If Alice and Bob enter into a contract that calls for Bob to put a provision in his will that benefits Alice, and Bob does not put in the provision, would the courts likely uphold the contract after Bob's death, and give Alice the benefit, assuming all other aspects of the contract were legal and complied with?
I'm imagining cases like: Alice provides end-of-life care for Bob in exchange for an inheritance. Or in a slow real estate market, Alice agrees to sell a property at a reduced price that she jointly owns with Bob, in exchange for an inheritance.
