Contra Proferentem Doctrine

In case of doubt about the meaning of a written contract term, not individually negotiated, the terms is interpreted in favor of the person who contracted the obligation and against the person who stipulated it, because a person who produces a document had the capacity to avoid ambiguities. This principle has been clearly recognized in article 6 of CESL and article 8 of UPICC, and paragraph 3 of article 8 of CISG accepted this principle implicitly. Although this principle is not explicitly regulated in Iranian law but according to some principle of contract law like: the principle of fairne ss and equity, principle of goodwill, principle of observance of public order, principle of causation, principle of freedom of wills and principle of lack of misrepresentation, we can infer the Contra Proferentem Doctrine.
