The Master of Laws is an academic degree, pursued by those either holding an undergraduate academic law degree, a professional law degree, or an undergraduate degree in a related subject. In some jurisdictions the "Master of Laws" is the basic professional degree for admission into legal practice. It is commonly abbreviated LL.M., from the Latin Legum Magister (meaning "master of laws").
To become a lawyer and practice law in most states and countries, a person must first obtain a law degree. While in most common law countries a Bachelor of Laws (or LL.B.) is required, the U.S. and Canada generally require a professional doctorate, or Juris Doctor, to practice law .
The Juris Doctor (J.D.) is a professional doctorate and first professional graduate degree in law. The degree is earned by completing law school in the United States, Canada, Australia, and other common law countries. Many who hold the degree of Juris Doctor are professionals committed to the practice of law, and may choose to focus their practice on criminal law, tort, family law, corporate law, and/or a wide range of other areas.
