Renunciation is express.
It may also result from the law. Express renunciation is made by notarial act en minute or by a judicial declaration which is recorded. A person who renounces is deemed never to have been a successor. A successor who has renounced the succession retains the faculty of accepting it for ten years from the day his right arose, if it has not been accepted by another person. Acceptance is made by notarial act en minute or by a judicial declaration which is recorded.
