Which court has the authority to oversee matters concerning estates?

The correct answer is probate court, as this specialized court is specifically designed to handle matters related to estates, including the validation of wills, the administration of estates, and the distribution of assets after an individual's death. Probate court deals with all aspects of the probate process, which may include appointing executors, managing estate debts, and resolving disputes among heirs or beneficiaries regarding the estate.

Other courts, while they may have jurisdiction over certain related issues, generally do not have the specific authority or procedures in place that probate courts have for handling estate matters. Family courts primarily handle issues related to family law such as custody, divorce, and child support, while circuit and district courts may address civil or criminal cases without the specialized focus on probate law. Thus, probate courts are the critical venue for navigating the often complex legal considerations surrounding estates.
