I concur in the result. I do not think that the courts will enforce a contract whereby a party deprives himself of all power to bequeath or devise by will the property of which he is the owner at death, except in cases of adoption, where the contract is made for the benefit of an infant, and not to the exclusion of children. It will certainly not do so in a case where the agreement is unilateral, and where it may be terminated by the other party at will.
