The Firm dates of 1902, when Mr. Francisco Pérez de la Cruz opened his law offices in Malaga. He chaired the Malaga Bar Association between 1928 and 1932. The Firm’s initial focus on Private Law (contracts, real estate, family relations and inheritance) was continued by Antonio Pérez de la Cruz González, who chaired the Malaga Province Administration.
