Thanks to each of you for your input. I do not believe there is anything mentioned about moving in any of the paperwork. I can't imagine that anyone would have to stay put when their adult child still has some visitation.
Knowing Chuck - he will still assume it is all about him but in fact - my move is all about me AND Ryan.
I retired last year although I hadn't really expected to quite so soon. I spend more time at my cottage in the nice months than I do at home. My cottage is not handicapped accessible and unsuitable for Ryan. It is also becoming more and more difficult to maintain 2 homes. So I've decided to buy (or build) a home for myself, Ryan and a live-in nurse/caregiver on the lake here. Josh wants to buy the house with me and we've been looking/planning for a couple of months. The move won't take place for another year or possibly more so we still have time to work out all the details. But the decision is made.
My sister works for a family law lawyer so I'm sure she can ask the question. I do find it important to hear what others have experienced with regard to long distance visitation.
