(1) The determination is to be preceded by a public invitation to register the rights of succession, specifying a period of time for such registration; the type of the notice given by publication and the length of the registration period are governed by the provisions governing judicial call procedure. The invitation may be omitted if the costs are disproportionately high with regard to the amount of the estate.
(2) A right of succession is not taken into account if it is proved to the probate court within three months after the expiry of the notification period that the right of succession exists or that it has been asserted against the treasury in a legal action. If there has been no public invitation, the three-month period begins when the judicial invitation to prove the right of succession or the filing of the claim is made.
