How is a will revoked by law?
In most states, the probate code states that when certain events happen, a will is automatically revoked, without you having to do anything. For example, when you get married, some state laws say that any will created before you were married is considered revoked. Similarly, if you create a will that includes your spouse and you then get divorced, many state laws say that the portion of your will distributing property to your ex-spouse is revoked. In addition, when an intended beneficiary kills the will’s creator, most states do not allow the beneficiary to claim any of the property intended to be distributed to him or her by the will, and those portions of the will are automatically revoked.
