Who is it for?
The consultancy service is aimed at private collectors, families, heirs, solicitors, notaries, insurers, banks, family offices, museums, cultural institutions, companies with art collections, courts and public bodies.
Every assignment is handled in accordance with the nature of the case: discreetly, independently, thoroughly and with respect for the sensitive nature of art ownership.
Procedure
If you require a valuation, expert appraisal, inventory, academic provenance research or discreet advice, please contact us to arrange an initial exploratory meeting.
Please provide the following information, if possible:
photographs of the artwork or collection
dimensions
signature, inscriptions or markings
any invoices, certificates, publications or provenance details
reason for the expert assessment: insurance, estate, damage, legal case, preparation for sale, donation or advice
Based on this, we can assess which type of expert assessment is appropriate.
