Arizona Petition for Paternity is a legal process used to establish the father of a child when there is no legal record of paternity. This is done through a court hearing, in which a judge will decide the paternity of the child. There are two types of Arizona Petition for Paternity: an administrative hearing and a contested hearing. An administrative hearing is used when both the mother and father agree to the paternity, while a contested hearing is used when the parents do not agree to the paternity. The court will consider evidence from both the mother and father, such as DNA tests, witness testimony, and other evidence, to make its determination. Once the paternity is established, the court may make orders regarding child support, custody, and visitation.
