Law school lasts 3 years, after which you can specialize and decide what type of lawyer you want to be.
The ones that represent people in front of a judge are typically called trial lawyers.
Oftentimes, it takes several years of preparation and training even after law school - at a minimum - to be able to argue cases in front of a judge (depending on where you are located).
