To get a copy of paternity test results, go to the source that generated them: your attorney or the court clerk if a judge ordered the test, the state child support agency if that agency arranged it, or the testing lab directly if it was a private test. The access rules, the paperwork you’ll need, and even whether a copy still exists depend on which of those paths applies to you, so start by identifying which kind of test was performed.
If the Test Was Court-Ordered
When a judge orders a paternity test in a family law case, the lab sends results to the court and typically to the attorneys for each party. You usually won’t receive a mailed copy unless you asked for one. If you were represented, your lawyer’s office is the fastest source; the results should sit in the case file.
If you no longer have counsel, or you need an additional certified copy, contact the clerk of the court that handled the case. Most family courts let you request case documents in person, by mail, or through an online records portal. You’ll generally need the case number and a valid photo ID. Fees vary by jurisdiction and are typically modest, with some courts charging nothing for parties to the case and others charging a small per-page or per-document fee.
Some jurisdictions treat paternity records as confidential or seal them outright. If your case file is sealed, you may need to file a motion asking the judge to unseal the specific documents you want. An attorney can handle this, or you can file the motion yourself if the court permits self-represented litigants. Courts scrutinize these requests because paternity results touch the privacy of the child, the mother, and the alleged father.
When a State Child Support Agency Ordered the Test
Many paternity tests aren’t ordered by a judge directly. They’re arranged by a state child support enforcement agency, which federal law requires every state to maintain procedures for.1Office of the Law Revision Counsel. 42 USC 666 – Requirement of Statutorily Prescribed Procedures to Improve Effectiveness of Child Support Enforcement If your test went through the child support office, contact that agency for the copy. It keeps its own records and can usually turn a request around faster than the court clerk.
If the Test Was Done by a Private Lab
For a private paternity test, the lab is your only source. Most reputable labs deliver results through a secure online portal, an email notification, or the mail. You’ll need the case or order number assigned when the test was purchased. If you’ve lost portal access or never received results, call the lab’s customer service line with your identifying information and order details.
The person who ordered and paid for the test controls access. In a private test, the lab has no obligation to share results with anyone who didn’t consent to the test or isn’t the account holder. If you were tested but didn’t place the order, you’ll need the ordering party’s cooperation, or you’ll need to arrange your own independent test.
Labs don’t hold records forever. AABB standards direct accredited facilities to retain records for specific periods, and the exact window depends on the edition of the standards in effect.2AABB. Standards FAQs If years have passed since your test, request the file sooner rather than later. Once the records are destroyed, no one can reconstruct them.
When There Was No DNA Test
Not every paternity determination involves genetic testing. Many fathers sign a Voluntary Acknowledgment of Paternity at the hospital when the child is born. That form is filed with the state’s vital records office, or in some states with the child support enforcement agency. If what you actually need is proof of established paternity rather than lab data, request a certified copy of the acknowledgment from whichever office holds it. Either parent, the child’s legal guardian, or an attorney can typically request the copy, though most states require a notarized signature to process it.
Reading the Report Once You Have It
Paternity reports look dense, but two numbers do almost all the work. The Combined Paternity Index (CPI) multiplies the likelihood ratios from each genetic marker tested. A CPI of 1,000,000 means the child’s DNA pattern is one million times more likely if the tested man is the biological father than if a random unrelated man were. The Probability of Paternity converts that CPI into a percentage. Labs typically use a neutral 50/50 starting assumption and let the genetic evidence move the number.
In practice, results land in one of two places. If the tested man is not the biological father, at least one marker won’t match, and the report will say “excluded” with a 0% probability. If he is the biological father, every marker matches and the probability comes in at 99.9% or higher. There is almost never an ambiguous middle. Federal law directs states to create a presumption of paternity when genetic testing reaches a threshold probability, and most states set that threshold at 99% or above.1Office of the Law Revision Counsel. 42 USC 666 – Requirement of Statutorily Prescribed Procedures to Improve Effectiveness of Child Support Enforcement At that level, some states treat it as a conclusive presumption, meaning paternity is legally established unless the result itself is successfully challenged.
Who Is Allowed to Receive a Copy
Access depends on the context of the test. In a court-ordered test, the judge decides who receives the results, and unauthorized disclosure can violate a court order. In a private test, the person who ordered it controls distribution. For any test involving a minor, a biological parent or legal guardian must consent to the child’s participation. In legal proceedings a court can order testing over a parent’s objection, but in private testing consent from someone with legal authority over the child is always required. AABB standards specifically require consent from each tested person, or from an individual with legal authority over a minor or legally incompetent adult, before samples are collected.3AABB. Proposed Standards for Relationship Testing Laboratories
HIPAA is not the automatic shield many people assume it is. HIPAA’s genetic information provisions mainly govern how health plans use genetic data for underwriting and eligibility decisions.4U.S. Department of Health & Human Services. Genetic Information Whether a standalone paternity lab qualifies as a HIPAA-covered entity depends on whether it meets the definition of a health care provider that conducts certain electronic transactions, and many direct-to-consumer DNA labs don’t. Most states have their own genetic privacy laws that restrict how labs share results, and accredited labs follow internal confidentiality protocols regardless of HIPAA status. The practical takeaway: expect a reputable lab to require proper authorization before releasing your file to anyone, but don’t rely on HIPAA to force disclosure or block it.
If the Copy You Receive Looks Wrong
Challenges to paternity results almost always turn on one question: was the chain of custody intact? AABB standards leave little room for error. Sample collection must be performed or witnessed by a neutral person with no interest in the outcome. Collection materials cannot be in any participant’s possession before or after the process. Every sample must carry a label with a unique identifier, the collection date, and the collector’s initials, and the participant must verify that label in writing. Samples must be packaged in tamper-evident containers and shipped through a trackable service.3AABB. Proposed Standards for Relationship Testing Laboratories
A documented break in that chain gives you grounds to challenge. If the collector failed to sign the required forms, if samples were left unattended, or if the lab cannot produce documentation showing how materials moved from collection through analysis, a court may exclude the results. Federal law reinforces this by requiring that admissible results come from an accredited lab using a generally reliable testing method, and by allowing parties to contest results in writing before a hearing.1Office of the Law Revision Counsel. 42 USC 666 – Requirement of Statutorily Prescribed Procedures to Improve Effectiveness of Child Support Enforcement Results from an unaccredited lab face a steeper problem: because federal law ties admissibility to accreditation, a test from a facility not approved by a designated accreditation body such as AABB may simply be inadmissible. You can verify a lab’s current AABB accreditation through the AABB directory of accredited relationship testing facilities.5AABB. AABB-Accredited Relationship (DNA) Testing Facilities
Fraud or coercion is a separate basis. If someone alleges that samples were swapped, that a participant was coerced, or that identity verification was skipped, a court can order a retest under tighter supervision. Fraudulent interference with paternity testing can carry criminal consequences in some jurisdictions.
One caution on timing. Many states impose deadlines for challenging a paternity determination, whether it was established by court order, voluntary acknowledgment, or genetic testing. The windows vary widely, from as little as 60 days to rescind a voluntary acknowledgment in some states to two years or longer for other challenges. Missing the deadline can permanently bar your claim, so consult an attorney promptly if you believe a result is wrong.
One boundary worth flagging: at-home paternity tests use the same DNA science as legal tests, but because participants collect their own samples without independent identity verification, the results cannot be used in court for child support, custody, or benefits claims.6Labcorp.
