How long to file a claim against the family of the person who murder my mother . This happen in Dec 2008. There were two involved one is in prison

In Florida you generally have two years from the date of death to file a wrongful death lawsuit.  You may have waited too late to file.  I would suggest you contact an attorney immediately to see if there would be any basis to toll the statute of limitations.   Jonathan Johnson www.gawrongfuldeathlawyer.com
