Why can't I become a solo practitioner straight out of law school (I passed the bar)?

Answer 1

Nothing is stopping you from doing that. However, the better choice would be to work for another attorney and learn the practice of law and get some experience under your belt first, and/or volunteer at your local Legal Aid Office or intern at the D.A. or Public Defender's Office or what area of law you wish to practice. You're going to make mistakes as you practice, and it's best if you have a supervising attorney show you the ropes before you go out on your own as the responsibility buck stops with your supervising attorney.
