Texas Estates Code - EST § 404.001. Accounting

(a) At any time after the expiration of 15 months after the date that the court clerk first issues letters testamentary or of administration to any personal representative of an estate, any person interested in the estate may demand an accounting from the independent executor.  The independent executor shall furnish to the person or persons making the demand an exhibit in writing, sworn and subscribed by the independent executor, setting forth in detail:

(a-1) Any other interested person shall, on demand, be entitled to a copy of any exhibit or accounting that has been made by an independent executor in compliance with this section.

(b) Should the independent executor not comply with a demand for an accounting authorized by this section within 60 days after receipt of the demand, the person making the demand may compel compliance by an action in the probate court.  After a hearing, the court shall enter an order requiring the accounting to be made at such time as it considers proper under the circumstances.

(c) After an initial accounting has been given by an independent executor, any person interested in an estate may demand subsequent periodic accountings at intervals of not less than 12 months, and such subsequent demands may be enforced in the same manner as an initial demand.

(d) The right to an accounting accorded by this section is cumulative of any other remedies which persons interested in an estate may have against the independent executor of the estate.
