I am not sure that even an attorney known as 'the Bull' can do very much to make your situation better. This is why...
You signed the car's title over to your sister -- so, unless you have a
document stating that this was a temporary arrangement and/or some
witnesses -- I can't see where you have much hope of getting the car
back from your sister.
Similarly, regarding the antiques, do you have any witnesses or
anything in writing which indicates that your sister agreed to return
them to your possession
at some future point? If not, you face an
up-hill battle at best.
You mention that this arrangement with your sister was in response to
some sort of domestic dispute (I assume with a spouse). It sounds
like your purpose in doing this may have been to hide assets until
after a divorce proceeding was concluded.
While I can sympathize with your situation -- my gut tells me that what
you did is probably illegal. If that is the case -- trying to
remedy the situation with your sister -- besides being more than likely
unsuccessful -- may actually serve to get you in legal trouble over the
I am not an attorney -- the general advice I have given you is based on
life-experience and on my experience as a counselor. I strongly
advise you to consult a Florida attorney -- to verify the accuracy and
completeness of the advice I have given you here.
Many attorneys will consult over the telephone and most attorneys do not charge for a first-consultation.
