How to Get a Court-Ordered Paternity Test: Step-by-Step

When voluntary cooperation breaks down and one party refuses to participate in paternity testing, the legal system provides a clear mechanism: the court-ordered paternity test. Whether you are a father seeking to establish your parental rights, a mother pursuing child support, or a man disputing a claim of paternity, understanding the step-by-step process of obtaining a court order for DNA testing can save you months of confusion, unnecessary expense, and emotional turmoil. Every state in the U.S. allows parties to petition for court-ordered genetic testing, though the exact procedures, timelines, and costs differ by jurisdiction.

Step 1: Determine Whether You Have Legal Standing

Before you file anything, you need to confirm that you have standing to request a paternity test through the courts. Standing is the legal right to bring a case. In paternity matters, standing is typically granted to the biological mother, the alleged father, a child's legal guardian, or a state child support enforcement agency. If you are a man listed on the birth certificate, you generally have standing to challenge paternity. If you are an alleged father who was never married to the mother and is not on the birth certificate, you can still file a paternity action to establish your biological connection. Some states also allow grandparents or the child themselves to petition once the child reaches a certain age. If you are uncertain whether your situation qualifies, a brief consultation with a family law attorney in your county can clarify your position before you invest time in paperwork.

Step 2: File a Petition to Establish or Disestablish Paternity

The formal process begins when you file a petition with your local family court. This document is sometimes called a Petition to Establish Paternity, a Complaint for Paternity, or a Motion for Genetic Testing, depending on the state. Most county courthouses and state judicial websites provide fillable forms specifically for paternity actions. The petition typically requires basic identifying information about both parents, the child's name and date of birth, and a statement explaining why genetic testing is being requested. Filing fees range from $50 to $350 in most jurisdictions, though fee waivers are available for individuals who demonstrate financial hardship. Once filed, the court clerk assigns a case number and schedules an initial hearing.

Step 3: Serve the Other Party

After filing, you must legally notify the other party that a paternity action has been initiated. This is known as service of process and is a constitutional requirement. Service can be accomplished through a county sheriff, a licensed process server, or in some jurisdictions by certified mail with return receipt requested. The served party then has a window, usually 20 to 30 days, to respond to the petition. If the other party fails to respond, you may be able to obtain a default judgment, which can include an order for genetic testing. Proper service is critical because any court order obtained without valid service can be challenged and overturned later.

Step 4: Attend the Initial Court Hearing

At the hearing, a family court judge reviews the petition and any response filed by the opposing party. In many straightforward cases, the judge will order genetic testing at this first appearance. If the other party contests the need for testing or raises procedural objections, the judge may schedule a second hearing or require additional documentation. Courts overwhelmingly favor ordering DNA tests when paternity is genuinely in dispute because the results serve the best interest of the child by establishing legal parentage with certainty. Judges have broad discretion to compel testing, and refusal to comply with a court order can result in contempt of court sanctions, fines, or an adverse inference where the court presumes paternity against the refusing party.

Step 5: Complete the DNA Test at an Approved Facility

Court-ordered DNA tests must be performed at an AABB-accredited laboratory with strict chain-of-custody protocols. This means the sample collection is supervised, identification is verified with government-issued photo ID, photographs are taken, and the samples are sealed and documented at every step to prevent tampering. The testing itself is the same buccal swab collection used in at-home kits: a painless cheek swab from each participant. The key difference is the evidentiary integrity of the process, which makes the results admissible in court. Testing costs for court-ordered paternity tests typically run between $300 and $600. Some courts assign the cost to the petitioner initially, while others split costs or assign them to the party whose position is disproven by the results.

If you are still in the early stages of questioning paternity and want a low-cost preliminary indication before committing to the legal process, the TrueDadz AI-powered assessment provides a fast, private, and affordable starting point at $14.99. While it is not a substitute for legal DNA testing, it can help you make a more informed decision about whether to proceed with a court petition.

Step 6: Receive and Interpret the Results

AABB-accredited labs typically return court-ordered results within 5 to 10 business days after sample collection. The report is sent directly to the court and to both parties or their attorneys. Results are expressed as a Combined Paternity Index and a Probability of Paternity percentage. A probability of 99% or higher confirms paternity, while a 0% result conclusively excludes the tested man as the biological father. These results carry enormous legal weight and usually trigger the next phase of the case, whether that involves establishing child support obligations, granting custody or visitation rights, or removing a man's name from a birth certificate.

What Happens After the Results Come In

Once DNA results are entered into the court record, the judge proceeds to adjudicate the paternity case. If paternity is established, the court can simultaneously enter orders regarding child support, custody, visitation, and the child's legal name or birth certificate amendment. Child support can be ordered retroactively to the date of the child's birth in many states, which can represent a substantial financial obligation. If paternity is excluded, the court may vacate any existing support orders and direct the vital records office to amend the birth certificate. The entire process from filing the initial petition to receiving DNA results and a final court order typically takes 2 to 6 months, though contested cases or crowded court dockets can extend the timeline.

Estimated Costs for the Full Process

Adding up all potential expenses, a court-ordered paternity case without an attorney may cost $400 to $900 total, including filing fees and testing. With attorney representation, costs climb to $1,500 to $5,000 or more depending on whether the case is contested and how many hearings are required. Some states have free paternity establishment programs run through the child support enforcement office, particularly when the mother is receiving public assistance. These programs handle the filing, service, and testing at no direct cost to either party, making court-ordered testing accessible regardless of income level.
