When putting together your Living Trust estate plan, you will be asked to name a Successor Trustee. During your lifetime, you serve as the Trustee of your own trust. You control all of your assets as usual, but should something happen to you and you are no longer able to serve (such as become incapacitated or pass away), whomever you have named as Successor Trustee will step in.
