Nebraska Revised Statutes Chapter 30. Decedents' Estates; Protection of Persons and Property § 30-2465. Personal representative to proceed without court order;  exception

A personal representative shall proceed expeditiously with the settlement and distribution of a decedent's estate and, except as otherwise specified or ordered in regard to a supervised personal representative, do so without adjudication, order, or direction of the court, but he may invoke the jurisdiction of the court, in proceedings authorized by this code, to resolve questions concerning the estate or its administration.

If no return be made, the case may be heard on the papers of the applicant. If the return raises only questions of law, or puts in issue immaterial statements, not affecting the substantial rights of the parties, the court must proceed to hear or fix a day for hearing the argument of the case.

If a petition for a writ of mandate filed pursuant to Section 1088.5 presents no triable issue of fact or is based solely on an administrative record, the matter may be determined by the court by noticed motion of any party for a judgment on the peremptory writ.
