Paternity tests can be ordered by the court to prove or disprove the question of biological fatherhood. This is usually requested in cases when financial support is needed for the child. For example, court ordered paternity testing would be needed to settle disputes of alleged fathers who refuse to accept paternity to provide child support. They can also be requested so biological fathers can gain visitation rights, to change the name on a birth certificate, for child custody issues and in immigration cases.

Because legal paternity tests need to stand as evidence in court they need to be performed under specific instructions, known as chain of custody. A trained sample collector would need to ensure that the correct individual is providing the sample by checking ID, taking photographs and getting signed paperwork. A medical professional, such as a GP, may also be able to collect DNA samples (usually for a fee) and send them securely back to the Alphabiolabs laboratory for testing. As such, the DNA sample does not leave the custody of those who are legally responsible for ensuring the authenticity of its results. Legal samples can also be collected for free at our nationwide Walk in Centres.
