Sotheby’s International Realty, founded in 1976, is a luxury real estate brand that offers a collection of luxury homes, estates and properties for sale throughout the world. It is owned by parent company Realogy, which was spun off in July 2006 from former parent company Cendant. Sotheby’s has real estate offices located around the world with over 500 offices and 11,000 sales consultants.
In March 2010, it was announced that Sotheby’s International Realty Affiliates LLC has agreed an exclusive 25-year licensing agreement for the United Kingdom with Countrywide plc, the UK’s largest estate agency group and provider of related property services. This license grants Countrywide exclusivity to the Sotheby's International Realty brand throughout the UK and Channel Islands, leading to the creation of a new subsidiary called United Kingdom Sotheby’s International Realty.
