Any person interested in any will who wishes to contest the validity of or rejecting of the will shall petition the Tribal Court within four (4) months immediately following the notice of approval or rejection of the will. The petition shall contain his objections and exceptions to said will, or to the rejection thereof. Issues respecting the competency of the deceased to make a last will and testament, or respecting the execution by a deceased of the last will and testament under restraint or undue influence or fraudulent representations, or for any other cause affecting the validity of the will or a part of it, shall be tried and determined by the Court. If no person shall appear within the time under this section, the approval for probate or rejection of such will shall be binding and final. [Res. 06-R-53 § (A)(35.09.010), 5/3/2006.]
