In Brazil, the Doctor of Laws degree, known in Portuguese as Doutor em Direito or Doutor em Ciências Jurídicas, is the highest academic degree in law available.

In some of the country's most important universities there is a higher title known as livre docência, like the habilitation in some European countries. However, this higher title is not a degree in the strict sense, because livre docência nowadays is an internal title, that applies solely within the institution granting it.

In the past, livre docência was a degree in the fullness of the term, and a professor bearing the title would enjoy the privileges of livre docência if he transferred from one institution to another; there are still living professors who hold the "old" livre docência degrees; but all new titles of that name only confer privileges within the institution granting it.

The doctoral degree is awarded upon the completion and the successful defense of a thesis prepared by the doctoral candidate under the supervision of a tutor. The thesis must be examined by a board of five professors, holders of the title of doctor or of a livre docência. Two of the members of the board must be professors from another institution. In most Brazilian Law Schools, the candidates are also required to earn a minimum number of credits.
