How to Sell Antiquities Legally: Laws, Provenance and Steps

In 1937 and 1939 an Englishwoman named Ethel Inman bought four small antiquities in Cyprus, and she had the government export permits framed with the objects chained directly to them, paper and antiquity hanging on the wall together [1]. The four pieces are now in the Alexander Malios collection in Leipzig. Nobody has to wonder how they left the island.

Most sellers are less lucky: the objects survive and the paper does not. This guide explains what makes an antiquity of any origin legal to sell in the United Kingdom, the United States and the European Union, what buyers and auction houses will ask to see, and how to go about a sale in order. It assumes you already know what you have; if you have only just inherited the pieces, start with what to do with inherited antiquities. Owners of Cypriot material will find a section near the end that routes them to the Cypriot guides.

Is it legal to sell an antiquity?

Usually, yes, if you own it, it was never stolen, and it was not dug up or exported in breach of a law that applies to it. Three sets of rules decide that: the law of the country where the object was found, the law of the country where you sell it, and the law of the country the buyer will take it to. This page is general information about those rules as of 2026, not legal advice; for a specific object of real value, take advice from a cultural-property lawyer.

What does the 1970 UNESCO Convention actually do?

The Convention is a treaty between states, and it does not apply directly to private sellers. Each state party agrees to control excavation and export, to prevent its museums from acquiring illegally exported material, and, under Article 7(b), to ban the import of cultural property stolen from a museum, monument or similar institution in another state party, provided the object is documented in that institution's inventory. At the request of the country of origin it must also take steps to recover and return such an object, with the requesting state paying "just compensation to an innocent purchaser" [2].

The Convention entered into force on 24 April 1972, and it applies only between two countries once both have joined; it is not retroactive [2]. Each country then implements it in its own way, which is why the British, American and European rules below look so different. The year 1970 matters mostly through professional codes. American art museums follow guidelines first issued by the Association of Art Museum Directors in 2008, under which a museum should normally acquire an archaeological object only if it can be shown to have left its country of origin before 1970 or to have been legally exported after that date [3]. Auction houses and the major dealers' associations ask for the same documentation, so a piece without a history before 1970 is harder to sell even where no law forbids the sale.

What are national ownership laws, and why do they matter abroad?

Many countries declare that antiquities in the ground belong to the state. Cyprus has done so since its Antiquities Law of 1935 (Cap. 31), which today forbids export without a licence from the Director of Antiquities and forbids dealing in antiquities on the island altogether [5]. Egypt's Law 117 of 1983 does the same for Egyptian finds [7]. Such laws reach into foreign markets because a court can treat an object taken out in breach of them as stolen property. In United States v. McClain, the federal appeals court for the Fifth Circuit held that pre-Columbian objects removed from Mexico after a law clearly declaring national ownership could be "stolen" under American law [6]. In United States v. Schultz, the appeals court for the Second Circuit upheld in 2003 the conviction of a New York dealer for conspiring to deal in antiquities taken out of Egypt in breach of Law 117 [7].

The date of the law and the date of the export are therefore the first two facts to establish. An object exported under licence, or before the ownership law existed, stands on different ground from one that left without either.

How does UK law apply to selling antiquities?

In the United Kingdom the key statute is the Dealing in Cultural Objects (Offences) Act 2003. It is an offence to "dishonestly" deal in a cultural object "that is tainted, knowing or believing that the object is tainted," punishable by up to seven years' imprisonment [8]. An object is tainted only if it was excavated, or removed from a building or monument of historical, architectural or archaeological interest, in breach of the law of the place where that happened, after the Act came into force on 30 December 2003; "dealing" covers acquiring, disposing of, importing and exporting, and agreeing or arranging to do any of these [8]. The Act is not retrospective and requires proof of dishonesty [4]. Ordinary civil law matters as much: a thief cannot pass good title, so a stolen object can be reclaimed by its owner whoever has bought it since [9]. Taking a piece out of the UK can also need an export licence from Arts Council England, depending on its age, value and category. The UK side of a Cypriot sale is covered in selling Cypriot antiquities in the UK.

How does US law apply?

Two federal regimes apply in the United States. The National Stolen Property Act makes it a crime to transport, receive or sell goods worth $5,000 or more knowing them to be stolen [10], and the McClain and Schultz decisions extended "stolen" to objects taken in breach of a clear foreign ownership law [6][7]. The Convention on Cultural Property Implementation Act of 1983 lets the President restrict the import of designated categories of archaeological and ethnological material at the request of another state party, usually under a bilateral agreement [11]. Restricted material may enter the United States only with an export certificate from the country of origin or evidence that it left that country before the restriction took effect; objects already in the United States before that date are unaffected [11]. Cyprus has had such restrictions under an agreement first signed in 2002. Renewed most recently in 2022, they run to 13 July 2027 as of 2026 and cover Cypriot archaeological material from about the eleventh millennium BC to AD 1770, together with Byzantine and post-Byzantine church material [12]. State prosecutors can also act, and the Manhattan District Attorney's office has seized antiquities from dealers, collectors and museums. The details for Cypriot owners are in selling Cypriot antiquities in the US.

How does EU law apply?

Regulation (EU) 2019/880 governs cultural goods coming into the European Union from outside it. Since 28 December 2020 it has been unlawful to bring in cultural goods that were illegally exported from the country where they were created or discovered, and since 28 June 2025 archaeological objects more than 250 years old need an import licence [13]. The licence is granted on evidence that the object left its country of origin lawfully, or, where it left before 24 April 1972, on evidence of lawful export from the last country where it spent more than five years; certain other categories need only a signed importer statement [13]. A sale from London or New York to a buyer in Paris or Berlin therefore needs a provenance file that a sale within Britain does not. Objects moving between member states fall instead under Directive 2014/60/EU, which lets a member state reclaim an object unlawfully removed from its territory [14].

What will a buyer or auction house ask for?

A provenance file: the documents that take the object back to before 1970, or to a lawful export after it. In practice that means old receipts, export licences, auction catalogues with the lot identified, collection or museum numbers on the object, dated photographs and family letters, with a written account of who owned the piece and when. An established auction house will also check the object against the Art Loss Register and the Interpol database of stolen works of art, ask you to warrant that you own it and can sell it, and record any restoration in a condition report. Source countries watch the market too: Cyprus's Department of Antiquities investigates suspect sales of Cypriot material, and it can confirm whether an export licence number or a lead export tag matches its own files [5]. For Cypriot marks and documents, the guide to export licences, lead seals and labels shows what each one looks like.

How do I sell an antiquity, step by step?

1. Get it identified. Know the culture, class and date before anyone prices it. For Cypriot pieces, send us photos or work through How to Identify Ancient Cypriot Pottery; the guide to replicas, restorations and fakes covers the copies.
2. Assemble the provenance file described above. Leave labels, numbers and seals on the object, and keep groups together.
3. Check where the buyer is. A sale that is simple within one country can need an export licence on one side and an import licence on the other.
4. Get an independent valuation from an appraiser who has no stake in the sale. For Cypriot material, What Is My Cypriot Antiquity Worth? explains what drives price and gives real auction results.
5. Choose a channel that carries out due diligence: an auction house with an antiquities department, or a dealer who belongs to a trade association with a published code. Their checks protect you as well as the buyer.
6. Disclose everything: restorations, gaps in the history, what the family story is based on. Pass the documents on with the object.

Should I sell, donate or return the piece instead?

Many museums now accept antiquities only with the same pre-1970 documentation a sale needs, though a gift can carry tax advantages in both Britain and the United States. For a piece whose recent history is doubtful, voluntary return to the country of origin can be the better course. Both routes are explained, with recent Cypriot cases, in returning or donating Cypriot antiquities, and executors weighing the options for a whole estate should read the guide for executors.

Selling Cypriot antiquities

Cypriot material has its own history, set out in full in Collecting Cypriot Antiquities Today, and a seller should know three facts about it. Lawful private export from Cyprus effectively ended in 1996, so everything legitimately on the market abroad left before then, and in practice mostly before 1974 [5]. Most of it left legally: through excavation shares, licensed dealers such as Petros Kolokasides, the Cyprus Museum's own saleroom, and the numbered export licences described in Licence No. 7070. And the looting that does exist is concentrated after 1974, in the cemeteries of the occupied north such as Lapithos and Bellapais-Vounous, which is why a fine Red Polished vessel with no history before 1974 draws closer questions than a Cypro-Archaic jug with a lead export tag.

The Bichrome amphora shown here, sold through the Department of Antiquities' Sales Register as S.R. 3477/65 and exported under licence in 1969, has the kind of history buyers look for. The step-by-step guide for an inherited Cypriot collection is selling inherited Cypriot artifacts, and the law and practice of each market are in selling Cypriot antiquities in the UK and selling Cypriot antiquities in the US.
