Standard terms in Estonia: when they bind you and when they are void

What counts as a standard term under Estonian law?

Form does not matter. Standard terms can sit in the signed contract itself or in a separate document, whatever their length or presentation (§ 35(3)). An agent’s lease template, a client’s purchase terms and a platform’s terms of service can all be standard terms, even when you sign them.

Because of the presumption, a party that wants to escape standard-terms control has to show that a clause was genuinely negotiated, so keep the e-mails in which you asked for changes. A negotiated clause is still subject to the general rules, such as the limits on excluding liability for intentional breach (§ 106(2)).

The rules cannot be switched off: an agreement that departs from § 35–39 or § 41–45 to the detriment of the other party is void (§ 35(5)). They do not apply to inheritance and family law contracts, or to contracts founding companies or other legal persons or organising their management (§ 36(1)).

When do standard terms become part of the contract?

For websites and apps, this is why a checkbox or a notice next to the order button with a working link to the terms matters. Terms that sit only in a page footer, or first appear on an invoice after the deal is done, may fail the § 37(1) test.

A business contracting online must also provide the terms, including standard terms, in a form you can save and reproduce (§ 62¹(5)). Keep a PDF of the version you accepted, because the website may change.

Parties can agree in advance that certain standard terms will govern future contracts of a given type, for example in a framework agreement, as long as the same reference and access requirements are met (§ 37(2)).

What are surprising terms, and how are unclear terms read?

Small print in a service contract obliging you to buy an unrelated product is the kind of term this rule catches. If a standard term conflicts with a term the parties agreed separately, the separate agreement wins (§ 38), so a payment deadline negotiated by e-mail beats the one in the template.

Standard terms are read as a reasonable person in your position would have understood them, and any remaining doubt is resolved against the party that used them (§ 39(1)). A void term cannot be saved by reading it more narrowly, although independent parts of a clause can survive (§ 39(2)).

If two businesses each refer to their own conflicting terms, the contract is made on the terms that do not conflict and the law fills the gaps (§ 40(1)). A party that clearly says, other than in its standard terms, that it does not regard the contract as made can avoid this, unless it has already performed or accepted performance (§ 40(2)).

Which standard terms are void under VÕS § 42?

Unreasonable harm is presumed where a term departs from an essential principle of the law or restricts rights so much that the purpose of the contract is put at risk (§ 42(1)). A term is not unfair merely because it concerns the main subject of the contract or the ratio of price to value, or because it reflects a mandatory legal rule (§ 42(2)).

Section 42(3) lists terms that are unfair in consumer contracts. They include terms that exclude liability for death, injury, intent or gross negligence (point 1); exclude or unreasonably limit remedies, including set-off (point 2); impose an unreasonably high penalty or fixed damages (point 5); set an unreasonably short deadline for claims (point 9); make going to court unreasonably difficult (point 10); allow unilateral changes for a reason not stated in the law or the contract (point 14); allow price rises without a right to terminate, except lawful indexation (point 15); renew a contract automatically for more than a year (point 27); give only the user a right to terminate without reason (point 29); or treat your act or silence as a declaration, unless you are told what it means and given reasonable time to respond (point 37).

How do the rules differ in B2B contracts?

The general test in § 42(1) still applies, and reasonableness is judged with regard to the customs and practices of the trade (§ 7(2)). For a freelancer or small OÜ signing a large client’s template, a clause excluding your remedies, a termination right for the client alone or an excessive penalty can still be challenged.

Where both parties act in business and their places of business connected with the contract are in Estonia, the Estonian standard-terms rules apply whatever law the contract chooses (§ 36(3)). For consumers, they can apply despite a foreign-law clause if the consumer lives in the EU and the contract resulted from an offer or advertising in Estonia (§ 36(2)).

Associations representing businesses can demand that a business stop using grossly unfair terms on payment periods, late-payment interest or recovery costs, even negotiated ones (§ 45(2¹)). In consumer contracts, TTJA can ask a court to ban unfair standard terms, and using a § 42(3) term is a misdemeanour with fines of up to €400,000 for a company (Consumer Protection Act (TKS) § 21(2), § 74¹).

What happens when a standard term is void?

Because a void term cannot be given valid content by interpretation (§ 39(2)), a void penalty clause falls away entirely rather than being cut down to a reasonable level.

A void term has no legal effect from the outset (General Part of the Civil Code Act (TsÜS) § 84(1)), but if the other side relies on it, you may need to argue the point in writing, citing the section.

Fixing a problem clause before signing is cheaper than arguing about it later: ask for separately agreed wording, which overrides the template (§ 38). Upload the contract for a free risk summary that flags clauses that may be void under § 42, and have an Estonian lawyer review high-value or complex contracts.
