Wills and living trusts should be updated to reflect changes in one's life as those events occur. When the person marries, or one's spouse dies, or when there is a divorce, such events create the need to revisit one's estate planning documents to make revisions. For example, if there is a divorce but the person who made a will during the marriage forgets to go back and revise it, the divorced spouse could potentially have a continuing interest in the maker's estate under Texas law and the law of other states.
In most instances, that last scenario is the opposite of what the maker of the will wanted to see happen. Therefore, it is best to always make sure one has a good, updated set of estate planning documents in effect whenever a major life change occurs. A few other life changes that require such action are birth of a child, marriage, sale of a business, death of a child, and moving to another state.
