You just have to have an undergraduate degree to apply for law school. It take three years to get your doctorate if you go full time, or four if you go part time. I do not think it's a good investment unless (1) you have rich parents who pay for your tuition and books; or (2) you get some type of grant or scholarship. Otherwise, you're going to come out of law school with around 100k in student loans, and the chances of finding a high paying job like mine in a big law firm are slim. Most lawyers make much less, around $60k per year. Just do your research before you apply. :) Good luck with the decision!
