A legal paternity test uses professional sample collection, participant identity verification, required documentation, and a recorded chain of custody. The laboratory then analyzes the samples and issues a report through the appropriate delivery process.
Before scheduling, confirm what the court, agency, attorney, or other receiving organization requires. A documented collection is important, but a service described as “legal” does not guarantee that every report will satisfy every proceeding.
This guide focuses on standard post-birth paternity testing. Prenatal testing and indirect relationship testing have different sample or participant requirements.
Step 1: Confirm Why the Report Is Needed
Start by identifying the intended recipient and purpose. A parentage case, child-support proceeding, inheritance matter, or birth-record request may involve different instructions.
Ask whether the receiving organization requires a particular laboratory, case number, court order, participant arrangement, or direct report delivery. Share those instructions with the provider before paying.
If a child-support case is already open, contact the agency first. Under 45 C.F.R. § 303.5, state child-support agencies use laboratories meeting applicable requirements and arrange testing in eligible contested cases. An independently purchased test should not be assumed to replace that process.
For the broader legal context, read what legal paternity means.
Step 2: Determine Whether Testing Is Voluntary or Directed
Legal testing and court-ordered testing are not identical.
Some people voluntarily arrange a documented legal collection. Others must follow instructions issued through a court or agency case.
DDC’s explanation of court-ordered and privately arranged legal tests distinguishes these pathways. Its central point is that an official-use collection does not always require an order from a judge.
However, if a formal direction already exists, follow its requirements. Do not substitute another kit, laboratory, or appointment without confirming that the change is permitted.

Step 3: Confirm Participants and the Performing Laboratory
The alleged father and child are generally the primary participants in a direct post-birth paternity comparison. The biological mother may also participate when recommended by the laboratory or required for the case.
Disclose relevant family circumstances before collection. In particular, tell the provider if possible fathers are biologically related or if a required participant cannot provide a sample.
Ask which laboratory will perform the analysis and what accreditation is relevant to the service. You can check the AABB directory of accredited relationship-testing facilities. The directory distinguishes facilities performing testing from certain accredited collection and verification/reporting locations.
Do not assume the seller, collection location, and performing laboratory hold identical credentials.
Step 4: Schedule the Required Collection Arrangements
Request an appointment at a location that supports the selected legal collection process. Confirm that it can accommodate the required participants and any case-specific instructions.
Participants do not necessarily need to attend the same site or appointment. AABB’s relationship-testing FAQ states that accredited facilities can arrange collections together or separately according to the parties’ needs.
Coordinate separate collections through the provider rather than having participants independently order unrelated tests.
Before traveling, confirm the appointment details, collection location, documents, fees, and any materials you have been instructed to bring. Availability varies by location and participant needs.
Step 5: Prepare Identification, Authorization, and Paperwork
Adults generally need current government-issued photo identification. A child may need identification or supporting documents accepted by the laboratory and collection site.
A parent, legal guardian, or another person with appropriate legal authority may need to authorize the minor’s testing. Court orders, attorney letters, agency paperwork, or a case number may also be required.
Confirm the actual list before the appointment. Do not assume the same documents are accepted everywhere or that any adult accompanying a child can authorize collection.
The mother’s DNA being optional in a particular comparison does not resolve who can authorize the child’s sample. Biological participation and legal authority are separate questions.
For preparation details, read five tips for preparing for a paternity test.
Step 6: Attend Professional Identification and Sample Collection
At the appointment, the collector follows the case instructions to verify identities, complete paperwork, and collect the required samples.
Standard post-birth paternity testing commonly uses cheek swabs. Cleveland Clinic’s paternity-testing overview describes collecting cheek cells from the child and alleged father for laboratory comparison. A routine cheek-swab test does not require a blood draw simply because it is legal testing.
Follow the provider’s preparation directions. Do not replace them with a universal eating, drinking, or oral-product waiting period found elsewhere.
If identification is missing, a participant cannot attend, or a document appears incorrect, raise the issue before collection is completed. Do not sign inaccurate information or attempt an informal workaround.
Step 7: Document and Maintain Chain of Custody
Chain of custody records how samples are identified, collected, secured, transferred, and submitted for analysis. It connects the biological material to the documented participants and collection event.
AABB explains that its accredited facilities follow validated procedures to maintain traceability from case initiation through reporting.
This is why self-collected swabs cannot simply be presented as though they were collected through the legal pathway. A friend’s signature, careful packaging, or a photograph does not automatically replace the required professional process.
Follow the collector’s instructions for handling and submission. Do not open, replace, or alter collected materials contrary to the documented process.
Step 8: Laboratory Receipt, Review, and DNA Analysis
The laboratory receives the samples and associated documentation, checks the case requirements, and performs the genetic comparison.
A paternity analysis evaluates selected genetic locations. It is not a complete ancestry analysis or medical genetic screening panel.
DDC’s guide to reading paternity reports describes the genetic-marker table, Combined Paternity Index, reported Probability of Paternity, and final conclusion. It also explains that additional analysis may be needed in certain circumstances, including related possible fathers.
A sample or documentation problem may require clarification or recollection. Do not assume an advertised processing estimate overrides those requirements.
Read paternity-test sample problems for the distinction between contamination, insufficient material, and identification errors.
Step 9: Receive the Report Through the Appropriate Channel
Confirm who is authorized to receive the report and whether it must be delivered directly to a court, agency, attorney, or another recipient.
Do not assume every case uses the same portal, email process, or mailing arrangement. GameDay DNA’s current service information advises customers to establish delivery requirements before testing.
Ask when the processing period begins and whether the estimate includes weekends, shipping, or additional review. AABB advises obtaining case-specific timing from the facility arranging testing and notes that extended analysis can take longer.
Laboratory turnaround is separate from the time a court or agency may need to review evidence or issue a decision.
Step 10: Follow the Legal or Administrative Next Steps
Receiving a DNA report does not necessarily complete the parentage, support, inheritance, or birth-record process.
Ask the office handling your matter whether the report has been received and what filing, hearing, or other step remains. Do not assume the laboratory files a petition, changes a birth certificate, or issues a parenting order.
For the relevant follow-up questions, read paternity testing and child support or changing a father’s entry on a birth certificate.
If you disagree with a result, contact the provider and obtain advice about any official objection procedure or deadline. Additional testing in an agency case may follow rules different from a private repeat purchase.
What if the Alleged Father Cannot Participate?
Tell the provider before scheduling.
An indirect comparison involving available grandparents, siblings, or an aunt or uncle may be considered, but it is not the same test as a direct father-child comparison. Confirm that the requesting organization will consider the proposed evidence and have the laboratory review the family arrangement.
Read DNA testing without the father before ordering an alternative.
Immigration Testing Uses a Separate Pathway
GameDay DNA does not provide, collect, schedule, or coordinate immigration DNA testing. It refers immigration inquiries directly to DDC.
AABB states that U.S. visa, passport, and citizenship testing cases must be initiated directly between the petitioner and an appropriately accredited relationship-testing facility. Do not begin those cases with a standard GameDay DNA order.
Use the immigration DNA testing referral page for the appropriate starting point.
Frequently Asked Questions About the Legal Paternity Test Process
What makes a paternity test legal?
The process includes professional collection, participant identity verification, required documents, and chain-of-custody records. The report must also meet the requirements of the organization receiving it.
Do I need a judge’s order before scheduling?
Not always. Voluntary legal testing can be arranged in appropriate circumstances. If a case is open or an order already exists, confirm the required pathway before scheduling independently.
Who needs to attend?
The child and alleged father are generally the primary participants. The mother may be recommended or required. Confirm the laboratory and case instructions before booking.
Can participants attend different locations?
Yes, separate collections can be arranged when appropriate. Coordinate them through the provider so the documentation and samples remain linked to the correct case.
What identification should I bring?
Adults generally need current government-issued photo identification. Documents for a minor, collection authorization, and case paperwork may also be required. Confirm the exact list before traveling.
Can I collect the swabs at home and bring them to the appointment?
Do not assume that will meet the legal process. Self-collected material lacks the professional identity verification and witnessed collection required by the selected legal pathway. Ask the provider before collecting anything.
Are legal reports automatically accepted in court?
No blanket guarantee applies. Confirm the receiving organization’s laboratory, collection, documentation, and delivery requirements before testing.
How much does the test cost?
Request the current complete quote for the participants and collection arrangements. Confirm tax, collection charges, separate locations, shipping, and optional services rather than relying on a universal price range.
Read DNA testing costs and payment options for comparison questions.
How long does the process take?
Separate appointment scheduling, sample shipping, laboratory analysis, report delivery, and legal review. Ask the provider for the current laboratory estimate and the relevant authority about the proceeding’s timeline.
What if someone refuses to participate?
A provider cannot compel attendance. If a formal proceeding is involved, contact the agency or a qualified attorney. Consequences depend on the applicable process; refusal is not itself a DNA finding.
Read whether a paternity test can be refused for more detail.
Conclusion: Confirm Requirements Before Collection
A legal paternity test is a documented process—not just a cheek swab followed by a report. The sequence begins with case requirements, participant arrangements, and identification, then continues through professional collection, traceable handling, laboratory analysis, and appropriate report delivery.
Choose the correct pathway before samples are collected, and keep laboratory findings separate from the legal decisions that may follow.
