If broker who acted as agent for both parties to a real estate exchange transaction was a party to, or had notice of the fraud that induced the consummation of the transaction, he is in no position to assert lien for commissions on one of the tracts of land conveyed, reserved in the deed, after the transaction had been rescinded because of such fraud, though rescission did not specifically provide for the cancellation of commission notes. Speer v. Dalrymple, 222 S. W. 174, - Tex. Civ. App. - .

If broker who had acted as agent for both parties to real estate exchange transaction was a party to or consented to rescission of transaction on the ground that it had been induced by fraud, he could not enforce the lien on land of defrauded party reserved in the deed by which the land was conveyed.
