Estate agent regulation in Spain: the API college, three regional registries and AML duties (2026)

A foreign buyer’s first contact on the Costa del Sol is usually an estate agent, not a lawyer. So it matters how that agent is regulated, what qualifications they must hold, and what protections exist if something goes wrong. Spain’s answer surprises most buyers: there is no national licence, no mandatory qualification, and no universal insurance requirement. The framework is a patchwork of a voluntary professional college, three mandatory regional registries (Catalonia, Valencia and, under a 2026 Andalusian law, the Costa del Sol’s home region), and a federal anti-money-laundering regime that applies regardless of title.

Is estate agency a regulated profession in Spain?

No, not at national level. Estate agency in Spain is a liberalised activity, meaning anyone can legally offer real estate intermediation without holding a specific licence or belonging to a professional body. The decisive statute is Real Decreto-ley 4/2000, de 23 de junio, de Medidas Urgentes de Liberalización en el Sector Inmobiliario y Transportes, which abolished the previous monopoly of API-qualified agents and opened the market to uncredentialed intermediaries. The reform was later consolidated in Ley 10/2003.

Before 2000, practising as a real estate agent required membership in a Colegio Oficial de Agentes de la Propiedad Inmobiliaria. After liberalisation, college membership became voluntary. The API colleges continue to exist as public law corporations under Real Decreto 1294/2007, which approved the current Estatutos Generales governing the 46 official colleges and their Consejo General (CGCOAPI). But membership is a professional credential, not a legal precondition for trading.

This places Spain in a different category from the UK, where estate agents must register for anti-money-laundering supervision, or France, where the loi Hoguet requires a professional card. A buyer in Spain cannot assume an agent is qualified, insured or accountable simply because they operate from a high-street office.

What is the API certification and who grants it?

The API (Agente de la Propiedad Inmobiliaria) is the only nationally recognised real estate qualification in Spain. It is governed by Real Decreto 1294/2007, which sets out the statutes of the official colleges. To join a college as a practising API, an applicant must satisfy three conditions under Article 1 of the statutes:

Requirement	Detail
Age and capacity	Legal age, no incapacity disqualifying practice
Qualification	Official API title issued by the Ministry responsible for housing, OR a university degree (graduate, licenciado, diplomado, engineer or architect)
Conduct	No criminal record disqualifying professional practice

On entry, the new member must also constitute a bond (fianza) in conditions set by the college and pay the membership fee. The bond secures the relationship between the college and its member; it is not a client-protection fund in the sense of a compensation scheme.

According to the Consejo General de los COAPI, there are 46 official colleges across Spain. The API census lists 23,000 registered agents, of whom 5,300 are actively colegiados (practising members). The General Council, headquartered in Madrid, represents the profession before the state administration and autonomous communities.

The practical value of an API agent is threefold: verifiable training, a code of conduct enforced by the college’s disciplinary machinery, and the bond. If an API agent breaches their obligations, a client can file a complaint with the college, which can suspend or expel the member under the disciplinary provisions of the statutes. This recourse does not exist against an uncollegiated agent.

Which Spanish regions require estate agent registration?

Three autonomous communities have stepped into the regulatory gap left by national liberalisation: Catalonia, the Comunitat Valenciana and, most recently, Andalusia. Each operates a mandatory registry that an agent must join before practising residential intermediation in their territory.

Comunitat Valenciana (RAICV). Decreto 98/2022, de 29 de julio, del Consell, created the Registro de Agentes de Intermediación Inmobiliaria de la Comunitat Valenciana. Registration is mandatory for anyone intermediating in real estate transactions in Valencia, Alicante or Castellón. The decreto requires:

Requirement	Physical establishment	Telematic-only agent
Surety insurance or bank guarantee (per year)	EUR 60,000	EUR 300,000
Professional civil liability insurance (per claim/year)	EUR 600,000 (sublimit EUR 150,000 per victim)	EUR 1,000,000 (sublimit EUR 150,000 per victim)
Professional capacity	API title, OR university degree in social/juridical sciences or engineering/architecture, OR 200+ hours of certified real estate training	Same

The surety protects clients if the agent cannot transfer funds they have received. The civil liability policy covers professional negligence across EU territory. Registration is indefinite but subject to suspension or cancellation if conditions are not maintained.

Catalonia (AICAT). Catalonia operates its own Registro de Agentes Inmobiliarios, administered by the Agència de l’Habitatge de Catalunya under Decret 12/2010 and Llei 18/2007. Registration is mandatory and grants the status of agente inmobiliario homologado. Agents must present professional civil liability and surety (caución) insurance policies to obtain their registration number, which must appear in their advertising and contracts.

Andalusia (new, 2026). Ley 5/2025, de 16 de diciembre, de Vivienda de Andalucía, published in BOJA 247 on 24 December 2025, creates the Registro de Agentes Inmobiliarios Especializados del Sector Residencial de Andalucía (Articles 49 to 53). The law entered into force on 24 January 2026, one month after publication. The registry is public, administrative, free and mandatory. Article 50.3 declares registration a prerequisite for exercising residential intermediation in Andalusia, which covers the entire Costa del Sol from Nerja to Tarifa. However, the law ties full enforceability to the registry being operational: the Junta’s housing department must stand it up within two years of entry into force, placing the deadline at January 2028 (Disposición Final Séptima). Until the registry opens and its implementing regulation sets the minimum insurance amounts, the obligation is declared but not yet enforceable.

Inscription works through a declaración responsable filed before starting activity (Article 51), accrediting four categories of requirement under Article 52:

Requirement	Detail
Professional capacity (any one route)	API title issued by the Ministry, OR a university degree in social/juridical sciences or engineering/architecture, OR at least four years of verified real estate sector experience (via vida laboral or self-employment registration), OR current API college membership
Specialisation training	At least 100 hours of official training in residential intermediation and protected housing, obtained within the four years before filing, covering the business owner and 50 per cent of employees
Solvency (Article 53)	A financial guarantee covering funds received during intermediation, OR a professional civil liability insurance policy covering damages from the activity. Minimum amounts are set reglamentarily by business volume. Policy or guarantee details must appear in the client’s mandate contract
Criminal record	No convictions related to real estate intermediation in professional practice

Agents should prepare to comply by securing the required training, insurance and documentation ahead of the registry opening. The law’s sanctioning regime (Título VIII) will apply once enforcement begins.

This is a material change for Costa del Sol buyers. An agent in Marbella or Estepona will need a regional registration number once the registry is operational, not just the voluntary API credential. Until the registry opens, the API college remains the only structured credential available in Andalusia, and it remains voluntary.

What anti-money-laundering duties apply to estate agents?

Regardless of college membership or regional registration, every Spanish estate agent and developer with sufficient turnover is a sujet obligé under Spain’s anti-money-laundering framework. The primary statute is Ley 10/2010, de 28 de abril, de prevención del blanqueo de capitales y de la financiación del terrorismo, developed by Real Decreto 304/2014. The supervisor is the Servicio Ejecutivo de la Comisión de Prevención del Blanqueo de Capitales e Infracciones Monetarias (SEPBLAC).

Article 2.1(l) of Ley 10/2010 lists “promotores inmobiliarios y agentes inmobiliarios” among the sujetos obligados, with a turnover threshold: the obligation applies to agents and developers with annual real estate revenue of at least EUR 120,000, or EUR 10,000 per month. An agent below that threshold is not a sujet obligé for AML purposes, though most active agents on the Costa del Sol exceed it.

The obligations, set out on SEPBLAC’s official obligations page and detailed in the law, fall into three groups:

1. Due diligence. Identify and verify the identity of clients and beneficial owners; assess the risk of each business relationship; apply enhanced measures for higher-risk clients (including non-resident buyers and complex ownership structures).
2. Information. Keep records of transactions and due diligence measures for at least 10 years; report operations suspected of being linked to money laundering or terrorist financing to SEPBLAC, including systematic reporting of certain predefined operations.
3. Internal control. Appoint a compliance officer; adopt and maintain a written AML prevention manual; train staff; establish audit procedures.

A separate obligation applies to cash. Article 34 of Ley 10/2010 requires individuals entering or leaving Spanish territory with EUR 10,000 or more in cash (or equivalent) to declare it. Failure to declare carries a fine from EUR 600 up to twice the value of the funds. While this duty falls on the individual, not the agent, an agent facilitating a cash-heavy purchase should flag the requirement and document the transaction trail.

For a foreign buyer, the AML regime has a practical upside: a compliant agent will ask for identity documents, proof of funds and source-of-wealth evidence early in the transaction. An agent who never asks is either below the turnover threshold or non-compliant. Neither is reassuring on a high-value purchase.

How does an API agent differ from an unregulated intermediary?

The difference is not legality but accountability. Both can legally market and intermediate property. The table below sets out the practical distinctions a buyer should weigh.

Factor	API-collegiated agent	Uncollegiated agent
Qualification	Verified (API title or university degree)	Not verified
Code of conduct	Enforced by college; complaints mechanism	None beyond consumer law
Bond (fianza)	Posted with college	None
Disciplinary recourse	Suspension or expulsion	None
Regional registry (Valencia/Catalonia/Andalusia)	Typically registered	Must also register to practise in those regions
AML compliance	Required if above threshold	Required if above threshold

The key point is that AML obligations are universal above the turnover threshold, so an uncollegiated agent in Andalusia is not exempt from due diligence duties. But the client has no professional body to turn to if the uncollegiated agent acts negligently. The only recourse is civil litigation, which is slow and costly.

For a buyer’s independent lawyer, the agent’s status is one of several due-diligence inputs, not a guarantee. A lawyer will check the property’s title, debts and planning status regardless of who sells it.

How can a foreign buyer verify a Spanish estate agent?

A practical verification checklist, using only primary sources:

1. API college number. Ask the agent for their colegiación number and the name of their Colegio Oficial. Verify through the Consejo General de los COAPI website, which lists the 46 member colleges. Each college maintains a public register of practising members.
2. Regional registry (if applicable). For property in the Comunitat Valenciana, ask for the RAICV inscription number issued under Decreto 98/2022. For Catalonia, ask for the AICAT number. For Andalusia, once the registry is operational, ask for the Andalusian registry inscription number under Ley 5/2025. All three registries are public.
3. Insurance. Request proof of professional civil liability insurance and, in Valencia or Catalonia, the surety or bank guarantee. The RAICV minimums (EUR 600,000 liability, EUR 60,000 surety for a physical establishment) are a useful benchmark even where you are buying in Andalusia, where the implementing regulation has not yet set the amounts.
4. AML compliance. A compliant agent will request your identity documents and source-of-funds evidence as part of their Ley 10/2010 obligations. If they do not, ask whether they are registered with SEPBLAC as a sujet obligé.
5. Written mandate. Ask whether the agent holds a written service agreement with the seller (mandato). A serious agent will have documented their instruction; a referral from a buyer’s guide process should also confirm who pays the commission and when.

A buyer who follows these steps is doing more diligence than most. The common mistakes buyers make in Spain often start with trusting an unverified agent’s representation of a property’s status.

What should a buyer do if an agent acts improperly?

If the agent is an API member, file a written complaint with their Colegio Oficial. The statutes of Real Decreto 1294/2007 provide for disciplinary proceedings that can result in suspension or expulsion, and the college’s disciplinary machinery is faster than civil courts.

If the agent is registered in the Comunitat Valenciana, Catalonia or Andalusia, report the breach to the relevant housing authority, which can suspend or cancel the registration under Decreto 98/2022 (Articles 9 and 10 for Valencia), the Catalan registry rules (Decret 12/2010), or Andalusia’s Ley 5/2025 sanctioning regime (Título VIII).

If the agent is neither collegiated nor regionally registered, the recourse is civil. A lawyer can bring a claim for professional negligence or breach of contract. In cases of suspected money laundering, a report can be filed with SEPBLAC, which can investigate and sanction under Ley 10/2010.

In all cases, the independent lawyer engaged for the purchase should be the first point of contact. They can assess whether the agent’s conduct creates liability for the seller, the buyer, or both, and whether it affects the off-market or open-market transaction in a way that should pause the purchase.
