Fla. Stat. § 689.05

All declarations and creations of trust and confidence of or in any messuages, lands, tenements or hereditaments shall be manifested and proved by some writing, signed by the party authorized by law to declare or create such trust or confidence, or by the party’s last will and testament, or else they shall be utterly void and of none effect; provided, always, that where any conveyance shall be made of any lands, messuages or tenements by which a trust or confidence shall or may arise or result by the implication or construction of law, or be transferred or extinguished by the act and operation of law, then, and in every such case, such trust or confidence shall be of the like force and effect as the same would have been if this section had not been made, anything herein contained to the contrary in anywise notwithstanding.
