Authentication and appraisal of Corot paintings and prints

Our team consists of experts, researchers, forensic specialists, and lab technicians based in various cities around the world, including Amsterdam, Paris, London, and Washington.

1. You begin by sending us photos of the front, back, signature, and detailed close-ups.
2. Next, provide the dimensions of the artwork.
3. Share any information you have regarding its history, origin, previous owners, and any relevant documents.
4. We’ll give you a quote for our services.
5. Payment is required to proceed.
6. Upon payment, we will carry out the authentication process.
7. Finally, you’ll receive an authentication report, and if the artwork is confirmed authentic, a certificate of authenticity will be included.

We typically conduct the examination after the research phase is complete. However, if you prefer to have it done sooner, we are more than happy to accommodate your request.

Due to the high value of Corot paintings, it is safer for liability and insurance reasons to keep the artwork in your possession rather than shipping it to us.

We examine artwork through:

• High-resolution photographs
• Live video feeds (like Zoom)
• On-site evaluations at any art storage facility around the globe
• In-person assessments at your residence, office, bank, or hotel

We conduct all necessary tests for authentication, which may include materials analysis, dating techniques, special photography, and forensic studies. The specific tests required will vary by case.

The timeframe is typically a few days for prints. For paintings, it can range from a couple of weeks for straightforward cases to several months for more complex ones.

We do not charge for issuing a COA; if the artwork is confirmed authentic, the certificate is provided automatically.

We offer many services—such as answering questions, providing advice, and offering value estimates—at no charge. For additional services, fees begin at $300.

No, we cannot accept payment after authentication, as this would create a conflict of interest. We strive to maintain impartiality in our evaluations.

No, as this would also present a conflict of interest, potentially influencing our conclusions.

Yes, they do. Our authentication process is thorough and detailed, covering all aspects and leaving no room for uncertainty. Our fully referenced reports are based on verifiable facts, ensuring they meet the standards of auctioneers, insurance companies, and financial institutions.

We prioritize the privacy of all our clients, including well-known individuals, art galleries, auction houses, museums, law enforcement agencies, law firms, insurance companies, and banks. We do not disclose their identities or the specifics of our work with them.
