I have moved from Arizona to New Jersey. Do I need to have my revocable changed to the laws of New Jersey?

My general answer is going to be yes - just because I do not usually recommend revocable trusts for New Jersey residents.  It is cheaper and easier to probate.  That is not always the case in every state.  In some states it is better to use a revocable trust and avoid probate, but not in New Jersey.  Here you might be better off with a Last Will and Testament.
