What to do if an artwork is stolen

Verified on 29 October 2026. Should any information have changed, please notify me and I shall update it with the date of the revision.

If the event is occurring or has just occurred, call 112, 091 or 062 and do not confront anyone who may be involved.

An artwork may disappear from a studio, a gallery, a warehouse or during transport. What you do in the first hours, and the documentation that already exists, shape the police report, the insurance claim and the chance of identifying the piece if it circulates again.

This guide covers the theft or disappearance of an artwork and the practical response within Spain. It does not replace legal counsel or the examination of specific insurance policies or contracts. If the piece has been damaged, see What to do if a work is damaged.

What to do in the first hours

  1. Ensure personal safety. Follow the instructions of emergency services and remain clear of any hazardous situations.
  2. Secure the scene. Do not clean, tidy, or perform repairs until authorised by the police. Avoid touching doors, windows, packaging, or other objects that may retain forensic evidence.
  3. Rule out an authorised move. Ask in writing, straight away, those who may have moved the piece: the gallery, the institution, the installer, the courier, the workshop or anyone with access. Do so without making accusations.
  4. Establish a timeline. Record when the artwork was last seen, when its absence was detected, who had access, which areas were open or forced, and which other items are missing.
  5. Preserve records. Retain emails, messages, delivery notes, consignment notes, access logs, and CCTV footage. Do not edit the original files.
  6. Gather the documentation on the work. Have ready the photographs and data that allow the work to be identified when you report it.
  7. Report the loss. If the work is insured, notify the insurer without waiting to assemble a complete file. Further documentation can be sent afterwards.
  8. Do not publicise the disappearance yet. Coordinate with the police unit receiving the report to determine what information is appropriate for public release.

The Guardia Civil recommends securing the scene, reporting the incident promptly, and providing photographs, dimensions, inscriptions, and distinctive features, as a generic description rarely identifies an artwork with certainty.

Legal classification is not required

Describe the facts as known and allow the police to determine the legal classification. For guidance:

  • Theft (Hurto) is the appropriation of movable property belonging to another, with the intent of profit, without the owner's consent, and without the use of force against property or violence or intimidation against persons.
  • Robbery (Robo) involves the additional elements of force against property, or violence or intimidation.
  • Misappropriation (Apropiación indebida) may occur when an individual has received the artwork legitimately, for example, on deposit or consignment, and subsequently misappropriates it or denies having received it.
  • Disappearance or loss is the prudent terminology to employ when it cannot yet be confirmed that a theft has occurred.

If the stolen object has artistic, historical, cultural or scientific value, Article 235.1.1.º of the Criminal Code provides for an aggravated form of theft, punishable by one to three years’ imprisonment. Whether this circumstance applies is a matter for the judicial authority.

Do not accuse a specific individual without sufficient evidence. A false accusation or report, and the simulation of a crime, may give rise to criminal liability in the cases provided for by the Criminal Code.

Documentation to gather

The piece must be distinguishable from similar works. Prepare:

  • Photographs of the whole, obverse, reverse, signature, labels, frame, base, and unique details.
  • Authorship, title, date, technique, medium, and dimensions with and without the frame.
  • Inventory number, edition and numbering, inscriptions, stamps, repairs, and previous condition.
  • Master artwork record, certificate of authenticity, invoice, sale or deposit contract, and catalogue references.
  • Provenance and previous owners or depositaries. The guide How to document the provenance of your own work explains how to organise this information.
  • Invoice, valuation or insured value, with its date. Do not confuse the asking price with a documented value.
  • Policy, special conditions and claim reference number, if one already exists.
  • Chronology, correspondence, access logs, and transport or loan documentation.

Hand over copies and keep the originals. The master artwork record may contain confidential information: provide only what is necessary to identify the piece and prove your relationship to it, and add to it if the police ask. If you have no records, gather whatever exists on your phone, in messages, catalogues or publications. For future works, photographing your work properly facilitates identification.

Where and how to report

Report the facts as soon as possible to the National Police, the Guardia Civil, the competent regional police force, or the judicial authority. For an identifiable or valuable work, reporting in person allows for a clearer explanation of the circumstances and the submission of documentation.

Online reporting has limitations. The National Police Virtual Reporting Office excludes, among other cases, incidents involving violence or intimidation, a known or identifiable perpetrator, witnesses, or offences in flagrante; moreover, a report started there must be signed at a police station to be valid. The Guardia Civil’s electronic reporting system accepts only specific categories and also excludes various cases. If there is forced entry, violence, potential witnesses, an identified person or a large amount of documentation, go in person.

Bring:

  • Identity document.
  • Chronology of events.
  • Photographs and identification sheet.
  • Relationship to the work: author, owner, custodian or representative.
  • Valuation and supporting documentation.
  • Contract, delivery note or consignment note, where a third party is involved.
  • Policy details and information on other affected persons or entities.

Request a copy of the police report and its reference number. Ask how to submit additional files and whether the case will be referred to the specialist heritage unit. The Guardia Civil has a Heritage Group within the Central Operational Unit (UCO) that centralises information on crimes against cultural heritage. An undated official document advises sending photographs after reporting, but some of the contact details and links it contains are no longer current. Confirm the current channel with the unit handling the case.

An official source from 2010 referred to the specialised unit of the National Police as the "Historical Heritage Brigade" and mentioned the Dulcinea database. As its current designation and access have not been verified, request at the police station that the report and the file be forwarded to the competent unit, without relying on outdated contacts.

Whom to inform

Insurer

Article 16 of the Insurance Contract Act establishes, unless the policy grants a longer period, a maximum of seven days from the moment the loss is known to report it. It also mandates providing information regarding its circumstances and consequences. Article 17 requires employing the means available to mitigate its effects.

Report the loss by a means that leaves a record, and check:

  • Who is required to report the loss.
  • Which place and journey were insured.
  • What value is stated in the policy.
  • What documents are required, including the police report if stipulated.
  • What contractual period applies to the search and recovery.
  • What occurs if the work reappears after the indemnity has been paid.

Do not assume that coverage extends to transport, another address or the custody of a third party. How to insure a work of art explains what to check before a move or loan.

Gallery, museum, custodian or institution

Notify the owner and the party holding custody of the disappearance in writing. Request:

  • Their dated account of the events.
  • A copy or reference of their police report.
  • Incoming and outgoing inventory.
  • Deposit, consignment or loan agreement.
  • Applicable policy and notification to the insurer.
  • Access, movement and transport logs.

Coordinate information to avoid contradictory versions. Liability will depend on the facts, the contract and the diligence required; do not treat it as established in your first communication. If the work was on loan for an exhibition, review the loan agreement. If it was consigned or deposited, consult How to work with a gallery.

Carrier

If the work disappeared during domestic land transport, put it on record immediately with the carrier and the insurer. Keep the consignment note, the delivery note, the vehicle details, the changes of custody and all communications.

Article 60 of Act 15/2009 distinguishes between apparent loss or damage, for which written reservations must be made when the goods are received, and non-apparent loss or damage, for which it allows seven calendar days from delivery. A total disappearance during transit should not be treated simply as hidden damage: report it immediately, file a police report and take advice on the regime that applies. The guide How to ship or transport a work covers the documentation to prepare in advance.

How to facilitate identification

After filing the report, ask the police unit what may be disseminated without prejudicing the investigation. A useful alert may include:

  • A clear photograph.
  • Author, title, technique, dimensions and distinctive features.
  • Approximate date and city or country of the disappearance.
  • Reference number that the police authorise for publication.
  • An institutional or verifiable channel for providing information.

Do not publish the exact address, security systems, opening hours, value, personal data of owners or custodians, or the names of suspects. Nor should you disclose information that the police have asked you to keep confidential. The alert should allow the work to be recognised, not the security of the place to be reconstructed or an individual to be singled out without evidence.

Databases and tools

Police databases and INTERPOL

The police report is the verified channel for information to reach the authorities. No public procedure has been located that allows an individual to directly register a work in Spanish police databases or the INTERPOL database.

The INTERPOL Stolen Works of Art Database receives data from national offices and authorised organisations. Any person may request access to consult registered objects, but consultation does not equate to the inclusion of a work.

The free ID-Art application allows for:

  • Consulting the INTERPOL database via data or images.
  • Creating a private inventory in Object-ID format.
  • Exporting that inventory for submission to the police.
  • Notifying a potential match with a work already registered.

The inventory option does not, by itself, register a stolen work in the police database.

Art Loss Register

The Art Loss Register is a private service, not an official registry. Its website allows identifiable objects to be registered on proof of loss and, as of 29 October 2026, states a fee of 17.50 euros per object, plus VAT where applicable. It also warns of possible fees linked to locating or recovering the object, which you should review before engaging the service.

It may complement the police report, but never replace it. Its usefulness depends on operators consulting its database, and it cannot be guaranteed.

What to avoid

  • Delaying the report while awaiting an explanation.
  • Altering the scene or modifying original files.
  • Accusing an individual without evidence.
  • Negotiating alone with someone claiming to possess the work. Inform the police first.
  • Inflating or improvising the valuation.
  • Publishing personal data, security information or confidential details.
  • Relying on a single database or alert.
  • Taking insurance cover for granted.
  • Signing a waiver or liability agreement without understanding the consequences.

If the work is recovered

Inform the police unit or the court handling the case. Notify the insurer, the owner and any registries or entities to which the loss was reported. Do not recover the piece yourself and do not pay anyone offering it without first speaking to the police.

Identify it using photographs, measurements, inscriptions and marks. Document its condition before cleaning, repairing or transporting it again. If it returns damaged, follow the procedure for What to do if a work is damaged.

If compensation has already been paid, Article 53 of the Insurance Contract Act sets out the consequences depending on when the work is recovered and on what the policy provides. Tell the insurer before you dispose of the work.

If it is in the hands of a third party who claims to have acquired it in good faith, do not attempt to resolve the matter through a general rule. Recovery depends on the manner and place of acquisition, good faith, time limits and available evidence. You will require legal advice. To review a piece before buying it, see Before buying a work: provenance, condition and documentation and How to tell whether an artwork is stolen before you buy it.

Matters requiring individual advice

Consult a professional when it is necessary to determine:

  • The liability of a custodian, gallery, institution or carrier.
  • The coverage, exclusions and valuation of a specific policy.
  • Rights against the party who subsequently acquired the work.
  • The status of a work protected as historical heritage.
  • International, air or maritime transport.
  • Recovery in another country.

Itineraries

I am building or managing an art collection

Begin by inventorying and photographing each piece, documenting its provenance and reviewing the insurance. Prior identification is what enables action when a work disappears.

I am going to sell or exhibit

Before handing over the work, establish in writing the custody, value, insurance, transport and procedure for incidents. Maintain entry and exit inventories.

I need to document my work

Combine the master artwork record, identification photographs, certificate and provenance. Keep a copy separate from the location where the piece is kept.

An open conversation

This guide compiles regulations, instructions from authorities and practical recommendations. Reporting channels, contacts and the terms of private services change. If you work in a heritage unit, an insurance company, a gallery, a conservation service or art law and detect an error or a scenario that requires clarification, you may write to me.
