Locke Lord LLP is an American law firm of approximately 1,000 lawyers with 19 domestic and four overseas offices. Locke Lord is consistently voted as one of the top 100 most prestigious law firms in the world by Vault and American Lawyer. Locke Lord was formed on October 2, 2007, after the combination of Texas-based Locke Liddell & Sapp PLLC and Lord Bissell & Brook LLP, a national law firm headquartered in Chicago. The firm changed its name from Locke Lord Bissell & Liddell LLP to Locke Lord LLP on September 27, 2011. On January 10, 2015, the merger between Locke Lord and Edwards Wildman Palmer was completed. The merged firm adopted the name Locke Lord, although legacy offices of Edwards Wildman Palmer used the name Locke Lord Edwards for a transition period. The oldest component of Locke Lord traces back through the legacy Locke Liddell & Sapp side to a firm founded in Dallas, Texas by Maurice Locke in 1891. It is the second oldest continuously operating firm in Dallas. The firm became Locke & Locke when Maurice Lockes sons ran the practice, and his grandsons renamed it Locke Purnell. In 1916, another predecessor firm, Huggins & Kayser, began developing independently in Houston, Texas. Frank Liddell, known as an outstanding trial lawyer, became a partner in the Houston-based Huggins & Kayser firm in 1921. Charles Sapp then joined the predecessor Houston firm in 1946. Back in Dallas, six young attorneys spun out of the oldest firm in Dallas and formed another predecessor firm in 1965 under the name Rain Harrell & Emery. In 1987, Maurice Locke’s original Dallas firm and the newer Rain Harrell Emery Young & Doke firm merged to create one of the then-largest law firms in the Southwest: Locke Purnell Rain Harrell. In 1999, the Dallas firm Locke Purnell Rain Harrell merged with the Houston firm of Liddell Sapp Zivley Hill & LaBoon to form Locke Liddell & Sapp. At the time, this was the largest law firm merger in United States legal history. Locke Liddell & Sapp continued to exist until the 2007 national merger with Chicago-based Lord Bissell & Brook.
