Can stepchildren or domestic partners inherit without a will in Michigan?

Under Michigan intestacy law, stepchildren and unmarried partners do not inherit unless legally adopted or otherwise recognized by statute (MCL § 700.2102). Only legally recognized spouses and blood or adopted relatives are included in the intestate succession order. A will or trust is the only way to provide for stepchildren or unmarried partners.
