The international relations of advocates are primarily contacts between law firms and single advocates. An advocate will only in very exceptional cases advise on issues concerning foreign law. Several Finnish law firms, however, are members of corresponding international groups. A few firms have subsidiaries abroad.

The international contacts of the Bar Association started in the 1930's with the Scandinavian Bar Associations, and this co-operation continues to be strong and lively. The Bar Association is a member of the IBA (International Bar Association) and AIJA (Association Internationale des Jeunes Avocats).

As Finland is a member of the European Union the Bar Association is also a member of the CCBE (Conseil des Barreaux de la Communauté Européenne). During the last few years contacts have been established with the Baltic countries, especially with the Estonian Bar Association (Eesti Advokatuur).
