You will have to bring a legal action (lawsuit against the trust) in county court (typically, in the part or department of county court called the "chancery court" or "chancery division") in which you seek to have the court enforce the "not needed" terms of the trust and dissolve it, releasing the money to you. In the course of the lawsuit, the court will likely appoint a new trustee (even if only on a temporary basis) to represent the trust's interests. This kind of legal action can be challenging for non-lawyers--it is much more complex than, say, a small claims court. You are advised to retain an attorney to help you.
