Tex. Prop. Code § 82.115

A third person dealing with an association in the association's capacity as a trustee may assume without inquiry the existence of trust powers and their proper exercise by the association. A third person who lacks actual knowledge that an association is exceeding or improperly exercising its powers is fully protected in dealing with the association as if the association possessed and properly exercised the powers it purports to exercise. A third person is not bound to ensure the proper application of trust assets paid or delivered to an association in its capacity as trustee.
