The Unfair Terms in Consumer Contracts Directive 93/13/EEC is a European Union directive (then called European Economic Community directive) governing the use of surprising or onerous terms used by business in deals with consumers.

Unfair terms in consumer contracts are declared void by paragraph 209/A(2) of the Hungarian Civil Code, which also states in paragraph 209(1) that

A standard contractual term or a contractual term not negotiated individually in a consumer contract shall be unfair if it establishes the rights and obligations of the parties arising from the contract unilaterally and unjustifiably, in breach of the requirements of good faith and fairness and to the detriment of the party to the contract who did not draw up that term.^[1]

Paragraph 2(d) of Government Decree 18/1999 (II. 5.) on terms to be considered unfair in consumer contracts, dated 5 February 1999 (Magyar Közlöny 1999/8), states that

The terms of a consumer agreement must in particular be regarded as unfair, unless evidence is provided to the contrary, if they enable the party entering into the contract with the consumer to amend the contract unilaterally and without having to provide justification, particularly where that party increases the level of financial recompense defined in the contract, or if such terms enable the party entering into the contract with the consumer to amend the contract unilaterally on justified grounds as defined in the contract where the consumer is not entitled to terminate or cancel the contract with immediate effect.^[2]

In the United Kingdom the Unfair Terms in Consumer Contracts Regulations 1994^[3] and the Unfair Terms in Consumer Contracts Regulations 1999^[4] are UK statutory instruments, which implemented the EU's directive.^[5]
