A broker was employed to procure a purchaser of real estate; he procured a purchaser who contracted for the purchase thereof; the owner executed a warranty deed conveying the premises to the purchaser; the deed was not delivered and the purchase price paid over, because of the refusal of the owner to pay the cost of sewer tax bills which would be subsequently issued, the construction of the sewer being in progress during the transactions; the attorney of the broker erroneously advised that the owner was liable for the tax bills. Held, that the broker was not entitled to commissions. Mercantile Trust Co. v. Niggeman, 119 Mo. App. 56, 96 S. W. 293.
