The answer depends on what kind of law you practice. For example, an attorney working in a corporate law firm will have different demands and billable hours than an attorney working as in-house counsel for a large corporation. But according to the 2021 Legal Trends Report, lawyers in the U.S. spend 2.5 hours each workday on billable work. Many firms also expect attorneys to reach minimum billable hour requirements ranging between 1,700 and 2,300 hours per year.
