As long as prescription of the right to accept has not been acquired against him, the heir may revoke his renunciation by accepting the succession purely and simply, if it has not already been accepted by another heir or if the State has not already been sent into possession.
Such acceptance is retroactive to the day on which the succession was opened, without, however, calling into question any rights that may have been acquired by third parties in the property of the succession by prescription or by acts validly done with the curator of the vacant succession.
