When my daughter goes away to college, can I send the child support payment directly to her?

Hi -- the short answer to this question is:  no, you must continue to give the money to her mother.   The support is intended to provide for her shelter and other expenses when she returns home from school as well -- during breaks and vacations -- so, the money must be provided to her mother to pay expenses in her absence.   The question is:   are you also paying your daughter's room and board while she is away at school?   If so, it would have been expected that you would have received some proportional reduction in your child support so that you weren't, in effect, paying housing expenses in two places.   However, if your agreement has no provision for a reduction, I'm fairly certain that's not going to happen.   Good luck!
