In Mississippi, every person eighteen years of age or over, of sound mind and memory, may by will dispose of real and personal property. Every estate in property, real, personal and otherwise, may be devised or bequeathed.

Florida law states that any will, other than a holographic or nuncupative will, executed by a nonresident of Florida, is valid as a will in this state if valid under the laws of the state or country where the testator was at the time of execution.
