How to Confirm Authorship of a Painting?

Confirming the authorship of a painting is one of the most sought-after services in the field of art. Owners of artworks often face situations where the work has the artist's signature, but documents confirming its origin are missing. In such cases, there is a need to conduct an attribution expertise.

Authorship confirmation may be needed when selling a work, processing an inheritance, insuring, participating in exhibitions, or preparing documents for international transportation, especially if the export of paintings from Ukraine is planned. It is important to understand that an assumption about authorship and an official expert opinion are different things. Only professional research allows establishing the degree of probability that the work belongs to a specific author and processing the corresponding documents.

Distinguishing a copy from an original is a very difficult task even for an experienced specialist. For every expert, this is a serious responsibility, since their conclusions involve professional reputation and legal consequences. That is why the results of the research are formalized in the form of a certificate of authenticity of the painting or an attribution opinion.

What Is the Confirmation of Authorship of a Painting

When the Need to Establish the Author Arises

The need to establish the author arises in a variety of situations.

Often, owners acquire paintings without documents and after years try to find out the origin of the work. Similar questions arise after receiving an inheritance, when along with other valuables, works of art are transferred without a confirmed history.

No less often, attribution is required by owners of private collections and those who plan to put a painting up for sale through a gallery, auction, or international platform.

What the Confirmation of Authorship Gives the Owner

Confirmed authorship significantly increases trust in the work and directly affects its value.

The owner gets the opportunity to:

• increase the market value of the work;
• prepare the work for sale;
• arrange insurance;
• use the documents for international transportation.

In many cases, attribution becomes a mandatory stage before processing documents for the export of a work of art.

Why Attribution Is Considered a Complex Expert Task

Attribution expertise requires deep knowledge of art history, the work of specific authors, and the features of artistic materials.

The expert is responsible for their conclusions. An erroneous confirmation of authorship can lead to serious reputational risks and financial losses.

Therefore, the research always includes a comprehensive analysis of several factors, and not just based on the presence of the artist's signature.

How the Attribution Expertise of a Painting Is Conducted

Primary Visual Analysis of the Work

At the first stage, the specialist conducts a visual inspection of the painting.

The following are studied:

• execution style;
• artistic technique;
• composition;
• character of brushstrokes;
• features of the color palette.

Many artists have a recognizable manner of writing that allows for preliminary identification of the range of possible authors.

Investigation of the Author's Signature

The signature is an important, but far from the only, element of the expertise.

The expert determines:

• the originality of the signature;
• the correspondence of the signature to known samples;
• the presence of later inscriptions;
• signs of autograph forgery.

Practice shows that many counterfeit works contain artificially applied signatures of famous artists.

Analysis of Materials and Creation Technology

The next stage is the study of materials.

The following are checked:

• canvas;
• cardboard;
• paper;
• oil;
• acrylic;
• watercolor;
• other artistic materials.

The age of the materials and the features of their use can confirm or refute the alleged authorship.

Comparison with Known Works of the Author

A very important stage is the comparison of the work being studied with already confirmed works of the artist.

For this, the following are used:

• archival materials;
• exhibition catalogs;
• publications;
• museum collections;
• specialized databases.

The more matches found, the higher the probability of authorship confirmation.

How to Distinguish an Original from a Copy

Why Identifying a Copy Can Be Difficult

Modern technologies allow for the creation of very high-quality copies of works of art.

Sometimes a copy can replicate not only the composition but also the materials, execution technique, and even signs of aging.

What Signs May Indicate a Forgery

Experts pay attention to:

• discrepancy of materials with the era;
• errors in the signature;
• unusual execution technique;
• lack of confirmed origin of the work.

However, the presence of one sign is not yet proof of forgery.

Can a Quality Copy Look Like an Original

Yes, it can. That is why visual inspection is often insufficient.

Many copies are so well executed that only a specialist using additional research methods can determine the differences.

When Additional Research Is Required

If doubts arise regarding the authenticity of the work, laboratory studies and technical expertise may be ordered.

What Methods Experts Use to Confirm Authenticity

Art Historical Analysis

This is the main research method, based on the study of the artistic features of the work.

Attribution Research

It includes a comprehensive study of the author, time of creation, and artistic context of the work.

Study of the Origin of the Painting (Provenance)

Provenance helps to trace the history of ownership of the work and confirm its origin.

Laboratory Research Methods

In difficult cases, additional methods are used:

• analysis of paints;
• analysis of canvas;
• investigation of the primer;
• technical expertise.

Such studies allow for the identification of materials that do not correspond to the alleged time of creation of the work.

Attribution Opinion

It contains:

• a description of the work;
• analysis of authorship;
• information about materials;
• the expert's argumentation;
• conclusions of the research.

When the Confirmation of Authorship Is Necessary for the Export of a Work of Art

Permission for the Export of a Painting from Ukraine

In many cases, confirmed authorship helps to obtain permission for the export of a painting from Ukraine, especially if the work has significant artistic value.

Export of Paintings from Ukraine for Sale Abroad

In international sales, documents on origin and authorship significantly increase the trust of buyers.

Painting Export for Exhibitions and Auctions

Professional exhibitions and auction houses often require documents confirming the authorship of the work.

This is especially relevant for cases related to the painting export outside the country.

Icon Export and Items of Cultural Significance

Special attention is paid to objects of cultural heritage.

Therefore, icon export requires additional verification of origin and historical value.

Sculpture Export and Three-Dimensional Works of Art

Similar requirements may apply to processing documents for sculpture export, especially when it comes to the works of famous authors.

In addition, many owners are interested in how to send a painting abroad from Ukraine, and it is the attribution opinion that often becomes an important element of the package of documents for international transportation.

What Materials the Expert Will Need to Conduct the Attribution

Photographs of the Work

For preliminary analysis, high-quality photographs of the painting are required.

Photos of the Signature and Details

Additionally, images of the signature, surface texture, and individual elements of the work are provided.

Information About the Origin of the Painting

Any information about the history of ownership may be useful for the expert.

Documents of Previous Owners If Available

Receipts, contracts, certificates, and other documents help confirm the origin of the work.

How Long the Confirmation of Authorship of a Painting Takes

Standard Terms for Conducting the Expertise

In most cases, the research takes from several days to several weeks.

What the Complexity of the Research Depends On

The terms are affected by:

• the fame of the author;
• the availability of archival data;
• the condition of the work;
• the need for laboratory research.

When Urgent Processing Is Possible

If a preliminary opinion or certificate is required in a short time, urgent expertise is possible.

Common Mistakes of Owners of Works of Art

Attempting to Independently Identify the Author

Information from the Internet cannot replace professional research.

Trusting Unverified Experts

Selling a Painting Without Confirmation of Authenticity

Lack of Documents for the Work

Even if you have an original work, the lack of a history of origin complicates its further use.
