La. Stat. tit. 9 § 3131
The legislature finds and declares that the public policy of this state favors the marketability of immovables and the transferability of interests in immovables free of title defects or unreasonable restraints on alienation. The legislature further finds and declares that private transfer fee obligations violate this public policy by impairing the marketability and transferability of immovables and by constituting an unreasonable restraint on alienation regardless of the duration of the obligation to pay a private transfer fee, the amount of a private transfer fee, or the method by which any private transfer fee is created or imposed. Thus, the legislature finds and declares that a private transfer fee obligation shall not create real rights and shall not be binding on subsequent owners of immovables or other third parties, whether or not evidenced by a recorded instrument.
