Annual Conference

Köln 2022

Our next XIX Annual Congress will be held from 15 to 18 September 2022 in Köln (Hotel Ernst Excelsior), and will focus on the analysis of the division of the right of ownership (“démembrement”) in a cross-border context and its practical civil and tax implications. We will aim this year to understand how the “démembrement” circulates from a country to another.
