In an action by a real estate broker to recover compensation for furnishing a purchaser for defendant's land, where a part of the consideration to be paid was an exchange of homestead property owned by the customer, it was error to direct a verdict for defendant, on the ground that the contract could not be specifically enforced, for the reason that the husband did not join in the contract with the wife, who owned the land, nor in the offer to convey, where there was evidence tending to show that they both executed the contract as well as the deed offered in performance, and that they were ready and willing to perform, since such question should have been submitted to the jury. Hamill v. Baumhover, 110 Iowa, 369, 81 N. W. 600.
