The primary cost of law school is the time. It will take three years to earn either an LL.B. (Bachelor of Laws) of J.D. (Juris Doctor) degree.
It might be wise to consider getting two degrees out of the time you invest in law school. These joint degree programs might be joint law (for example joint civil/common) or joint law and something else.
Whether you do these degrees or not, it would be a mistake to consider law school without considering these opportunities.
Some examples worth considering:
Joint Law – U.S. – Canada
Windsor – Detroit LL.B./J.D.
Ottawa – Michigan State LL.B./J.D.
Ottawa – American University LL.B/J.D.
Osgoode – NYU LL.B./J.D.
It is important to note that in each of these opportunities, you will earn both a Canadian LL.B. and a U.S. ABA approved U.S. J.D. degree.
For the distinction between the LL.B. and J.D. degrees see:
Joint Law – Civil/Common
Both the University of Ottawa and McGill have three year programs that allow you to earn both a Civil (Quebec and Louisiana) and Common law degree. It is worth noting that the Civil law system is more prevalent than the common law system.
Law And Something Else:
There are many examples. One of my favorite is the Joint LL.B./MBA degree that offered by the Western Law School and Ivey School of Business. Incredibly, this degree can be achieved in three years.
