Arizona Information about Responding to a Petition to Establish Paternity, Legal Decision Making and Parenting Time is generally provided by the Arizona courts. The legal process of paternity establishment is initiated when one of the parents files a petition with the court. The court will then review the petition and if paternity is established, will issue an order that will determine legal decision-making and parenting time rights. There are two types of Arizona Information about Responding to a Petition to Establish Paternity, Legal Decision Making and Parenting Time: 1. Voluntary Acknowledgment of Paternity: This is when both parents voluntarily agree to the paternity of the child and sign the appropriate documents with the court. If the paternity is established in this way, the court will then issue an order to determine legal decision-making and parenting time. 2. Genetic Testing: If the parents do not agree to the paternity of the child, the court can order genetic testing to be done. If the results from the genetic testing show a 99% or higher probability of paternity, the court will then issue an order to determine legal decision-making and parenting time.
