The rights of a surviving spouse to an elective share, intestate share, pretermitted share, homestead, exempt property, family allowance, and preference in appointment as personal representative of an intestate estate or any of those rights, may be waived, wholly or partly, before or after marriage, by a written contract, agreement, or waiver, signed by the waiving party in the presence of two subscribing witnesses.
The requirement of witnesses shall be applicable only to contracts, agreements, or waivers signed by Florida residents. Any contract, agreement, or waiver executed by a nonresident of Florida is valid in this state if valid when executed under the laws of the state or country where it was executed, whether or not he or she is a Florida resident at the time of death.
Each spouse shall make a fair disclosure to the other of that spouse’s estate if the agreement, contract, or waiver is executed after marriage. No disclosure shall be required for an agreement, contract, or waiver executed before marriage.
No consideration other than the execution of the agreement, contract, or waiver shall be necessary to its validity, whether executed before or after marriage.
