The effect of a divorce on the legality or sufficiency of a will depends on your state’s law. In some states, a divorce decree will automatically revoke your entire will. In other states, a divorce will only revoke the provisions that would distribute assets to your former spouse, not the will itself. In either case, should you experience a divorce, you should review the property arrangements in your will. This is also true of other important documents, such as life insurance policies and bank accounts. This is such a fundamental principle that divorce courts frequently require litigants to address these issues as part of divorce decrees.
