Many people " Domicile " in states that they do not visit for years and years . We claimed domicile in Florida for thirteen years . Foreign service people , military ,travelers . Do ya need to prove anything , in Florida you do not . Go to any courthouse and file a " Proclamation Of Domicile ", you are done . But lets assume that you will want a drivers license and registration of autos , get one ! It is a separate action and they do not have a whole lot to do with domicile . Matter of fact why would you want a domicile , what you might want is a address for documents , forget domicile , get an address for all your needs . Do not confuse " domicile " with what you need/want !
