Such as, if they can(t) move out of state and moooore?
If i'm correct, i think that after they have been evaluated multiple times and had surprise visits from the custody people, and are granted full custody. Then they could move i thinnk. Because the people won't have to check up on them or anything.
Check on a local lawyer. That would be hard to answer here. You can also post your questions here http://funadvice.com/r/1630q50018h
Kayla that depends on the state they are living. Grandparents and custody laws differ state to state.
