Before buying, make sure the artwork isn’t stolen, looted, or lost in wartime.

Every day, unsuspecting buyers shell out serious cash for artworks that turn out to be looted, forged or lost in wartime. Even prestigious fairs—boasting rigorous vetting—occasionally miss red flags, and curators warn that no provenance is foolproof. If you’re eyeing an expensive painting, take a moment to verify its legitimacy before you sign that invoice.

Start with the basic checks. Look for labels, stamps or markings on the back of the canvas, or any signs they’ve been removed. Ask the seller for a documented ownership chain and inspect it closely—especially if there's a gap between 1933 and 1945, when Nazi looting was rampant across Europe. A big chunk of old masters or Impressionist works were stolen during WWII, but artifacts from other eras or regions may have similarly dark histories.

Use the free online databases (like the Lost Art Database or the Art Loss Register) to see if a piece is flagged as stolen or suspicious. If you find conflicting information or glaring holes in the provenance, don’t be afraid to walk away. You can also consult independent art lawyers or provenance researchers if the price tag justifies it.

For dealers and auction houses, authenticity is built on trust. The moment a stolen or looted piece slips through, it tarnishes the entire market’s credibility—and you’re the one holding the bill if a legitimate claim emerges down the road. It’s not paranoia; it’s due diligence.

Ultimately, spending a few hours doing real research—rather than just relying on a slick PDF from the seller—can save you years of legal trouble, heartbreak and lost funds. In a market often fueled by impulse and excitement, a little caution goes a long way.
