Louisiana Civil Code Tit. XX-A, Art. 3169. Effectiveness against third persons

The pledge of the lessor's rights in the lease of an immovable and its rents is without effect as to third persons unless the contract establishing the pledge is recorded in the manner prescribed by law.

Nevertheless, the pledge is effective as to the lessee from the time that he is given written notice of the pledge, regardless of whether the contract establishing the pledge has been recorded.
