Past Support
Support that a parent owes to the other parent between the time the parties before a court order for support is put into place. The time period for past due support is the time between the parties began living separte or apart and the date a child support order is put in place. Under A.R.S. 25-320(C), the Court can order up to three years of past child support. It can go beyond three years if it makes written findings that doing so is appopriate (this is extremely rare). No interest accrues of past support until the Court actually enters a judgment finding that it is owed.
