The order is still valid. Unless or until its changed, it can be enforced.
And that is the key to this problem...it goes back to the original order.
So the start to unravel this mess is to pull out a copy of the order. IF you do not have a copy? Then you would want to contact the clerk of the court and they can provide you a copy.
Here is the contact info
(sorry for the delay...took awhile to get this address)
Now, on to your question....once you get the order, you can require him to comply with it. He has to follow the court order. From what you describe, it sounds as though he is not following the order. Your recourse to require him to follow the order, is to take him back to court.
The problem you have is that the OR court retains jurisdiction...you have to go to OR to resolve this.
SO, he refuses to take the child? You want him to? You need to go to the OR court and the court will order he take the child. Of course, if he has not seen the child in a few years, that can be grounds to modify the order...heck, you may be able to give him even less time with the child.
As for him stopping your move? Doubt it...not with what you describe...not with the games he is playing and his lack of contact with the child.
IF he wants to try and take the child from you or stop your move, he needs to hire a lawyer and ask the court to intervene...of course, you can have a lawyer present your side of the case...what you describe? He would not win.
It may cost you some money (of course it will cost him as well)...but you will be able to move.
