The mission of the Law Students Association (LSA), UC Davis School of Law's student government, is to increase the value of the legal education offered at King Hall. LSA works toward improving student life, addressing student concerns, and acting as a liaison among the students and the faculty, administration, and alumni. The LSA President meets frequently with various members of the King Hall community to communicate and advocate for the interests of the student body. The LSA manages a budget of over $30,000, approving appropriations to approximately fifty student organizations. The LSA's appropriations contribute to funding nearly all student organization culture weeks, lunchtime speakers, and special annual events.

The fourteen-member LSA Board includes the President, Vice President, External Vice President, Treasurer, Secretary, two Representatives from each of the three classes, three 1L Section Representatives, and one LL.M. Representative. In the fall semester, 1Ls vote for five of their peers to serve as 1L Representatives and Section Representatives. The entire student body votes for 1L candidates for LSA Secretary. The student body elects the remaining officers in elections late in the spring semester. Other elected and appointed student representatives serve on committees dealing with student recruitment, retention, and outreach; educational policy; student health insurance; alumni relations; and career services. LSA Board meetings, held every two weeks, are open to the entire King Hall community.

In 2013, the LSA Board created the Student Budget Policy Committee to collect information on the total cost of attending King Hall and law school expenditures. The Committee is comprised of two members from the 1L class, three members from the 2L class, and two members from the 3L class; the LSA President also sits on the committee in a non-voting capacity. 

The LSA is also responsible for many student social events and fundraisers. In the fall, the 1L Representatives coordinate, in conjunction with the Graduate School of Management, School of Medicine, and School of Veterinary Medicine, the UC Davis Graduate Student Mixer. The 3L Representatives fundraise for their class gift and work with the administration to plan Commencement.
