Should we have a Legal or Informational DNA Paternity Test?

What Makes a Paternity Test Admissible in Court?
A legal DNA paternity test should be performed if the paternity test report will be used for any legal purpose. This would include establishing paternity for Social Security, child support, inheritance, health insurance, or any other time that proof of paternity is necessary.
An Informational (non-legal) DNA paternity test may be used when the information is only for personal informational purposes. There are a variety of circumstances when a non-legal paternity test is adequate. An adult child may wish to verify that the man who raised them is truly their biological father, or a legal father of a child may be less than certain that the child is truly his biological child, or any time that the test will not be used to establish identity or for a legal purpose. A non-legal DNA paternity test is for personal knowledge only. It is of no use for legal purposes.
To be admissible in court a DNA paternity test must meet two requirements.
First, the test must be performed by a DNA paternity testing laboratory that is accredited by the American Association of Blood Banks (AABB).
Second, the DNA specimens used in the DNA paternity test must have been collected, shipped and stored in a manner that establishes a good chain of custody for the specimens. This allows the DNA paternity testing laboratory to prove that the individuals whose names appear on the paternity test are truly the individuals who provided the DNA samples that were DNA paternity tested.
The chain of custody begins with the DNA specimen collector attaching a picture of the collected individuals to the form used to collect the DNA specimens (often referred to as a Specimen Collection Form or Chain of Custody Form). The DNA collector also checks a photo ID such as a driver’s license, Additional procedures may also be followed. The specimens must then be shipped to the paternity laboratory and stored at the laboratory in a manner that ensures the security of the specimens.
