Doctor of Law or Doctor of Laws is a degree in law. The application of the term varies from country to country, and includes degrees such as the Doctor of Juridical Science (J.S.D. or S.J.D), Doctor juris (Dr. iur. or Dr. jur.), Doctor of Philosophy (Ph.D.), Juris Doctor (J.D.), and Legum Doctor (LL.D.).
In Argentina the Doctor of Laws or Doctor of Juridical Sciences is the highest academic qualification in the field of Jurisprudence. To obtain the doctoral degree the applicant must have previously achieved, at least the undergraduate degree of Attorney. (Título de Abogado). The doctorates in Jurisprudence in Argentina might have different denominations as is described as follow:
Legum Doctor (LL.D.; Doctor of Laws in English) is a doctorate-level academic degree in law, or an honorary doctorate, depending on the jurisdiction. The double L in the abbreviation refers to the early practice in the University of Cambridge to teach both Canon Law and Civil Law, the double L indicating the plural, Doctor of both laws. This contrasts with the practice of the University of Oxford where the degree that survived from the Middle Ages is the DCL or Doctor of Civil Law (only).
Most Canadian universities that award the degree of Doctor of Laws (LL.D.) award it only as an honorary degree, but typically when awarded by a law school, it is an earned degree. Of the universities in Canada that offer earned doctorates in law, five Francophone or bilingual universities - (Université de Sherbrooke, University of Ottawa,University of Montreal,Laval University, and University of Quebec at Montreal) - offer the LL.D.
In the United Kingdom, Australia, New Zealand, and Europe, the degree is a higher doctorate usually awarded on the basis of exceptionally insightful and distinctive publications that contain significant and original contributions to the study of law. Some universities, such as the University of Oxford, award a Doctor of Civil Law degree instead. In South Africa, the LL.D. is awarded by many university law faculties as the highest degree in law, also based upon research and completion of a Ph.D. equivalent dissertation as in most European countries; see Doctor of law in South Africa. The LL.D. may also be awarded as an honorary degree based upon a person's contributions to society.
