Do you mean, "How do I become a lawyer in 2 years rather than 3?" or do you mean, "I have a 2-year associates degree and I want to now become a lawyer...?"
In the US, you must have an undergraduate degree, not an associates degree, to apply to and be accepted by a law school.
If you already have a bachelors and want to finish law school in two years, it is possible but highly unusual and not recommended. But, you could probably do a years worth of law school during the 2 summers you would normally spend clerking, if you can find a school that offers this.
