In June 2026 the Spanish notarial profession disclosed something most buyers never think about. Of all the suspicious files flagged by the notaries' central prevention body, the Órgano Centralizado de Prevención, roughly 17% are passed to SEPBLAC, Spain's financial intelligence unit, and about a quarter of the operations sent on concern property. The rest are not thrown away. They sit in what one senior figure described as the fridge, waiting to be reactivated if the same name appears again. The system behind that decision cross-references data on 47 million individuals.
None of this is aimed at the Dutch dentist buying a two-bedroom flat near Alicante, or the German couple taking a share in a Mallorcan villa. It explains, though, why that couple will be asked for bank statements, a tax return, the sale contract for the shares they liquidated last spring, and a short written note explaining how they came to have the money. Ten years ago the questions were lighter. By July 2027 they will be identical in every EU member state, because a single regulation will have replaced twenty-seven national interpretations of the same idea.
This article is a plain account of what those checks are, why they exist, what the incoming European rulebook changes, and how the process differs when what you are buying is a share in a company that owns a house rather than the house itself. It is not tax advice, and none of it substitutes for your own lawyer. It is the briefing a well-prepared buyer would want before the first form arrives.
Why property carries the burden
Europol's analysis of the most threatening criminal networks operating in the European Union found that 41% of them use property transactions to launder money. Bricks and mortar hold value, generate a plausible income story, and can be transferred through corporate layers across borders. A flat in a coastal resort is a better washing machine than a suitcase of banknotes, and criminal organisations worked that out long before regulators did.
The response has been to conscript the professionals who stand at the choke points. Notaries, lawyers, estate agents, banks and, increasingly, property managers are what the legislation calls obliged entities. They must identify their client, establish who ultimately benefits from the transaction, understand where the money originated, and report anything that does not add up. They face personal and corporate penalties if they do not. That is the reason a notary in Alicante or a bank in Frankfurt asks you questions that feel intrusive: the alternative, for them, is a fine.
Spanish notaries have been unusually effective at this, largely because of an infrastructure quirk. Every deed signed before a Spanish notary feeds into the Índice Único Informatizado, a single computerised index of notarial acts. That index allows the profession's prevention body to trace patterns no individual notary could see: the same buyer appearing in three provinces, a company changing hands twice in a month, a price that sits oddly against the neighbourhood. Investigators have leaned on it heavily in corruption cases.
One rulebook for twenty-seven countries
Until now, European anti-money-laundering law worked through directives, which each member state transposed in its own way and at its own speed. The result was a patchwork: strict source-of-funds documentation in one country, a lighter touch in the next, and criminals shopping for the softest jurisdiction. The 2024 package ends that arrangement. Regulation (EU) 2024/1624, the AML Regulation, applies directly in every member state from 10 July 2027, with no national translation step. A parallel directive, (EU) 2024/1640, handles the parts that still need national machinery, such as registers and supervisors.
Sitting above the whole structure is a new institution. The Authority for Anti-Money Laundering and Countering the Financing of Terrorism, known as AMLA, was placed in Frankfurt in February 2024 and took up operations on 1 July 2025. It will grow to more than 400 staff. From 2028 it will directly supervise a first tranche of high-risk financial institutions with significant cross-border exposure, roughly forty of them, while indirectly overseeing how national supervisors handle everyone else, including the non-financial sector where estate agency and property management sit.
The regulation also widens the perimeter of who must run these checks. Crypto-asset service providers, crowdfunding platforms, dealers in luxury goods, professional football clubs and agents, and the operators who sell residence and citizenship by investment all become obliged entities. Property is touched twice, since intermediaries in high-value lettings come into scope alongside agents handling sales. Anyone who has wondered why the manager of a holiday home now asks for identification before handing over keys will find the answer here rather than in local officiousness.
For a private buyer, the practical consequence is uniformity rather than severity. The questions asked in Lisbon, Palma and Munich will converge on the same list. A buyer who assembles a clean file once will find it accepted across borders, which is a genuine improvement for anyone who owns in more than one country or intends to.
Cash has already left the room
The most visible change arriving in 2027 is an EU-wide ceiling of €10,000 on cash payments for goods and services in a professional or commercial context. Private gifts between individuals are untouched. The ceiling is a floor for national ambition rather than a cap: member states may keep or introduce stricter limits, and most already have.
Spain's rule, under Ley 10/2010 and subsequent amendments, sets €1,000 where one party acts as a business or professional, rising to €10,000 for individuals who are not tax resident in Spain and are not acting in a business capacity. That non-resident allowance must be documented, and in practice it is irrelevant to a property purchase, since the notary will want the price to arrive by traceable transfer regardless. Italy allows €5,000 generally, with €15,000 for non-resident tourists buying from retailers and travel businesses. France sets €1,000 for its own tax residents and €15,000 for non-resident consumers.
Germany went further and simply closed the door. Under the Second Sanctions Enforcement Act, which entered into force at the end of December 2022, purchases of German real estate from 1 April 2023 can no longer be paid in cash, crypto assets, gold, platinum or gemstones. The notary polices it: the application to transfer ownership at the land registry now goes through the notary, who must assess the evidence of how the price was paid before forwarding it. It is a small, elegant piece of plumbing, and it removed an entire laundering channel in a single stroke.
The direction of travel is consistent. Money that moves through the banking system carries its own history. Money that arrives in a bag does not, and the professionals who would have to vouch for it no longer wish to.
What source of funds actually means
Two phrases get used interchangeably and should not be. Source of funds is the specific origin of the money paying for this purchase: the account it sits in and the event that put it there. Source of wealth is the wider story of how you came to be worth what you are worth: a career, a business sale, an inheritance, three decades of a professional salary. For a mid-six-figure purchase by a salaried European buyer, the first usually suffices. For larger sums, for buyers from higher-risk jurisdictions, or for anyone classed as a politically exposed person, both will be asked for, and the file will be reviewed by someone senior.
In practice the request lands as a short list. Six to twelve months of statements for the account the money will leave. Evidence of the event that created the balance: a completion statement from a property sale, a contract for the sale of a business, a broker's statement showing the liquidation of an investment portfolio, a redundancy or bonus letter, a probate document or a deed of gift. A recent tax return, which does more work than buyers expect, because it corroborates the income story independently. Identity documents and a proof of address. If a relative is contributing, that relative gets checked too, along with a gift letter confirming the money is not a loan.
Borrowed money is not a complication, provided it is declared. A buyer funding part of the price through an equity release on a main residence, a securities-backed line of credit, or a family loan is asked for the facility letter and the drawdown record, and the file is stronger for it, because a lender has already run its own checks. What causes trouble is undeclared borrowing that surfaces later, or a transfer routed through a friend's account to save an international fee. Both look, on a compliance screen, exactly like the behaviour the rules were written to catch.
Three habits make the difference between a two-day review and a six-week one. Pay from an account in your own name, in the jurisdiction you actually live in, and never through a third party doing you a favour. Do not consolidate money from five accounts into one the week before completion, because a fresh balance with no history is the single most common trigger for further questions. Keep the paper. The completion statement from the flat you sold in 2019 is a nuisance to find in 2026 and takes four minutes to file today.
Where a co-ownership share works differently
Almost every property listed by COP is held in a dedicated company, usually a Spanish sociedad limitada, a French SCI, an Italian or German equivalent, or an LLC in the United States. The company holds the deed to one house. Eight buyers hold the shares, typically one-eighth each, and the share is registered property in the legal sense: it can be sold, mortgaged in some structures, and inherited.
That structure changes the choreography of the checks without softening them. The purchase of the house itself happens once, before you appear, and it is the company that faces the notary. What you buy is a share, and the transfer of that share is where your own file is examined: by the operator managing the structure, by the bank receiving your money, and by whichever notary or registrar formalises the transfer under local law. The identity documents, the statements and the explanation of origin are the same. The difference is that you are onboarded to a vehicle rather than bidding at a closing, so the review usually happens calmly, in parallel with the legal drafting, rather than in a scramble two days before a deadline.
There is one point of genuine technical interest. European law defines a beneficial owner by reference to a threshold, and the 2024 regulation set that threshold at 25% or more of shares or voting rights, tightening the old wording of more than 25%. A one-eighth holding is 12.5%. On its own, that sits below the line at which a co-owner is automatically recorded as the beneficial owner of the company in the national register. Where no individual crosses the threshold, the registers fall back to recording those who exercise control by other means, or the senior managing officials of the vehicle, which in these structures means its directors and manager.
Read that carefully, because it is frequently misdescribed. It does not mean a co-owner is anonymous, and it should not be a reason to buy. Your identity is documented by the manager, the bank and the notary, and it is available to competent authorities on request. What it means is narrower: a private individual with a small minority holding in a single-asset property company does not usually appear on a register that other members of the public can search. The obligation to be identifiable to the state is complete; the incidental exposure to everyone else is not.
Who gets to see the register
The visibility question has had a turbulent decade. The fifth directive obliged member states to open beneficial ownership registers to the general public. On 22 November 2022, in joined cases C-37/20 and C-601/20, the Court of Justice of the European Union struck that down, holding that indiscriminate public access was a serious interference with the rights to private life and data protection under Articles 7 and 8 of the Charter, and was neither strictly necessary nor proportionate. Registers across the EU closed to casual searches within days.
The 2024 directive rebuilt access on three tiers. Competent authorities, including the European Public Prosecutor's Office and OLAF, get immediate and unrestricted access. Obliged entities get access for the purpose of customer due diligence. A third tier covers persons with a legitimate interest, with journalists, civil society organisations and academics working on money laundering presumed to qualify. It is a workable compromise between transparency and privacy, and it is the settlement a buyer in 2026 should assume will hold.
The checks that run in reverse
Buyers concentrate on the entry. The exit deserves a paragraph of its own, because the same machinery operates in the other direction and catches people who have stopped thinking about it. When you sell a share, the incoming buyer's funds are examined, and so, in a lighter way, is your own position: the manager must confirm that the person selling is the person who was onboarded, that the proceeds are going to an account in that person's name, and that nothing in the intervening years has changed the picture. If you have moved country, changed name on marriage, or become a politically exposed person by taking public office, that information belongs in the file before the sale rather than during it.
Inheritance is the version of this that arrives without warning. A share passing to a spouse or children triggers a fresh identification exercise on each new holder, because the vehicle acquires members it has never met. Families who have written a will covering the share, and who have told the manager who the likely successors are, hand their executors a straightforward administrative task. Families who have not, hand them a probate process running in one country, a company register in another, and a compliance team that cannot release anything until both are resolved. Sorting the paperwork while everyone is alive and cheerful costs an hour and saves months.
There is also a sanctions dimension that has grown since 2022. Every obliged entity screens names against EU consolidated lists and their national equivalents at onboarding, and then continues screening periodically for as long as the relationship lasts. False matches on common surnames are routine and resolved with a date of birth. The screening is worth understanding for one reason: it explains why a bank that has held your money for fifteen years may still write to ask you to reconfirm details it already has. The obligation is ongoing, not a one-off gate at the entrance.
The timetable, and how to protect it
Compliance is now the most common cause of delay in a cross-border purchase, ahead of surveys, searches and mortgage offers. The reason is rarely suspicion. It is sequencing. A bank asks for a document, the buyer is travelling, the document arrives ten days later in a format the compliance team cannot accept, and a fortnight has gone for want of a scan.
Four steps compress that. First, if you are buying in Spain, apply for your NIE early, since almost nothing formal can be done without it and appointment queues lengthen through the summer. Second, open or refresh the account you will transfer from before you commit to a date, and tell the bank the size and destination of the payment in advance rather than after it is blocked. Third, assemble the file as a single labelled PDF set: identity, address, statements, the origin event, the tax return. Fourth, if a family member is contributing, start their checks at the same time as yours, not once yours are cleared.
Buyers who do this find the process unremarkable. Buyers who improvise find it slow, and conclude that Europe has become hostile to foreign purchasers, when what they have actually met is a filing problem with a deadline attached.
The case for welcoming the paperwork
It is tempting to read all of this as friction imposed on the innocent. The counter-argument is worth stating, because it affects the value of what you buy. Laundered money is indifferent to price. It bids above the market because the object is to place the funds, not to earn a return, and every such purchase distorts the comparable evidence that your own valuation, and eventually your own resale, will rest on. Coastal markets with heavy foreign turnover have carried that distortion for years.
A market where every buyer has explained where the money came from is a market where the price you paid means something. It is also one where the counterparties around you, in a shared structure most of all, have been through the same filter. The vetting that makes onboarding slower is precisely the vetting that makes the other seven owners of a co-owned house people whose funds were documented, whose identity was verified, and whose payment record can be traced. That is not a small thing when a house is jointly held for a decade or more.
The rules will keep tightening. The 2027 regulation extends obliged-entity status further, sweeping in sectors that previously sat outside the perimeter, and AMLA's supervisory reach will grow after 2028. Anyone planning to own property in Europe over the next decade should assume more documentation rather than less, and should build the habit now. The buyers who find this burdensome are, almost always, the ones who kept no records. The buyers who keep records find it takes an afternoon.
