AZ SB1720

Establishes a rebuttable presumption that equal parenting time (at least 45% of overnights annually for each parent) is in the child's best interests when both parents are fit and live within 25 miles of the child's school.

Removes the equal parenting time presumption in cases involving significant domestic violence, active orders of protection, children under age six, court-ordered treatment programs not yet completed, or when equal time would endanger the child.

Requires courts to make specific written findings explaining why equal parenting time is not in the child's best interests when ordering unequal arrangements.

Adds developmental factors to custody determinations, including the child's age, attachment needs, ability to tolerate transitions between households, and need for stability and emotional security.

Prohibits courts from ordering equal parenting time over the objection of a child of suitable age and maturity unless specific findings show the arrangement will not endanger the child.
