How paternity affects child support and benefits in Michigan

On Behalf of | Sep 30, 2026 | Child Support |

Your child’s future can feel uncertain when you and the other parent are not married. Establishing paternity may address concerns about support, health coverage and long-term protection.

Biological and legal fatherhood

Michigan law treats a biological father and a legal father differently. Unmarried parents must take extra steps to create a legal relationship.

Without those steps, a father may lack standing to seek custody or parenting time. A mother may also lack a way to enforce support. The Paternity Act sets out a court process that ends with an order of filiation.

Two ways to establish paternity

Michigan law offers more than one way to create a legal parent-child relationship. Unmarried parents in Livonia generally have two options: 

  • Affidavit of Parentage: Both parents sign a notarized form and file it with State Vital Records.
  • Court action: Either parent can file in Wayne County Circuit Court. The court may order DNA testing.

Parents who agree often choose the affidavit. A court action may fit better when they disagree.

How paternity connects to child support

Child support usually depends on legal parentage. Once paternity is established, either parent may ask the Friend of the Court to open a support case.

Michigan uses a formula that may weigh both parents’ incomes, overnights and childcare costs. Enforcement tools might include paycheck withholding and tax refund interception.

Benefits beyond monthly support

Legal parentage may open other protections for your child. These could include:

  • Health insurance: A parent may enroll the child in an employer plan.
  • Survivor benefits: The child may qualify for Social Security or veterans’ benefits if a parent dies.
  • Inheritance: A child may have a stronger claim to a parent’s estate without a will.
  • Medical history: Doctors can use family health records to spot hereditary risks.

These protections can matter most during a crisis. Eligibility rules vary by program.

Protecting your child’s long-term stability

Paternity can shape support, benefits, inheritance and medical care for your child. You can establish it by affidavit or through the court. This matters because these protections may last well into adulthood.

Paternity can also affect custody and support issues in your case. If your situation becomes more complicated, an attorney can help you understand your options.
