My brother (I know ) forged (I have documents) my mother's signature years ago and took a loan on her house. Didn’t pay loan, house foreclosed on.
Long story, many more horrible details of her being taken advantage of and mistreated but seems brother also has taken her bank accounts,
stocks,
pension,
and spent on himself, girlfriend and son.
Have some documents verifying
Good luck. Hope you update us.
You need to find the court that serves the area in which your mother lived, and where residence was established, at the time the alleged guardianship took place. It might have been through a Circuit Court, or a Probate Court, which handles estate matters.
Best source might be to locate the Florida State Bar, familiarize yourself with the levels of court, then do some research to find out which level would handle guardianship.
Some courts have online listings of civil matters, so you could then search by your mother's name to try to locate a guardianship file. If Florida courts are open and staffed, a staffer could help you.
You can also search for Florida statutes on guardianship, and although statutes aren't easy to read, you hopefully could find something addressing the necessary steps to get guardianship, as well as the level of courts in which guardianships are handled.
To prove the elderly financial abuse, you will need documentation, and the assistance of an attorney. That's another avenue, depending on your own financial situation: hire an elder law or estate planning attorney, either of which should have litigation experience.
