What is a sujeto obligado, and am I one?

A sujeto obligado is a person or firm required by Spanish anti-money-laundering law to apply preventive measures. As an estate agent in Spain you generally are one as soon as you broker purchase or sale transactions.

Art. 2 Ley 10/2010 lists the sujetos obligados. Relevant to the property sector are:

• Estate agents (agentes inmobiliarios): individuals or firms brokering property on a professional basis (Art. 2.1 l) Ley 10/2010).
• Developers (promotores inmobiliarios): on first sales of new-build property.
• Letting agency work: only from 10.000 € monthly rent or 120.000 € annual rent.

You are a sujeto obligado where:

• you act professionally (including as a self-employed autónomo),
• you broker a purchase or a sale,
• you are established in Spain or broker Spanish property.

You are not a sujeto obligado where:

• you broker only private, one-off lettings with no profit motive,
• you act purely in an advisory capacity, without earning from the transaction.

Legal basis: Ley 10/2010, Art. 2

Practical tip: Self-employed agents who sell only occasionally are sujetos obligados too — the duties apply regardless of company size, and even a one-person office must meet the substantive due diligence, reporting and retention obligations. Art. 31.1 RD 304/2014 exempts small obliged entities only from certain formal requirements — the written manual and the external expert report among them — not from due diligence itself. We do not state the thresholds of that exemption here: their reach is not yet settled as a matter of law. On the state of the law: Real Decreto 813/2026, de 7 de octubre (BOE-A-2026-20915) amended the exception catalogue in Art. 31.1 RD 304/2014 and removed Art. 35 — the dedicated internal control body — from it with effect from 28.10.2026. For small offices the outcome is unchanged, because Art. 35.2 itself governs when such a body is not required; the chain of norms, however, is now a different one.
