According to Florida case law and statutory law, joinder of a spouse is not required in an interspousal conveyance of solely owned homestead property to the husband and wife as tenants by the entirety:
We hold that article X, section 4(c), does not require joinder in an interspousal conveyance of solely owned homestead property to the husband and wife as tenants by the entirety, and find that section 689.11(1) is consistent with the constitutional provision as we construe it.
And, according to Florida Statute 689.11:
(1) A conveyance of real estate, including homestead, made by one spouse to the other shall convey the legal title to the grantee spouse in all cases in which it would be effectual if the parties were not married, and the grantee need not execute the conveyance. An estate by the entirety may be created by the action of the spouse holding title:
(a) Conveying to the other by a deed in which the purpose to create the estate is stated; or
(b) Conveying to both spouses.
(2) All deeds heretofore made by a husband direct to his wife or by a wife direct to her husband are hereby validated and made as effectual to convey the title as they would have been were the parties not married;
(3) Provided, that nothing herein shall be construed as validating any deed made for the purpose, or that operates to defraud any creditor or to avoid payment of any legal debt or claim; and
(4) Provided further that this section shall not apply to any conveyance heretofore made, the validity of which shall be contested by suit commenced within 1 year of the effective date of this law.
