Understanding Child Support2017-10-13T04:29:34+00:00

Child support is an ongoing, periodic payment from one parent (payor/obligor) to another parent (payee/obligee) for the financial benefit of their mutual children. In New Hampshire, in order to receive child support, you must first file for divorce or seek assistance through the Department of Health and Human Services Division of Child Support.

New Hampshire has a set of Child Support Guidelines that the court must follow when calculating child support. The amount of child support is based on the payor and payee’s combined monthly net income, and the guideline percentage of net income that corresponds to the number of children subject to the support order. The percentages listed in the table [in the guidelines] are the calculated percentages determined in accordance with New Hampshire law (RSA 458-C).

In conjunction with the guidelines, there is a Child Support Guidelines Worksheet that determines payor’s presumptive child support obligation. The worksheet is first used to calculate the payor and payee’s combined adjusted monthly gross income amount. The corresponding guideline amount and percentage from the guideline table are then used to complete the worksheet, and determine the payor’s presumptive child support obligation amount.

However, there is an easier and quicker way to do calculate your presumptive child support payment by using the child support calculator.

At any time, a person paying or receiving child support may ask the court to change the amount of child support based on a substantial change of circumstances. If 3 years have passed since the last child support order was issued, either party may ask the court to change the order without needing to show a substantial change in circumstances.

To change child support, file a Petition to Change Court Order, together with a Personal Data Sheet.

To register or enforce a child support order from another state, file a Petition to Register Foreign Order.
