Contract interpretation is one of the most elusive and controver- sial issues in contract law. In that regard, this article firstly considers the question of when the declaration of will (intention) will be acquired, and issues relating to the interpretation of the declaration and the cont- ract interpretation in light of the trust theory in Turkish law. This article then examines literal, subjective and objective approaches to the interp- retation of contracts by taking the approaches adopted in Swiss and German laws into account and subsequently outlines the main approach applied in Turkish contract law. After this, the article discusses the pre- vailing interpretation method in English contract law, which differs from that of Turkish law, and explains how this different approach to contract interpretation affects the result arrived at in English law. The last part of this article spells out similarities and differences between the appro- aches to contract interpretation in Turkish and English law, and argues that there is a need for a change in the approach to contract interpreta- tion in English law.
