Ambiguity Doctrine Law and Legal Definition

Ambiguity doctrine is a rule of contractual interpretation which provides, while interpreting documents, ambiguities are to be construed unfavorably to the drafter. The reasoning behind this rule is to encourage the drafter of a contract to be as clear and explicit as possible and to take into account as many foreseeable situations as it can.

Ambiguity doctrine is also called Contra Proferentem Doctrine
