Anyone buying a property in Mallorca must plan not only the purchase price, taxes, and ancillary costs. Banks, notaries, lawyers, and real estate agents are required under Spanish anti-money laundering law to verify who is buying, who is the beneficial owner, and from which legal sources the funds used originate.

Why the origin of funds is checked

Spain protects the integrity of the financial system and other economic sectors with Law 10/2010. Real estate transactions are particularly scrutinized because they can involve high one-time payments, international transfers, corporate structures, and asset reallocations.

The check is therefore not a vote of no confidence in the buyer, but a legal obligation of the parties involved. Obliged parties include, among others, credit institutions, real estate developers and agents, notaries, land registries, tax advisors, and lawyers when they participate in real estate or financial transactions.

In particular, the identity of the buyer, the beneficial owner, the purpose of the transaction, the professional or business activity, and the plausibility of the funds used are checked. In higher-risk cases, additional evidence of the origin of the funds and the origin of total assets may be required.

What buyers should prepare

International buyers should compile the documents early, ideally before the reservation agreement, deposit payment, or account opening. In the luxury segment, a clean set of documents is recommended that not only explains the purchase price but makes the creation of wealth traceable.

valid passport or identity card; if related to Spain, additionally NIE and Spanish tax data, if available
proof of current residential address and tax residence
brief description of professional or business activity
current bank reference or bank confirmation of account holder and availability of funds
bank statements showing the accumulation or receipt of purchase funds plausibly
income statements, tax assessments, dividend statements, salary slips, or audited annual accounts
for sale proceeds: purchase contract, notary settlement, broker statement, or closing statement
for company sale: share purchase agreement, payment proof, tax or closing documents
for inheritance, gift, or trust structure: deeds, estate documents, beneficiary evidence, and payment trail
for investment assets: portfolio statements, sale settlements, inflow of funds to the reference account
for financing: financing commitment, loan agreement, and proof of equity

Documents from abroad should be prepared with an apostille or legalization and certified translation, depending on the country of origin and recipient. Especially for companies, foundations, trusts, or family offices, a clear ownership structure is crucial.

Banks: Account opening, transfer, and payment route

Spanish banks may and must request information on identity, economic activity, and the origin of funds. The Banco de España explicitly states that banks may also request tax returns, income statements, or other documents if necessary for anti-money laundering checks.

For real estate purchases, a traceable payment route is important. Payments should come from an account in the name of the buyer or the purchasing company. For luxury properties, it is often checked more closely whether the purchase price, asset profile, country of origin, corporate structure, and payment route match.

Anyone who does not respond or only partially responds to bank inquiries risks delays, rejection of the transfer, or in certain cases, restriction of an account. Therefore, buyers should not prepare large international transfers only shortly before the notary appointment.

Notary, lawyer, and real estate agent

The notary notarizes the purchase contract but is also part of the Spanish prevention system against money laundering. The Spanish notariat works through the Órgano Centralizado de Prevención with Sepblac and authorities. Notarial data also flows into the Índice Único Informatizado Notarial, which serves, among other things, the prevention of money laundering, terrorist financing, and tax fraud.

The buyer's lawyer normally checks title, encumbrances, building permits, tax issues, and contractual risks. Additionally, insofar as he acts as an obliged professional, he must fulfill his own anti-money laundering obligations. He may therefore request similar documents as the bank or notary.

Real estate agents and project developers are also obliged subjects in purchase transactions. Reputable providers in the premium segment will therefore document buyer identity, beneficial owners, and source of funds before closing or at the latest before accepting larger payments.

International buyers and complex structures

For buyers outside Spain, additional checks are common. This applies not only to buyers from third countries but also to EU buyers if the funds flow through multiple jurisdictions, holding companies, trusts, or private investment vehicles.

For legal entities, it must be disclosed which natural person ultimately controls or is the beneficial owner. Under Spanish law, beneficial ownership generally lies with persons who directly or indirectly hold more than 25 percent of the capital or voting rights or exercise control in another way. If no such person can be identified, management comes into focus.

For buyers through companies, an organizational chart with shareholdings, register extracts, shareholder lists, directors' certificates, powers of attorney, and evidence of beneficial ownership is recommended. For trusts or similar instruments, settlor, trustee, protector, beneficiaries, and controlling persons should be documented.

Special features in the luxury segment

The higher the purchase price, the more important plausibility becomes. For villas, fincas, sea-view properties, and off-market transactions in Mallorca, a simple account balance is often not enough. Banks and advisors want to understand how the wealth was created: through entrepreneurship, dividends, real estate sales, capital investments, inheritance, bonuses, or other traceable sources.

Typical risk factors include very short-term fund movements, payments from third parties, non-transparent corporate chains, offshore structures, frequent cash use, politically exposed persons, high-risk countries, or a purchase price that does not match the known asset profile. In such cases, enhanced due diligence may apply.

The best approach is a brief, orderly note on the source of funds: Who is buying? From what source does the purchase price come? In which account are the funds held? What documents evidence the path of the money? Which persons control the structure? Such an overview saves follow-up questions and reduces the risk that the notary appointment will be postponed.

Cash and means of payment

Real estate purchases in the premium segment should generally be processed through traceable bank channels. In Spain, strict limits apply to cash. For transactions involving a business or professional, cash payments of 1,000 euros or more are generally prohibited; for a natural person without tax residence in Spain who is not acting as a business or professional, the limit is 10,000 euros.

Regardless, movements of means of payment upon entry or exit must be declared from 10,000 euros per person and trip. Within Spain, the declaration threshold is 100,000 euros. Bank transfers are not covered by this declaration of means of payment, but must still be plausible within the framework of anti-money laundering checks.

Practical procedure

Before reservation: Determine buyer structure and check whether buying privately, through a company, or through a family office.
Before the deposit: Document ID, tax data, beneficial owners, and source of payment.
Before account opening or transfer: Submit bank documents and proof of source of funds.
Before the notary appointment: Finalize payment route, checks or transfers, powers of attorney, and company documents.
After closing: Keep purchase documents, payment receipts, and tax documents organized.

Important: Each involved party may request its own documents. The fact that a bank has accepted the funds does not automatically mean that the notary, lawyer, or agent may not ask further questions.

Conclusion

Anti-money laundering checks are a central part of the transaction when buying property in Mallorca. For international buyers and especially in the luxury segment, good preparation often determines whether the purchase can be notarized smoothly. Those who document identity, beneficial ownership, wealth creation, and payment route early build trust and avoid unnecessary delays.
