If there has already been a judgement regarding child support you will need to speak with a legal representative regarding the modification of child support. Modifying child support will reduce the payment a party is required to make due to change of circumstance and an inability to pay.
When attempting to modify support you will want to make sure you know the proper procedure. In addition, it is pertinent to have documentation as proof to show your change in circumstance from the current child support order.
If you would like to hire an attorney you will want to research family law attorneys in your surrounding area. The attorney will let you know what steps are needed to take to improve your chances of the court approving a modification of child support.
