Can a Mother Refuse a Paternity Test in Ohio?

 Posted on April 30, 2026 in Family Law

A mother can refuse a voluntary paternity test, but she cannot refuse one that has been ordered by a court. In Ohio, if a man files a legal action to establish or challenge paternity, a judge has the authority to order genetic testing regardless of whether the mother agrees. Refusing a court-ordered paternity test carries serious legal consequences. If you are dealing with a paternity dispute in 2026, our Wadsworth, OH paternity lawyers can help you understand your rights and what steps to take next.

How Is Paternity Established in Ohio?

In Ohio, paternity can be established in two main ways. The first is voluntary, through a document called an Acknowledgment of Paternity Affidavit. This is a form that both parents sign, usually at the hospital after the birth, that legally recognizes a man as the child's father. No DNA test is required for this process. Once properly filed, it can become final and enforceable without a court order.

The second way is through the court system. Under Ohio Revised Code § 3111.01, either parent, the child, or certain government agencies can file a court action to establish paternity. Once a case is filed, the court can order genetic testing to determine biological parentage.

What Happens if a Mother Refuses a Court-Ordered Paternity Test in Ohio?

If a court orders genetic testing and the mother refuses to comply, she can be found in contempt of court. That can result in fines, sanctions, or other penalties the judge decides are appropriate. In some cases, a court may draw a negative inference from the refusal, meaning the judge can consider the refusal itself as evidence when making decisions about paternity. Refusing a court order does not make the issue go away. It typically makes the situation more complicated for the person who refuses.

Can a Father Force a Paternity Test in Ohio?

A man who believes he is the biological father of a child, or a man who has been named as a father but doubts it, can file a complaint to establish or challenge paternity in the Ohio court system. Once the case is filed, the court has authority under Ohio Revised Code § 3111.09 to order genetic testing of the mother, the child, and the alleged father. Neither the mother nor any other party can block a court-ordered test once it has been properly requested through the legal process.

What Rights Does Establishing Paternity Give a Father in Ohio?

Establishing paternity is about more than just biology. Once paternity is legally established, the father gains legal rights, including the right to seek custody or visitation. He also takes on legal responsibilities, most notably the obligation to pay child support. A father who is not legally recognized has no right to be involved in the child's life, and the child has no legal claim to financial support from him.

For the child, established paternity opens the door to important benefits, including inheritance rights, access to the father's health insurance, eligibility for Social Security benefits based on the father's record, and the right to know their full medical history.

What if a Man Wants To Challenge Paternity He Already Acknowledged in Ohio?

Once an Acknowledgment of Paternity is signed, there is a limited window to rescind it without going to court. Under Ohio Revised Code § 3111.27, a signed acknowledgment can be rescinded within 60 days of signing or before a court issues an order based on the acknowledgment, whichever comes first. After that window closes, challenging paternity requires going to court and showing a specific legal reason to set aside the acknowledgment, such as fraud, duress, or a material mistake of fact.

Courts in Ohio take signed acknowledgments seriously, and setting one aside after the deadline is not easy. Acting quickly if you have doubts is important.

Can a Mother Refuse a Paternity Test When the Child Support Agency Is Involved?

If the Ohio Department of Job and Family Services or a child support enforcement agency is involved in the case, the rules are similar. These agencies can initiate paternity proceedings, and a court can order testing as part of that process. A mother who refuses testing in this context faces the same contempt consequences as in any other court-ordered situation.

Ohio courts prioritize the best interests of the child in all paternity proceedings. That means the focus is always on establishing the truth and making sure the child has the support and relationships they are entitled to.

What Should You Do if You Are Involved in a Paternity Dispute in Ohio?

Whether you are a mother facing a paternity action, a man seeking to establish your rights, or someone who has doubts about a prior acknowledgment, getting legal help early makes a real difference. Paternity cases can move quickly once they are filed, and missing a deadline or making a misstep early in the process can affect your rights significantly.

Do not sign an Acknowledgment of Paternity if you have any doubts about it. Do not ignore a court filing related to paternity. And do not assume that refusing to participate will make the situation go away. It will not.
