probate

The judicial procedure by which a [wex:testamentary] document is established to be a valid will.

Unless set aside, the probate of a will is conclusive upon the parties to the proceedings, and others who had notice of the proceedings, on all questions of [wex:testamentary capacity], the absence of [wex:fraud] or [wex: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.
