(a) A court that authorizes payment of estimated quarterly compensation under Section 1155.006(a) may later reduce or eliminate the guardian's compensation if, on review of an annual or final accounting or otherwise, the court finds that the guardian:
(1) received compensation in excess of the amount permitted under this subchapter;
(2) has not adequately performed the duties required of a guardian under this title; or
(3) has been removed for cause.
(b) If a court reduces or eliminates a guardian's compensation as provided by Subsection (a), the guardian and the surety on the guardian's bond are liable to the guardianship estate for any excess compensation received.
