If a dad keeps kid from mom can he have cops called on him to get kid back? READ POST *posted in two groups*

My sons father is NOT on the birth certificate, there is no proof of paternity, or anything like that. If I let my son go over there and he decides to try and keep my son from me can I call the cops and get him back?

Me and my son are moving out of state October 2nd, me and my sons father were completely fine until he found out that I was leaving and now he’s threatening to take me to court for it because it’s “not fair” (I do let him see him but his girlfriend is the one that takes care of him when he’s there, and he doesn’t do anything for him financially or anything.)

He wants to keep my son for the entire month we’re going to be here, but I don’t want to do that because then my mom nor the rest of my family will be able to see him, and my son is a lot closer with them than he is with his dad. As soon as his dad said something about it my son who is five started crying and saying he wanted to stay with Mommy at home.

I compromised and told him that he could get him every Saturday night and keep him until Monday. The thing is I don’t want to do that because my son does NOT want to go there 2. I’m terrified that my sons father will try to pull something especially because he knows we’re leaving and I’m scared he’s going to try and keep my son from me. I don’t know what to do because I don’t want to keep him from his dad but I don’t trust him at all, especially recently with the way he’s been talking to me and the things he’s been threatening me with.

Also there is no proof that he’s been financially responsible for my son or anything in anyway for the last five years of his life if that means anything.

I even told him he could get our son on summer breaks, fall breaks, during Christmas break, etc. So he could still see our son but with the way he’s being I’m scared to even do that anymore.

I’m really trying to be as fair as I can given the situation but he’s making it very hard to do so.
