How many hours of law school do you need to become a lawyer?

There's no set number of *hours* of law school required to become a lawyer. The requirement is to complete a Juris Doctor (J.D.) degree, which typically takes three years of full-time study. While the exact number of class hours will vary slightly between schools, it's generally in the range of 1,000-1,500 hours per year, making the total approximately 3,000-4,500 hours over the three years. However, this doesn't include time spent studying outside of class, which is considerably more.
