At least one year before the end of the concession or its renewal, the mayor or their delegate or the competent authority for the autonomous municipal government prepares a document that reminds the applicant that a renewal application must be sent before the established date. A copy of the document is sent to the concession holder, or, if they have passed away, the current rights holder. A copy of the document is displayed for at least one year at the plot and at the entrance to the cemetery. Successive renewals may be granted, should a relevant individual so request before the expiry of the established period. No renewal can exceed the duration of the initial concession.
