Unless supervised administration is sought and ordered, each person interested in an estate, including a personal representative, whether appointed informally or after notice, may make 1 or more independent requests to the court so that a question or assumption relating to the estate, including the status of an estate as testate or intestate, a matter relating to 1 or more claims, a disputed title, an account of a personal representative, and distribution, may be resolved or established by adjudication after notice without necessarily subjecting the estate to the necessity of a judicial order in regard to other or further questions or assumptions.
