In the French art market, a few words in a catalogue entry can define the legal scope of an attribution. Expressions such as “by”, “attributed to”, “studio of”, “school of” or “style of” are not interchangeable marketing language. The Marcus Decree gives them specific consequences.

A vocabulary designed to reduce uncertainty

The Decree of 3 March 1981 was adopted to impose greater precision in descriptions used for sales of works of art and collectibles. It requires the seller or intermediary to stand behind the specifications given as to the nature, composition, origin and age of the object.

Alexis Fournol previously analysed the structure and purpose of the text in an article for Interencheres, noting that the Decree creates a hierarchy of attributional certainty and helps objectivise the expectations of the parties.

“By” or the unqualified name of the artist

Under the Decree, the use of “by” or “of” followed by the artist’s name, or the artist’s name immediately followed by the title of the work, guarantees authorship. An indication that a work bears the signature or stamp of an artist also carries a guarantee of authorship unless an express reservation is made.

For auction houses and dealers, an unqualified attribution therefore carries significant legal weight. It should not be used merely because an attribution appears commercially plausible.

“Attributed to”

The expression “attributed to” does not guarantee authorship. It guarantees that the work was produced during the artist’s period of activity and that serious presumptions identify the named artist as the probable author.

The distinction is fundamental. The term introduces uncertainty into the contract, but it is not an empty disclaimer. There must still be serious grounds for the probable attribution.

“Studio of”, “school of” and “style of”

“Studio of” signifies a close link with the artist’s working environment and, under the Decree, with execution in the artist’s studio or under the artist’s direction. “School of” refers more broadly to the work of a pupil or follower influenced by the named master and includes a defined temporal connection.

Expressions such as “style of”, “manner of”, “after” or equivalent formulations do not provide the same guarantee of artist, date or school. Their function is descriptive rather than an authorship warranty.

Why the exact wording matters in litigation

If an authenticity dispute later arises, the court examines what was promised at the time of sale. Under Article 1133 of the Civil Code, a party who accepted uncertainty concerning an essential quality cannot later rely on error concerning that same uncertainty.

The legal question is therefore often not simply “Is the work authentic?” but “What did the seller represent, and is the work consistent with the legal meaning of that representation?”
