Michigan Stepparent Adoption Guide 2026: Complete Process

The short answer: Michigan lets a stepparent adopt without the other parent's consent when, for two years or more before the petition is filed, that parent has failed to provide regular and substantial support and has regularly and substantially failed to visit, contact or communicate with the child, when able to (MCL 710.51(6)). That's the real world in Michigan courts: the father never signs a consent, and the judge approves the adoption anyway. In our experience, about 80% of the stepparent adoptions we've completed went forward without the other biological parent's consent.

Michigan Stepparent Adoption: What You Need to Know in 2026

Michigan's adoption rules are in its adoption code, MCL 710.21 and following. Adoptions are heard by the family division of the circuit court (MCL 710.22(m)). If you've been raising your stepchild as your own, the law has a clear path for making it official, including when the other parent is no longer in the picture.

What Is Stepparent Adoption in Michigan?

It's the court process that makes you your stepchild's legal parent: medical decisions, school authority, inheritance and lifelong family ties. Your spouse keeps all of their rights. The other parent's rights and responsibilities end, including the duty to pay child support going forward (Child Welfare Information Gateway). Whether any back support already owed can still be collected depends on Michigan law and the facts of your case.

You can also ask to give your child your family name, or adopt without a name change; Michigan's petition statute covers both (MCL 710.24(1)).

Does the Other Parent Have to Consent?

Not in most cases. Michigan's stepparent rule, MCL 710.51(6), applies when the child's parents are divorced, or were unmarried but the father acknowledged paternity or is a putative father who meets the statute's conditions, and the parent with custody under a court order has married the stepparent who is petitioning. The court, after notice and a hearing, can end the other parent's rights when both of these are true:

1. Support: having the ability to support or help support the child, he failed or neglected to provide regular and substantial support, or, if there's a support order, failed to substantially comply with it, for two years or more before the petition was filed. A support order of $0.00 or one that reserves support is treated as if there were no order.
2. Contact: having the ability to visit, contact or communicate with the child, he regularly and substantially failed or neglected to do so for two years or more before the petition was filed.

This is the most common situation we see in Michigan: a parent who simply dropped out of the child's life, with no regular visits, calls or support for years.

If paternity was never legally established, different Michigan rules for a putative father apply. If the other parent has passed away, his consent isn't needed and you include the death certificate.

What If the Other Parent's Whereabouts Are Unknown?

An unknown address doesn't stop the adoption. Make a reasonable search (last known addresses, relatives, social media, public records) and keep a written record. When a parent can't be found, the court can allow notice by publication in a newspaper. If he doesn't respond, the case moves forward. In our experience, Michigan courts handle these cases routinely.

What If the Other Parent Is Willing to Consent?

That works too. In Michigan, a consent to adoption must be a separate document signed before the judge with jurisdiction, another family division judge in Michigan at the court's direction, or a juvenile court referee. A parent in the armed services or in prison may sign before anyone authorized to administer oaths, and a consent signed in another state is checked against that state's law (MCL 710.44).

Step 1: Confirm Eligibility

You're married to the child's parent, and that parent has custody of the child. Write down the other parent's two-year history of support and contact, with dates.

Step 2: Determine the Consent Situation

Compare his history with both parts of MCL 710.51(6). If he's met both for two years or more, you can proceed without his consent. If he's willing to sign, plan for a consent before a judge or referee.

Step 3: Prepare and File the Petition

File with the court of the county where you live, where the child is found, or where the other parent's rights were terminated or are pending termination (MCL 710.24(1)). Your packet typically includes:

Step 4: Serve the Other Parent

The other parent gets notice of the hearing on termination, either directly or, if he can't be found, by publication as the court allows.

Step 5: The Court's Investigation

After filing, Michigan law calls for an investigation by an employee or agent of the court, a child placing agency, or the state department (MCL 710.46). In a stepparent case, the investigator is looking at a household the child already lives in. Ask your clerk how your county schedules it and whether there's a fee.

Step 6: Attend the Adoption Hearing

The judge confirms the requirements are met and that the adoption serves your child's best interests. Michigan lists the factors, including the emotional ties between you and the child, the stability of the home, and the child's reasonable preference when the child is old enough to express one (MCL 710.22(g)). For most stepfamilies, the answers are obvious, and the hearing is short and happy.

Step 7: Obtain the New Birth Certificate

After the order is entered, request a new birth certificate from the vital records office in the state where your child was born. It lists you as a parent and shows the new name if one was ordered. Then update Social Security (Form SS-5 if the name changed), school, medical and insurance records.

Second Parent Adoption in Michigan: What About Unmarried Couples?

Michigan's stepparent rule in MCL 710.51(6) is written for the spouse of the custodial parent. If you aren't married to your partner, check the Michigan guide and talk with a Michigan family law attorney before filing. For many couples, marrying first and then filing a stepparent adoption is the clearest path.

How Long Does It Take?

Many uncontested adoptions finish within a few months. In Michigan, the court calendar, the investigation and any publication period set the pace. If the other parent actively fights the termination, talk with a Michigan family law attorney.

Frequently Asked Questions

Can I adopt my stepchild in Michigan if the other parent hasn't been around for years?

Yes. If, for two years or more before filing, he failed to provide regular and substantial support and regularly and substantially failed to visit or contact the child, when able to, the court can end his rights without his consent (MCL 710.51(6)). The father never signs a consent, and the judge approves the adoption anyway.

Do both the support and the contact parts have to be met?

Yes. Michigan's statute requires both. A $0 support order, or one that reserves support, is treated as if no order had been entered.

Can I adopt if I don't know where the other parent is?

Yes. After a reasonable search, the court can allow notice by publication. If he doesn't respond, the case moves forward.

Does Michigan require a home study for stepparent adoption?

Michigan law calls for an investigation after the petition is filed (MCL 710.46). In a stepparent case it looks at the home your child already lives in.

Does my stepchild need to consent?

Yes, if your child is over 14 (MCL 710.43(2)).

Can my stepchild take my last name?

Yes, if you ask. Michigan's petition statute covers adopting with or without a name change (MCL 710.24(1)), and the new name appears on the order and the new birth certificate.
