Can an adult child sue for the wrongful death of a parent in Florida?

Yes. The Florida Wrongful Death Act allows a child to recover for loss of support and services, regardless of how old that child was when the parent passed away. You should consult an attorney, so that all the relevant law can be applied to the facts of your case. I know a lot of good lawyers in Florida. Shoot me an e-mail, if you need help picking one.
