First, you should work with your ex-spouse to determine if they might be agreeable to a modification in child support terms. If you agree, then you only need to ask a judge to approve the modification.
If you and your spouse cannot agree on modified child support, you will need to go to court. The court can grant either a temporary or permanent modification, depending on your individual circumstances.
If you are seeking an increase in child support, you may be able to get a temporary modification if your child has had a new medical condition or emergency, there is an increase in school, daycare or other cost of living expenses. If you have suffered a job loss or disability you may also qualify for an increase in child support until you are able to find new employment.
Conversely, if you are seeking a decrease in child support, the court may grant it if you have suffered a job loss, pay cut, disability or if your income has changed for any other reason. If your spouse has an increase in income from a new job, pay raise or remarriage, you may also qualify for support modification.
If you are the paying spouse, it is important that you contact a divorce attorney to file a modification of support request as soon as possible. If you violate the terms of your current court order by not paying, the consequences could be severe.
