No, there is no visitation by default unless there is a state law to the contrary.
OK... here's the problem, if he really HAS contacted the FOC, then you need to worry that he's going to get this person on his side because you've not been "reasonable" in agreeing to something without thier mediation. SOOOO... when you contact them this week for your change of address, have the stuff explaining why you don't think he should get unsupervised visitation this summer right on the top of the things next to you. If you get a chance, say, as an aside... oh, by the way, has he contacted you fro a date for mediation of this summer's visitation, because he is telling me that your office is saying stuff that's just contrary to the decree and I can't beleive that he's telling the truth about this since you've not heard the whole story. WHat happened, when he came for Thanksgiving, he beat up our son and there were some healthcare issues because of his treatment, so I told him NO unsupervised this summer, which is what I thought I was allowed to do according to the current plan, but he is saying that someone from your office talked to him and said that he automatically gets time... which makes no sense to me. Since I've changed addresses, is it possible that he's given you information that he didn't give ot me and he got you to talk to him and give him a ruling without my input?
If you say it just like that, IF they have some wack-o employee who might have given him information over the phoen, they'll be sure to get on the stick & remind all their employees not to give a hint of what is going to happen until they're sure the whole process has been followed through... and if he is LYING about them telling him this stuff... well, now they knwo that he's lied about them saying somthign and it doesn't look good on THEM... which is usually something that people, even in a bureaucray, are most interested in making certain gets CORRECTED. officially!
