The Department of Law is responsible for providing legal counsel and representation for the City of Chicago, and the departments, officers, and employees of the City.

The Law Department serves the Mayor, the City Departments, Boards and Commissions and the City Council as they establish and administer policies and programs to benefit the Chicago residents. The Law Department’s clients are the City’s more than forty Departments, as well as its agencies and officials. The Department employs approximately 280 lawyers that handle litigation, transactional, and legislative projects, and enforce the Municipal Code.

Few law offices can match the breadth of our practice.  We litigate cases in every federal, state, and administrative courtroom in the City.  Our transactional lawyers routinely work in conjunction with colleagues in the Department’s legislative section on complex deals involving large-scale public projects.  Our service takes many forms, from helping communities through effective ordinance preparation and enforcement, to providing City departments with legal advice.

The Law Department is committed to the goals of the City, and its programs and services through work involving communities, the environment and economic development. Law Department attorneys have unparalleled opportunities to take responsibility for important cases, to learn a variety of legal areas, and to play a role in visible issues that have an impact on public policy.
