Terms of Service
Last updated: 4 November 2026
These terms govern the use of katrenko.art, operated by Alina Katrenko, an independent art advisory practice in New York and Miami (“we”, “us”). By using the site you accept them.
Information only
Content on this site is general information about art, the art market and our services. It is not legal, tax, investment or insurance advice, and it is not an offer to buy or sell any work of art.
When an engagement begins
Sending a request or receiving a free first review does not create a client relationship. Paid work begins only under a written agreement that sets out the scope, the fee and the deadline. The free first review is a preliminary opinion based on the photos and information you provide.
Market value opinions and formal appraisals
- A market value opinion is a researched written opinion for your private decisions. It is not an appraisal for tax, estate, donation, court or insurance-claim purposes.
- Where such an appraisal is required, it is prepared and signed by a credentialed partner appraiser (AAA, ISA or ASA) in line with USPAP.
- We do not issue certificates of authenticity. Where attribution matters, we refer you to the recognized authority for the artist.
Fees and independence
Fees are agreed in writing before work starts and never depend on the value we find. We do not value a work that we are paid to sell, and we disclose any commission in writing before a transaction.
No guarantee of results
Values, auction estimates and market comments reflect information available at the time. The art market changes, and we cannot guarantee any price, sale or outcome.
Your materials
When you send photos or documents, you confirm that you may share them. We use them only to answer your request and carry out agreed work, and we keep them confidential.
Intellectual property
Texts, design and the ALINA mark on this site belong to Alina Katrenko unless stated otherwise. Images of artworks belong to their rights holders. Copying requires our written permission.
Limitation of liability
To the extent permitted by law, we are not liable for decisions made on the basis of general information on this site. Liability under a paid engagement is limited to the fee paid for that engagement, unless the agreement says otherwise.
Governing law
These terms are governed by the laws of the State of New York. Disputes are resolved by the courts of New York County, New York.
