The formal judicial proceeding to prove or confirm the validity of a will. The will is presented to the probate court, and creditors and interested parties are notified to present their claims or to show cause why provisions of the will should not be enforced by the court. Title to real property vests in the heirs or devisee, without the need for any court order, usually upon proof of the validity of the will. Even if the decedent dies without a will, his estate is still subject to a probate action. The court determines the rightful heirs, pays legal claims of creditors, and appoints an administrator to distribute the real and personal property according to the court’s decree.
