I am the Custodial Parent, my 18 year old daughter has been living with (I have both kids) she is starting her second year of college and decided now that she wants to live on campus, hopefully using her financial aid. Since I get child support for both kids do I now have to break it out by % and give her what would be her portion of child suppport event though she wouldn't be living under my roof? I live in New York State.
