The option is time-barred after ten years from the opening of the succession.
An heir who has not taken sides within this period is deemed to have renounced.
Time-barring only runs against an heir who has left the surviving spouse in possession of the hereditary property from the opening of the latter’s succession.
The limitation period does not run against the subsequent heir of an heir whose acceptance is annulled until the final decision establishing this nullity.
The limitation period does not run as long as the successor has legitimate reasons for not knowing that his right arose, in particular the opening of the succession.
