Ending an insurance contract in Estonia: nullity to cancellation

English-language insurance practice uses "rescission", "avoidance", "termination", "cancellation" and "repudiation", often interchangeably. None of these words has an automatic one-to-one Estonian equivalent. Estonian law has distinct institutions, each with its own trigger, form, deadline and consequence. Choosing the wrong one, or describing the right one with the wrong word, is a frequent cause of failed declinations. This page explains the institutions by their legal consequence. The terminology used in the official English translation of the Law of Obligations Act (võlaõigusseadus, VÕS) is noted where relevant.¹

1. Overview

2. Nullity (tühisus)

A void transaction has no legal effect from the outset, without any declaration (General Part of the Civil Code Act (tsiviilseadustiku üldosa seadus, TsÜS) § 84).² In insurance, nullity arises for example where:

• the policyholder concluded multiple insurance with the intention of obtaining an unlawful pecuniary benefit (VÕS § 486 lg 4);
• the contract violates a statutory prohibition, including transactions contrary to international sanctions (see sanctions and insurance);
• a specific clause is void, for example a clause deviating from a semi-mandatory provision (VÕS § 427 lg 1) or an unfair standard term (§ 42). Here only the clause is void and the contract survives (§ 41).

3. Avoidance (tühistamine)

Avoidance is a unilateral declaration by which a party eliminates a transaction concluded under the influence of mistake, fraud, threat or violence (TsÜS §§ 90–99). Once avoided, the transaction is deemed void from the outset and performance is returned under the rules on unjustified enrichment (TsÜS § 90).² In insurance, the relevant ground is mainly fraud by the policyholder (TsÜS § 94; VÕS § 441 lg 5). The declaration must be made within six months of learning of the ground; avoidance for mistake or fraud is excluded after three years from the transaction (TsÜS § 99).

In a case on the compulsory liability insurance of a bankruptcy trustee, the Supreme Court held that an avoided insurance contract cannot be relied on by third parties either, so that the injured party cannot invoke § 521 lg 5 against an insurer that has validly avoided the contract; in that case the insurer had not in fact avoided the contract (RKTKo 15.10.2025, 2-21-16822/84, para 13).³ The statement cannot be extended without qualification to every compulsory insurance: in motor third-party liability insurance, EU law generally prevents the insurer from relying against the victim on the invalidity of the contract resulting from the policyholder's pre-contractual misrepresentation (CJEU C-287/16, Fidelidade; C-236/23, Matmut, paras 47 and 66, with an exception for abuse of rights).

4. Withdrawal (taganemine)

Withdrawal from an insurance contract is permitted only in the cases provided by law (VÕS § 466).¹ The main cases are:

• Insurer: breach of the pre-contractual disclosure duty (§§ 441–442) and unpaid first premium (§ 457).
• Policyholder: the cooling-off right (§ 433, § 56), see distance contracts and withdrawal.

Under the general part of VÕS, withdrawal releases the parties from performing their obligations and entitles them to restitution (§ 188). The insurance chapter adjusts these consequences: after an insured event, the insurer that withdraws for non-disclosure must still pay unless the circumstance was causal (§ 442 lg 2), and the insurer is entitled to premium for the time elapsed (§ 459). See pre-contractual disclosure.

5. Cancellation (ülesütlemine)

Cancellation ends a continuing contract for the future. Insured events that occurred before the cancellation took effect remain covered, subject to any release defence. The main grounds are:

Clauses that automatically extend the contract by more than one year at a time are void (§ 467). If the insurer may withdraw or cancel only in respect of some insured objects or persons, it may extend this to the remainder only where it would not have insured the remainder on the same terms (§ 474).¹

6. Release, reduction and absence of cover: not ways of ending the contract

Release from the performance obligation, reduction of the indemnity and absence of cover are defences to a particular claim; the contract continues. They are often confused with termination in foreign declination templates. Their legal bases are:

• Release: unnotified aggravation (§ 445), intentional breach of the notification duty (§ 449 lg 2), qualified breach of obligations (§ 452 lg 2), unpaid premium (§§ 457–458), intentional causation (§ 452 lg 1, § 513).
• Reduction: prejudice from late notice (§ 449 lg 1), breach of mitigation duties (§ 488 lg 3), under-insurance (§ 482), proportional release for breach of safety obligations (§ 452 lg 2, as interpreted since 2024).⁴
• Absence of cover: the event is outside the insuring clause or within a genuine exclusion (see exclusions vs obligations).

7. Writing the declaration

A declaration under Estonian law should:

1. name the institution in Estonian legal terms and the statutory basis (for example "withdrawal under VÕS § 441 lg 1" or "cancellation under VÕS § 470 lg 1");
2. state the facts on which it is based and when the insurer learned of them;
3. state the effect claimed (ex tunc, ex nunc, release for a specific event);
4. where a claim is refused, include the warning required by VÕS § 475 lg 3 (see limitation);
5. be sent in a form that can be proven, to the policyholder's last known address or agreed electronic address.

Combining alternatives is possible and often advisable ("primarily we avoid the contract for fraud under TsÜS § 94; alternatively we withdraw under VÕS § 441; in any event we refuse the claim because..."), provided each alternative meets its own deadline.
