Legal Question in Wills and Trusts in California

Re: CA laws governing executors

In most circumstances, none. Because the trust can still be revoked, the settlors retain the right to keep the trust private.

From a practical standpoint, I suggest you speak to the settlors. You can always say that you are uncomfortable accepting this responsibility without knowing what you are getting into. The settlors might let you see the trust, because they want to know whether or not you will serve. If you will not be able to serve, then they might want to pick someone else. Perhaps they will agree to let you see the trust.
