Whether A.P.________'s challenge to the heir certificate was filed within the statutory time limit and was sufficiently formulated as an appeal.
The filing was out of time and the earlier letter did not contain a contestation capable of constituting an appeal.
The 15 January 2014 notice clearly warned that silence would result in issuance of the heir certificate to R.________. The 5 December 2014 submission was therefore late. The 21 November 2014 letter merely mentioned health problems and failure to accept the succession in time; it did not contest the certificate decision.
