The UK Unfair Terms in Consumer Contracts Regulations 1999 [1] are reasonably good in this regard IMO. It gives effect to an EU directive, so most/all EU countries should have similar protection. Summary of major provisions: > s.8(1) - An unfair term in a contract concluded with a consumer by a seller or supplier shall not be binding on the consumer. > s.5(1) - A contractual term which has not been individually negotiated shall be regarded as unfair if, contrary to the requirement of good faith, it causes a significant imbalance in the parties' rights and obligations arising under the contract, to the detriment of the consumer. > s.7(1) and s.7(2) - A written term must be in plain intelligible language. Any doubt is resolved in the customer's favour. [1] http://www.legislation.gov.uk/uksi/1999/2083/contents/made http://www.legislation.gov.uk/uksi/1999/2083/contents/made
