Due Diligence, Provenance and Authenticity

Confidence is built from connected records

Due diligence is sometimes imagined as suspicion entering a pleasurable transaction. In fact, good records protect the pleasure of collecting. They allow the collector to understand what was acquired, from whom, under what description and with which rights or responsibilities. They also make future lending, insurance, conservation, resale and succession considerably easier.

For a primary-market acquisition from a living artist, the essential record usually includes the artist’s name, title, date, medium, dimensions, price, seller, invoice, certificate or other confirmation of authenticity, and provenance from the artist or their authorised representative. Editioned work also needs edition size, number, artist proofs where applicable and information about whether the edition is complete or produced on demand.

Materially complex work should carry further information: fabricators, components, installation instructions, display equipment, software, authorised substitutions, expected change, hazards, care and packing. Environmental claims central to the work should be supported by the relevant source record. Keep these elements together under one collection reference.

Provenance as continuity

Provenance is the history of ownership and custody. In the primary market it may be short, but it is no less important. An invoice from the representing gallery and a certificate linked to the exact work establish a clean beginning. Record any previous exhibition, loan, publication or ownership disclosed at sale. Retain labels and transport documents where they add useful history, but do not detach material from the work without a system for reconnecting it.

Environmental provenance can sit within this broader record. The source of a significant reclaimed object, a named timber, a recovered pigment or an artist-developed formulation may be part of meaning. That history should be recorded with evidence and an appropriate boundary. Provenance does not require every molecule to be traced; it requires significant claims not to become folklore.

Authenticity and artist intention

Authenticity in contemporary art can depend on more than original matter. A technological work may require migration; an installation may be remade from instructions; a performance may exist through authorised re-performance; a modular sculpture may allow several configurations. The artist’s intention, parameters and approval process become central.

Ask what makes this work this work. Is it a unique object, an edition, an instruction, a file, an arrangement or a combination? Who may fabricate replacement parts? Must the artist or estate approve a change? What documentation proves that a future realisation is authentic? The certificate should not be separated casually from the work; for some conceptual or time-based practices, it carries decisive authority.

The same principle applies more quietly to material substitution. If a natural fibre is no longer available, can another species or supplier be used? If a commercial screen fails, can its replacement differ in technology while preserving size, brightness and aspect ratio? If a ceramic component breaks, does repair preserve authenticity better than remaking? These are not abstract questions once ownership has begun.

Condition at acquisition

A condition report records the state of the work at a particular time. It should be proportionate, descriptive and supported by clear photographs. Note existing irregularities, repairs, surface marks, movement or variations that could later be mistaken for damage. For an intentionally changing work, distinguish anticipated behaviour from current condition.

The report protects all parties during transport and installation. Repeat it on arrival, before and after a loan, and after any incident. Use consistent views and light. A photograph without date, scale or orientation can create confusion rather than evidence.

Condition is not a demand for visual perfection. Reclaimed materials may carry holes, stains, abrasions or previous joins; timber may split within an expected range; handmade paper may vary. The key is to know what belongs to the work and what has happened to it.

Customer due diligence and sanctions

The regulated obligations of art market participants belong principally to the businesses involved, but collectors should expect identity and source-of-funds enquiries where required. In the UK, the relevant art market participant threshold changed to £10,000 from 30 June 2026, including linked transactions. Financial sanctions obligations can also apply. A reputable request for identification is not a judgement on the collector; it is part of a lawful and responsible market.

Collectors purchasing through companies, trusts, foundations or agents should be prepared to identify beneficial ownership and explain authority to act. Attempts to divide a purchase into smaller invoices or use an opaque intermediary can create legitimate concern. The gallery should handle personal data securely and explain what is required.

Because rules and risk assessments change, this guide does not prescribe documentation for a particular transaction. Collectors and galleries should follow current official guidance and professional advice.

CITES, restricted materials and international movement

Artworks can contain timber, ivory, shell, coral, feathers, skin, bone or other plant and animal materials controlled under the Convention on International Trade in Endangered Species. Age, reclamation or artistic transformation does not automatically remove restrictions. Species, source, date, destination and purpose may affect whether permits or certificates are needed.

Check before acquisition if international movement is possible, not on the eve of shipment. An unidentified wood or decorative fragment can create delay, seizure or an inability to resell across borders. A collector should not accept vague assurances that a material is old or found. Ask for identification and consult current CITES and national guidance where relevant.

Contemporary artworks may also engage dangerous-goods rules through batteries, solvents, aerosols, powders or magnets. Specialist shippers should assess the actual components and route.

Export, import and taxation

The movement of art across borders can involve export licences, customs declarations, import VAT, duty, temporary admission and cultural property controls. Requirements depend on age, value, classification, origin, destination and whether movement is temporary or permanent. Some older or nationally significant works may require an export licence or be subject to a deferral process.

Collectors should establish which party is importer or exporter of record, who bears taxes and fees, and what documents will return with the work. Sustainable route planning must remain compatible with legal and insurance requirements. A slower sea journey is not useful if paperwork expires before arrival.

Privacy and transparent ownership

Private collectors are entitled to security and discretion, but privacy should not destroy provenance. Collection databases can restrict public access while preserving accurate internal ownership and location. When lending anonymously, the institution can record the owner confidentially. When selling, the provenance can be disclosed appropriately through the intermediary.

Sustainable stewardship depends on information surviving changes of staff, advisor, software and generation. A private fact can remain private without becoming lost.
