Yes. Montana has adopted the Uniform Probate Code, which validates a will under any of three tests: it complied with the law of the place of execution, the law of the testator's domicile when signed, or the law of the testator's domicile at death (UPC § 2-506). A will signed in another state is recognized in Montana if any of those tests passes. The practical wrinkle is the self-proving affidavit — if the foreign will doesn't have one, witnesses may need to testify during probate. See the Montana document portability tool for the full breakdown.
