Don't let your son go with him if that is the case. I don't care if he has rights or not, that's child endangerment. Period. My ex-husband would do that when he would get our daughter on Fridays. He would be with her for an hour, maybe 2, then drop her off at his sister's house for the night. As soon as i found out, when i would call to check up on her, i would just go pick her up and take her home. Then i would pull up to the party he was at and let him know that he wouldn't be seeing her for quite some time until he can do what he's supposed to do as a dad. He didn't care so i just did it myself with my Mom's help, i had moved back in with Mom when we split. It is hard, but some sacrifices have to be made that are in the best interest of the child.
