The Private International Law Association was formed as an academic organization on November 4, 1949 for the purpose of "enhancement of the study of private international law and promotion of cooperation with similar academic bodies overseas, as well as coordination among researchers of private international law" (Association Charter, art. 3). Thus, the Association consists of regular members who "are engaged in the study of private international law or its related subjects" (Charter, art. 5(1)). Moreover though, the Association is not limited to persons associated with educational research organizations such as universities and in fact includes many persons from the legal world such as practicing attorneys.

The Association's executive decision-making organization is the Board of Councilors. The Board consists of eighteen (18) members-the President and seventeen (17) Councilors-who execute the Association's work. The Association's audit is done by two Auditors selected from the Association's General Members. Further, an Internet Management Committee is assigned to administer this web site.
