurer must satisfy the judgment even on a policy it could avoid

Section 10(1):

That is the backbone of the system. Subsection (5) of the same section:

Without subsection (5), section 10(1) would eat itself: it requires a "liability covered by the terms of the policy", and a policy that has been avoided appears on its face to cover nothing. Subsection (5) brings in a liability that would be covered but for the insurer's entitlement to avoid or cancel, and only then does section 10(1) bite on an avoided policy.

And a Hong Kong court has applied section 10(1). In CACV 528/2021, [2023] HKCA 1277 the 3rd defendant insurer had repudiated the policy on the ground of false declaration or material non-disclosure — the 1st defendant had been disqualified from holding a driving licence at the time the insurance proposal form was made. The Court recorded that despite the repudiation, the insurer was under a statutory duty to satisfy any judgment in favour of the plaintiff on the personal-injuries claim, including interest and costs, by reason of section 10(1) read together with section 6(1)(b) of Cap. 272.

Two limits. First, the Court said in terms that it was not concerned with, and expressed no view on, whether the insurer had a valid reason to repudiate. Second, because the policy had been repudiated, the insurer's liability under Cap. 272 was confined to a judgment on the personal-injuries claim — it did not extend to the claim for damage to the vehicle.

Third: section 10(1) is not a guarantee, and it says so in its own words

Section 10(1) is expressed to operate "subject to the provisions of this section", and the rest of the section is five separate ways out:

• Section 10(2)(a) — seven days. "(a) in respect of any judgment, unless before or within 7 days after the commencement of the proceedings in which the judgement was given, the insurer had notice of the bringing of the proceedings; or" Note where the seven days runs from: the commencement of the proceedings, not the accident.
• Section 10(2)(b) — nothing is payable so long as execution on the judgment is stayed pending an appeal.
• Section 10(2)(c) — where the policy was cancelled by mutual consent or under its own terms before the event, and the certificate was surrendered before the event, or within 14 days of the cancellation taking effect, or a statutory declaration of loss or destruction was made, or the insurer commenced proceedings within that 14-day period over the failure to surrender it.
• Section 10(2)(d) — the cap. Nothing is payable in respect of any sum adjudged payable in excess of the amount covered by the policy after deducting anything the insurer has already paid or owes under the policy for the same event. This is where your own exposure begins: the statute guarantees what is inside the policy, and nobody stands behind the part that is outside it.
• Section 10(3) — the declaration route. An insurer that commences an action before, or within 3 months after, the commencement of the proceedings and obtains a declaration that it is entitled to avoid the policy for non-disclosure of a material fact or for a materially false representation of fact is not liable to pay; the proviso to that subsection carries its own seven-day notice requirement to the plaintiff. That door was closed in England in 2019 and is still open in Hong Kong — see section 5.

Fourth: how the statutory excess gets back to you

Section 10(4):

And section 10(4) is not the only provision in Cap. 272 that can put money back on the driver. ⚠ What s.10(4) gives the insurer is a right to recover "the excess" — the amount it becomes liable to pay under the section above what it would have owed under the policy — not the whole third-party payment, and not an automatic debt on every breach. Section 12(1) strikes out certain restrictions in a policy — on the driver's age, the vehicle's condition, the hours or areas of use — so that the insurer must meet the third party's claim anyway. Its proviso then does the same thing section 10(4) does:

Two statutory routes, then, not one: where the insurer pays because section 10 or section 12 overrode something in the policy, the Ordinance lets it come back to the person insured for that money. Section 12(1) is about restrictions written into the policy at inception.

The insurer's right to recover the excess comes from the statute itself, not only from the policy.

The motor insurance industry describes the same architecture. The Motor Insurers' Bureau of Hong Kong, in its notes for guidance on claiming compensation, is careful to say that the scheme leaves a policy's own terms exactly where it found them. Being covered by the scheme does not discharge a driver from whatever the contract with the insurer requires; the protection runs to the injured third party, not to the driver, and it does not clean the driver's side of the bargain. The Bureau's worked example: where the contract called for a claim to be reported and the driver did not report it, the victim is still paid out under the scheme, and the driver can still be answerable to the insurer for the omission. (This site's summary.)

Fifth: no statute requires you to tell your insurer anything — and that is the point

Cap. 272 contains no duty to tell your own insurer about an accident, and no provision about a settlement or an admission of liability; both language texts are the same. And the Road Traffic Ordinance (Cap. 374) does not deal with insurers at all.

One sentence: neither Cap. 272 nor Cap. 374 imposes a duty not to admit liability or a duty to notify your own insurer. Where those duties live is the contract — a document only you hold.

Motor policy wordings differ; check your own policy.

The following may help:

• The industry's own code. The claims part of the Hong Kong Federation of Insurers' code of conduct for insurers sets two standards relevant here. On timing, it tells an insurer not to fix reporting deadlines that are arbitrary or unreasonable, and says the contract should ask no more than that the insured report the claim, and what happens after it, without undue delay — unless the insurer has a sound reason for naming a fixed date or a fixed window. On consequence, it says that where the insured has not been fraudulent, a broken warranty or condition ought not by itself to sink a claim when the loss owes nothing to the breach. (This site's summary.) But it is an industry self-regulatory code, not law, and it is not your policy.
• The regulator's position, on the record. In a written reply of 25 February 2026 the Government said:

> "Generally speaking, the reporting requirement stipulated in insurance policies should be “reasonable and practicable”. Where a policyholder is, on an objective and reasonable basis, unaware of an accident or claim, insurers should, under the premise of adhering to the policies and procedures, consider the specific circumstances in handling the case. Therefore, IA encourages policyholders to report all known traffic-related accidents to their insurers as soon as practicable, including vehicle theft and damage, bodily injury or third-party property damage, to safeguard their policy interests."

That is materially softer than "report late and you lose your cover", and its character matters as much as its content: it is what the regulator expects of insurers, not a rule of law, and not a statement about any particular policy. The next paragraph of the same reply adds:

> "Moreover, HKFI reminds policyholders to immediately report to their insurer upon receiving a summons for a traffic offence or a notice of a case reported to the Police even if the policyholders believe they are not at fault or the damage appears minor. This allows experienced professionals to manage any subsequent civil claims. Policyholders with questions about claims and reporting arrangements under their insurance policies are advised to consult their insurers."

A solicitor's letter is not among the triggers it names.

• A range that practitioners report. A Hong Kong law firm states that the reporting deadline depends on the insurance company's terms and is generally within 24 to 72 hours of the accident, with a full written report usually to be submitted within 14 days. It is a range, and its source is the policy terms, not legislation.

5. England closed a door in 2019. Hong Kong did not.

Cap. 272 is a transplant of the English compulsory motor insurance architecture of the 1930s, and the Ordinance says so on its own face: section 9 is marked "[cf. 1930 c. 43 s. 38 U.K.]" and section 13 "[cf. 1934 c. 50 s. 13 U.K.]". Once you know it is a transplant, the useful question is whether the parent still reads the same way. On two points it does; on one it does not, and that one runs against you.

[England, Wales and Scotland] The seven days is still the live rule. Section 152(1)(a) of the Road Traffic Act 1988 carries the same rule as Cap. 272 s.10(2)(a): England spells the number in words where Hong Kong writes it in digits, and the fourteen-day certificate-surrender limb is common to both.

The real divergence is not the seven days. The textual amendments recorded against section 152 of the Road Traffic Act 1988 show that S.I. 2019/1047 substituted words in s.152(2) and omitted ss.152(3) and (4) with effect from 1 November 2019.

• [England, Wales and Scotland, since 1 November 2019] a motor insurer that wants to escape paying the third party's judgment on non-disclosure or misrepresentation must have obtained its declaration before the event that caused the death, bodily injury or damage. After the accident it is too late, and the notice machinery that used to accompany the old route went with it.
• [Hong Kong, on the consolidation of 24 August 2025] Cap. 272 s.10(3) is still there: the insurer may commence its own action before, or within three months after, the commencement of the proceedings and obtain the declaration, with a seven-day notice proviso of its own.

Section 10(1) is not a guarantee. In England, since 1 November 2019, the route of obtaining that declaration after the event has been closed; in Hong Kong s.10(3) is still open.

A third divergence, in the same direction. [England] the duty to report under s.170(3) of the Road Traffic Act 1988 arises where the driver did not give his name and address and the other particulars that s.170(2) requires. ⚠ Name and address alone are not the whole of what displaces the duty. [Hong Kong] s.56(3) of Cap. 374 is conditional on nothing: if the accident involves injury to any person including the driver, it must be reported.

Another contrast. The Road Traffic Act 1988 contains no rule about a settlement, a compromise, admitting liability or any cooling-off period; its only reference to an "admission of liability" is in section 157. So the point made in section 4 — that the duty not to admit and the duty to notify are contractual rather than statutory — is not a quirk of Hong Kong drafting. Both systems are silent in the same way.

And England did legislate about settling a motor injury claim — but it reached the professionals, not the parties. [England and Wales] section 6 of the Civil Liability Act 2018, in force 31 May 2021, prohibits inviting a person to offer, offering, making or accepting a payment in settlement of a whiplash claim before appropriate medical evidence has been obtained. But the regulated persons listed in s.9(1) are FCA-authorised persons, claims-management providers, and persons authorised by the Bar Council, the Law Society, CILEX or an ABS licensing authority — two drivers at the roadside are on none of those lines. And s.7(6) provides that a breach of section 6 does not make an agreement to settle the whiplash claim void or unenforceable. The rule is confined to soft-tissue injury of the neck, back or shoulder, on a road or other public place in England or Wales, with motorcycles expressly excluded.

One last comparison. [UK] In Hayward v Zurich Insurance Company plc [2016] UKSC 48 a settlement was indeed unravelled — and the party that unravelled it was the insurer, against a claimant who had exaggerated. The same judgment expressly left a point open at paragraph 73: whether a party seeking to set aside a settlement for fraud must prove the fraud by evidence it could not have obtained by due diligence at the time of the settlement was conceded for the purposes of that appeal, the court heard no argument on it, and the court said it was better to say nothing about it. That is English law, not Hong Kong law. The District Court case on this topic — Lo Wing Kwong v Wong Ka Wai Ruby, DCPI 1617/2006, judgment of 18 December 2007 — does not decide them. The plaintiff there wanted to say the settlement was void for unilateral mistake; the judge recorded at §8 that the point had not been pleaded and was therefore not open to him, adding that unilateral mistake as to the terms of a settlement could in any event only be set up if the mistake were known to the other party, and that there was no such evidential basis in that case. What that gives is one unpleaded attempt that failed, not a set of grounds.

6. Three times the legislature reached for the tool that voids an agreement — and aimed it elsewhere each time

Where a Hong Kong statute voids a settlement, the injured party is protected by law. Where none does — and motor third-party insurance is that case — nothing in the Ordinance stands between the agreement and the ordinary law of contract.

In the Employees' Compensation Ordinance (Cap. 282), the one provision that expressly makes an agreement void is section 31, and section 31 has to be given with its own two qualifiers rather than flatly: the contract is void "subject to subsection (2)", and only "in so far as it purports to remove or reduce the liability of any person to pay compensation under the provisions of this Ordinance" — while subsections (2) and (3) allow the Commissioner, on the ground of old age or serious physical defect or infirmity, to authorise exactly such an agreement, which is ineffective unless he certifies it fair and reasonable.

The Motor Vehicles Insurance (Third Party Risks) Ordinance (Cap. 272), by contrast, contains no provision at all making an agreement void or permitting a claim to be relinquished. Its single true use of "void" is in the proviso to section 9, where it does the opposite of striking a clause down — it preserves a policy term requiring the insured to repay the insurer. "Of no effect" appears in sections 6, 7, 9 and 12.

Every "of no effect" provision and the one "void" are aimed at a policy or a security — a condition in one, a restriction in one, an antecedent agreement with a passenger, a repayment term preserved — and not one of them is aimed at the agreement between the two drivers. (Employees' compensation is a separate regime; it appears here only as a contrast.)

The legislature has once voided a private agreement between a driver and a person who might be injured — and aimed it at a different situation. Cap. 272 s.12(2):

"whether intended to be legally binding or not" — a formula wide enough to catch an understanding that was never meant to bind at all. But subsection (3) of the same section closes it down:

"one made at any time before the liability arose" A settlement struck at the roadside after a collision is not an antecedent agreement, so s.12(2) does not touch it and cannot be used to say a roadside settlement is void. What reaches a post-accident policy condition is section 9, not section 12(2).

The same tool, a fourth time: a law reform recommendation that was made and never enacted. In 1982 the Attorney General and the Chief Justice put a question to the Law Reform Commission. As the law then stood, an insurer could escape liability on the policy in two situations: where the insured had, when the policy was taken out, kept back or misstated something material; and where the insured had broken one of the policy's conditions — and in that second case it made no difference whether the thing kept back, misstated or broken had anything whatever to do with how the accident happened or with the claim being made. Should that be changed, and if so how? (This site's summary.)

The second limb of that reference is exactly the roadside-settlement driver's position. A driver who settled at the roadside and did not tell the insurer has breached a condition that has nothing to do with how the accident happened.

The Commission's answer, at paragraph 3.22 of its report of January 1986, drew on the New South Wales Insurance Act 1902. Where a warranty is broken and the loss follows from the breach, the Commission accepted that an insurer may fairly decline to indemnify. Where the loss does not follow from the breach, it thought the court should be able to look at the case as a whole. So it proposed that in any court proceedings on a dispute under an insurance contract, the judge should have power to set aside the insured's non-observance of a term or condition — where that is just and equitable on all the circumstances, and where the insurer's position has not in fact been damaged by it. (This site's summary.)

It never became law. No Hong Kong chapter carries the rule that was proposed; and Cap. 41 itself, on the consolidation of 23 May 2025, never speaks of non-disclosure, never speaks of a warranty, and carries nothing about an insurer avoiding a policy.

And on settlement itself, the law reform record points toward finality rather than away from it. The Commission's report of January 2023 describes how money damages are awarded here: in one sum, not by instalments. What the claimant has already lost and what the claimant will lose in future are valued together and fixed, finally and for good, as a single figure — and the moment at which that figure is fixed is the hearing or the agreement. The same report's first final recommendation asks that legislation give the court power to order periodical payments for future money loss; it then adds, for the avoidance of doubt, that the new power is meant to take nothing away from an adult of sound mind who chooses to settle amicably with the wrongdoer or with whoever is paying. (This site's summary.) The limit in the second passage is stated of a person who is not mentally incapacitated: where the claim is made by or on behalf of a person under disability, Cap. 336H, O.80 rr.10–11 require the Court's approval of the settlement — see section 1.

So the conclusion of this section is not that nobody thought of it. In employees' compensation the legislature voided contracting out. In employment it voided contracting out. In motor third-party insurance it voided policy conditions, policy restrictions and an antecedent agreement with a passenger — and about the agreement between the two people in the collision it said nothing at all.

7. The criminal side is a separate question from what the two of you agreed

The three duties in Cap. 374 s.56 are covered in our traffic-accident claims guide, our crash-scene checklist and our crash-for-cash guide.

First, the Road Traffic Ordinance contains no provision prohibiting a private settlement.

Second, both reporting limbs carry both tests. It is not that one limb has only a 24-hour test and the other only a reasonable-practicability test.

Two asymmetries, both on the face of the section.

• Asymmetry one: exchanging details switches off one duty and does nothing to the other. Section 56(2A) arises only where both conditions hold: the accident is one referred to in s.56(1)(b) — the damage limb — and the driver did not give the s.56(2) particulars. Give the particulars and the (2A) duty never arises. Section 56(3) is different: it arises wherever the accident involves injury to any person including the driver, whether or not particulars were given, and it carries its own excuse in its closing words — unless the driver is incapable of doing so by reason of injuries sustained in the accident.
• Asymmetry two: the duty to stop and the duty to report cover different people. The gate at s.56(1)(a) reads "(a) personal injury is caused to a person other than the driver of that vehicle; or" — expressly excluding the driver — while s.56(3) reads "injury to any person including the driver". So a driver who injured only himself can owe a duty to report without ever having owed a duty to stop.

And the ordering of the penalties runs against intuition.

Failing to stop is a fine at level 3 and 12 months. Failing to report — or knowingly making a false statement in supplying the particulars — is a fine at level 4 and 6 months. The fine is higher for the reporting offence and the imprisonment is shorter. Under Schedule 8 to the Criminal Procedure Ordinance (Cap. 221), level 3 is $10,000 and level 4 is $25,000 — and s.113B(3) of the same Ordinance provides that the Chief Executive in Council may by regulation amend the amounts in Schedule 8 to reflect his opinion of the effect of inflation.

8. If the other side drew an assistance payment: a 72-hour duty attaching to the act of paying

The Traffic Accident Victims (Assistance Fund) Ordinance (Cap. 229) contains a duty that attaches to the act of paying rather than to the act of settling — which matters to someone who is thinking about handing over money directly.

Note the gate first: the duty arises only where the claimant has already notified you under s.9(1)(b) of the amount he received from the fund. No notification, no duty. The fund itself and the eligibility rules, deadlines and rates of the assistance scheme are in our crash-scene checklist guide.

The penalty. The Ordinance states levels, not cash sums:

A fine at level 1 is $2,000 today under Schedule 8 to Cap. 221, and s.113B(3) lets the Chief Executive in Council amend that Schedule by regulation.

One subsection runs the other way and is counter-intuitive:

In other words: the fact that the other side drew an assistance payment does not by itself reduce what you may be held liable for. The fund recovers from the recipient under s.10(1) — and an amount not so paid is recoverable as a debt due to the Government under s.10(3) — rather than by shrinking the tortfeasor's bill.

9. What the law requires you to say — and what is not on either list

There are two places where the law sets out exactly what must be given, and neither list contains a single item about how the accident happened.

The first list is at the scene. Cap. 374 s.56(2):

Three items, and it is a closed list: your name and address, the owner's name and address, and the vehicle's registration or identification mark or number. And it is owed "if required" — the subsection does not require a driver to volunteer anything. Nor is the person entitled to require them confined to the police: "any person having reasonable grounds for so requiring" can ask. But s.56(6) makes it an offence to knowingly make a false statement in supplying those particulars: you may not have to speak, but what you do say has to be true.

The second list arises after a claim is made — but note what triggers it. ⚠ Not the arrival of a letter, but a demand by or on behalf of the person making the claim. A solicitor's letter may contain that demand or may not; the duty starts only if it does. Cap. 272 s.13:

Two points. First, what triggers the duty is a demand by or on behalf of the person making the claim, not anything you choose to do; and the claim must be in respect of the liability that s.6(1)(b) requires to be covered — death or bodily injury — before the section engages at all. Second, what has to be given is only two things: whether you were insured in respect of that liability, and the particulars specified in the certificate of insurance. Nothing about how the accident happened. The offence in s.13(2) is punished under the general penalty in s.19(1) — a fine at level 1 and 3 months' imprisonment, with the level movable by the Chief Executive in Council under Cap. 221 s.113B(3).

Both duties are duties of identification, not duties of account. The legislature separated who you are and who insures you from what happened, and made only the first compulsory.

On reporting to an insurer: from the same written reply of 25 February 2026, quoted in section 4: policyholders are reminded to report immediately on receiving a summons for a traffic offence or a notice of a case reported to the police. A solicitor's letter is not on that list; but another paragraph of the same reply (section 4) is much wider: the Insurance Authority encourages policyholders to report known traffic-related accidents to their insurers as soon as practicable to safeguard their policy interests.
