Once an insured event has occurred, the relationship between insurer and policyholder becomes a claims relationship. The Law of Obligations Act (võlaõigusseadus, VÕS) regulates the policyholder's duties at this stage (notification, information, mitigation, preservation of evidence) and the insurer's duties (investigation without delay, payment when due, interim payment).1 For liability insurance there are special rules on notification of circumstances and claims (§ 514). Foreign claims guidelines often assume that late notice or non-cooperation automatically defeats the claim. Under Estonian law that is rarely the case.
The timeline is the general rule for insurance contracts. Liability and motor insurance have special rules (see below).
- Day 0Insured event as defined in the policy Statutory rule
The policyholder notifies without delay (Law of Obligations Act (võlaõigusseadus, VÕS) § 448(1)).
Exception On breach, the indemnity may be reduced to the extent of the insurer's loss; on intentional breach the insurer is released (§ 449).
- AssessmentInsurer's necessary steps Statutory rule
The obligation to perform falls due when the steps needed to establish the event and the extent of performance are completed (§ 450(1)).
- 1 month after noticeMinimum amount Statutory rule
If the steps are not completed and the insured event is established, the policyholder may claim the amount the insurer should pay at a minimum (§ 450(3)).
- 2 months after noticeRequest for explanation Statutory rule
The policyholder may ask why the steps are not completed. If the insurer does not answer within one month, its obligation falls due (§ 450(2)); this does not mean the amount claimed is accepted.
- DecisionPayment or rejection Statutory rule
Receipt of a written rejection starts the one-year period for bringing an action, if the rejection stated its consequence (§ 475(3)).
Special rules
Liability insurance Statutory rule
Circumstances and claims to be notified within one week, commencement of proceedings without delay (VÕS § 514). Payment without delay and at the latest within two weeks of the claim being satisfied or established (§ 515(1)).
Motor insurance Statutory rule
Necessary steps within a reasonable time and at the latest on the 30th calendar day after notification; a delay for good reason must be notified in advance, and the period is extended where proceedings are pending (Motor Insurance Act (liikluskindlustuse seadus, LKindlS) § 39).
Legal basis: VÕS §§ 448–450, 475, 514–515; LKindlS § 39. Statutory text checked against the version in force on 9 November 2026.
1. Notification of the insured event (VÕS §§ 448–449)
The duty. The policyholder must notify the insurer of the occurrence of the insured event without delay after learning of it (§ 448 lg 1).1 Contracts often add a form (written notice, notice through a portal) and a fixed period. A contractual period is valid as a description of what "without delay" means, but not as a strict condition precedent.
Consequences of late notice (§ 449). If the policyholder breaches the notification duty and the insurer suffers damage as a result, the insurer may reduce its performance by the amount of that damage. The insurer is released entirely only where the breach was intentional (§ 449 lg 1–2).1 Whether an intentional but harmless delay may still release the insurer is debated; in the author's view the principle of good faith (VÕS § 6) and the purpose of the duty argue against release where the delay had no consequences at all. In practice the insurer must show what it would have done differently with timely notice, for example inspecting the damaged property, appointing an expert before repairs, or participating in a settlement with a third party.
Liability insurance. The policyholder must notify circumstances that may give rise to the insurer's liability and the assertion of a claim against him within one week of learning of them, and the commencement of proceedings and any circumstance that may form the basis of a claim against him without delay (§ 514 lg 1, 3). See liability insurance and direct action.
Claims-made and discovery triggers. In D&O, professional indemnity and crime insurance the notice of a claim or of a discovered loss is often part of the insuring clause. The question then is whether notice is an element of the insured event (a matter of risk description) or a post-loss obligation. Estonian law has not yet settled this for claims-made policies at Supreme Court level; the answer depends on the wording and on the standard-terms rules. Reporting periods that end shortly after expiry should be drafted transparently.
2. Information and evidence (VÕS § 448 lg 2)
After the insured event, the insurer may require the policyholder to provide information necessary to establish the insured event and the extent of the insurer's obligation, and evidence so far as the policyholder can reasonably be expected to obtain it (§ 448 lg 2).1
The Supreme Court has drawn two consequences from this provision. First, § 448 lg 2 does not change the burden of proof: the policyholder must prove the insured event, but the insurer cannot impose on him evidential requirements that cannot reasonably be met, for example a police certificate confirming a theft where the police do not issue such certificates.2 Secondly, the insurer may rely in court on grounds of refusal it did not mention in its decision letter; the decision letter does not limit its defences.3
3. Duty to prevent and mitigate loss (VÕS § 488)
In indemnity insurance the policyholder must, when the insured event occurs, take measures to prevent and reduce the loss, following the insurer's instructions and seeking them where possible. He must not alter the scene or the damaged property in a way that hinders establishing the cause or extent of the loss, unless the change is necessary to mitigate the loss or is in the public interest (§ 488 lg 1–2). If he breaches these duties, the insurer may reduce the indemnity by the damage caused to it (§ 488 lg 3).1
Mitigation costs (§ 491). The insurer must reimburse the expenses of measures the policyholder reasonably considered necessary, even if they were unsuccessful, and expenses incurred on the insurer's instructions even if they exceed the sum insured together with the indemnity; on request it must advance the amount needed for expenses to be incurred in accordance with its instructions (§ 491 lg 2, last sentence); other necessary mitigation expenses are reimbursed afterwards under the general rule. In under-insurance, mitigation costs are reimbursed in the same proportion (§ 491 lg 3). Necessary expenses of establishing the loss are reimbursed, but not the costs of experts and advisers the policyholder engaged without a contractual obligation (§ 491 lg 1).1
4. Establishing the loss and expert determination (VÕS §§ 489–490)
The insurer must establish the amount of the loss without delay. If the parties do not agree, either may ask the court to determine it. The insurer's participation in establishing the loss does not mean that it accepts liability. A clause restricting the policyholder's right to use a representative in establishing the loss is void (§ 489).
An agreement that the amount of loss will be determined by an expert is valid only if the expert is appointed by an independent third party or both parties appoint an equal number of experts. A determination is not binding if it manifestly and substantially deviates from the actual circumstances (§ 490).1 Appraisal clauses in London and US wordings ("each party appoints an appraiser, the appraisers appoint an umpire") are generally compatible with § 490 if the umpire is neutral.
5. When the indemnity falls due (VÕS §§ 450–451)
- Due date. The insurer's monetary performance falls due when the insured event has occurred and the procedures necessary to establish the extent of performance have been completed (§ 450 lg 1).
- Forcing a decision. If the procedures have not been completed within two months of notification, the policyholder may ask for an explanation; if the insurer does not respond within one month, the claim falls due (§ 450 lg 2).
- Payment on account. If the insured event has been established but the procedures needed to determine the amount have not been completed within one month of notification, the policyholder may demand, on account of the insurer's obligation, payment of the amount the insurer should at least pay in the circumstances. The period is suspended while completion of the procedures is prevented by a circumstance attributable to the policyholder (§ 450 lg 3). There is no such right while the insured event itself is unestablished; a dispute only about quantum does not exclude it.
- Liability insurance. The insurer must pay within two weeks after the injured party's claim has been satisfied by the policyholder or established by judgment, acknowledgement or settlement, and must pay costs under § 511 within two weeks of notification of their total amount (§ 515 lg 1).
- Late payment interest. An agreement releasing the insurer from late payment interest is void (§ 451).1
The Supreme Court has held that the insurer can be ordered by way of interim relief to pay an amount that is clearly payable at a minimum, but that the threshold for such an order is high (see Supreme Court: procedure).
6. Fraudulent claims
Estonian insurance contract law has no general statutory rule comparable to s 12 of the English Insurance Act 2015 on fraudulent claims. The consequences of a fraudulent claim follow from:
- the post-loss obligation regime (§ 452 lg 2 p 3–4: the insurer may rely on an agreed release for breach of a post-loss obligation only if the breach was intentional (p 3), or grossly negligent and had an effect on establishing the insured event or on the insurer's obligation (p 4); for an intentional breach the statute itself does not require such an effect, so any limit on release in that case comes from the principle of good faith, which is assessed separately);
- clauses in the wording, assessed under §§ 42 and 452;
- the general principle of good faith (VÕS § 6);
- criminal law (insurance fraud is a criminal offence under § 212 of the Penal Code (karistusseadustik, KarS)).4
A wording that forfeits the entire claim for any exaggeration should be drafted carefully. The safer course is to provide for release with respect to the claim tainted by intentional misrepresentation.
7. Practical guidance
- Treat notice provisions as obligations, not as conditions precedent, and document any prejudice from late notice.
- Keep information requests proportionate; explain why each document is needed.
- Instruct the policyholder on mitigation in writing and agree advance payment of mitigation costs where appropriate.
- Respond to a § 450 lg 2 request within one month. Where the insured event is established and only the amount is open after one month, pay the minimum amount on account under § 450 lg 3, and record any delay caused by the policyholder.
- In the decision letter, include the one-year warning under § 475 lg 3 (see limitation).
