Which of the following methods allows a testator to revoke a will in Delaware?

In Delaware, a testator can revoke a will through the process of canceling the will or by executing a new will. This is a formal and clear method of revocation recognized by the law. The act of canceling typically involves physically destroying the original document, such as tearing it up or marking it out, which indicates the testator's intent to revoke it. Alternatively, a new will can include explicit language stating that it revokes any prior wills, making the testator's intent unambiguous.

This method is aligned with the legal standards for revoking wills, focusing on an affirmative action by the testator to show a clear intent to revoke the previous will. In contrast, sending a letter to the court may not effectively communicate this intent, as wills need to adhere to specific legal formalities to be valid or revoked. Similarly, having a witness destroy the will can complicate matters legally and does not reflect the direct intent of the testator. Lastly, making verbal declarations to family members does not provide the necessary legal certainty required for revocation, as verbal statements lack the formal recognition that written documents necessitate in estate planning.

Using cancellation or a new will ensures that the testator's testamentary desires are properly documented and respected according
