Do art advisory services pay for themselves?

What do art advisors charge?

Art advisers charge in four ways: a retainer, an hourly or project fee, a percentage of the purchase price, or a commission paid by the seller’s side. Apart from a 2007 newspaper article, the only published figures we found are one UK-focused adviser’s own, which puts percentage fees at 5% to 20% of the price, an adviser’s remark, in an Artsy article republished in 2021, that 10% is usual up to about $5 million, and an undated page on Judith Benhamou Reports, a site about art and the art market. The luxury assets hub covers the other things collectors buy.

Fee model	Paid on	Figure a source gives	Whose figure it is
Retainer	Time, monthly	£1,500 to £10,000 a month	Modern Contemporary Art, an adviser whose page says it focuses on the UK market or similar high-end art markets, on its own undated fee page, in pounds
Hourly	Hours of advice	£150 to £500 or more	The same firm’s own figure
Project	A defined assignment	£2,000 to £20,000 or more	The same firm’s own figure
Percentage of the price	The purchase or sale price	5% to 20%, and 5% to 10% for high-value transactions, such as those involving blue-chip artists or top-tier auction houses; about 10% for works up to roughly $5 million	The same firm for the first two figures; and Todd Levin, an adviser the page describes as an APAA board member, for the third, in an Artsy article republished in 2021
Commission from the seller’s side	A sale, paid by the gallery	10% described as the standard in 2007; a New York dealer quoted in the same article said many advisers come asking for 15% or even 20%	Marc Spiegler in The Art Newspaper, 30 April 2007, and the dealer he quoted

None of these is a measured average. They are an adviser’s description of its own pricing, one adviser’s remark, and a 19-year-old newspaper article, and the sources do not say what share of advisers charge each way. The Artsy article adds that above about $5 million the percentages “can slide lower”, without giving a figure. The same Artsy article says the Association of Professional Art Advisors (APAA) outlines several common arrangements: a retainer paid monthly or hourly, a salary, a percentage of the value of the works bought, or a combination. A page on judithbenhamou.com, which shows no date or byline, says advisers are paid fees fixed in advance or a percentage of each transaction that “can go up to 10%”. We found no published adviser fee schedule from Paris or Hong Kong. No US licence exists for art advisers. DLA Piper lawyers Diego R. Figueroa Rodríguez and Maria Ojeda wrote in a Florida practice guide, updated in April 2026, that no state or federal agency issues art adviser licences or keeps a register of practitioners.

Which fee model creates the clearest conflict of interest?

A commission paid by the seller’s side creates the clearest conflict of interest, because the adviser earns more when the buyer buys from the paying seller. A percentage of the price creates a different one: the adviser is paid only if the client buys, and paid more if the price is higher. A retainer or hourly fee paid by the buyer alone removes both, which is Unmatched Capital’s analysis of the incentives, not a finding in any source.

Spiegler’s 2007 article called “double-dipping”, an adviser collecting a commission from both the dealer and the collector, the trickiest issue by far with commissions. He wrote that advisers have a financial incentive to deal more with one gallery than another and that the client is too often left in the dark. The article is nineteen years old, so it shows what the objection was and not how common the practice is now.

A percentage fee has genuine merits: the collector owes nothing if nothing is bought, and the Artsy article lists a percentage of the value of works bought among the common arrangements the APAA outlines, and says advisers should accept payment only from the client. A retainer is owed whether or not the collector buys. On the example inputs below, and if the whole $30,000 retainer is charged to a single purchase, a 10% fee costs less than the retainer for any hammer price under $300,000 and more above that.

What do codes and the law say about advisers paid by both sides?

The APAA code bars members from taking compensation that creates a conflict of interest, and DLA Piper’s lawyers say US common law treats an adviser who acts for a buyer as a fiduciary who may not take a seller’s commission without the client’s informed written consent. The code is voluntary: DLA Piper’s guide calls such codes “not legally binding”, though courts may consider them.

The APAA’s code of ethics says members may not keep inventory for sale, accept art on consignment or act as private dealers in any transaction, and do not solicit or accept compensation from service providers or vendors. A member may perform a service that would be, or appear to be, adverse to a client’s interests only if it is fully disclosed and the client consents in advance in writing. Membership is by invitation and requires, among other criteria, five years as a principal of an advisory firm and transparency with clients about the compensation structure. A reader should treat membership as evidence about the adviser’s stated rules and not as a licence or a guarantee.

On the law, DLA Piper’s April 2026 guide says acting for a client in an art deal creates fiduciary duties whether or not a contract exists. An adviser must not accept commissions or benefits from third-party sellers without the client’s informed written consent. Common breaches include receiving compensation from both buyer and seller and failing to disclose a financial relationship with a seller, and a breach can bring restitution and disgorgement of fees, even without a proven loss. The guide is about Florida, and it says the same common-law framework applies across the United States, so a reader in another state should confirm the position with a lawyer there. No source we read describes the rules in London, Paris or Hong Kong, so a collector in those cities should take local advice.

The guide also describes a separate dispute in which the Russian billionaire Dmitry Rybolovlev sued the Swiss art dealer Yves Bouvier, alleging that Bouvier, while acting as his trusted adviser, secretly inflated prices across about thirty-eight transactions. The two reached a confidential settlement in December 2023, and the guide reports no finding against Bouvier. Rybolovlev had also sued Sotheby’s in the Southern District of New York in 2018, claiming that the auction house aided Bouvier on four transactions, and in January 2024 a federal jury returned a unanimous verdict for Sotheby’s.

What does an adviser’s fee do to the cost of owning a work?

An adviser’s fee is paid at purchase and cannot be recovered at sale, so the price must rise further before the buyer breaks even. In the example below, a $500,000 hammer price at Sotheby’s needs a 42.2% rise with no adviser, 48.9% with a $30,000 retainer and 53.3% with a 10% fee.

The example is hypothetical and every input is stated:

• Purchase: a lot bought at a $500,000 hammer price (the price at which the auctioneer’s hammer falls, an example input).
• Buyer’s premium: 28% of the hammer price, Sotheby’s rate for lots up to $2 million effective February 2026, as Grossman LLP reported it in May 2026. That is $140,000, so the buyer pays the house $640,000.
• Exit: a sale at Sotheby’s at its published standard seller’s commission of 10% of the hammer price, which the seller’s contract can change (see the next section). The 2% success fee above the high estimate and the $500 minimum for low-estimate lots are left out.
• Retainer: $5,000 a month for six months, $30,000, an example input with no source, charged in full to this one purchase.
• Percentage fee: 10% of the hammer price, $50,000, an example input set at the level Todd Levin was quoted at in the Artsy article republished in 2021 for works up to about $5 million. Whether the percentage applies to the hammer price or to the $640,000 is a contract term.
• Left out: insurance, storage, shipping, sales tax, resale royalties, tax on any gain, the years the work is held, and whatever the adviser saves or earns the buyer.

$500,000 hammer price	No adviser	$30,000 retainer	10% fee on the purchase	10% fee on purchase and sale
Buyer’s premium at 28%	$140,000	$140,000	$140,000	$140,000
Adviser’s fee at purchase	$0	$30,000	$50,000	$50,000
All-in cost	$640,000	$670,000	$690,000	$690,000
Share of hammer price kept at sale	90%	90%	90%	80%
Hammer price needed to break even	$711,111	$744,444	$766,667	$862,500
Rise needed to break even	42.2%	48.9%	53.3%	72.5%
Result if the hammer price at sale is $750,000	Gain of $35,000	Gain of $5,000	Loss of $15,000	Loss of $90,000

Every figure in the table is Unmatched Capital’s calculation from the inputs above. The $50,000 fee is 10% of the hammer price but 7.8% of the $640,000 paid to the house, and every rise in the table is measured on the hammer price. It pays for itself only if the adviser changes the outcome by that much, for example by a lower winning bid, by catching a fake or a defective title, or by a better exit. The last column shows why the contract decides the cost: a percentage that also applies at sale takes the break-even rise from 53.3% to 72.5%.

The two fee models behave differently as the price changes. Doubling the example to a $1,000,000 hammer price, still in Sotheby’s 28% tier, leaves the 10% fee at 53.3% because it scales with the price, while the $30,000 retainer falls from adding 6.7 percentage points to 3.3, giving 45.6% against 42.2% with no adviser. A flat fee costs the most, relatively, on the cheaper purchase, whereas a percentage fee costs the same relative amount on every purchase.

How do auction premiums and taxes differ in London, Paris and Hong Kong?

At Bonhams, auction premiums for art follow the same banded pattern in London, Paris, Hong Kong and the US, but the bands are in local currency and the tax added on top differs. Sotheby’s help page, updated on 9 September 2026, charges 28% up to £1.5 million in London, €1.75 million in Paris, HK$15 million in Hong Kong and $2 million in New York, then 22% and 15%, so a 500,000 hammer price carries 28% in each. Its rates exclude local taxes, which Bonhams’ pages state, so the schedules below are Bonhams’. From 1 October 2026 Bonhams charges 30% on the first slice of the hammer price and 28%, 25%, 21% and 14% on higher bands, as its pages for London, Paris, Hong Kong and the US set out.

Bonhams, general categories from 1 October 2026	30% band	28% band up to	Tax the page states on the premium
London	First £25,000	£500,000	20% VAT on the premium and charges; a resale royalty of up to £12,500 a lot on lots marked “AR”
Paris (France and Monaco)	First €30,000	€600,000	20% TVA on the premium and charges
Hong Kong	First HK$300,000	HK$6,000,000	None mentioned on the page
United States	First $35,000	$750,000	Sales or use tax added

On a hammer price of 500,000 in each currency, which are not equal in value, the premium is £140,500 in London, €140,600 in Paris, HK$146,000 in Hong Kong and $140,700 in the US, between 28.1% and 29.2% (Unmatched Capital’s calculation). VAT or TVA at 20% on the premium adds £28,100 in London and €28,120 in Paris, which takes the cost of the premium to 33.7%. A buyer’s total in London is then £668,600, so a 10% adviser fee on the total paid would be £66,860 against £50,000 on the hammer price, a gap of £16,860. That is why the base matters.

Sotheby’s says it collects the artist’s resale royalty from buyers where the right applies, and its fee page describes the right as applying to sales in the European Union or the United Kingdom, which include Paris and London; the page says nothing about Hong Kong. The page still gives the threshold as a hammer price above €1,000, but in the UK the right has applied from a sale price of £1,000, with the royalty capped at £12,500 a sale, since 1 April 2024, according to GOV.UK. The French threshold was not read. Sotheby’s gives 10% of the hammer price as its standard seller’s commission, but its fee page says the seller’s contract sets the commission, and The Art Newspaper reported that from 17 February 2025 its seller’s fee reverted to “bespoke terms”. At a negotiated 5%, the worked example’s break-even rise falls to 34.7% with no adviser and 45.3% with a 10% fee (Unmatched Capital’s calculation).

What should be in writing before hiring an art adviser?

A written engagement should state who pays the adviser, on what base and when, and it should disclose every other payment the adviser may receive. DLA Piper’s April 2026 guide lists the key terms of an art advising contract as the scope of engagement, compensation and fee structure, conflict of interest and disclosure, confidentiality, indemnification and limits on liability, non-circumvention, and term and termination.

On compensation, the guide wants the payment schedule and method specified, commissions and third-party benefits disclosed, and dual compensation permitted only with written consent. On conflicts, it says the adviser should disclose significant connections in writing and should not represent buyer and seller without informed written consent. Limits on liability should be narrow and exclude fraud, self-dealing and breaches of fiduciary duty. The contract should also define the term, termination rights and how disputes are resolved. The non-circumvention term protects the adviser, because it stops the client dealing directly with sources the adviser introduced, so a collector should read its scope before signing.

Art Services Network, a directory that curates advisory services, lists six questions for compensation and conflicts. They include whether the adviser is paid only by the client, whether commissions from sellers are disclosed in writing, and whether discounts and rebates are passed to the collector. Two further questions affect the cost, as the worked example above shows: whether the fee is calculated on the hammer price or the total paid, and whether it applies again at sale.

Do anti-money-laundering rules apply to art advisers?

In the United Kingdom the anti-money-laundering rules reach an art adviser who acts as an intermediary in a sale; in the US, no rule we read names art advisers. Regulation 14 of the Money Laundering Regulations 2017 covers a business that trades in, or acts as an intermediary in the sale or purchase of, works of art where the transaction, or a series of linked transactions, is worth £10,000 or more, a threshold in force since 30 June 2026. HMRC’s guidance, last updated on 23 August 2023, still gives the earlier 10,000 euros and speaks only of buying or selling. The regulation does not say whether an adviser who gives advice but never acts as an intermediary in a sale is covered. We did not read the rules for Paris or Hong Kong.

In the United States, the Treasury study of 4 February 2022, required by the Anti-Money Laundering Act of 2020, listed the use of intermediaries, with shell companies and art advisers as examples, among the qualities that may make the high-value art market attractive, and found some evidence of money laundering risk. No Bank Secrecy Act rule covering advisers was found in the sources read.

The Art Market Integrity Act, announced on 23 July 2025, would bring advisers, dealers, galleries and auction houses within the Bank Secrecy Act, DLA Piper reported in August 2025. DLA Piper’s April 2026 guide gave its status as introduced in July 2025, and we did not confirm later action.

What this means before you hire an art adviser

Before signing, a collector can get five answers in writing: who else pays the adviser, what the fee is calculated on, whether it is charged again at sale, which checks on authenticity, provenance and title the fee includes, and what the work must rise by to cover it.

If the collector alone pays, compare a percentage with a flat fee at the amount to be spent; on the inputs above, and for a single purchase, 10% is cheaper than a $30,000 retainer below a $300,000 hammer price. The net return calculator has a box for one-off buying costs, where an adviser’s fee can go beside a 28% buyer’s premium of the kind Grossman LLP reported at Sotheby’s. In London or Paris, also ask whether the percentage applies to the total including VAT. No source we read measures whether buyers with an adviser pay less, avoid more fakes or resell better than buyers without one, so the break-even rise is a hurdle the adviser has to clear, not a verdict on whether advice pays. The collectibles page applies the same two Sotheby’s schedules to a $100,000 lot and reaches the same 42.2%. A collector buying as an investment should also ask what evidence the adviser can show that its advice has lowered what clients paid, since the fee is paid at purchase whatever the result.
