New Jersey Paternity Lawyer

An unmarried father who wants a legal place in his child’s life, or a mother who needs financial support from a parent who has not acknowledged the child, cannot rely on biology alone to settle either question. At Sanvenero & Cittadino, LLC, our family law attorneys handle paternity and parentage matters for parents throughout Monmouth County, Ocean County, and Middlesex County, along with the rest of New Jersey. If you are searching for a New Jersey paternity lawyer, the work usually begins with one question: has legal parentage been established, and if not, how do you establish it?

Paternity is the gateway to nearly everything else in a case involving unmarried parents. Until a father’s legal status is established, whether by a signed acknowledgment or a court order, he generally has no enforceable right to parenting time or a voice in custody decisions, and the child’s other parent has no enforceable claim against him for child support. Once paternity is settled, the Family Part of the Superior Court can address custody, parenting time, child support, medical coverage, and the allocation of child-related expenses in the same way it would for a divorcing couple. Many families we meet have lived for years with an informal arrangement that worked until it did not, and the first job is turning that arrangement into something a court can enforce.

Paternity cases look simple on paper and often are not. A father may have signed an acknowledgment at the hospital without understanding what it meant. A mother may be married to someone other than the biological father when the child is born. A man may learn years later that a child he has been raising is not biologically his, or that a child he never knew about exists. Each of these situations carries different legal consequences, and the right strategy depends on which one you are in.

Why Choose Sanvenero & Cittadino, LLC for Paternity and Parentage Cases

Sanvenero & Cittadino, LLC is a New Jersey law firm whose practice is centered on divorce and family law, representing individuals, families, and business owners across Monmouth, Ocean, and Middlesex Counties. Managing Partner Richard Sanvenero is a New Jersey Supreme Court Certified Matrimonial Attorney, a designation granted to lawyers who meet experience requirements and pass a written examination. He previously served as a law clerk in the Family Part of the Superior Court of New Jersey, the same court that hears paternity, custody, and support cases, so he understands how those matters are actually decided from the bench side as well as the advocate’s side. He is also trained in mediation, arbitration, and collaborative divorce, which matters in paternity cases where the parents will be co-parenting for years and a negotiated parenting plan often serves everyone better than a contested hearing.

Paternity disputes rarely stay confined to one issue. A father seeking custody may also have a business whose income will drive the support calculation. A mother seeking support may be dealing with a restraining order history that affects parenting time. Joshua Cittadino, Founding Partner, brings experience in business transactions, real estate, employment matters, and civil litigation, and Mike Canarick, Of Counsel, is a tax and estate planning attorney. Because our family law team works alongside colleagues in these areas, a client with a self-employed support obligor, a family business, or a need to update an estate plan after a child is legally recognized gets coordinated advice rather than piecemeal referrals. Our attorneys are admitted in New Jersey, New York, Florida, and the District of Columbia, and several have been recognized by Super Lawyers. Clients tell us what they value is that our team communicates clearly, returns calls, and explains each step in plain terms.

Situations That Bring Parents to a Paternity Attorney

• Establishing Paternity for an Unmarried Father: A father who was not married to the child’s mother and did not sign an acknowledgment at birth may need to ask the Family Part for a determination of parentage before he can seek parenting time or custody.
• Seeking Child Support from an Unacknowledged Parent: A mother who has been raising a child alone can ask the court to establish paternity and then set child support, including medical coverage and a share of child-related expenses.
• Genetic Testing Disputes: A man who doubts he is the father, or a mother who disputes a claim, can face court-ordered genetic testing. The results shape everything that follows, so how the testing is requested, challenged, or contested matters.
• Challenging or Reviewing a Signed Acknowledgment: A voluntary acknowledgment signed at the hospital carries legal weight, and a man who signed under pressure, mistake, or misinformation has limited windows to challenge it. These cases turn on timing and the circumstances of signing.
• Custody and Parenting Time After Paternity Is Established: Once parentage is settled, custody is decided on the child’s best interests. The January 2026 amendments to New Jersey’s custody statute made child safety a threshold issue and expanded the best-interest factors to 15.
• Children Born During a Marriage to Someone Else: When a child is born to a married mother whose husband is not the biological father, legal presumptions of parentage come into play, and the biological father’s path to recognition is more complicated.
• Modifying Existing Support or Parenting Orders: Parents with paternity orders already in place may need to modify support after a job loss, a significant raise, or a change in parenting time, or to enforce an order the other parent is ignoring.
• Parentage Issues Intertwined with Domestic Violence: Where a restraining order exists or is being sought, paternity, parenting time, and safety planning must be handled together rather than in separate tracks.

What to Do If You Are Facing a Paternity Question Right Now

The most useful first move is to find out where you stand legally. Gather whatever paperwork exists: a birth certificate, any acknowledgment of paternity signed at the hospital, prior court orders, text messages or emails in which parentage was discussed, and records of any financial support or caregiving you have provided. If you signed an acknowledgment, locate your copy and note the date, because deadlines to challenge it are limited and begin running from the signing. If you did not sign anything and are not listed on the birth certificate, you are likely starting from the position of having no enforceable rights, and the sooner a case is opened, the sooner the court can protect your relationship with the child.

Resist the urge to handle things informally in ways that undermine your position. A father who pays support in cash without records, or a mother who allows visits on an ad hoc basis without any written arrangement, can find later that the informal pattern is hard to prove or hard to change. Preserve communication, keep receipts, and avoid making statements about parentage in writing before you have talked to an attorney. If a genetic test has been requested, do not assume a home test will carry weight in court; the Family Part generally relies on testing conducted under court-recognized procedures.

Paternity and related family matters in our region are heard by the Family Part of the Superior Court in the county where the child lives or where the parties are based. For Monmouth County families, that is the Monmouth County Courthouse in Freehold. For Ocean County, matters are handled through the Ocean County Family Division in Toms River. For Middlesex County, the Family Division sits in New Brunswick, and the Middlesex Family Court has jurisdiction over paternity, custody, parenting time, child support, and domestic violence, among other family matters. The procedures differ in small ways from county to county, which is one reason local familiarity matters when you are deciding how to file and what to expect at an initial hearing.

One mistake we see repeatedly is waiting until a crisis forces the issue. A father who has been present in a child’s life for years may assume that presence creates rights, only to discover during a breakup that it does not. A mother who has not pursued support may assume the door is closed when it is not. Opening a case before the relationship breaks down completely often leads to a calmer process and a better-documented record, and it gives you the option of resolving the matter through negotiation or mediation rather than a contested trial.

How Paternity Connects to Custody, Support, and Parenting Time

Establishing paternity is not the end of the case; it is the point at which the court gains authority to decide everything else. New Jersey decides custody and parenting time based on the best interests of the child. The statute governing custody was amended in January 2026 to make the safety of children a threshold issue in every custody and parenting-time determination, and it eliminated the older presumption favoring frequent and continuing contact with both parents. Judges in contested cases are now required to make detailed findings on the record, and courts may no longer order reunification therapy absent generally accepted, scientifically valid evidence that it is safe and effective. A court also may not simply assume that a child’s reluctance to see a parent is parental alienation without investigating the reasons for it.

For a newly recognized father, these changes cut in both directions. They protect children and parents from unsafe arrangements, but they also mean a father seeking parenting time should be prepared to present a concrete, child-focused plan rather than relying on a general expectation of equal time. Where there is a history of domestic violence or child abuse, the statute provides that an offending parent may not be granted increased custody as a way of improving the parent-child relationship. Mental health professionals who provide evaluations must be state-licensed and, where abuse or domestic violence is at issue, have specific training and experience in those areas.

Child support follows from paternity and is calculated based on each parent’s income, the parenting-time arrangement, and the child’s needs, including medical coverage and child-related expenses such as childcare. Support and medical obligations generally end by operation of law when a child dies, marries, enters military service, or reaches 19, unless a court order or approved agreement provides otherwise. Where a parent is self-employed, support disputes often turn on whether reported income reflects the true economic benefit the parent receives from the business, an area where our business and tax colleagues can be useful. Support orders can also be modified later when circumstances change substantially, and they can be enforced through the court when a parent falls behind.

Frequently Asked Questions About New Jersey Paternity

What is the difference between establishing paternity and getting custody?

Paternity answers who the legal parent is. Custody and parenting time answer how decisions and time with the child will be divided. A father generally must establish paternity first, and once he does, he can ask the court to address custody, parenting time, and support in the same case.

How is paternity established in New Jersey?

It can be established voluntarily, usually through an acknowledgment signed by both parents, or by court order after a case is filed in the Family Part. When parentage is disputed, the court may order genetic testing and rely on the results to enter a finding of paternity.

Do I need a lawyer to establish paternity if both parents agree?

Not always to sign the acknowledgment itself, but an attorney is valuable when you want the agreement to include enforceable parenting time, a support amount, and terms for expenses. An acknowledgment alone does not spell out a parenting schedule, and informal agreements are difficult to enforce.

Can a father be forced to pay child support if he never signed anything?

Yes. If paternity is established by court order, typically after genetic testing, the court can set child support and order medical coverage regardless of whether the father ever signed an acknowledgment.

Can I challenge a paternity acknowledgment I signed at the hospital?

Possibly, but the window to challenge is limited and the grounds are narrow, generally centered on fraud, duress, or material mistake of fact. The longer you wait after signing, the harder a challenge becomes, so speaking with an attorney early is important.

What if the mother is married to someone else when the child is born?

The law presumes that a husband is the father of a child born during the marriage, which complicates a biological father’s path to recognition. These cases usually require asking the court to address the presumption directly and often involve genetic testing and a close look at the child’s best interests.

Does the child’s safety come into play in a paternity case?

Yes. Under the amended custody statute, child safety is the threshold question in custody and parenting-time decisions, and that applies to unmarried parents once paternity is established. A history of domestic violence or abuse can significantly affect what parenting arrangement a court will approve.

Will a home DNA test count in court?

Generally not on its own. Courts typically want testing performed under recognized procedures with proper chain of custody, so a result from an at-home kit is better treated as information for your own decision-making than as evidence for the judge.

Can a father who has been paying support informally still be denied parenting time?

If paternity has not been legally established, he has no enforceable parenting-time rights regardless of past payments. Paying support helps show involvement, but it is not a substitute for a court order or a signed acknowledgment, and it can cut against a father if the payments were undocumented.

How long does a paternity case take in the Family Part?

Timing depends on whether parentage is contested, whether genetic testing is needed, and whether custody and support are being decided at the same time. Uncontested matters can move quickly, while contested cases involving testing, custody disputes, or domestic violence allegations take considerably longer.

Can I modify child support after paternity is established if my income changes?

Yes. The court generally looks for a substantial change in circumstances, and it expects documentation such as pay records, tax returns, or business financials. Informal agreements between parents to change the amount are not enforceable without court approval.

Is it worth hiring a lawyer if the other parent and I get along?

Often yes. A cooperative relationship is the best time to put terms in writing and have the court enter them, because informal arrangements tend to fail precisely when the relationship changes. A well-drafted order protects both parents and the child.
