Because the formula is mandatory, there is very little room for negotiation in determining child support payments. However, as with most formulas and software, the outcome is determined by the information that is input.
The good news is yes, child support arrears can potentially be forgiven. You would need to have a joint petition filed along with the other parent though, showing that you are both in mutual agreement and jointly requesting that the arrears be waived or forgiven.
Only a petition to terminate child support in NY cancels the payments after the court reviews the specific circumstances used as grounds for termination. However, either one of the parents can request a modification to the settlement if there is a significant change in the earnings of the noncustodial parent.
On rare occasions, child support can be waived by filling out a Deviation Addendum. Reasons to deviate can vary, however, they must be approved by the local Friend of the Court and Prosecuting Attorney.
There are two ways you can ask to have arrears discharged (canceled). You can fill out the Request to Discharge State-Owed Debt form asking the Friend of the Court (FOC) to discharge support debt you owe to the State of Michigan only.
In Michigan, child support obligations normally last until the child turns 18 years old, but can continue up until the age of 19 and a half if the child is still in high school and lives full-time with the parent that gets child support.
YOU can't. The only way child support can be canceled is through a court order, or the completion of the court order--the child comes of age, and no more support is obligated. If the custodial parent does NOT want to receive the support, the custodial parent must apply to the court to have the support end dated.
