To be valid and effective, a will must be in writing, dated, and signed by the testator or some other person under the testator’s authority and direction in the presence of the testator. The will shall be attested by two or more adult competent witnesses, not having an interest in the testator’s estate or in the will, signing their names to the will in the presence of the testator by the testator’s direction or request; provided, that a will executed outside the Reservation, in the mode prescribed by applicable law, either of the place where executed or of the testator’s domicile, shall be deemed to be legally executed, and shall be of the same force and effect as if executed in the mode prescribed by the laws of the Tribe.
