Article 2398. More than one share of the inheritance
(1) A person who is entitled to more than one share of the inheritance may, if the entitlement is based on more than one ground, accept one share of the inheritance and disclaim the other.
(2) Where the entitlement is based on the same ground, the acceptance or disclaimer of one share of the inheritance also applies to the other, even if the other devolves only later. The entitlement is based on the same ground even if it is directed in more than one will.
(3) If the deceased leaves an heir more than one share of the inheritance, it may permit the heir by disposition mortis causa to accept one share of the inheritance and disclaim the other.
