I have had custody of my older boys 20 and 17 almost 18 for all there lives. WE have joint custody, but I have physical custody. My 17 year old who will be a senior this fall and will be 18 in October is going to live with his dad at the end of June. I am totally okay with this. His dad thinks he should be able to claim him on his taxes this year 2007 because of the move. I am not signing custody over at all, we are just suspending or stopping any child support. It will probably be at least July before we move. Also he is trying to say that the 17 yr old has spent a bunch of time with him since January. Which is true its probably split down the middle because he works with his dad. Can he do anything about all this?? Or does it come down to him having to have physical custody in order to change things. Thanks
