La. Code Civ. Proc. art. 4554
Current with operative changes from the 2024 Third Special Legislative Session
On motion of the court or any person, including the interdict, the court may modify or terminate its judgment when the court finds, by a preponderance of the evidence, that the terms of that judgment are currently either excessive or insufficient or that the ability of the interdict to care for his person or property has so changed as to warrant modification or termination. Except for good cause, the court shall follow substantially the same procedures that apply to an original petition for interdiction before it modifies or terminates an interdiction judgment.
