La. Civ. Code art. 3501
A money judgment rendered by a trial court of this state is prescribed by the lapse of ten years from its signing if no appeal has been taken, or, if an appeal has been taken, it is prescribed by the lapse of ten years from the time the judgment becomes final.
An action to enforce a money judgment rendered by a court of another state or a possession of the United States, or of a foreign country, is barred by the lapse of ten years from its rendition; but such a judgment is not enforceable in this state if it is prescribed, barred by the statute of limitations, or is otherwise unenforceable under the laws of the jurisdiction in which it was rendered.
Any party having an interest in a money judgment may have it revived before it prescribes, as provided in Article 2031 of the Code of Civil Procedure. A judgment so revived is subject to the prescription provided by the first paragraph of this Article. An interested party may have a money judgment rendered by a court of this state revived as often as he may desire.
