In Texas, a beneficiary has a right to know what is going on with the money being held by a fiduciary. Whether the fiduciary is an executor, an administrator, or someone with a power of attorney, the right of the beneficiary to documentation is the same.
When the fiduciary fails, after proper requests, to furnish financial documents to which the beneficiary is entitled, the court can hold the fiduciary in contempt and even send him to jail.
While jail time is an extreme remedy, the court can impose it if the beneficiary is denied financial documents by the fiduciary that he is entitled to without good cause. 05-19-00327-CV.
