Paternity Testing in San Antonio, Texas
San Antonio grew up around the Alamo and the Spanish colonial missions that now form a UNESCO World Heritage site, and today's River Walk draws visitors through the heart of a city that's also home to several major military installations. As Texas's second-largest city, San Antonio sees a genuinely wide range of Bexar County residents, and paternity testing questions here come from just as varied a group.
Contact Our TeamWhich test do you actually need?
Most people don't realize there are two different tests until they start looking — and they serve very different purposes.
A private at-home test fits if you're testing purely for personal certainty — a self-collected cheek swab, mailed in, private results. If the outcome needs to matter in a Bexar County court case or a child support proceeding, the legal version is required, with a supervised, documented collection process built to hold up as evidence.
Informational Testing
A private, self-collected cheek swab, mailed in for fast results — right if you just want to know for yourself.
- Collect at home, on your own time
- Results in a few days
- For personal peace of mind only — not usable in court
Legal Testing
A supervised, chain-of-custody collection — required if the result needs to hold up in custody, support, or immigration matters.
- Photo ID verified at collection
- Witnessed, documented process
- Accepted by Texascourts & agencies
In Texas, a legal paternity test with a documented chain of custody may be used to establish paternity for child support, custody, or birth certificate purposes; informational tests are not accepted by Texas courts.
