Annual Conference

Bern 2020

Unfortunately, the pandemic forced the Board to postpone to 2021 our 18 th Annual Conference, originally scheduled to take place in Bern, Switzerland from 17 to 20 September 2020. The annual conference was intended to follow on immediately from the Lausanne symposium, jointly organised by swisNot and the Centre of Comparative, European and International Law, to celebrate the 20th anniversary of swisNot!

But the plans for the Conference have merely been put on hold. On 16 September 2021, we plan to hold the Lausanne symposium to celebrate the 20th anniversary of swisNot, and to continue the celebrations at the 18th LEXUNION Annual Conference, which will take place in Bern from 16 to 19 September 2021. The whole event will be organised by our Swiss friends, and will be run under the masterful stewardship of our former director Philippe Frésard.

The Conference will focus on separation of property ownership components (démembrement de propriété) in a cross-border context and its practical civil and tax implications, so that delegates can analyse the issues from an international perspective.
