I tell my clients that they only need to update a will or a trust when something fundamental changes in their life or if they don’t want the executor to be the executor anymore. The same applies to a trust. In the trust, the executor position is called a successor trustee. If you don’t want that person, you need to change it. You also need to change the trust to add or remove beneficiaries. But for the most part, that’s it for changing your beneficiaries and who’s going to manage your estate. You must change a will or create an amendment to a trust if there’s a change in your life or preferences.
