AML and KYC Checks When Buying Property in Spain in 2026: The EU AMLR, AMLA's First 40 and What Changes from July 2027

Spain’s property market sits behind a legal framework designed to stop dirty money entering the financial system. If you are buying on the Costa del Sol, the anti-money-laundering (AML) and know-your-customer (KYC) checks are not a formality; they are a legal duty imposed on the notary, the bank, the estate agent and your lawyer by Ley 10/2010. A new EU regulation (2024/1624, the AMLR) will harmonise cash limits and due diligence thresholds across Europe from 10 July 2027, and the EU’s new Anti-Money Laundering Authority (AMLA) has already begun selecting its first 40 directly supervised firms. Here is what each party must do, what documents you will be asked for, and the cash limits that catch foreign buyers out.

What law governs AML checks in Spain?

Spain’s primary anti-money-laundering statute is Ley 10/2010, de 28 de abril, de prevencion del blanqueo de capitales y de la financiacion del terrorismo (BOE-A-2010-6737). It transposes EU directives and sets out who is an “obligated party” (sujeto obligado), what due-diligence measures they must apply, and which authority receives suspicious-activity reports. The implementing regulation is Real Decreto 304/2014, de 5 de mayo, which Spain’s Ministry of Economy opened a public consultation to amend in January 2026, aligning it with the new EU AML package and FATF standards including crypto-asset provisions.

The obligated parties relevant to a property purchase are listed in article 2 of the law. They include entities de credito (banks), notarios y registradores (notaries and registrars), abogados (lawyers, when they participate in transactions), and critically for buyers, promotores inmobiliarios e intermediacion en compraventa o alquiler (real estate developers and intermediaries) when the transaction value reaches EUR 120,000 per year or EUR 10,000 per month. Spain’s financial intelligence unit, SEPBLAC (Servicio Ejecutivo de la Comision de Prevencion del Blanqueo de Capitales e Infracciones Monetarias), receives and investigates the reports these parties file. At EU level, the new Anti-Money Laundering Authority (AMLA), based in Frankfurt and operational since July 2025, began selecting its first approximately 40 directly supervised financial institutions in March 2026, with direct supervision formally starting in January 2028.

Who checks what during a property purchase?

The AML framework distributes the checking duty across every professional gate the buyer passes through. No single party does the whole job; each applies customer due diligence at their own stage of the transaction.

Party	AML duty	What they ask the buyer for
Estate agent	Identify client, verify source of funds, report suspicion	Passport, proof of address, proof of funds
Bank	Identity verification, source-of-funds check, transaction monitoring	Bank statements, origin of transfer, employment proof
Lawyer	Identify client, assess transaction legitimacy	ID, power of attorney, purchase contract
Notary	Identify parties, verify beneficial owner, consult OCP database	Original ID, company documents, declaration of beneficial ownership
SEPBLAC	Receive and analyse suspicious-activity reports	(indirect; acts on reports from the above)

SEPBLAC’s published guidance states that due-diligence obligations have the purpose of “identifying and knowing those persons who intend to establish business relationships with the obligated parties.” That identification includes the titular real (beneficial owner), which must be verified before the relationship begins or the operation executes. The beneficial ownership threshold is 25 per cent of capital or voting rights, confirmed in both Ley 10/2010 article 4.2.b and the new EU Regulation 2024/1624. The AMLR harmonises the calculation method for multi-tier ownership structures: indirect holdings are multiplied through each chain and aggregated, so a person holding 15 per cent through two separate corporate chains totaling 30 per cent is identified as a beneficial owner.

What does the notary specifically do?

The notary is the final gatekeeper in a Spanish property transaction because the escritura publica (public deed) cannot be signed without one. The Consejo General del Notariado runs a dedicated body, the Organo Centralizado de Prevencion del Blanqueo (OCP), created in December 2005. The OCP channels every notary’s AML reporting and has become, by the end of 2025, a pillar of Spain’s financial-crime infrastructure: it has responded to over 415,000 information requests from law enforcement authorities and handled close to 200,000 documentation requests across its 20 years of operation, according to reporting of the June 2026 joint CGN-Policia Nacional conference.

Two databases sit behind the OCP. The Indice Unico Informatizado Notarial (IUN) electronically stores and classifies the content of public deeds authorised by Spain’s more than 2,800 notaries, and is described by the Consejo General del Notariado as Spain’s second-largest database. A Base de Datos del Titular Real (beneficial ownership database), live since May 2014, lets authorities see who actually stands behind a company, even in complex structures. The OCP also maintains a register of politically exposed persons (PEPs) under article 14 of Ley 10/2010, which the FATF has cited as an example of good practice.

In practice, the notary will ask you to present original identification (passport and NIE), and if you are buying through a company, the company’s constitution documents and a declaration of beneficial ownership. If the OCP identifies indicators of laundering, it files a report to SEPBLAC on the notary’s behalf. Your notary’s role in the purchase process is explained in detail in our dedicated guide.

What is the cash payment limit and why does it matter?

A separate but related rule, article 7 of Ley 7/2012, limits cash payments in transactions where at least one party acts as a business or professional (empresario o profesional). The Agencia Tributaria’s published analysis confirms the current thresholds, amended by Ley 11/2021, de 9 de julio:

Payer profile	Cash payment limit	Legal basis
Business or professional (any party)	EUR 1,000	Ley 7/2012 art. 7, amended by Ley 11/2021
Individual with tax domicile outside Spain	EUR 10,000	Ley 7/2012 art. 7, amended by Ley 11/2021
Payments through a credit institution	No limit	Excluded from the rule

Breaching the limit is a grave administrative infringement. The fine is a proportional pecuniary sanction of 25 per cent of the amount paid in cash above the permitted threshold, levied by the Agencia Tributaria across all Spanish territory. For a EUR 500,000 property paid partly in cash above the limit, that fine can reach tens of thousands of euros. The rule applies even if the cash payment was agreed before the law changed; it governs the payment act, not the contract date. If you are buying property in Spain as a foreigner, the EUR 10,000 non-resident limit is the one that applies to you personally, but the moment an estate agent or developer is involved, the EUR 1,000 business limit takes over.

What changes does the EU AML package bring from 2027?

The EU’s Anti-Money Laundering package consists of two instruments that work together. Regulation (EU) 2024/1624 (the AMLR) is a directly applicable EU-wide rulebook that replaces fragmented national rules: it applies automatically in all 27 member states from 10 July 2027 with no national transposition required. Directive (EU) 2024/1640 (AMLD6) sets the mechanisms member states must put in place and requires transposition into national law by the same date, repealing the earlier Directive 2015/849. Together they introduce four changes relevant to property buyers:

EU requirement	Threshold	Legal basis	Spain’s current position
EU-wide cash payment ceiling	EUR 10,000 (business or professional involved)	AMLR Article 80	Spain already caps at EUR 1,000, ten times stricter
Customer due diligence for occasional transactions	EUR 10,000 (lowered from EUR 15,000)	AMLR Article 15	Spain’s AML law already requires identification at all stages
Beneficial ownership threshold	25 per cent of capital or voting rights, harmonised calculation	AMLR Chapter IV	Spain’s Ley 10/2010 art. 4.2.b already sets 25 per cent
Real estate obliged entities expanded	Rental transactions with monthly rent of at least EUR 10,000	AMLR Article 3	Spain’s Ley 10/2010 art. 2.l already covers EUR 10,000/month

The practical impact for buyers in Spain is minimal on cash limits because Spanish law already exceeds the EU standard. The EUR 10,000 ceiling for non-resident individuals aligns with the new EU figure. The AMLR’s main effect is harmonising other member states up to Spain’s level. The lowering of the CDD threshold from EUR 15,000 to EUR 10,000 for occasional transactions means more transactions across the EU will trigger due diligence checks, though Spain’s domestic framework already requires identification at all stages. The AMLR also adds investment migration operators as obliged entities (Article 3.l), a category that includes firms that offered residency-by-investment services, a route Spain closed when it terminated its Golden Visa programme on 3 April 2025 under Ley Organica 1/2025.

Spain’s Ministry of Economy opened a public consultation in January 2026 on amending the implementing regulation (RD 304/2014) to align with this EU package, address crypto-asset risks, and correct practical shortcomings identified during enforcement.

Do I need to declare cash I bring into or move within Spain?

Yes, and this is where many international buyers stumble. The Regulation on the Movement of Payment Media, derived from article 34 of the AML law, sets two declaration thresholds:

Movement type	Declaration threshold	Form
Cross-border (entering or leaving Spain)	EUR 10,000 or more	Modelo S1, to customs
Domestic (movement within Spain)	EUR 100,000 or more	Modelo S1, to Agencia Tributaria in advance

SEPBLAC’s guidance is explicit: if you carry EUR 10,000 or more in cash, cheques or equivalent instruments across the border, you must declare it to customs on Modelo S1 before crossing. If you move EUR 100,000 or more within Spain, you must declare it in advance to the Agencia Tributaria. Undeclared cash can be detained (not confiscated outright), and a fine starting at EUR 600 and rising to double the illegally moved amount can apply. Legitimate funds are returned once proven, but the process is slow and the cash is held in the meantime. This is separate from the bank account closure risks that non-residents face when AML controls flag unusual activity.

How does AML interact with the mortgage process?

If you are financing part of the purchase, the bank’s own KYC runs in parallel with the AML checks above. Spanish banks are obligated parties under article 2.a of Ley 10/2010, and they apply the same due-diligence measures: identity verification, beneficial ownership identification, source of funds, and ongoing transaction monitoring. The bank will ask for proof of income, tax returns from your home country, and a clear paper trail for the deposit. A mortgage approval does not waive the estate agent’s or notary’s AML duties; each party checks independently.

If you are buying without a mortgage, the source-of-funds verification falls more heavily on the estate agent and the notary. Either way, the principle is the same: the money must have a documented, legitimate origin that matches your declared profile. Opening a Spanish bank account as a non-resident early in the process helps, because the bank’s KYC becomes the first checkpoint and the transfer trail starts cleanly.

What documents should a buyer prepare?

To pass AML checks smoothly, assemble these before you begin viewing property:

1. Passport (original, valid) and your Spanish NIE number. The NIE is your tax identification number as a foreigner; our guide to getting your NIE in Málaga covers the process.
2. Proof of address in your home country (utility bill or bank statement, typically under three months old).
3. Source-of-funds evidence: bank statements showing the accumulation of the purchase amount, a sale contract for a prior property, payslips, or a dividend statement. The clearer the trail, the faster the checks.
4. Company documents if buying through a Spanish SL or offshore company: certificate of incorporation, shareholder register and a beneficial-ownership declaration naming the human beings who ultimately own or control 25 per cent or more.
5. Power of attorney if you are signing by proxy: a notarised and apostilled poder.

A good independent lawyer will request these at the start and coordinate with the estate agent and notary so the same documents do not have to be supplied three times. Your property purchase contract will also reference the AML compliance steps.

What happens if a report is filed?

If any obligated party identifies indicators of money laundering, they must file a communication (comunicacion) to SEPBLAC. The report is confidential; the buyer is not informed. SEPBLAC analyses the report and, if it finds grounds, forwards the file to the relevant judicial or police authority or to the Comision de Prevencion del Blanqueo de Capitales e Infracciones Monetarias for sanctioning.

For the buyer, the practical consequence is that a transaction flagged at the notary stage can be delayed or, in serious cases, refused. This is rare in legitimate purchases with clean documentation. The far more common risk for foreign buyers is the cash-limit fine, not a laundering investigation. Keeping every payment traceable through a bank, and declaring any cross-border cash movement, removes both risks. If you are also declaring foreign assets under Modelo 720, the source-of-funds trail you build for AML serves double duty.

The bottom line for 2026 buyers

Spain’s AML framework is not optional paperwork; it is a legal duty on the professionals in your transaction, enforced by SEPBLAC and the Agencia Tributaria. The rules that most often catch foreign buyers are the cash payment limits (EUR 1,000 with a business, EUR 10,000 for a non-resident individual) and the cross-border declaration threshold (EUR 10,000). The EU’s AMLR (Regulation 2024/1624) will standardise a EUR 10,000 ceiling across Europe from July 2027 under Article 80, and its companion AMLD6 (Directive 2024/1640) requires member states to transpose the preventive mechanisms by the same date, but Spain’s stricter domestic cap already applies today. AMLA, the new Frankfurt-based authority, is already selecting the first 40 firms it will directly supervise from 2028. Pay by bank transfer, declare any cash you carry, and have your source-of-funds documents ready before you start. The checks exist to keep the market clean, and a buyer with a clear paper trail passes them without friction.
