If the parties wish to end their child support agreement before the child reaches the age or status of emancipation, they must prove a change of circumstance has occurred. The two parties would then have to input new information, such as a change in income, into the child support worksheet to do determine an updated amount, which could reduce the original number or bring it down to zero.
If nothing has changed between the parties, a termination of child support payments would not be allowed, and the number calculated by the child support worksheet would remain the same. An attorney in the area could help utilize the worksheet to end the child support payments.
