A certificate of authenticity of art is a document necessary for the attribution of a work of art to an artist. It can include the title of the work, the date of its creation, the name of the artist and various specific elements of the artistic discipline (medium, dimensions, number of copies made, materials, photo of the work, etc.).

The mentions that appear in certificates and documents of authenticity are framed by regulation. The Marcus Decree of March 3, 1981 imposes rules for the authentication of an art object. These rules are primarily aimed at preventing fraud.

Guarantees provided by a Certificate of Authenticity

The certificate is an endorsement that attests to the authenticity of the work, identifying itself with the basic data that is provided in it and by the participation of the artist in its writing and signature.

Whether it is a work of painting, sculpture, photography or graphic work, the Certificate of Authenticity must reflect basic data such as title, author, measurements, date of completion, number of the edition (if it is a serial work), support or materials, being its author the most qualified subject to be able to authenticate it.
