My response:
I would strongly suggest that your "friend" read and understand F.S. 415.40, et seq. - - the Florida "Elder Abuse" statutes (which include "financial" abuse). To misunderstand, or to understate the gravity of Elder Abuse would be a grave mistake. If I was a long lost family member, "coming out of the woodwork" as it were, I'd go after your "friend" with a vengeance.
Suffice it to say, I would not want to be on the "receiving end" of an Elder Abuse civil lawsuit, or criminal prosecution. In summary, I find nothing I can disagree with from our other, esteemed, contributors in this thread thus far.
