What Are Unfair Contract Terms: Complete Guide 2026

What Are Unfair Contract Terms?

Unfair contract terms are contractual provisions that create a significant imbalance between the rights and obligations of the parties, to the detriment of the consumer. According to the Consumer Code (Legislative Decree 206/2005, Articles 33-38), a term is considered unfair if, even in good faith, it materially alters the contractual balance.

Double Signature for Vexatious Clauses: Art. 1341-1342 of the Italian Civil Code

The procedure for validating disadvantageous clauses in standard-form contracts involves two steps:

1 Primary Signature: General signature for acceptance of the entire contract.

2 Secondary Signature (Double Signature): Specific and separate approval for only the identified vexatious clauses in writing. Without this, the clauses are void.

The European Regulatory Framework on Unfair Contract Terms

Council Directive 93/13/EEC establishes that contract terms not individually negotiated are considered unfair if, contrary to the requirement of good faith, they cause a significant imbalance in the parties' rights and obligations, to the detriment of the consumer.

In 2026, with the entry into force of the European AI Act, new categories of potentially unfair terms related to the use of artificial intelligence in digital services are emerging. According to a study by the University of Bologna published in January 2026, 41% of digital service contracts updated after 2025 include clauses authorizing the use of user data for training AI models — often without explicit and separate consent.

Frequently Asked Questions

How do I know if a clause is unfair?

A clause is presumptively unfair if it: limits your liability but not the company's, allows unilateral price changes, imposes a competent court far from your residence, or excludes the right of withdrawal. Tools like NakedPact automatically highlight these clauses in seconds.

Are unfair terms always void?

Under European law, unfair terms not individually negotiated are considered non-binding on the consumer. The remainder of the contract remains valid if it can continue to exist without the unfair term.
