delivered the opinion of the court.
This is an action instituted in a justice court. There are no pleadings. The case comes here from the county court of the City and County of Denver where, on appeal from the justice court and upon a trial to the court without a jury, there was a judgment for defendant. Plaintiff below has sued out this writ of error.
From the evidence, as the same is set forth in the abstract, it appears that plaintiff seeks to recover from defendant the sum of $200. This amount the defendant had received from a prospective purchaser of plaintiff’s property, consisting of a house and some furniture. Defendant is a real estate agent. Plaintiff listed his property with defendant for sale. Defendant claims that he received a deposit of $200 from a prospective purchaser, that $1 thereof was paid to plaintiff, and that he, defendant, retained $199 as his commission. The sale price of the property was $3,350. The theory of the plaintiff appears to be that defendant never earned a commission. The assignments of error all go to the proposition that the judgment, which was for defendant, is against the law and the evidence.
The defendant entered into a written contract with the *180prospective purchaser. The contract was signed by such purchaser on the one part, and by the defendant, in his own name as agent, on the other. Plaintiff claims that this contract is void, under Castner v. Richardson, 18 Colo. 496, 33 Pac. 163, because the agent had no written authority to execute a contract to sell real estate, and there was no ratification in writing. This point is not necessarily material, since this is not an action to enforce the contract.
The defendant did more than make a contract which plaintiff now says is void for reasons above indicated. He brought plaintiff and the prospective purchaser together. Plaintiff learned of the contract, and there is evidence that he then said to defendant:
“I accept the contract, and I congratulate you on your quick sale and your good judgment.”
The terms of the contract were satisfactory to plaintiff. He could have ratified the contract in writing, or otherwise made it binding on himself. At any rate the prospective purchaser was willing to sign, and did sign, a contract containing terms satisfactory to plaintiff, the defendant’s principal. The contract contained agreements on the part of plaintiff as well a's agreements by the purchaser. The sale was never completed, but that fact alone does not defeat the defendant agent’s right to compensation. It may have been the plaintiff’s fault, or, both plaintiff and the purchaser may have abandoned further negotiations.
The bill of exceptions shows that the trial court was influenced, in part, by the following paragraph in Finnerty v. Fritz, 5 Colo. 174:
“But where an agent has produced a purchaser who is acceptable to the owner, and able and willing to purchase on terms satisfactory to the owner, he has performed his duty, and if from any failure of the owner to enter into a binding contract or to enforce a contract against the purchaser, the sale is not completed, the agent may recover his commissions.”
This principle was approved in Perkins v. Russell, 56 Colo. 120, 137 Pac. 907. There is some evidence here to *181bring the case within that rule. There is no evidence that plaintiff’s failure to complete a sale with the prospective purchaser found by defendant was due to any fault of defendant.
The plaintiff having brought the case here, has the burden of showing error. Denver Dry Goods Co. v. Jester, 60 Colo. 290, 152 Pac. 903, L. R. A. 1917A, 957. In our opinion, he has failed in that regard, and not shown that under no tenable theory could the judgment be proper. The judgment is therefore affirmed.
Mr. Chief Justice Teller and Mr. Justice Burke concur.
