the state involved is new hampshire.
the first question is the original support order cam from rhode island. that order was for a monthly amount, with no set due date, just a monthly payable amount.
the new court order form the new state has a set due date in the middle of the month.
before the new raised amount was set, the father paid the old order on the first of the month. When the new order was set dad paid the difference between what was already paid on the old order and the new order.
The state will not acknowledge anything predating the midmonth court order,unless the mom agrees. mom will not and is looking to get paid for that month "twice" dad is now in arears to the new state for the amount of the old order.
if dad had paid the old child support order AFTER the new one went into effect she could not do this. as the state would have acknowledged that check as "thiers".
Does the father have any chance in compelling mom to accept this old support as part of the new support?
