Are you legally separated?
You may have child support payments enforced by the court if you file with the courts that you are legally separated. The child support can be deducted just like child support ordered by a divorce decree.
The custodial parent doesn't have to file for divorce before beginning a child support case. If you and your spouse aren't ready to initiate a divorce yet, the custodial parent may file a complaint or petition with the court to establish a child support order. Your state's child support enforcement agency or local prosecutor may offer assistance with filing this complaint. Child support is not typically retroactive to the date of separation, so the earlier you file, the more money you can receive.
