The trustee has no right to keep you from seeing documentation or asking for an accounting regarding this irrevocable trust. You need to immediately consider filing a complaint against the trustee in court to remove him as trustee. He has a fiduciary (think money) obligation to you by statute. If he doesn't meet those obligations, is wasting assets, hiding assets, funneling monies and so on, he will be personally obligated to you should you see him.
