Leaders in Research, Advocacy and Restitution

Established in 1993

Every member of our international team of historians, art provenance researchers and legal experts helps to obtain justice for families whose property was misappropriated during the Second World War. Over the years, we have recovered important art, cultural artifacts and other looted assets but the primary goal of our work is even more significant: helping to right personal and historic wrongs through restitution.

What We Do

Mondex serves its clients by advocating on their behalf, combining art and science in its methods and research, and working closely with its international legal team, which provides multi-jurisdictional expertise in developing legal and restitution strategies.

Research

The material goal driving all of our research is the return of property that was lost to persecution. In theory, this goal is straightforward. But in practice?

Advocacy

At Mondex, we advocate successfully for our clients when we achieve a restitution agreement. In some cases, restitution occurs once we communicate with the possessor of a misappropriated artifact, a possessor who may be unaware that the artifact was stolen.

Restitution

At its most basic, restitution refers to ‘the restoration of something lost or stolen to its proper owner.’ Our restitution services at Mondex take things further, which is part of our value to clients.
