Rule 5.312 - Reopening Decedent Estate(A) Reopening by Application. If there is good cause to reopen a previously administered estate, other than an estate that was terminated in supervised administration, any interested person may apply to the register to reopen the estate and appoint the former personal representative or another person who has priority. For good cause and without notice, the register may reopen the estate, appoint the former personal representative or a person who has priority, and issue letters of authority with a specified termination date.(B) Reopening by Petition. The previously appointed personal representative or an interested person may file a petition with the court to reopen the estate and appoint a personal representative under MCL 700.3959.(C) Calculation of Due Dates. For purposes of determining when the inventory fee calculation, the inventory filing, the inventory fee payment, and the notice of continued administration are due, a reopened decedent estate is to be treated as a new case.
