Fla. Stat. § 732.609

Property that a testator gave to a person in the testator’s lifetime is treated as a satisfaction of a devise to that person, in whole or in part, only if the will provides for deduction of the lifetime gift, the testator declares in a contemporaneous writing that the gift is to be deducted from the devise or is in satisfaction of the devise, or the devisee acknowledges in writing that the gift is in satisfaction. For purposes of part satisfaction, property given during the testator’s lifetime is valued at the time the devisee came into possession or enjoyment of the property or at the time of the death of the testator, whichever occurs first.
