Doctor of canon law

Doctor of Canon Law (Latin: Juris Canonici Doctor; J.C.D.) is the doctoral-level terminal degree in the studies of canon law of the Roman Catholic Church. It can also be an honorary degree awarded by Anglican colleges.

It may also be abbreviated I.C.D. or dr.iur.can. (Iuris Canonici Doctor), ICDr., D.C.L., D.Cnl., D.D.C., or D.Can.L. (Doctor of Canon Law). Doctor of both laws (i.e. canon and civil) are J.U.D. (Juris Utriusque Doctor), or U.J.D. (Utriusque Juris Doctor).

A doctorate in canon law normally requires at least two years of additional study and the development and defense of an original dissertation that contributes to the development of canon law after having earned the degree Licentiate of Canon Law. Only pontifical universities and ecclesiastical faculties of canon law may grant the doctorate or licentiate in canon law.

The Licentiate of Canon Law is a three-year degree, the prerequisite for the study of which is normally the graduate level bachelor of sacred theology (S.T.B.), a master of divinity (M.Div.), a Master of Arts in Roman Catholic theology (M.A.), or a civil law degree (J.D. or LL.B.) and a bachelor degree in canon law (J.C.B.) or its relative equivalent.
