What Is the Statute of Limitations To Challenge Paternity?
By John Devendorf, Esq. | Reviewed by Canaan Suitt, J.D. | Last updated on October 21, 2025Challenging paternity involves court proceedings to dispute or establish parental rights and obligations. Either parent or the child can file an action in family law court to establish or challenge paternity. However, most states have a time limit for bringing a paternity claim. For most states, you can challenge paternity until the child reaches age 18.
The statute of limitations for challenging paternity varies by state and can depend on various factors. If you have questions about establishing who is the biological father of the child, talk to a fathers’ rights lawyer for legal advice.
Understanding Paternity Challenges
In most cases, maternity is not in question. Unless there is an adoption or surrogacy, the person who gives birth to the child is the legal and biological mother. The legal father of the child is not as clear. When parents dispute who the father of the child is, the court can establish it.
In paternity disputes, genetic testing can identify the biological father. DNA test results show whether the presumed father shares genetic markers to prove the paternity of a child.
When a father is presumed to be the biological father, the father can seek a court order to disestablish paternity. Disestablishing paternity takes away the legal rights and obligations of fatherhood. If the court finds fatherhood based on a paternity test, you cannot disestablish paternity. However, you can terminate your parental rights, which is a separate process.
Establishing Paternity
There are generally a few ways to establish paternity for a minor child, including:
- Presumption of paternity for married parents
- Affidavit of parentage or voluntary acknowledgment of paternity
- Court order establishing the legal father
Most states have a presumption that when a married mother gives birth to a child, the marital partner is the father. The paternal presumption can even apply to divorced couples when the birth happened within a certain amount of time from the date of divorce. For a married mother to designate someone other than their partner as the father, they may need to establish paternity.
A father can also establish the presumption of paternity by signing the birth certificate. The parents who sign the child’s birth certificate are generally the legal parents. Parents can affirmatively acknowledge paternity after the child’s birth. Unmarried parents can have the father sign an affidavit acknowledging paternity.
If either parent disputes paternity or the putative father does not want to acknowledge paternity, the mother can seek a court order to establish paternity. The court can require a blood test in paternity cases to establish biological and legal parentage.
Statute of Limitations for Challenging Paternity
The statute of limitations is the time limit to bring a legal action. States have statutes of limitations for various types of legal claims, including challenging paternity.
The statute of limitations for challenging paternity is generally based on when the child reaches a certain age or the age of majority. If you file a paternity case after the statute of limitations passes, you will lose out on your legal rights to challenge paternity. The court can dismiss your case for falling outside the deadline.
The court may make exceptions to give a child or parent more time to establish paternity. Exceptions can include fraud, material mistake of fact, or avoiding legal service. The time limit can also depend on whether someone is already a presumed father or if fatherhood was never established.
State-By-State Statute of Limitations for Challenging Paternity
The statute of limitations for a paternity action depends on state law. Each state has a different statute of limitations for challenging the determination of paternity.
The following is an overview of the time limit for challenging paternity by state. Never assume the statute of limitations has passed because the court can make exceptions based on the child’s best interests. Talk to an experienced fathers’ rights attorney to understand the statute of limitations to challenge paternity in your situation.
Legal Process for Challenging Paternity
If the parents do not voluntarily acknowledge paternity, either parent can file a case with the family court or juvenile court where the child lives. The family court or child support services can issue a proposed order to establish paternity and child support. After court service, the mother or alleged father can request genetic testing.
If DNA genetic testing establishes the alleged father is the biological parent, the court establishes paternity. If the alleged father is not the biological father of a child, the court can enter an order of non-paternity. The court can also determine who will pay the costs of genetic testing reimbursement, court fees, and legal costs.
In some states, ignoring the court order or failing to respond to establishing parentage can mean the state establishes legal paternity. The putative father will have to take court action to disestablish paternity.
Implications for Child Support
Establishing paternity has important implications for child support obligations. The legal father must pay for the support of the child until the child becomes an adult. In some states, parents must legally support the child even after adulthood if the child is attending higher education or vocational training.
The family court may require the legal father to provide child support to the custodial mother. If the father does not pay, the court can withhold their income and take other child support enforcement actions.
By establishing paternity, the custodial parent can claim back child support for caring for the child. However, state laws limit how far back a parent can collect retroactive child support. In most states, a parent can only collect child support retroactively going back one to two years.
Once the court establishes a parent-child relationship, the court can enforce child support orders to collect on unpaid child support. Enforcement actions include wage garnishment, a suspended driver’s license, and possible jail time.
Potential Outcomes of Paternity Challenges
Paternity is important because it establishes the legal rights and obligations of the parents. The legal father must provide financial support for the child throughout the child’s life. They also have parenting rights to determine how to raise the child, including education, childcare, and religious upbringing. The legal father has child custody and visitation rights.
