Paternity Attorney in Manhattan, New York
Establishing legal parentage is one of the most fundamental acts in family law — and one with lifelong consequences for parents and children alike. For fathers seeking recognition of their parental rights, mothers seeking child support from a biological father, or individuals navigating complex parentage questions, Steven J. Mandel at Warshaw Burstein, LLP, provides skilled, compassionate paternity representation throughout Manhattan and New York City.
Why Paternity Matters
Legal paternity is not simply a biological fact — it is a legal status that carries profound rights and obligations. For children, legal paternity means the right to financial support, inheritance rights, access to the father’s medical history, and eligibility for Social Security, veterans, and other benefits. For fathers, it means the right to seek custody and visitation and to be a legal presence in their child’s life. For mothers, establishing paternity is often the essential first step to obtaining court-ordered child support.
How Paternity Is Established in New York
New York provides three pathways to legal paternity:
- Voluntary Acknowledgment of Paternity — both parents sign a form at the hospital or later, creating legal paternity without court involvement
- Administrative Establishment — through the Child Support Enforcement Unit, typically in connection with public assistance cases
- Judicial Establishment — through a Family Court paternity proceeding, typically involving DNA testing
In contested cases — where paternity is disputed — the Family Court will order genetic testing. Modern DNA testing is conclusive in excluding a man as the biological father and highly probative in establishing biological paternity.
Contesting Paternity in Manhattan
Not every paternity claim is correct. A man who is incorrectly named as a father — whether on a birth certificate, in a support proceeding, or through an acknowledgment signed under pressure or misunderstanding — has legal options to challenge paternity in New York. These challenges are time-sensitive and fact-specific. The court must balance the legal arguments against the best interests of the child, particularly where a father-child relationship has already formed.
Paternity and Custody Rights
Establishing paternity is the gateway to custody rights for unmarried fathers. Without legal paternity, a father has no enforceable right to custody or visitation — even if he has been actively involved in the child’s life. Once paternity is established, an unmarried father can petition for custody or visitation on the same legal footing as any other legal parent.

Frequently Asked Questions: Paternity Attorney in Manhattan
Q1: How is paternity established in New York?
Paternity in New York can be established in three ways: voluntarily, by both parents signing an Acknowledgment of Paternity form (typically at the hospital after birth); administratively, through the Child Support Enforcement Unit; or judicially, through a paternity proceeding in Family Court where DNA testing is typically ordered. Once paternity is legally established, the father has the same legal rights and obligations as any other legal parent.
Q2: Can I request a DNA test to establish or contest paternity in New York?
Yes. Either party in a New York paternity proceeding can request genetic (DNA) testing, and courts routinely order it. DNA testing is highly accurate and is the standard method for resolving contested paternity cases. If a man is conclusively excluded as the biological father through DNA testing, he will not be found to be the legal father. Conversely, a match establishes biological paternity, which the court then translates into legal paternity.
Q3: What are the legal consequences of establishing paternity in New York?
Establishing paternity creates full legal parentage — including the right to seek custody and visitation, the obligation to pay child support, the child’s right to inherit from the father, the child’s right to Social Security and veterans’ benefits through the father, and access to the father’s medical history. For both fathers and children, establishing legal paternity is foundational to a complete legal parent-child relationship.
Q4: Can paternity be established after a child is born in New York?
Yes — paternity can be established at any time during a child’s minority (under 18), and in some circumstances beyond. There is no strict statute of limitations for paternity proceedings in New York, though promptness is advisable when custody, support, or inheritance rights are at stake. Genetic material can also be used to establish paternity posthumously in estate and inheritance cases.
Q5: What if I am listed on the birth certificate but am not the biological father?
Being listed on a birth certificate creates a presumption of legal paternity in New York, but it can be challenged. If you were listed on a birth certificate without your consent, or if you later discovered you are not the biological father, you may be able to file a petition to vacate the acknowledgment of paternity or to contest legal parentage through DNA testing. Time limits apply, and the court will consider the best interests of the child as well as the equities of the situation.
