What Paternity Means in Nassau County, NY

In New York, a child born to unmarried parents does not have a legal father until paternity is established. The legal father is the man who has either signed an acknowledgment of paternity, been found to be the father by a court order, or who later marries the child’s mother and a legal acknowledgment is completed. Without that legal finding, the presumed genetic father has no enforceable rights to custody or visitation, and no obligation to pay child support. Paternity creates the legal framework that governs everything from decision-making authority to inheritance rights.

In Nassau County, paternity petitions are filed in the Family Court, which sits in Mineola. The court may order genetic testing and, where the results establish a probability of paternity at or above the threshold set by statute, an order of filiation is entered. Once filiation is ordered, the court can proceed to determine custody, visitation, and child support. Because the same court has jurisdiction over these related matters, the paternity proceeding often becomes the starting point for a broader family law resolution. Mr. Sris and the firm’s Of Counsel attorneys represent clients in these proceedings, addressing the legal and practical questions that arise from the outset.

How Mr. Sris and the Firm’s Of Counsel Attorneys Handle Paternity Cases

A paternity case often arrives during a period of considerable uncertainty. The firm begins by identifying what each client needs: a parent seeking to establish a legal relationship with a child, a parent looking to secure support, or a person who disputes an allegation of paternity. The legal strategy is tailored to that goal. In cases where an acknowledgment of paternity is appropriate, counsel can help ensure the document meets New York requirements and does not waive rights inadvertently. When genetic testing is necessary, the firm guides the client through the court-ordered process and reviews the results with the specific statutory standard in mind.

If a hearing is required, preparation includes gathering documentary evidence, preparing witness testimony where appropriate, and presenting the matter before the Family Court judge. Mr. Sris and the firm’s Of Counsel attorneys appear regularly in Nassau County Family Court and understand the local procedural expectations. The objective is to resolve the paternity question efficiently, allowing the parties to move on to the issues that ultimately matter: custody arrangements, parenting time, and financial support for the child.

Frequently Asked Questions

What is the legal effect of establishing paternity in New York?

Establishing paternity gives a child a legal father, creating rights to inheritance, health insurance coverage, and financial support, and also gives the father the right to seek custody and visitation. In New York, paternity may be established by an acknowledgment signed by both parents, by a court order after a petition and genetic testing, or by a later marriage of the parents. The court’s order of filiation is the document that formally identifies the legal father and triggers the father’s obligations and rights under the Family Court Act.

Do I need a lawyer to file a paternity petition in Nassau County?

You are not required by law to hire an attorney to file a paternity petition, but having legal counsel helps ensure that the petition is properly prepared, that your rights are protected, and that you understand the consequences of the proceeding. An attorney can advise you on whether an acknowledgment of paternity is appropriate, represent you at genetic testing proceedings, and argue for or against a finding of paternity based on the evidence. Contact Law Offices Of SRIS, P.C. at (888) 437-7747 to schedule a consultation.

How does the court decide paternity when the alleged father denies it?

The court will typically order genetic testing when paternity is disputed; the results are the primary evidence and if they indicate a high probability of paternity, the court will enter an order of filiation. New York law sets a statutory threshold for the probability of paternity shown by genetic testing. If the test meets that threshold, the court will declare legal paternity. If the alleged father continues to contest, a hearing may be held, but the genetic test results carry significant weight.

Can paternity be established if the father lives outside New York?

Yes, a paternity petition can be filed in Nassau County if the child or the mother resides in the county, even if the alleged father lives in another state. The court may need to arrange for service of process on the out-of-state father, and if he fails to appear or respond, the court may proceed by default. Mr. Sris and the firm’s Of Counsel attorneys can explain how jurisdictional rules apply in your particular circumstances.

What happens to child support after paternity is established?

Once paternity is legally established, the court can order the father to pay child support under the New York Child Support Standards Act, which calculates support as a percentage of the parents’ combined income. The court will also address retroactive support to the date of the child’s birth or the filing of the petition. The order is enforceable through income withholding and other collection mechanisms. The same court that establishes paternity has authority to set the support amount.

How long does a paternity case take in Nassau County Family Court?

The timeline varies depending on whether the parties agree to an acknowledgment of paternity, whether genetic testing is ordered, and the court’s calendar. If all parties cooperate and paternity is voluntarily acknowledged, the matter can be resolved without a protracted proceeding. When genetic testing is required, the process may take additional weeks. For a more specific estimate based on your situation, reach Law Offices Of SRIS, P.C. at (888) 437-7747.
