If the prescription has commenced to run and the husband dies before the prescription has accrued, his successor whose interest is adversely affected may institute an action for disavowal of paternity. The action of the successor is subject to a liberative prescription of one year. This prescription commences to run from the day of the death of the husband.
If the prescription has not yet commenced to run, the action of the successor is subject to a liberative prescription of one year. This prescription commences to run from the day the successor is notified in writing that a party in interest has asserted that the husband is the father of the child.
