One Denver realty company is accusing another of stealing its commission following the sale of a $7.3 million mansion south of the city. The dispute has its origins in 2018, when the real estate agent Christy Owen of Kentwood Real Estate helped McKay and Nina Belk buy a $2.1 million home in Cherry Creek. McKay Belk is an heir to and the former president of Belk department stores, which is based in North Carolina, and a former Coca-Cola board member.
