Nassau County Parentage Lawyer — How Do You Establish Paternity?
Establishing parentage (paternity) in Nassau County, New York, is a legal process to determine a child’s legal father under the New York Family Court Act. This action is foundational for securing child support, custody, and visitation rights. Law Offices Of SRIS, P.C. provides experienced legal guidance for parentage matters in Nassau County Family Court.
What Is Parentage Law in New York?
Parentage, often called paternity, refers to the legal establishment of a father-child relationship. In New York, this is governed primarily by the Family Court Act (FCA) and the Domestic Relations Law (DRL). When parents are not married at the time of a child’s birth, the biological father has no automatic legal rights or responsibilities. A parentage proceeding formally establishes this legal link, which is necessary for the court to issue orders for child support, custody, and visitation. The legal standard is the “best interests of the child,” and establishing parentage provides the child with access to benefits like inheritance, social security, and health insurance.

Nassau County Parentage Procedures and Strategic Insights
Parentage cases in Nassau County Family Court follow a specific procedural path. The process can be initiated by either parent, a child’s guardian, or a social services agency. A key local procedural fact is that Nassau County Family Court handles all paternity, custody, and support matters arising from parentage cases, while the Supreme Court handles divorce-related parentage issues. The court strongly encourages voluntary Acknowledgment of Paternity, which can be signed at the hospital or later. If paternity is disputed, the court will order genetic (DNA) testing, which is highly accurate.
- File a Petition: The process begins by filing a “Petition to Establish Paternity” (Form P-1) with the Nassau County Family Court Clerk’s office. There is a filing fee, though fee waivers are available based on income.
- Serve the Other Party: The petition and a summons must be formally served on the other alleged parent, giving them notice of the proceeding and their right to respond.
- Genetic Testing (If Disputed): If the alleged father denies paternity, the court will order genetic marker testing. All parties and the child must submit to testing at an approved facility.
- Court Hearing & Order: Based on the test results or an admission, the court will issue an “Order of Filiation” legally establishing paternity. This order is necessary before the court can issue child support or custody/visitation orders.
- Establish Support & Custody: Once paternity is established, separate petitions for child support (Form 4-1) and/or custody/visitation (Form 6-1) can be filed and adjudicated.
Consequences and Outcomes of Establishing Parentage
In Nassau County, establishing parentage creates legal rights and duties, including child support obligations based on statutory guidelines and custody/visitation arrangements determined by the child’s best interests.

Frequently Asked Questions: Parentage in Nassau County
How is paternity established in New York if the father is not listed on the birth certificate?
Yes. Paternity can be established voluntarily by both parents signing an Acknowledgment of Paternity form. If disputed, either parent can file a petition in Family Court to seek a court order for genetic testing and an Order of Filiation.
Can a father get custody rights through a parentage case?
Yes. Once paternity is legally established via an Order of Filiation, the father has the right to file a petition for custody or visitation. The court will decide based on the child’s best interests, considering factors like the child’s relationship with each parent, parental fitness, and stability.
How far back can child support be ordered in a New York paternity case?
It depends. New York law allows the court to order retroactive child support back to the child’s date of birth, regardless of when the petition was filed. The specific amount is discretionary and based on the father’s income during that period and the child’s needs.
What is the difference between Nassau County Family Court and Supreme Court for parentage?
Nassau County Family Court handles standalone paternity, custody, and support cases. The Supreme Court handles parentage issues that are part of a divorce or annulment proceeding. The legal standards are the same, but the procedural paths differ.
Is DNA testing always required?
No. DNA testing is only required if paternity is disputed. If both parents agree and sign a voluntary Acknowledgment of Paternity, that document has the full force of a court order and testing is unnecessary.
