My husband and his first wife were divorced in NY, and the Child Support Order was issued by the Court in Suffolk County, NY. Approximately two years ago, my husband allowed his ex-wife to move with the child to MD where they still reside. My husband and I have now moved to FL. We are wondering if the Child Support Order can now be modified (as to the calculation of the amount) to adhere to the formula that MD or FL uses which is almost certainly more favorable to the obligor than that of NY (17% of the obligor's gross income for one child). If so, where would the Petition be filed? Must it be filed in NY?
