1. Spain's UBO Register: The State of Play in 2026
Spain has one of the most structurally complex beneficial ownership frameworks in Europe — not because the register doesn't exist, but because UBO disclosure obligations run through multiple channels simultaneously: the Mercantile Registry, the Central UBO Register, and since February 2025, the Spanish Tax Agency. Understanding which obligation applies, to whom, and through which channel, is the first compliance challenge.
The centrepiece is the Registro Central de Titularidades Reales (RCTIR) — the Central Register of Beneficial Ownership — created by Royal Decree 609/2023 of 11 July 2023 and operational since 19 September 2023. Managed by the Ministry of Justice through the General Directorate of Legal Certainty and Public Faith, the RCTIR functions as a central aggregation point, drawing beneficial ownership data from existing sector-specific registries — Mercantile, Foundations, Cooperatives, Associations — and making it queryable via a legitimate interest model.
The register is technically public — Spain did not close public access following the CJEU's November 2022 ruling in the way France, the Netherlands, or Italy did. Instead, Spain implemented a legitimate interest (interés legítimo) access model from the outset. In practice, however, the register is virtually inaccessible to foreign entities: access requires a Spanish digital identity (DNI, NIE, or empresa digital certificate), all correspondence must be conducted in Spanish, and Transparency International's Spanish subsidiary took six months to be granted access — receiving only partial UBO data even then.
The result: Spain's RCTIR exists, is technically accessible, but creates a structural barrier for non-Spanish compliance teams that is as effective as a formal closure in practice.

2. What Is a UBO Under Spanish Law?
The UBO definition in Spain flows from Article 4 of Law 10/2010 (the AML Law) and Royal Decree 304/2014. The Spanish term is titular real — literally "real holder." The definition follows the standard EU cascading logic.
Step 1: Ownership or control (the 25% threshold)
A titular real is any natural person who directly or indirectly holds more than 25% of the share capital or voting rights of a legal entity, or who exercises control through other means. Indirect ownership is traced through the full chain — intermediate legal entities are looked through until a natural person is identified.
Step 2: Control by other means
Where the 25% threshold is not met through ownership, control through binding agreements, rights to appoint or remove majority board members, veto rights over strategic decisions, or other contractual arrangements qualifies a natural person as the titular real.
Step 3: Assimilated UBOs (titular real asimilado)
If no natural person can be identified through ownership or control, the members of the governing body (administradores) are deemed the assimilated UBOs. Where the governing body is a legal entity, its natural person representative is designated. This fallback is required — Spanish entities cannot file with a blank UBO field.
ℹ️ Dual Reporting Obligation Since February 2025
Since 3 February 2025, Spanish companies must declare their UBO in two places: (1) the Mercantile Registry annually with annual accounts, and (2) the Spanish Tax Agency (Agencia Tributaria) via Form 036 every time a corporate change is notified — modification of the governing body, address change, or other significant transactions. This parallel obligation, introduced by Royal Decree 117/2024, significantly increases the compliance surface for companies with frequent structural changes.
Entities that must register
| Entity Type | In Scope? | Filing Channel | Notes |
|---|---|---|---|
| Sociedad Limitada (S.L.) | ✓ Yes | Mercantile Registry + RCTIR | Most common Spanish entity form; annual UBO filing with accounts |
| Sociedad Anónima (S.A.) | ✓ Yes | Mercantile Registry + RCTIR | Annual UBO filing with accounts; shareholders not publicly disclosed |
| Cooperatives | ✓ Yes | Cooperative Registry + RCTIR | — |
| Foundations (Fundaciones) | ✓ Yes | Foundations Registry + RCTIR | UBO = persons with 25%+ voting rights over governing body (patronato) |
| Associations (Asociaciones) | ✓ Yes | Associations Registry + RCTIR | UBO = persons with 25%+ control over representative body |
| Trusts (foreign) with Spanish nexus | ✓ Yes | Direct to RCTIR | Spain does not recognise trusts under its own law; foreign trusts with Spanish nexus must register directly with RCTIR |
| Entities without legal personality with Spanish nexus | ✓ Yes | Direct to RCTIR | Must file before beginning business activities in Spain |
| Listed companies on EU regulated markets | ✗ Exempt | — | Subject to capital markets disclosure rules; exempt from UBO register filing |
| Sole traders (autónomos) | ✗ Exempt | — | Natural persons — no separate UBO filing required |
Foreign Trusts with a Spanish Nexus: a Unique Obligation
Spain does not recognise trusts as a legal instrument under its own law — no Spanish domestic trust exists. But foreign trusts (governed by UK, Jersey, Cayman, or other foreign law) that establish business relationships, carry out occasional transactions, or acquire real estate in Spain must register their UBOs directly with the RCTIR before beginning those activities. The filing obligation falls on the trustee (or the settlor in the trustee's absence, or the beneficiaries as a last resort). For private wealth structures and family offices with Spanish real estate or investment activity, this is a frequently missed obligation with no grace period.
Quick reference: what data is available by entity type?
| Entity Type | Shareholder Data Public? | UBO Register? | Best Data Source | Practical Route |
|---|---|---|---|---|
| S.L. (Sociedad Limitada) | ✗ No — libro de socios private | ● RCTIR — LI required, Spanish ID needed | RCTIR (if accredited) or ownership graph | No public shareholder data. Require Spanish institutional standing for RCTIR, or trace via group structure. |
| S.A. (Sociedad Anónima) | ✗ No — libro de accionistas private | ● RCTIR — LI required, Spanish ID needed | RCTIR (if accredited) or ownership graph | As S.L. No public shareholder data. UBO register requires Spanish identity. |
| Foundation / Association | ✗ No | ● RCTIR — LI required | RCTIR or voluntary disclosure | Governing body members publicly listed in sector registries. UBO requires RCTIR access. |
| Trust (foreign, Spanish nexus) | n/a | ● RCTIR — direct registration | Voluntary disclosure / trustee | Trustee must file directly with RCTIR before beginning Spanish activities. |
| Listed company (EU regulated market) | ✓ Yes — market disclosure | ✗ Exempt | CNMV (Spanish securities regulator) | Major shareholders disclosed via CNMV. No RCTIR filing required. |
3. What UBO Data Is Available in the RCTIR
The data held by the RCTIR is more comprehensive than what is accessible to most parties. Access is tiered: authorities get everything, obliged entities get full data, and those with legitimate interest get a significantly restricted subset.
| Data Field | Filed with RCTIR? | Visible to Obliged Entities? | Visible via Legitimate Interest? | Notes |
|---|---|---|---|---|
| Full name and surnames | ✓ Yes | ✓ Yes | ✓ Yes | — |
| Full date of birth | ✓ Yes | ✓ Yes | ✗ No — month & year only | LI access restricted to month and year of birth |
| Identification documents and issuing country | ✓ Yes | ✓ Yes | ✗ No | — |
| Country of residence | ✓ Yes | ✓ Yes | ✓ Yes | — |
| Nationality | ✓ Yes | ✓ Yes | ✓ Yes | — |
| Email address | ✓ Yes | ✓ Yes | ✗ No | — |
| Nature and criterion of beneficial ownership | ✓ Yes | ✓ Yes | ✓ Yes | Ownership percentage or control basis |
| Intermediate ownership chain | ✗ No | ✗ No | ✗ No | Register records UBO only; chain mapping requires external sources |
| Historical UBO data | ✓ Yes — 10 years | ✓ Yes | ✗ Current only | Data retained 10 years post-termination; LI access limited to current information only |
| PEP status / sanctions overlay | ✗ No | ✗ No | ✗ No | Must be cross-checked from external sources |
Obliged Entities Cannot Rely Solely on the RCTIR
Spanish regulation explicitly states that obliged entities under Law 10/2010 — banks, notaries, lawyers, accountants — cannot rely exclusively on the RCTIR data to fulfil their customer due diligence obligations. They must still apply independent CDD measures and verify UBO information from the register against other sources. The RCTIR is a starting point, not a substitute for due diligence.
4. Who Can Access the Spanish RCTIR?
Spain's access model is officially based on legitimate interest — not a blanket public register, but also not a closed authority-only system. In practice, three categories get meaningful access. Everyone else faces a Spanish-language, Spanish-identity barrier that functions as an effective block.
2018
Order JUS/319/2018 creates the Registro de Titularidades Reales (RTR), linked to the Mercantile Registry. UBO filed annually with annual accounts.
July 2023
Royal Decree 609/2023 creates the RCTIR — a centralised, electronic national register aggregating UBO data from all sector registries. Ministry of Justice takes oversight.
19 September 2023
RCTIR goes operational. Sector registries have a 9-month transitional window to transmit existing data. Legitimate interest access framework applies from day one.
3 February 2025
Royal Decree 117/2024 activates. Form 036 now requires UBO disclosure to the Spanish Tax Agency for all corporate changes, creating a parallel filing obligation.
By July 2027
Spain must transpose the 6AMLD package, including harmonised legitimate interest access standards, mandatory machine-readable UBO data, and AMLA framework integration.
| Category | Access Level | Data Visible | Practical Notes |
|---|---|---|---|
| SEPBLAC (Financial Intelligence Unit), judicial authorities, tax authorities | Full — free & unrestricted | All data including full DOB, address, ID documents, email | Direct access; no prior conditions |
| Notaries and registrars | Full — free & unrestricted | All data | Integral to their oversight function under Spanish law |
| European fund management bodies | Full — free & unrestricted | All data | — |
| Obliged entities under Law 10/2010 (banks, lawyers, accountants, etc.) | Full — fee payable | All data: name, full DOB, ID, nationality, residence, email, nature of control | Must be accredited under Law 10/2010; access via RCTIR portal with digital certificate; fee applies per query |
| Persons/organisations with legitimate interest | Restricted — fee payable | Name, month & year of birth, country of residence, nationality, nature of control only | Must demonstrate legitimate interest; Spanish digital identity (DNI/NIE or empresa certificate) required; correspondence in Spanish only; processing time up to 6 months in practice |
| Media organisations and AML-related NGOs | Restricted — initial accreditation required | Same as legitimate interest subset | Must submit initial accreditation application via RCTIR portal; requires corporate digital certificate; all in Spanish |
| Foreign obliged entities without Spanish presence | Effectively blocked | None via official channel | No access route without a Spanish digital identity. BORIS interconnection allows Spanish authorities to share data with foreign counterparts but does not grant foreign entities direct RCTIR access. |
| General public | No open access | None | Spain did not provide unrestricted public access; legitimate interest required for all non-authority access |
Technically Open, Practically Closed for Foreign Entities
Spain's legitimate interest access model is formally inclusive — any person or organisation demonstrating legitimate interest can apply. But the requirement for a Spanish digital identity, Spanish-language correspondence, and a process that took Transparency International's Spanish arm six months to navigate — while receiving only partial data — means the RCTIR is functionally inaccessible to foreign compliance teams. This is one of the widest gaps between legal framework and operational reality in the EU's UBO landscape.
5. Cost and Availability
Company information in Spain flows through several sources with different costs and levels of ownership disclosure. The RCTIR provides the most direct UBO data but requires accreditation or a proven legitimate interest.
| Data Source | Cost | What You Get | UBO Data? |
|---|---|---|---|
| Registro Mercantil Central (rmc.es) | Free basic search; documents paid (€5–20) | Company name, NIF, legal form, directors, registered office, filing dates, annual accounts | ✗ None directly |
| Colegio de Registradores (registradores.org) | €5–15 per extract | Certified company extract: directors, registered capital, activity, address history | ✗ None directly |
| RCTIR — obliged entity access (Law 10/2010) | Fee per query (set by Ministry of Justice) | Full UBO data: name, full DOB, ID, nationality, residence, email, nature and criterion of control | ✓ Yes — full data |
| RCTIR — legitimate interest access | Fee payable; processing 1–6 months | Restricted: name, month & year of birth, country of residence, nationality, nature of control | ● Partial — restricted subset |
| Annual accounts (Cuentas anuales) | €5–15 per filing | Balance sheet, P&L, notes — all Spanish companies file annually at Mercantile Registry | ✗ None directly |
| Informe de Titularidad Real de Personas Jurídicas | Issued by company; no cost to requester | Official UBO declaration document: name, personal ID number, residence, nationality, DOB, ownership date and details | ✓ Yes — if provided voluntarily by counterparty |
What a Standard Mercantile Registry Extract Gives You
A certified extract from the Registro Mercantil Central or Colegio de Registradores — available at €5–20 with no login or accreditation — discloses: company name and NIF, legal form, registered office and address history, directors and administrators (named, with appointment and cessation dates), registered share capital, CNAE activity code, annual accounts filing history, and key corporate events (capital increases, mergers, dissolutions). This is the starting point for any Spanish KYB workflow — available immediately, internationally accessible, and usable without Spanish institutional standing.
No Public Shareholder Data for S.L. or S.A.
Unlike Italy's S.r.l. or the UK's Companies House, Spain does not publicly disclose shareholder registers. The libro de socios (S.L.) and libro de accionistas (S.A.) are private corporate documents. Directors and administrators are publicly visible in the Mercantile Registry — but ownership data above the UBO level is not publicly accessible for any standard Spanish entity type. This makes the RCTIR — or voluntary counterparty disclosure — the only routes to ownership information.
6. Penalties for Non-Compliance
Spain has one of the most consequential penalty regimes for UBO non-compliance in Europe, combining registry closure — which paralyses corporate operations — with large financial sanctions under Law 10/2010.
Registry closure
Article 378 of Commercial Registry Regulations: failure to file UBO information with annual accounts triggers closure of the registration sheet — the company cannot register any corporate acts
Up to €5M+
Serious infringements under Law 10/2010: fines up to the greater of 10% of annual turnover, amount of transaction plus 50%, three times profits, or €5,000,000
10 days
Deadline for commercial companies to notify any change in beneficial ownership to the Mercantile Registry from the date of becoming aware of it
Registry Closure Is the Most Impactful Consequence
The closure of the Mercantile Registry registration sheet under Article 378 is not just a fine — it is an operational paralysis. A company with a closed registration sheet cannot register director changes, capital increases, mergers, share transfers, or any other corporate act. This effectively freezes the company's ability to transact significant business until compliance is cured. For companies with active corporate governance — fundraising rounds, M&A, financing — this is a critical risk.
Under Law 10/2010, the penalty framework differentiates between very severe, severe, and minor breaches. Serious infringements — which include systemic failure to identify or register UBOs — also carry personal liability for directors, with fines from €3,000 to €10,000,000, reprimands, and disqualification from office. SEPBLAC, the Commercial Registry, and the courts all have sanctioning authority.
7. Key Legislation
| Legislation | Year | Key Provision |
|---|---|---|
| Law 10/2010 (AML Law) | 2010 / amended | Foundation of Spain's AML framework; defines titular real, obliged entities, CDD obligations, penalty framework (Articles 50–53) |
| Royal Decree 304/2014 | 2014 | Implementing regulation for Law 10/2010; detailed UBO identification criteria for different entity types |
| Order JUS/319/2018 | 2018 | Creates the Registro de Titularidades Reales linked to Mercantile Registry; annual UBO filing with annual accounts required |
| Royal Decree-Law 7/2021 | 2021 | Transposes 6AMLD; mandates creation of central single UBO register at Ministry of Justice level |
| Royal Decree 609/2023 | July 2023 | Creates the RCTIR; defines access tiers, data fields, sector registry transmission obligations, 9-month transitional period |
| RCTIR goes operational | 19 September 2023 | Central register opens. Legitimate interest access active from day one. |
| Royal Decree 117/2024 / Order HAC/1526/2024 | Effective 3 February 2025 | Requires UBO disclosure to Spanish Tax Agency via Form 036 for all corporate changes; parallel obligation alongside Mercantile Registry filing |
| 6AMLD transposition deadline | By July 2027 | Spain must implement harmonised legitimate interest access, machine-readable UBO data, AMLA framework; reform of RCTIR access model anticipated |
8. Upcoming Changes: The 2026–2027 Roadmap
1. 6AMLD transposition (by July 2027)
Spain must transpose the 6AMLD package by July 2027. Key changes include: harmonised legitimate interest access standards that will define who qualifies and under what conditions across all EU member states; mandatory machine-readable and API-accessible UBO data; AMLA oversight of the most significant cross-border obliged entities; and expanded reporting obligations for advisors. The RCTIR's current Spanish-identity-only access model will need to be reformed to comply.
2. RCTIR access reform — foreign entity access
The 6AMLD explicitly requires that legitimate interest access not be conditioned on national identity. Spain's current requirement for a Spanish digital certificate will need to be modified. This is the most significant structural change expected to the RCTIR before 2027 — and the change that will matter most for non-Spanish compliance teams.
3. BORIS interconnection and cross-border data sharing
The RCTIR is already connected to BORIS (Beneficial Ownership Registers Interconnection System), the EU's central UBO data exchange platform. As BORIS matures — and as 6AMLD harmonises access standards across member states — it will become possible for obliged entities in one member state to query UBO data from another member state's register through a single access point. This will reduce — but not eliminate — the Spanish-identity access barrier for foreign institutions.
4. AMLA direct supervision from 2028
The EU's Anti-Money Laundering Authority (AMLA), headquartered in Frankfurt, begins directly supervising the most significant cross-border financial institutions from 2028. AMLA will also coordinate national supervisors and set binding technical standards for UBO register interoperability. For Spain's RCTIR, this will drive API standardisation and data format alignment with the broader EU infrastructure.
9. The Real Challenges of Accessing Spanish UBO Data
9.1 Spanish digital identity is a hard barrier for foreign entities
The RCTIR portal requires a Spanish DNI, NIE, or corporate digital certificate to access. Non-Spanish entities and individuals without Spanish residency or corporate registration cannot obtain these credentials. This is not a bureaucratic inconvenience — it is a structural exclusion that makes the register operationally inaccessible for the majority of international compliance teams, regardless of the legitimacy of their interest.
9.2 Processing times are unpredictable and slow
Even for those who can demonstrate legitimate interest — such as journalists or civil society organisations with Spanish standing — processing times are unpredictable. Transparency International's Spanish subsidiary took six months to be granted access. This is not a workable timeframe for KYB due diligence or customer onboarding workflows.
9.3 Legitimate interest access returns restricted data only
Even if access is granted through the legitimate interest route, what you receive is a heavily restricted subset: name, month and year of birth (not full DOB), country of residence, nationality, and nature of control. No address, no identification document number, no email, no historical data. For compliance workflows that require detailed identity verification, this partial disclosure is often insufficient to complete a KYB check.
9.4 No public shareholder data for any standard Spanish entity
Spain provides no public shareholder register for S.L. or S.A. companies. Unlike Italy's S.r.l., where shareholders appear in public company extracts, or the UK's Companies House, where all shareholders above 25% are disclosed, Spain's corporate registers show directors and administrators publicly — but ownership data is entirely private. The RCTIR is the only route to UBO data for most entities, making the access barrier even more consequential.
9.5 Dual reporting obligation increases compliance complexity
Since February 2025, Spanish companies must file UBO data in two separate places — the Mercantile Registry and the Spanish Tax Agency — on different triggers and timelines. For foreign-owned Spanish subsidiaries where UBO changes are frequent — driven by group-level restructuring — this dual obligation creates a compliance surface that is easy to miss, particularly given the 10-day notification window for Mercantile Registry changes.
9.6 The register does not map ownership chains
The RCTIR records the natural person at the end of the ownership chain — not the intermediate corporate vehicles. A Spanish S.L. owned by a Dutch BV, owned by a UK holding company, controlled by a natural person in Germany: the RCTIR will show the German individual. It will not show the Dutch BV or UK holding company. Resolving the chain requires data from each intermediate jurisdiction.
9.7 Correspondence language and Spanish-only process
All RCTIR access requests and correspondence must be conducted in Spanish. For international compliance teams operating in English — or any other language — this adds a translation and operational layer that further slows the process and increases cost.
10. How to Verify a Spanish UBO Today: Step-by-Step
Spain's access barriers require a sequenced approach that starts with what is available outside the RCTIR and escalates only when necessary.
1
Pull the Mercantile Registry extract
Query the Registro Mercantil Central (rmc.es) or Colegio de Registradores (registradores.org) for a certified company extract. This gives you directors and administrators, registered capital, legal form, address history, and annual accounts filings — publicly available at low cost. No UBO data directly, but directors are named and may be the assimilated UBOs for simpler structures.
2
Review annual accounts for ownership indicators
Annual accounts filed at the Mercantile Registry are publicly accessible. Notes to accounts often include information about parent companies, group structures, and related party relationships — particularly for entities that are part of larger groups. This can identify the immediate parent without RCTIR access.
3
Map the ownership chain above the Spanish entity
If the Spanish entity is owned by a foreign parent — a UK holding company, a German GmbH, a French SAS — the UBO may be identifiable through the parent's home registry where data is more accessible. Zavia.ai is a beneficial ownership intelligence platform that connects to 400+ government registries in 173 countries and links companies and people through a cross-border ownership graph. Its API traverses the chain above any Spanish entity automatically, identifying the ultimate parent and surfacing UBO data from the most accessible jurisdiction — without requiring a Spanish digital certificate.
4
Request the Informe de Titularidad Real from the counterparty
Request a certified Informe de Titularidad Real de Personas Jurídicas directly from the Spanish entity. This official document — containing the UBO's name, personal ID, residence, nationality, DOB, and nature of control — can be issued by the company and is widely used by Spanish banks and notaries as part of KYB onboarding. It is the most practical route for foreign compliance teams without RCTIR access.
5
Cross-check against sanctions and PEP databases
Once a natural person is identified as UBO, screen against EU, OFAC, and UN sanctions lists and PEP databases. Spain's RCTIR carries no sanctions flags — this step requires an external overlay. Zavia.ai's screening layer runs sanctions checks as part of the same ownership query, so you don't need a separate tool for this step.
6
Escalate to RCTIR access if high-risk and unresolved
If steps 1–5 do not resolve the UBO and the entity is high-risk, consider: (a) engaging a Spanish law firm or AML-accredited intermediary with the required digital credentials to access the RCTIR on your behalf, or (b) pursuing a direct legitimate interest application if your organisation can obtain a Spanish corporate digital certificate and conduct correspondence in Spanish. Expect processing times of weeks to months.
Monitor for the 10-Day Change Notification Window
Spanish commercial companies must notify UBO changes to the Mercantile Registry within 10 days of becoming aware of them — one of the shortest deadlines in the EU. For foreign-owned Spanish subsidiaries where group restructuring is frequent, build automated triggers into your compliance workflow to track this obligation. Missing the deadline risks registry closure, which is operationally catastrophic.
11. Accessing Spanish Company Data via Zavia.ai
Spain's RCTIR is technically accessible — but the Spanish digital identity requirement, Spanish-language process, and multi-month processing times mean it is operationally closed for the vast majority of international compliance teams. And even when access is granted, the legitimate interest subset excludes full DOB, address, and identification documents — the exact fields needed for robust KYB verification.
As covered in the workflow above, Zavia.ai bypasses this barrier by connecting directly to the Registro Mercantil Central and the Colegio de Registradores — the primary sources of Spanish company data — and combining that with a cross-border ownership graph that traces the chain above any Spanish entity to its ultimate parent. The result is structured ownership intelligence delivered through a single API endpoint or bulk file, without requiring a Spanish digital certificate or Spanish-language correspondence.
Spain shareholder data access: how it compares across Europe
Spain stands out as one of the least transparent jurisdictions for shareholder data among major EU economies — no public shareholder register for any standard entity type, and a UBO register that is effectively inaccessible for foreign compliance teams.

Spain Is the Hardest Major EU Market for Foreign UBO Access
Of the six major EU/European jurisdictions covered in this series, Spain is the most operationally challenging for foreign compliance teams. It has no public shareholder data, a UBO register that requires a Spanish national identity to access, a 1–6 month processing window for legitimate interest requests, and correspondence restricted to Spanish. The gap between what the law provides and what is operationally possible is wider in Spain than in any other comparable jurisdiction.

How the ownership graph works for Spanish entities
Spain's structural access barrier makes the ownership graph approach especially valuable. Most significant Spanish entities are subsidiaries of foreign groups — multinational corporations with German, French, UK, or US parent companies where beneficial ownership data is more accessible or even fully public. By tracing the chain upward above the Spanish entity, Zavia.ai identifies the ultimate parent and the jurisdiction where UBO data is most available — turning a blocked RCTIR query into a solvable cross-border ownership problem.
400+ Government Registries. Linked Across People and Companies.
Zavia.ai sources data directly from 400+ government registries across 173 countries — company records, director appointments, shareholder filings, and ownership data from primary sources, not aggregators. These data points are linked through an ownership graph that maps subsidiary-to-parent relationships, shared directorships, and cross-border control chains. Query a Spanish S.L. and the graph returns not just the Spanish record — but the full ownership structure above and below it, across every jurisdiction where data is available.
Where Spain's RCTIR is inaccessible, the ownership graph surfaces UBO data through the most accessible node in the chain — whether that's UK Companies House, the German Handelsregister, or the French INPI — combined with Spanish company and director data to produce a complete, primary-source ownership picture.

12. Frequently Asked Questions
Yes. Spain's Registro Central de Titularidades Reales (RCTIR) was created by Royal Decree 609/2023 and became operational on 19 September 2023. It is a central, electronic register managed by the Ministry of Justice that consolidates beneficial ownership data from multiple sector-specific registries including the Mercantile Registry, Foundations Registry, and Associations Registry. It is technically accessible via legitimate interest but practically inaccessible for foreign entities without a Spanish digital identity.
Under Article 4 of Law 10/2010, a titular real is any natural person who directly or indirectly holds more than 25% of a company's share capital or voting rights, or who exercises control through other means. If no natural person meets these criteria, the senior managers (administradores) are deemed the assimilated UBOs (titulares reales asimilados). Where the governing body is a legal entity, its natural person representative is designated.
In theory, yes — the RCTIR allows access for anyone demonstrating legitimate interest. In practice, access requires a Spanish digital identity (DNI, NIE, or corporate digital certificate), and all correspondence must be conducted in Spanish. As of early 2026, this makes the register virtually inaccessible to foreign entities without Spanish institutional standing. Even Transparency International's Spanish subsidiary took six months to be granted access — and received only partial data. The 6AMLD transposition required by July 2027 is expected to reform these access conditions.
Under Article 5.3 of Royal Decree 609/2023, legitimate interest access is restricted to: name and surnames, month and year of birth (not full date), country of residence, nationality, and the nature of the beneficial ownership. Full personal data — full date of birth, home address, identification documents, email address — is reserved for competent authorities and accredited obliged entities under Law 10/2010.
Failure to file UBO information with the Mercantile Registry triggers closure of the registration sheet under Article 378 of the Commercial Registry Regulations — freezing all corporate acts including director changes, capital increases, and share transfers. Under Law 10/2010, serious infringements carry fines from €60,000 up to the greater of: 10% of annual turnover, the transaction amount plus 50%, three times the profits derived, or €5,000,000. Directors face personal liability from €3,000 to €10,000,000, plus possible disqualification from office.
Spanish commercial companies must file UBO information annually alongside their annual accounts at the Mercantile Registry — generally by 30 July for December year-end companies. Any change in beneficial ownership must be notified to the Mercantile Registry within 10 days of becoming aware of it. Since 3 February 2025, UBO disclosure is also required when filing Form 036 to the Spanish Tax Agency for any corporate change, including modification of the governing body or a change of registered address.
No — Spain does not publicly disclose shareholder registers for any standard entity type. The libro de socios (S.L.) and libro de accionistas (S.A.) are private corporate documents. Directors and administrators are publicly visible in the Mercantile Registry extracts, but ownership data is not publicly accessible. This makes Spain one of the least transparent jurisdictions for shareholder data among major EU economies, and makes the RCTIR — or voluntary counterparty disclosure — the only routes to ownership information.
From 3 February 2025, Royal Decree 117/2024 (implemented through Order HAC/1526/2024) requires companies to also declare their UBO to the Spanish Tax Agency (Agencia Tributaria) every time they file a Form 036 for a corporate change — such as modification of the governing body, change of registered address, or other significant corporate transactions. This creates a parallel UBO reporting obligation alongside the existing annual Mercantile Registry filing, significantly increasing the compliance surface for companies with frequent structural changes.
SEPBLAC (Servicio Ejecutivo de la Comisión de Prevención del Blanqueo de Capitales e Infracciones Monetarias) is Spain's financial intelligence unit, operating within the Bank of Spain. It supervises AML compliance for obliged entities, has full unrestricted access to the RCTIR, and is one of the main enforcement authorities for UBO compliance under Law 10/2010. It also coordinates international information exchange and is Spain's representative in the Egmont Group of financial intelligence units.
Yes. The RCTIR is connected to BORIS (Beneficial Ownership Registers Interconnection System), the EU's central UBO data exchange platform. This allows Spanish authorities and subsequently obliged entities to access beneficial ownership information from other EU member states. However, BORIS access for obliged entities is still developing, and it does not grant foreign entities direct access to the RCTIR itself — the Spanish digital identity requirement remains in place for direct RCTIR queries.
Spain's RCTIR is inaccessible for most foreign compliance teams, and no public shareholder data exists for Spanish entities. The most effective alternative is to trace the ownership chain above the Spanish entity to its ultimate parent — typically in a jurisdiction where beneficial ownership data is more accessible. Zavia.ai's ownership graph maps this chain automatically across 173 countries, enabling UBO resolution through the UK Companies House, the German Handelsregister, the French INPI, or other accessible registries — without requiring a Spanish digital identity or Spanish-language correspondence.
