Thanks. This confirms what I was able to get from Chapter 203. I didn't know if MA adopted a uniform code. You're right about parents setting up a living trust, then wanting to add an adult child as an authorized signer without the proper authorization in the trust. Actually, we see very few new irrevocable trusts, but are beginning to grapple more and more with grantor trusts in which the grantor is now deceased, and the successor trustee is not very knowledgeable.
