If you are a current beneficiary of the trust you can demand an annual accounting from the trustee. If you are not a current beneficiary of the trust you may not be able to get an accounting. Bottom line is that you cannot do anything without being represented by an experienced probate/trust lawyer. You might try the Houston Bar Association for a referral to a lawyer who would consider pro bono representation after it is determined that you qualify.

Attorney Paxton has provided you with a solid answer. Please bring this matter to the attention of the probate court, which has the power to order an accounting. Good luck to you.
