On the other hand, the Obligor (person who pays child support) may need to ask for a child support reduction, for the same reasons. The Obligor may have a medical condition or disability, be unable to work through no fault of his/her own, or be able to show that the child is actually living with him/her most or all of the time.
During a divorce, any unusual and all relevant facts should be discussed with your attorney. After the divorce is final, any significant change in circumstances (health, employment, finances, where the child is living) may lead to a petition requesting that the judge order an increase or decrease in the amount of child support owed.
