(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.
