Learn how paternity is established in Maryland — through voluntary acknowledgment or court order — and what rights and responsibilities follow for fathers, mothers, and children.

Paternity — legal fatherhood — is one of the foundational issues in family law for children born outside of marriage. Establishing paternity unlocks critical rights for children and carries significant legal responsibilities for fathers. Maryland law provides clear pathways for establishing, and sometimes challenging, legal fatherhood.
Why Paternity Matters in Maryland
For children, establishing paternity means:
- The right to financial support from both parents
- Access to the father's health insurance and benefits
- Eligibility for Social Security, veterans', and inheritance rights
- A complete medical history from both sides of the family
- The emotional and developmental benefits of knowing both parents For fathers, establishing paternity creates the legal right to seek custody and parenting time — rights that do not exist for unmarried fathers until paternity is legally established.
For mothers, establishing paternity enables enforcement of child support obligations against the child's father.
How Paternity Is Established in Maryland
Maryland law provides two primary methods for establishing paternity, as administered by the Maryland Department of Human Services Child Support Services:
- Voluntary acknowledgment through an Affidavit of Parentage
- Court order following a paternity proceeding If both parents are married at the time of the child's birth, the husband is presumed to be the legal father — no additional action is required to establish paternity.
Voluntary Acknowledgment: The Affidavit of Parentage
The simplest way to establish paternity when both parents agree is through an Affidavit of Parentage — a voluntary written declaration signed by both parents acknowledging that a specific man is the child's father. This form is typically offered to parents at the hospital at the time of birth.
Once signed, the Affidavit of Parentage has the same legal effect as a court order establishing paternity. The father's name is added to the child's birth certificate.
Important: The Affidavit of Parentage can be rescinded within 60 days of signing. After that window, it can only be challenged in court on grounds of fraud, duress, or material mistake of fact.
Establishing Paternity Through the Courts
When parents disagree about paternity — or when the mother seeks child support from an unwilling or absent father — paternity must be established through a court proceeding.
Either parent, or the Office of Child Support Enforcement, can file a petition to establish paternity in the appropriate court. Under Maryland Code, Family Law § 5-1002 et seq., the court can:
- Order genetic testing of the child, the mother, and the alleged father
- Establish paternity based on genetic testing results
- In some circumstances, establish paternity based on a father's sworn admission without genetic testing Maryland courts have recognized that if a putative father admits under oath that he is the child's father during a legal proceeding — without objection from the mother — the court can establish paternity based on that admission alone.
Genetic Testing in Maryland Paternity Cases
If the issue of paternity is uncertain or disputed, either parent can request genetic testing. Maryland courts routinely order DNA testing when paternity is at issue. Modern DNA testing is highly accurate — excluding or establishing paternity with a probability exceeding 99%.
The alleged father cannot refuse court-ordered genetic testing. If he refuses to comply, the court may draw an adverse inference from the refusal.
Rights and Responsibilities After Paternity Is Established
Once paternity is legally established: For the father:
- The right to petition for custody or visitation
- The legal obligation to pay child support
- The duty to provide health insurance if available at a reasonable cost For the child:
- The right to child support from both parents
- The right to inherit from the father
- Access to the father's Social Security, military, and other benefits Paternity alone does not automatically create custody rights for the father — he must separately petition the court for custody or visitation. Disestablishing Paternity in Maryland In limited circumstances, a man who has been legally established as a child's father may seek to challenge that designation — a process sometimes called "disestablishing paternity." This is extremely difficult and courts are reluctant to do it, especially when the father has acted as the child's parent for a significant period of time. Grounds for challenging established paternity include fraud, duress, or material mistake of fact. Courts will consider the impact on the child, including emotional harm from having a legal father relationship severed.

FAQ
Does an unmarried father have rights in Maryland before paternity is established?
No. An unmarried father has no legal rights to custody or visitation until paternity is legally established — either through an Affidavit of Parentage or a court order.
What if the alleged father denies he is the father?
Either parent or the Child Support Administration can petition the court for a paternity determination. The court will typically order genetic testing to resolve the issue.
Can paternity be established after the child turns 18?
Maryland generally allows paternity actions while the child is a minor. Once a child reaches adulthood, the window for establishing paternity for purposes of child support may be limited.
Does establishing paternity affect immigration status?
In some circumstances, yes. Establishing paternity can affect a child's citizenship or immigration status if the father is a U.S. citizen or has a particular immigration status. An immigration attorney should be consulted in such cases.
Is a DNA test required to establish paternity in Maryland?
Not always. Paternity can be established voluntarily through the Affidavit of Parentage or through a judicial admission. DNA testing is ordered when paternity is disputed or uncertain. Paternity matters for everyone involved — especially the child. If you need to establish or challenge paternity in Maryland, consult a family law attorney to understand your rights and navigate the process correctly.
