In a joint will contract, a breach by one party may lead to probate according to the later will.

• A. Probate according to the later will
• B. Constructive trust for the first will beneficiary
• C. Rescission of the contract
• D. No remedy

Answer: (A)

A joint will contract creates a promise between parties about how property will pass after death, and a breach by one party invites enforcement to carry out that promised disposition. If one side breaches by revoking or altering their will contrary to the agreement, the other side’s heirs can be protected by having probate proceed under the terms of the later will. In essence, the court uses the later will to honor the contract and ensure the intended distribution happens, rather than letting the breach derail the arrangement.

This is why probate according to the later will is the best answer. It directly implements the contract's typical aim—to keep the agreed-upon disposition intact even if one party tries to back out. A constructive trust would be an unrelated equitable remedy not necessary here, rescission would undo the contract instead of enforcing it, and no remedy would ignore the breach, which the law aims to prevent.
