In common-law and equity actions relating to decedents' estates, the county courts have concurrent original jurisdiction with the district courts. When the jurisdiction of the county court and district court is concurrent, the basic principles of judicial administration require that the court which first acquires jurisdiction should retain it to the exclusion of the other court. Washington v. Conley, 273 Neb. 908, 734 N.W.2d 306 (2007).
To the extent permitted by the Nebraska Constitution, the county court has jurisdiction over all subject matter relating to estates of decedents, including the determination of heirs, subject to administration. Mischke v. Mischke, 253 Neb. 439, 571 N.W.2d 248 (1997).
