In a word, yes.  California Law allows parties to file a “Petitioner to remove a trustee” if they are not following the directions of the trust.  A trust is a plan (hence the term “estate plan”) for the person putting money into the trust, called the “settlor”.  A trustee has a “fiduciary” duty, meaning a heightened to duty of good-faith and fair dealing.  An attorney can have a trustee removed and another appointed by filing such an action.
