Probate courts are usually trial courts with the authority to hear only matters relating to wills, estates, probate, guardianships, and conservatorships. Courts dedicated to these matters are usually located in populous counties and are said to have exclusive jurisdiction (authority) over such matters within the county.
In Washington State, probate matters are not handled by separate probate courts. Instead, these issues are dealt with by the Superior Courts, which serve as the trial courts of general jurisdiction. The Superior Courts have the authority to hear a variety of cases, including those related to wills, estates, probate, guardianships, and conservatorships. While there are no courts in Washington with the title 'Probate Court,' the Superior Courts effectively fulfill this role and have exclusive jurisdiction over such matters within their respective counties. This means that any legal issues concerning the administration of a deceased person's estate, the validity of a will, or the appointment of guardians or conservators for minors or incapacitated adults are addressed by the Superior Court in the county where the matter arises.
