Registro de Titularidades Reales — the Spanish UBO register

Spain runs a centralised register of the ultimate beneficial owners of every Spanish-incorporated entity. The Registro de Titularidades Reales (RTR), created by Royal Decree 609/2023, consolidates the older notary-side and Mercantile-Registry beneficial-owner files into a single authoritative source. Obligated subjects performing AML due diligence query it as part of customer onboarding. This piece walks through what the RTR contains, who can query it, how it sits alongside the FTF, and the post-CJEU access reality.

1. What the RTR is

The Registro de Titularidades Reales — RTR — is the central registry of ultimate beneficial owners of legal entities and certain legal arrangements (trusts and similar structures) created or operating in Spain. It is the Spanish implementation of the EU AML directives’ obligation to maintain a centralised UBO register, and consolidates data previously held in separate notary and Mercantile-Registry files.

The legal basis sits in Article 9 of Law 10/2010, fleshed out by Real Decreto 609/2023. The register is operated by the Ministry of Justice with the General Council of Notaries and the Mercantile Registry as data sources.

2. Who feeds the register

The register is fed automatically from existing data sources:

• The Notarial Beneficial-Owner Database — populated whenever a Spanish notary records a transaction requiring beneficial-owner disclosure
• The Mercantile Registry — for legal entities required to file annual UBO information alongside their accounts
• Direct filings by the legal entity itself in defined cases

The obligation to keep UBO information accurate and current sits with the legal entity. Updates are pushed when the underlying ownership changes.

3. What data is captured

Per legal entity, the register holds:

• Identification of the legal entity — name, NIF, registered address, legal form, date of incorporation
• Identification of each ultimate beneficial owner — name, NIF/NIE/passport, nationality, country of residence, date of birth
• The nature and extent of the beneficial interest — percentage ownership, voting rights, control exercised through other means
• For indirect ownership — the chain of intermediate entities
• The date of the most recent update

Where no natural person can be identified as a beneficial owner under the ownership and control tests, the senior managing official is recorded — a fallback explicitly contemplated by Article 4 of the Fourth AML Directive and its successors.

4. The CJEU ruling and the access regime

Current access categories include:

• Obligated subjects under Law 10/2010 — credit institutions, EMIs, PIs, investment firms, notaries, lawyers, accountants and others performing customer due diligence. Access is for AML purposes only.
• Public authorities — judicial authorities, the police, tax authority, SEPBLAC, and other public bodies with statutory functions requiring beneficial-owner information
• Journalists and civil-society organisations with a demonstrated legitimate interest in the specific case
• The general public — restricted; access via specific procedures and only where a legitimate interest is documented

5. How obligated subjects query

An obligated subject performing AML due diligence queries the RTR through a credentialed access route. The query returns:

• The current beneficial-owner record for the legal-entity customer
• The structure of the ownership chain where indirect
• The date of the most recent update — important for assessing freshness

The obligated subject records the query in its AML file, including the date, the result, and the reliance placed on the data. The RTR is a tool, not a substitute for the obligated subject’s own due diligence — Article 7 of Law 10/2010 makes the firm responsible for the accuracy of the beneficial-owner record it relies on.

6. RTR and FTF — different things

The two are complementary. RTR tells you who controls a corporate customer; FTF tells the authorities which PSP holds an individual’s accounts.

7. The EU AML package overlay

The new EU AML Regulation (EU) 2024/1624 and the AMLA Regulation (EU) 2024/1620 reshape the centralised-UBO-register regime across the EU. The Spanish RTR will need to align with the consolidated EU framework, including data structure, interconnection through the Business Registers Interconnection System (BRIS), and the access regime. Material updates to RTR procedures are expected as the EU package phases in.

8. For passporting PSPs

An EMI or PI operating in Spain on Freedom of Services or via a branch is an obligated subject under Law 10/2010 for activity carried on in Spain. The RTR access regime extends to passporting obligated subjects performing customer due diligence on Spanish-incorporated customers. The query process is the same as for domestically licensed firms.

9. FAQ

10. What to do, today

• Confirm your firm’s RTR access route — most obligated subjects access through credentialed integration; some still rely on certified extracts.
• Build the RTR query into the legal-entity onboarding flow as a mandatory step, with the result captured in the AML file.
• Document the firm’s reliance policy — when an RTR record is sufficient, when corroborating evidence is required.
• Watch the EU AML package’s effect on the RTR architecture — material changes to interconnection and access are scheduled.
• Coordinate RTR data with sanctions screening of beneficial owners — the two checks run in parallel on every legal-entity customer.
