Louisiana Civil Code Tit. III, Art. 1900. Assignment by obligee

An obligor who has consented to an assignment of the credit by the obligee to a third person may not claim against the third person any compensation that the obligor otherwise could have claimed against the obligee.

An obligor who has been given notice of an assignment to which the obligor did not consent may not claim compensation against the assignee for an obligation of the assignor arising after that notice.
