The Basics About a Law Degree
The Bachelor of Laws (LL.B., LLB.) is an undergraduate, or bachelor, degree in law awarded in Canada to provide a scholarly education, and therefore requires additional education or training before a graduate is authorized to practice law. It is sometimes referred to as graduate degree because previous university education is usually required for admission. In the US, the Doctor of Law (J.D) degree is the required degree for the practice of law.
