when a non physical custody parent is jailed for violent crime would this allow custody to be removed in a case

If proper paperwork is filed with the Family Court in Arizona for modification, the Court has to consider the best interests of the child, including consideration of whether the child has witnessed or been affected by domestic violence.  If the violent parent is being released from jail or prison, the other parent should consider filing a request for an emergency temporary order in the family court that will limit the violent parent's access to the child.  An Order of Protection can be obtained from the Superior Court while the Family Court matters are being pursued, but the Superior Court can only put the child on a protective order in limited circumstances.  The family court judge is the most appropriate person to address changing of the family court orders so that the child is protected.
