La. Civ. Code art. 3164
Current with operative changes from the 2024 Third Special Legislative Session
The parties to a contract from which a pledged obligation arises may agree to modify or terminate the contract or to substitute a new contract. If made in good faith, the agreement is effective against the pledgee without his consent. Nevertheless, after written notice of the pledge is given to the obligor of a pledged obligation that has been fully earned by the pledgor's performance, an agreement modifying or extinguishing the pledged obligation is without effect against the pledgee unless made with his consent.
