Custody/Visitation Issues please help!?

You need to check into things a bit more and maybe change lawyers. You have sole custody I take it? If her father is going to be gone during his time and leaves her with an unapproved person...then I would think the child would not have to go. The girlfriend is not a legal guardian so she can not legally be watching the child for a few weeks like that without prior permission from the mother and father to do any medical things or even anything else that needs done. I had a problelm where my ex had a girlfriend who would take my kids on his weekend. He had not known her long. The kids barely knew her too. When I found out from the kids that they had gone with her to a town a couple hours away because dad had to work, I was furious. When I saw him again, I told him that in no certain terms the woman who was his girlfriend was to have my kids and take them somewhere without my knowing. If he had asked me before this I would have worked something out. His weekend with the kids he had to work, and I could have had them with me at least while he was at work instead of a total stranger. I told him I did not want her taking my kids places. ONLY his family--siblings and parents were mentioned by the judge as okay to transport my kids if we had to work out something else. Until you ex marries a woman who becomes the step mom....no one should be taking care of your child without your consent.
