Join the ILA

Membership of the ILA is open to anyone interested in international law. The majority of Members join through the various regional branches. If no branch exists in the relevant region, individuals are welcome to apply for membership of Headquarters Branch.

Most ILA Branches hold their own events locally and several have their own committees which study topics in parallel with the ILA International Committees.

Branches may nominate individual members to sit on the ILA International Committees. Appointments are made by the Executive Council on the advice of the Committee Chairs and the Director of Studies.
