It’s a good idea to review your living trust, and all your other estate planning documents, at least once a year. As a general rule, you should change your trust at any time it’s no longer what you want. Any major changes in your family, such as marriage, divorce, death, birth, etc., could justify a change in your trust. If the person you’ve named as your successor trustee can no longer fulfill the responsibility, you should make changes accordingly. You retain the power to make changes at any time to your revocable living trust by simply amending your trust.
