Legal Question in Criminal Law in California

I'd say the best answer for this would be to contact the California Bar. You will have to do a moral qualification to be admitted, that will be the formal way of them telling you

There is no per se rule but you will have to inform the State Bar of your conviction and they will have to make a finding that you are of good moral character.

One of the requirements for admission to the bar is a showing of good character. A felony conviction is a very serious obstacle, but it won't necessarily lead the bar to reject the application. The bar will investigate both the specifics of the conviction and the way the applicant has lived his life since then. It may reject the applicant, or it may decide he has been rehabilitated and admit him. Either way, the process will probably take much longer than it does for a typical applicant.
