When a child is born to married parents, the law assumes the husband is the biological father. But for unmarried parents, legal paternity must be formally established—regardless of the father’s involvement or the couple’s relationship status.
Establishing paternity is crucial for both the child and the parents. It affects everything from the child’s birth certificate and legal name to their right to inherit, receive child support, or access health and life insurance. It also gives fathers legal rights to custody and visitation.
So how exactly is paternity established? What happens if the father didn’t sign the birth certificate? And what can mothers—or fathers—do if there’s a dispute?
Let’s break it down.

Why Establishing Paternity Matters
Paternity refers to the legal recognition of a man as the child’s father. Without it, an unmarried father has no legal rights or responsibilities regarding the child—even if he is biologically related.
Here’s why it matters:
- For the child: They gain access to financial support, health insurance, Social Security or veteran’s benefits, inheritance rights, and medical history from both sides of the family.
- For the mother: Legal paternity allows her to seek child support or share decision-making responsibilities with the father.
- For the father: It provides legal standing to request custody, parenting time, and a role in the child’s upbringing.
Without legal paternity, a father may find himself with no say in the child’s life, and a mother may be left without support.
Common Parentage Issues for Unmarried Parents
Many legal and practical issues can arise when parents are not married at the time of a child’s birth. These include:
🔹 The Father Isn’t Listed on the Birth Certificate
If the father is not present or doesn’t sign the necessary paperwork at the hospital, he may not be listed on the child’s birth certificate. This omission can have serious legal consequences.
🔹 The Father Disputes Paternity
In some cases, the man identified as the father may deny he is biologically related to the child. Or another man may claim to be the father.
🔹 The Mother Refuses to Name the Father
Sometimes, the mother may not want to list the father—due to personal, legal, or safety concerns.
In all of these situations, paternity must be resolved legally in order to move forward with custody, support, or parental rights.
How to Establish Paternity
In most states, including New York, there are two main ways to establish paternity outside of marriage:
- Voluntary Acknowledgment of Paternity (AOP)
If both parents agree on who the father is, they can sign an Acknowledgment of Paternity form. This is often done at the hospital after birth but can also be completed later at a child support office or local vital records agency.
Once filed, the AOP has the same legal effect as a court order.
Key points:
- Both parents must sign voluntarily
- Either parent can rescind within a limited time frame (usually 60 days)
- This form is only valid if there’s no doubt about paternity
Once filed, the father’s name can be added to the birth certificate, and the child may take his last name if agreed upon.
- Court-Ordered Paternity (Petition for Parentage)
If there’s disagreement or uncertainty, either parent can file a petition in family court to establish paternity. The court may order:
- DNA testing (cheek swab from the child, mother, and alleged father)
- Temporary child support or visitation arrangements
- A final legal judgment confirming paternity
Once the court issues a paternity order, it provides the legal foundation for child support, custody, visitation, and name changes.
What If the Father Didn’t Sign the Birth Certificate?
If the father did not sign the birth certificate or the acknowledgment form at birth, don’t panic—paternity can still be established later.
Options include:
- Asking him to sign a Voluntary Acknowledgment now
- Filing a petition in family court to request a DNA test
- Involving the Child Support Enforcement Office, which can help track down and test the alleged father
Until paternity is established, the biological father has no legal rights or responsibilities. That’s why it’s important for both parents to formalize their legal relationship to the child, even if they are amicably co-parenting.
Naming the Child: What Are the Rules?
In most states, including New York:
- The mother has the initial right to name the child at birth
- If both parents sign a voluntary acknowledgment of paternity, they can agree on the child’s last name
- If paternity is established later through the courts, either parent can petition to change the child’s last name
However, when disputes arise over the child’s name—particularly after paternity is legally established—the matter may need to be resolved in family court. Judges will make decisions based on the best interests of the child, considering factors such as cultural significance, family heritage, and the child’s sense of identity.

Final Thoughts: Parenthood Is More Than Biology
Establishing paternity is about legal clarity, family security, and shared responsibility. While it may seem like just a formality, it carries real consequences for everyone involved—especially the child.

Because when paternity is established the right way, everyone wins—especially the child.
