delivered the opinion of the court.
*5272. Brokers—what constitutes release of vendor from, liability for commissions. Where one who has been negotiating the sale of property for the vendor executes an instrument, after a contract for the sale of the property has been entered into and he has received a sum of money from the purchaser’s agent, which recites that he thereby releases his “right from commission on” the property in question, such instrument constitutes a release of his claim against the vendor for commissions.
