You need to have each of the beneficiaries sign a "receipt and release." This is a legal document which states that the beneficiaries received certain assets and are releasing the trustee from responsibility. That would probably be the only way to achieve finality.
In order to fully protect yourself, you should hire a Florida lawyer who is experienced in trust law. This is not a "do it yourself" project.
I'm not a Florida lawyer, and am just answering this on "general principles." This is neither an opinion nor does it create any attorney-client relationship.
