Who We Are

Founded in 1979, Berthier & Assocés initially established themselves as renowned specialists in real estate valuation for succession and family law matters.

The firm have since developed, particularly with the arrival of Franck Chanal and Isabelle Sadoux in 2006 and 2007 respectively. Franck is a certified valuer with the Court of Appeal at Grenoble and the Administrative Court of Appeal in Lyon, and Isabelle is RICS qualified, along with being a certified valuer at the Chambéry Court of Appeal.

The expertise brought by Franck and Isabelle has facilitated the development of the firm’s competencies, particularly within the domains of commercial property (including the valuation of commercial rents and eviction compensation), hospitality/tourist assets and in disputes relating to valuation for tax purposes. As we primarily operate in the French Alps and attract an international clientele, we have naturally developed real estate valuation services tailored to overseas-based clients.

Since 1979
