The judicial procedure through which the testamentary document is established to be a valid will; the proving of a will to the satisfaction of the court. Unless it’s set aside, the probate of a will is conclusive upon the parties to the proceedings (and others who had notice of them) on all questions of testamentary capacity, the absence of fraud or undue influence, and due execution of the will. Probate does not preclude inquiry into the validity of the will’s provisions or on their proper construction or legal effect.
