La. Civ. Code art. 2057
Current with changes from the 2024 Legislative Session
In case of doubt that cannot be otherwise resolved, a contract must be interpreted against the obligee and in favor of the obligor of a particular obligation.
Yet, if the doubt arises from lack of a necessary explanation that one party should have given, or from negligence or fault of one party, the contract must be interpreted in a manner favorable to the other party whether obligee or obligor.
