Yes. Michigan 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). The practical wrinkle is the self-proving affidavit: without one, the witnesses may need to testify when the will enters probate. The Michigan document portability tool carries the recognition rule by document type.
