You did not say whether dad had filed a petition for modification in court or simply asked you for child support. Until a court says otherwise, he owes you child support and modification cannot be retroactive. This means that unless and until he files a petition for modification, he still owes you support even though the child is living with him. Once he files a petition for modification, he will have to first prove that a change of primary residence is needed and in the childs best interest, not simply because the child wants to live with him. Then support would be calculated and will take into account your income, dads income, and the time sharing schedule.
