If your child enlists in the military and is no longer living with your ex then there would not be any reason to pay child support because he would no longer be supporting his child either. But you would have to get your child support order modified I'm sure otherwise the garnishment would just continue on and on. Once an order is in place you are lost in the crowd until something is filed to change it. And unless your son needed some support other than what the military would provide.....why would you need to send money directly to him? Child support is child support and when the child is no longer being supported by either parent it should stop. I would suggest being ready for the change though and have a motion to modify child support ready to be filed as soon as he goes in. Your ex shouldn't still be receiving money for a child that doesn't live with him. If you even let it go one month past you will just be giving him your money. I would start talking with an attorney now and be prepared.

If your child goes into the military you are no longer required to pay child support.

If not then once your child turns 18 you will no longer be required to pay child support.

What about if he goes away to college and not in the military? He won't be domiciled anywhere. Should I still have to pay till he is 18 when he lives at a dorm?
