Leong & Wong is a civil litigation-based law firm that was formed in January 2017 in Kota Kinabalu.  The firm was founded by two lawyers in one of the largest firms in Sabah who decided to team up and take on the challenge of setting up a firm together. They believe that a leaner, more agile organization will allow them to further hone their skills in a more effective environment.

While the firm remains focused on civil litigation as its core practice, it also delves into other non-litigation matters.  The firm strives to maintain an efficient business operation capable of providing consistent, high quality service to its clients.  At the same time, the firm will continue to observe the high ethical standards expected of the legal profession.

Given the background expertise of its lawyers, the firm aims to add value to its clients and assist in meeting any legal challenges they may face.
