21 GCA § 25101: Action to Quiet Title to Real and Personal Property.

An action may be brought by any person against another who claims an estate or interest in real or personal property, adverse to him, for the purpose of determining such adverse claim, provided however, that whenever in an action to quiet title to, or to determine adverse claims to, real or personal property, the validity or interpretation of any gift, devise, bequest, or trust, under any will, or instrument purporting to be a will, whether admitted to probate or not, shall be involved, such will, or instrument purporting to be a will, is admissible in evidence; and all questions concerning the validity of any gift, devise, bequest, or trust therein contained, save such as belong exclusively to the probate jurisdiction, shall be finally determined in such action; provided, that if the said will shall have been admitted to probate and interpreted by a decree of the Superior Court sitting in probate, which decree has become final, such interpretation shall be conclusive as to the proper construction of said will, or any part thereof, so construed, in any action under this section.
