Offering a significant work or collection to a buyer can feel opaque. Owners and their advisors often do not know what a buyer needs to see, who will review it, how long it will take or what could stop a sale late in the process. This guide explains, step by step, how Caldrion Art & Collectibles reviews an opportunity, so that collectors, families, estates, advisors, dealers and specialists know what to expect before the first conversation.
Who this guide is for
We hear from several kinds of counterparties, and the process is the same for each:
- Collectors and families placing a work privately, sometimes for the first time.
- Estates, executors and trustees placing a collection, in whole or in part, on an estate’s timetable.
- Art advisors, private dealers and auction house specialists introducing works on behalf of clients.
- Primary galleries, for our emerging-artist patronage.
We buy as principal, for our own collection, with Caldrion’s own permanent capital. We do not act for others, and we do not offer advisory, valuation or brokerage services.
Step one: check the fit
Before you contact us, it is worth confirming that the work fits our published criteria. They apply to secondary-market acquisitions:
- Value: $250K–$10M+ per work or item.
- Provenance: an unbroken chain of title, fully documented, including literature and exhibition history.
- Condition: museum quality, with a condition report required for every acquisition.
- Market: a liquid secondary market, with an artist or maker with established auction records.
- Authenticity: a certificate of authenticity, mandatory, from a recognized foundation or expert.
- Transaction: private treaty, and also auction guarantees and estate liquidations.
Our emerging-artist patronage acquires directly from primary galleries and degree shows and is not subject to these thresholds.
Our focus areas are post-war and contemporary masters, established mid-career artists, collector automobiles, haute horlogerie, and fine wine and spirits. If a work is significant, well documented and traded in a liquid secondary market but does not fit neatly into one of those areas, tell us about it anyway.
Step two: assemble a complete package
The single most useful thing an owner or advisor can do is send a complete package. We aim to give initial feedback within 72 hours of receiving a complete package. A complete package includes:
- A link to high-resolution images: front, verso, and signatures or hallmarks. For automobiles, include chassis and engine numbers; for watches, dial, case back and movement; for wine and spirits, labels, capsules and fill levels.
- A link to detailed provenance and exhibition history: every known owner, with supporting documents, plus exhibitions and literature references.
- A link to a recent condition report from a qualified conservator or specialist.
- An asking price or valuation rationale: a number, or the reasoning and comparables behind your expectation.
Our forms take links, not uploads. Share a link to non-confidential materials; we sign NDAs promptly when there is mutual interest.
A complete package is the fastest route to a decision. Gaps in documentation are the most common reason a conversation slows down.
Step three: submit through the form
Submit through the inquiry form on this site. Tell us your role (owner, executor, advisor, dealer or specialist), the category, the asking price or valuation if you are comfortable sharing it, where the work is located, and a short description: artist or maker, title or model, date, medium and dimensions, and a summary of its provenance, exhibition history and condition. You may call our New York office, but all initial submissions should come through the form, so that the right people see them in full.
Step four: initial review and feedback
Our team reviews the work, its provenance, its condition and its market. We look first at the four questions we ask of every acquisition: is it significant, is it authentic, is its history clean, and will there be a deep market for it?
If the fit is clear, we will say so and propose next steps. If something is missing, we will tell you exactly what and why. If the work is not for us, we will say that too, promptly and plainly, so that you can pursue other options without delay. We never keep a seller waiting to preserve an option for ourselves.
Step five: inspection and diligence
If there is mutual interest, we sign an NDA and move to diligence. This is where our standards are most visible, and we never shortcut it. Diligence typically includes:
Inspection in person. We, or a specialist we engage, examine the work or object where it is located. For paintings and works on paper, that means surface and support; for automobiles, the car itself and its records; for watches, case, dial and movement; for wine and spirits, the bottles and their storage.
Title and claims. We trace ownership from the artist or maker to the present, search stolen-art and loss registries, and confirm there are no liens, security interests or competing claims. For works whose history passes through periods of wartime displacement, we review ownership with particular care.
Cultural property. We confirm that the work was exported and imported lawfully.
Authenticity. We rely on the recognized foundation, catalogue raisonné committee, maker’s archive or acknowledged expert, and on scientific analysis where it adds certainty.
Condition. We review the condition report and, where useful, commission our own.
How long diligence takes depends on the work. Confirming title, authenticity and condition can take longer for some works than for others—for example, where a foundation’s review is required, or where a provenance gap needs research. We will tell you what we need and why, and we will move as quickly as the evidence allows.
We would rather tell an owner about a documentation gap early than discover it late. Either way, the work is better understood afterward.
Step six: decision, offer and payment
Every acquisition is decided by Caldrion’s investment committee. Decisions are made by a small internal investment committee that meets weekly. We need no outside approvals and no fundraising to close. You deal directly with the people who decide.
When the committee approves, we make a firm offer and agree terms. Because we buy with our own capital, an agreed price is not subject to financing. We pay promptly, as principal, and arrange insured transport and storage. For auction guarantees and estate liquidations, we agree the structure and timetable with the consignor, executor or trustee.
How we think about price
Owners often ask how we arrive at an offer. We form our own view of value, independently of any estimate or asking price, from several sources of evidence: auction results for comparable works or objects, what we learn about private demand, the significance and documentation of the specific work, and its condition. We think in terms of a range of outcomes and what drives them, not a single number.
If your asking price is within the range the evidence supports, we will say so and move quickly. If it is not, we will explain our reasoning, which owners often find useful even when we do not reach agreement. We do not make low opening offers in the hope of negotiating upward, and we do not renegotiate an agreed price unless diligence reveals something material that was not disclosed.
A note for advisors and dealers
We maintain active relationships with art advisors, private dealers, auction house specialists, and the lawyers, trustees and executors who look after estates. We review off-market opportunities on a rolling basis, whatever the auction calendar.
We protect advisors and gallerists on the works they introduce, and we never go around the person who brought us a work. If you introduce a work, we deal through you. Tell us at the outset how you are compensated and what your client needs, and we will respect that throughout.
A note for estates
Executors and trustees face particular pressures: a timetable, a duty to the estate and, often, a family that would prefer discretion. We can act on an estate’s timetable and acquire a collection in whole or in part. We are comfortable working alongside the estate’s lawyers and appraisers, and we understand that the process must be documented carefully.
What makes a conversation go well
In our experience, a few habits make the process faster and more pleasant for everyone:
- Be candid about condition and history. Every work has a story. We would rather hear it from you.
- Share what you have, even if it is incomplete. We can often help identify where missing documents might be found.
- Tell us what matters to you. Price, timing, privacy, where the work goes: knowing your priorities lets us structure an offer that serves them.
- Keep it private. A private treaty sale is not announced, and if a deal is not reached, nobody needs to know the work was offered.
What we will not do
To save everyone time, we do not acquire works without a documented chain of title or a certificate of authenticity, works subject to restitution claims, liens or unresolved questions of ownership, cultural property that cannot be shown to have moved lawfully, or works whose condition falls short of museum quality. We do not buy fractional interests, shares in pooled art vehicles or tokenized claims on a work. And we do not go around the person who introduced a work.
If your work fits, we would be glad to hear from you.
