Extra expenses in addition to Child Support?

Anytime that one parent has a increase of income, the other parent has the right to file a motion in court for a increase of child support. doenting everything you provide that is NOT in a court order would be wise to do, receipts, etc..if she decide to go back to court and ask for more, you can provide the judge with doentations of providing more than what the child support payments are including health insurance if you decide to put them on your insurance plan..
