Does child support provide DNA Testing services in New Jersey?

No. New Jersey Child Support does not perform or provide DNA testing services. Child support cases involving disputed paternity are handled through the New Jersey Family Court process. When legal paternity is contested, the court may require a legal DNA test before making a paternity determination.

How Is Paternity Established in New Jersey?

Paternity is established in New Jersey by either signing a Certificate of Parentage (COP) or obtaining a court order based on legal evidence, including DNA testing when necessary. Establishing paternity creates a legal father-child relationship that allows the court to determine parental rights and responsibilities such as child support, custody, parenting time, inheritance rights, and access to government benefits.

Parents who agree on the child's biological father may voluntarily sign a Certificate of Parentage. When paternity is disputed or uncertain, either parent or a government agency may petition the court to establish paternity. The court may order a legal DNA paternity test performed under a documented chain of custody before issuing a final judgment.

Ways to Establish Paternity in New Jersey

Sign a Certificate of Parentage

A Certificate of Parentage is the fastest method for establishing legal paternity when both parents agree.

Parents may sign the Certificate of Parentage:

At the hospital following the child's birth.
After the child's birth through an authorized agency.
Without appearing before a judge when both parties voluntarily acknowledge paternity.

Once properly executed, the Certificate of Parentage carries the same legal effect as a court order establishing paternity.

Obtain a Court Order

A court establishes paternity when the biological father is disputed or unknown.

A paternity action may be filed by:

The child's mother
The alleged father
The child's legal representative
A government agency seeking child support

The court reviews all available evidence. When biological parentage is questioned, the judge commonly orders legal DNA testing before making a determination.

Does New Jersey Require DNA Testing to Establish Paternity?

No. New Jersey does not require DNA testing when both parents voluntarily sign a Certificate of Parentage.

DNA testing becomes necessary when:

One party denies paternity.
The court requires biological proof.
The alleged father requests genetic testing.
Existing evidence is insufficient to establish paternity.

Legal DNA testing typically identifies the biological father with greater than 99.9% probability of paternity or excludes an unrelated man with a high degree of scientific certainty.

What Happens After Paternity Is Established?

After legal paternity is established, the court may determine:

Child support obligations
Child custody
Parenting time (visitation)
Health insurance responsibilities
Medical history access
Inheritance rights
Eligibility for Social Security and other government benefits

Establishing paternity creates legal rights for both the child and the father.

Should You Sign a Certificate of Parentage If You Are Unsure?

No. Anyone uncertain about biological paternity should consider completing a legal DNA paternity test before signing a Certificate of Parentage.

Once signed, the Certificate of Parentage establishes legal fatherhood. Although New Jersey law provides limited circumstances for challenging an acknowledgment, reversing legal paternity often requires court proceedings and may become significantly more difficult after time has passed.

A legal DNA test performed before signing provides objective biological evidence and reduces the risk of future legal disputes.

How does DNA testing affect child support cases?

DNA testing affects child support cases by establishing or excluding biological paternity. New Jersey courts use legal DNA test results to determine whether a man has a legal obligation to financially support a child. When a legal DNA test confirms paternity, the court may establish child support after considering other applicable laws and guidelines. When DNA testing excludes a man as the biological father, the court generally will not establish paternity based on that DNA evidence alone.

DNA testing does not automatically create a child support order. Instead, it provides scientific evidence that the court may use when determining legal parentage.

Why Is DNA Testing Used in Child Support Cases?

A court may order DNA testing when the child's biological father is disputed or has not been legally established.

Legal DNA testing helps the court:

Determine whether the alleged father is the child's biological father.
Establish legal paternity before entering a child support order.
Resolve disputes when either parent questions paternity.
Prevent child support obligations from being assigned to the wrong individual.

Modern legal DNA paternity testing typically confirms paternity with greater than 99.9% probability or excludes a man as the biological father with a high degree of scientific certainty.
