Unmarried fathers in Michigan have no automatic legal rights to custody or parenting time. You must act to establish them — and the clock starts the moment your child is born.
Michigan law does not automatically recognize an unmarried father's parental rights. Unlike a married father — who is presumed to be the legal father of children born during the marriage — an unmarried father must take affirmative legal steps to establish paternity before any custody or parenting time rights attach.
If you were not married to the mother when your child was born, the mother has sole legal and physical custody by default under Michigan law. You have no right to parenting time, no right to be consulted on major decisions, and no legal standing to prevent the mother from moving with the child — until you establish paternity and obtain a court order.
This is not a small gap. It means the mother can move across Michigan or potentially out of state, change the child's school, make medical decisions, and structure the child's life entirely without your input. Every day without legal standing is a day that schedule becomes more entrenched.
Paternity can be established two ways in Michigan:
Affidavit of Parentage (AOP). If both parents agree you are the father, both parents can sign an Affidavit of Parentage — typically at the hospital at the time of birth, or later at a local health department or vital records office. Once signed and filed with the Michigan Department of Health and Human Services, you are the child's legal father.
Important: signing the AOP establishes paternity but does not give you custody or parenting time. It only creates the legal foundation to petition for those rights.
Court-ordered paternity action. If the mother disputes paternity or refuses to sign the AOP, you can file a paternity action in circuit court. The court can order DNA testing. Once paternity is established by court order, you have standing to seek custody and parenting time.
Once paternity is established, you petition the circuit court for custody and parenting time. The same 12 best-interest factors under MCL 722.23 apply to unmarried father cases as to married parents' cases. There is no presumption against you based on your marital status — only on the evidence.
What courts do consider for unmarried fathers: your involvement since the child's birth, whether you've provided financial support, whether you've been present and active in the child's daily life, and your stability and capacity to provide care.
The longer you wait, the harder your case becomes. Courts are reluctant to dramatically disrupt a child's established life. If the child has been in the mother's home for two years without you having a formal parenting role, you will face a harder burden than a father who filed within the first few months. The moment your child is born — or the moment you learn you may be the father — is the time to act.
