What Applies to Unfair Contract Terms in Sweden? – Legal Advice

When two parties sign a contract, the general rule is that they’re bound by the terms they’ve agreed to. But what if a clause is clearly unreasonable, unbalanced, or abusive? Under Swedish law, there are legal protections against such terms—known as unfair contract terms.

.

In this article, we explain what is considered unfair under Swedish contract law, how courts handle such clauses, and what you can do if you’re faced with an unfair agreement.

What Is an Unfair Contract Term?

An unfair contract term is a clause that is so unreasonable or one-sided that it should not be enforceable under the law. Examples include:

.

  • Excessively high fees or penalties

  • Clauses that favor one party disproportionately

  • Waivers of key rights (e.g., no right to complain or claim damages)

  • Hidden terms in standard contracts

.


.

What Does the Law Say?

Under Section 36 of the Swedish Contracts Act (Avtalslagen 1915:218), a contract term may be adjusted or declared invalid if it is unfair, considering:

.

  • The content of the agreement

  • How the agreement was formed

  • Any changes in circumstances

  • The relative strength of the parties

.

This gives Swedish courts broad discretion to modify or strike down unfair clauses—or even the entire agreement, in extreme cases.

Examples of Unfair Terms

  • A company denies the consumer any right to return or complain about a defective product

  • A standard form includes a penalty of SEK 500,000 for minor delays

  • A business excludes its liability for personal injury

What Applies in Consumer Contracts?

Consumers are particularly protected under Swedish law. According to the Act on Terms in Consumer Contracts (1994:1512), unfair terms are not allowed, even if the consumer agreed to them.

.

The Swedish Consumer Agency (Konsumentverket) has the authority to investigate and prohibit the use of unfair terms in standard agreements.

How Do Courts Assess Whether a Term Is Unfair?

Swedish courts carry out a case-by-case assessment, taking into account:

.

  • Whether the agreement was individually negotiated or pre-written

  • If the party had a real chance to understand the clause

  • Whether one party had significantly stronger bargaining power

  • Whether the term is disproportionate to its intended purpose

What Can You Do If You Encounter an Unfair Term?

  1. Object in writing – Let the other party know you do not accept the term.

  2. Negotiate – Ask for the term to be revised before signing.

  3. Seek legal advice – Especially for high-value or long-term contracts.

  4. Refuse to comply with the term – But do this carefully and with legal support.

  5. Take it to court – If the other party insists on enforcing an unfair clause.

Summary

A contract term can be formally valid but legally unenforceable if it is considered unfair. Swedish law allows both consumers and businesses to challenge abusive or clearly unreasonable clauses.

.

If you come across a contract term that seems unfair—get legal advice before signing or performing the contract. It could save you from costly consequences or future disputes.
