A paternity test is considered legal when a chain of custody is properly established. Which ensures the identity of the testing participants and keeps the integrity of the DNA samples from the time of collection through the completion of testing process.

Here’s what makes a paternity test legal:

  • Identification: All participants must present valid, state-issued photo identification at the time of sample collection.
  • Third-Party Sample Collection: DNA samples must be collected by a neutral, third-party collector. Participants cannot collect their own samples.
  • Lab Accreditation: The testing laboratory must be accredited by the AABB, such as our partner DNA testing laboratory. This accreditation\ ensures your results will be accepted by all family courts and state agencies nationwide.
  • Chain of Custody (COC): A detailed, untampered, documented process tracking a DNA test from the time of collection to the completion of results.
  • Results: Depending on the legal purpose (e.g., child support, immigration, or court proceedings), the laboratory may be required to send results directly to the requesting agency, such as USCIS or directly to a family court judge. In all cases the client will receive a copy of their DNA results for their records.

Please keep in mind, each case is handled individual basis, and result delivery requirements can vary based on the specific legal use. Contact our office at 800-219-4584 to speak with DNA Consultant today for free phone consultation.

A legal paternity test is needed when a family court judge requests it, when an state agency such as USCIS or an embassy requires it, or when individuals plan to submit a paternity petition to establish a child’s paternity or add a father’s name to a child’s birth certificate.

These situations typically require a legal paternity test.

Pricing for legal paternity testing starts $350.00. Learning more about paternity testing services here.

A standard legal paternity test establishes biological relationships for most legal situations by following a documented chain of custody for sample collection and handling.

An immigration paternity test requires the same chain of custody process but includes additional documentation and paperwork to meet immigrant visa evidence submission guidelines.

  • Immigration cases typically involve an official request for evidence letter from a USCIS or an embassy.
  • It also requires that a proper chain of custody be established

The main difference lies in the additional documentation required for immigration purposes, beyond those required for a standard legal paternity test. Below is a comparison chart of each legal testing type.

Frequently Asked Questions

The average turnaround time for results is 3 business days.

Yes. All legal DNA testing services we provide are under the strict supervision by our partner accredited laboratory.

Does the mother need to be involved with a paternity test?

A mother’s participation is not required but is recommended to strengthen the DNA analysis. Although, when establish paternity through family court, a judge may recommend the mother to participate in the paternity test.

No, an at-home paternity test cannot be upgraded to a legal paternity test. Please keep in mind, legal tests require a chain of custody and At-Home paternity tests do not require one to be established.

We recognize some facilities may claim to offer At Home DNA Test upgrades, we do not provide this option because it would compromise the integrity of the chain of custody, which is required for a test to be legally admissible.

In order to maintain the integrity of your results and ensure they are admissible as court evidence, we always recommend performing a legal paternity test from the start. This means a proper chain of custody will be established allowing your DNA results to meet the evidence submission requirement for all legal situations

What if one party refuses to participate?

A party may refuse to participate in a DNA paternity test because DNA testing is voluntary.

A person can opt to file a paternity petition in family court. The court may issue an order requiring the alleged parent to appear for testing. The refusing party risks being held in contempt of court and facing a judgment in favor of the other party if they do not comply with a court order.

Legal counsel helps participants understand state-specific paternity laws. No party can force an adult to undergo paternity testing. Family reconstruction DNA testing using the alleged father’s relatives may provide an alternative when the alleged father refuses to participate.
