No, unfortunately, while that law would be nice, that law does not exist. You will need to go back to court and show the court that your child is not in daycare so that should not be a part of your child support payment. You would file a Motion to Modify to accomplish this.
If you have an order that is signed and dated by a Judge that has modified your decree, and the state continues to take money above and beyond that order, then you would need to file a Motion to Return Overpayment. You also may be able to talk to the Friends of the Court office working with your file (if they are working on your case), as they may be able to help.
