Legal Question in Family Law in Texas

A father with access to a child can get a DNA test run. Of course, if the child is not an infant, the child will know that he is doing it, probably.

It can be accurate if done by a reputable lab with good controls. As far as legal, it depends on what you mean. It is not illegal to do it. If you are asking whether it is able to be used in court, that depends. I would not want to present a DNA test that is not court ordered so that I can be sure that all of the proper protocols were followed. The court is far more likely to accept a test that the court ordered. To get the more informal test accepted by the court, you would probably have to have a scientist from the law testify.

The father should get an attorney and listed to him or her.
