Is the legal DNA test different from the informational DNA test?
No. The DNA tests are exactly the same. The difference is that legally-binding tests require a witness, proof of identity, and special chain of custody procedures. The basic Home DNA or Paternity Test Kit therefore is not legally binding. It is intended as a discrete and private way whereby families can resolve questions without involving outside parties. The GTL also offers a Legally Binding or Legal Home DNA Test Kit that requires a disinterested witness to oversee sample collection and verify identities and chain of custody.
