Commercial Registry (Registro Mercantil)

What Is the Registro Mercantil?

The Registro Mercantil is Spain’s official commercial registry — the public record of all companies and merchants operating in Spain. It is organised provincially (each province has its own registry, with Madrid and Barcelona being the largest) and supervised by the Registradores de España under the jurisdiction of the Ministry of Justice. There is also a Registro Mercantil Central in Madrid, which manages nationwide name reservations and the central archive.

The Registro Mercantil serves three core functions:

1. Constitutive function: For most corporate acts (incorporation, capital increases, mergers), registration in the Registro Mercantil is legally required for the act to be fully effective against third parties.
2. Publicity function: All registered information is publicly accessible, enabling anyone to verify a company’s legal existence, ownership structure, administrators, and financial condition.
3. Filing repository: Annual accounts must be deposited at the registry, creating a public financial record.

What Gets Registered?

The main items that must be registered include:

• Incorporation: The public deed of incorporation (escritura de constitución) and articles of association (estatutos sociales).
• Appointment and resignation of administrators and directors — anyone dealing with a company needs to verify that the administrator they are contracting with is duly registered.
• Capital increases and decreases (ampliaciones y reducciones de capital).
• Registered office changes.
• Mergers, splits, and transformations.
• Liquidation and dissolution.
• Annual accounts (Cuentas Anuales) — SL and SA companies must deposit their annual accounts within one month of their approval at the General Meeting (typically by 31 July for companies with a December year-end).
• Powers of attorney (poderes notariales) granted by the company.

Branches of Foreign Companies

Foreign companies operating in Spain through a branch (sucursal) — rather than a subsidiary — must also register the branch at the relevant provincial Registro Mercantil, submitting authenticated and translated copies of the parent’s constitution documents.

Public Access and Searching the Registry

Anyone can search the Registro Mercantil through:

• FLEI (Fichero Localizador de Entidades Inscritas): Name and NIF searches to identify the relevant provincial registry.
• Registro Mercantil Central online: Summary information on companies.
• Commercial data providers (Axesor, Informa, Einforma): Aggregated company data including financial summaries derived from deposited accounts.

Conducting a Registro Mercantil search is a standard step in any due diligence, contract negotiation, or credit assessment in Spain.

Penalties for Not Filing Annual Accounts

Companies that fail to deposit their annual accounts within the statutory deadline face a closure of the registry sheet (cierre registral): no new entries can be recorded until the overdue accounts are filed and a penalty paid. This effectively blocks the company from registering changes to directors, capital, or registered office — a significant operational problem.

The AEAT also cross-references Registro Mercantil filings against tax returns and may initiate investigations when companies stop filing accounts.
