474.120. Inheritance and statutory rights deemed waived, when. — The rights of inheritance or any other statutory rights of a surviving spouse of a decedent who dies intestate shall be deemed to have been waived if prior to, or after, the marriage such intended spouse or spouse by a written contract did agree to waive such rights, after full disclosure of the nature and extent thereof, including the nature and extent of all property interests of the parties, and if the thing or promise given to the waiving party is a fair consideration under all the circumstances.

(1964) Where husband and wife had entered antenuptial contract by which each agreed not to share in the other's estate and waived all interest or claims of every kind and nature and all marital, statutory, and dower rights and allowances as surviving spouse, widower was barred from claiming homestead and family support allowance as well as other participation in wife's estate, except as authorized by the contract.

(1968) Anticipatory, preparatory, collateral, and ancillary acts performed in reliance on a verbal contract, generally are not sufficient part performance to call for an exception to the provisions of the statute of frauds; but if the verbal agreement is sufficiently established, the acts are done with the knowledge of the other party, and if the changes in circumstances resulting from such acts are of such nature that the consequences thereof are, or may be, disastrous, the court may enforce the contract, even though the acts are not, strictly speaking, in execution of the contract.
