Full scope
Registered for tangible and intangible property, shares in property-holding companies and property damages: one report for the building, the business, the shares and the loss when a case mixes them.
Method and data
French property valuation charter (Charte de l’expertise, 6th edition, 2025), European Valuation Standards 2025, in-house databases, cross-checked methods when the property lends itself to it.

An inheritance, a divorce, a lease, a dispute: each situation has its report
Private client, lawyer, notaire, business, court or institution: each page starts from your situation and tells you which report answers it, under which legal framework and at what price.
Private clients
You do not need to know the vocabulary of valuation. Describe your situation and I will tell you which report you need, in what time and at what price.
See the pageLawyers and notaires
You bring the cases with the highest stakes and you need deadlines that are met, a report built for the proceedings and an expert available for what follows: joint meeting, written observations, hearing.
See the pageBusinesses
Your professional assets are spread between premises, a business, a lease and often an SCI (French property-holding company). I value them together, with the consistency that the bank, the tax authorities and the court expect.
See the pageInstitutions
Your needs are dictated by a framework: mortgage security, five-yearly valuation, net asset value, State valuation office opinion, declaration of public utility. The report respects that framework, under the European Valuation Standards 2025 and the Charte de l'expertise.
