An abstract, expressionist painter from the Netherlands, Willem de Kooning became an American Master of the 20th Century. Known for his Women series and Action paintings, the demand for his work continues to accelerate. Recently de Kooning’s Woman III sold for $137.5 million, becoming the second most expensive painting ever sold. A de Kooning work could be worth millions, but it is important it be certified by recognized experts as authentic.
Formed in 2002, the de Kooning Experts team of art specialists, appraisers, and researchers has been studying, researching, authenticating and appraising his works for clients worldwide.
Depending on your needs, we provide opinions about authenticity, informal estimates of value, full authentications, official appraisals, and certificates of authenticity (COA).

Typically, we conduct the examination after completing the research phase. However, if you prefer an early assessment, we’re more than willing to accommodate that.
Given the significant value of De Kooning paintings, we prioritize safety. For liability and insurance reasons, we recommend that you keep the artwork in your possession rather than shipping it to us.
We examine artwork through:
We conduct all necessary tests for authentication, including material analyses, dating techniques, special photography, and forensic studies. The specific tests required can vary depending on the case.
Typically take a few days. Range from a couple of weeks for straightforward cases to several months for more complex situations.
We do not charge for issuing a COA; if your artwork is authenticated as genuine, the certificate is automatically provided.
We offer many services—such as answering questions, providing advice, and giving estimates of value—at no cost. For additional services, fees start at $300.
We require payment upfront for our services to avoid any potential conflicts of interest that could influence our conclusions, whether regarding authenticity or future sales.
No, we cannot accept payment after the authentication process, as it would create a conflict of interest. Accepting payment at that stage could give us a financial incentive to reach a specific conclusion, which would compromise the integrity of our evaluations.
