There are many parents in Arizona. Many of these parents had their children with their spouse, while many others had children with people to whom they are not married. If a man is not married to the mother of his child, the law does not immediately recognize him as the father. In order to be legally recognized, paternity must be established.
There are a couple of ways to do this, and it is important to establish paternity because fathers' rights, including the right to receive child support or obtain visitation and custody, do not exist until paternity is established. One way to establish paternity is by having both parents sign an acknowledgement of parentage naming the man as the father. However, if this is not done, the parents must undergo genetic testing. The man will be the presumed father if the results of the genetic test indicate there is at least a 95% chance that he is the father.
