Deed of Incorporation SA Spain (Escritura de Constitución de Sociedad Anónima)

A Deed of Incorporation SA Spain (Escritura Pública de Constitución de Sociedad Anónima) is the notarial instrument through which a Sociedad Anónima (SA) — Spain's public limited company form — is legally constituted and brought into existence as a legal person (persona jurídica), governed by Real Decreto Legislativo 1/2010, de 2 de julio, por el que se aprueba el texto refundido de la Ley de Sociedades de Capital (LSC), Article 22, which requires all capital companies to be constituted through a public deed (escritura pública) executed before a Notario de España and subsequently registered in the Registro Mercantil.

The Sociedad Anónima is one of Spain's two principal commercial company forms — alongside the Sociedad de Responsabilidad Limitada (SRL/SL) — regulated by the LSC. The SA is distinguished by its minimum share capital requirement of €60,000 under Article 4.2 LSC, fully subscribed and at least 25% paid up at constitution (Article 79 LSC), and by the transferability of its shares (acciones) by delivery or endorsement without restriction by third parties, making the SA the preferred vehicle for large enterprises, listed companies (sociedades cotizadas), and joint ventures requiring open transferability of ownership.

The LSC Chapter I of Title I (Articles 19 through 28) governs the constitution process. Article 20 LSC establishes that the SA acquires legal personality (personalidad jurídica) from the moment of registration in the Registro Mercantil — prior to registration, the SA is treated as a sociedad en formación (company in formation) under Articles 36 through 40 LSC, with promoters and founders jointly liable for pre-incorporation obligations. The Escritura de Constitución must contain the Estatutos Sociales (Articles of Association) as required by Article 22 LSC — typically annexed to the deed — and must be registered within 2 months of execution under Article 27 LSC, or the incorporators may dissolve the company and recover their contributions.

The Registro Mercantil (Commercial Registry), governed by the Código de Comercio (Real Decreto de 22 de agosto de 1885) and the Reglamento del Registro Mercantil (Real Decreto 1784/1996), assigns the SA a registration number (número de hoja registral) and publishes a notice in the Boletín Oficial del Registro Mercantil (BORME). The company must also obtain a Número de Identificación Fiscal (NIF) for the company from the Agencia Tributaria and register for the relevant tax obligations — Impuesto de Sociedades (corporate income tax) under Ley 27/2014, Impuesto sobre el Valor Añadido (IVA) under Ley 37/1992, and, if applicable, Impuesto de Actividades Económicas (IAE) under the Ley de Haciendas Locales.

The SA's share capital (capital social) is divided into shares (acciones) — nominativas (registered) or al portador (bearer, currently restricted by Ley 10/2010 de blanqueo de capitales). The value of shares may be expressed as nominal value (valor nominal) or as a fraction of the capital without nominal value (acciones sin valor nominal — permitted since Real Decreto-ley 13/2010). Shares may be ordinary (acciones ordinarias) or privileged (acciones privilegiadas) with economic or political rights under Articles 94 and 96 LSC. Non-monetary contributions (aportaciones no dinerarias) — such as real property, intellectual property rights, or machinery — must be valued by an independent expert (experto independiente) appointed by the Registro Mercantil under Article 67 LSC.

The governance structure of the SA is established in the Estatutos: the Junta General de Accionistas (General Meeting) as the supreme governing body under Articles 159 et seq. LSC; and the management body (órgano de administración) — which may be a sole administrator (administrador único), joint administrators (administradores solidarios or mancomunados), or a board of directors (consejo de administración) under Articles 209 et seq. LSC. Listed SAs are additionally subject to the Ley del Mercado de Valores (Ley 6/2023) and the CNMV (Comisión Nacional del Mercado de Valores) regulations.

A Deed of Incorporation SA Spain is required whenever founders (fundadores) wish to establish a Sociedad Anónima — the public limited company form under the Ley de Sociedades de Capital (LSC RDL 1/2010) — as opposed to the more commonly used Sociedad de Responsabilidad Limitada (SL).

The Escritura de Constitución SA is needed when founders wish to raise capital through the public or private issuance of shares — the SA structure allows for a wide shareholder base and supports eventual listing on the Bolsa de Valores (stock exchange — managed by Bolsas y Mercados Españoles, BME) or the Mercado Alternativo Bursátil (MAB), which are only available to SAs under the Ley del Mercado de Valores (Ley 6/2023).

The deed is required when establishing a joint venture between Spanish and foreign corporate investors who require a vehicle with freely transferable shares and governed by the internationally recognised SA / public company framework — the SA structure is generally preferred over the SL for institutional shareholders, private equity funds, and transactions subject to foreign investment regulations under Ley 19/2003 and Real Decreto 664/1999.

An SA incorporation is needed when a company must comply with legal reserve requirements that are typically associated with the SA form — Article 274 LSC requires the SA to allocate 10% of annual profits to a legal reserve (reserva legal) until the reserve reaches 20% of the share capital, providing additional creditor protection compared to smaller SL structures.

The Escritura de Constitución SA is required when promoters (promotores) use the successive incorporation process (constitución por suscripción pública) under Articles 41 through 55 LSC — where shares are offered to the public before the company is formally incorporated, requiring regulatory compliance with the Comisión Nacional del Mercado de Valores (CNMV) and the publication of a prospectus (folleto informativo) under Reglamento (UE) 2017/1129.

A Deed of Incorporation SA is needed when the business activity requires an SA by law — certain regulated sectors in Spain mandate the SA form for licensed operators, including insurance companies (aseguradoras) under Ley 20/2015 de ordenación, supervisión y solvencia de las entidades aseguradoras, investment firms (empresas de servicios de inversión) under Ley 6/2023, and certain banking entities under Ley 10/2014 de ordenación, supervisión y solvencia de entidades de crédito.

A valid Deed of Incorporation SA Spain under LSC Real Decreto Legislativo 1/2010 Article 22 must contain the following essential elements to be accepted for registration in the Registro Mercantil.

Identification of Founders (Fundadores): Full name, DNI/NIE/passport, nationality, civil status, and address of all founding individuals; or NIF, Registro Mercantil registration, and representative details for founding legal entities. Article 21 LSC allows both individuals and legal entities to act as founders. A sole-founder SA (sociedad anónima unipersonal) is permitted under Article 12 LSC — the unipersonal nature must be stated in the deed and registered.

Company Name (Denominación Social): The company's chosen name followed by the designation 'Sociedad Anónima' or its abbreviation 'S.A.' under Article 6 LSC. The name must be unique — verified through the Registro Mercantil Central's online name reservation service (certificación negativa de denominación) — and must not infringe third-party trade marks registered with the Oficina Española de Patentes y Marcas (OEPM).

Registered Address (Domicilio Social): The company's registered office in Spain under Article 9 LSC — a physical address within Spanish territory. The domicilio social determines the competent Registro Mercantil and the courts with jurisdiction over the company. Changes require a deed and re-registration.

Corporate Object (Objeto Social): A clear, precise description of the company's business activities (actividades) under Article 23(b) LSC. Overly broad objects may be rejected by the Registro Mercantil — the description should correspond to the company's CNAE code (Clasificación Nacional de Actividades Económicas) for tax registration purposes.

Share Capital and Shares: The total subscribed share capital (capital social suscrito) — minimum €60,000 under Article 4.2 LSC — and the amount paid up at incorporation (minimum 25% of total subscribed capital under Article 79 LSC). The number of shares (número de acciones), nominal value per share (valor nominal), and class of shares (class A ordinary, class B privileged, etc.) must be stated under Articles 23(c) and 94 LSC.

Shareholder Subscription and Payment: Each founder's subscription of shares and payment made — either monetary contributions (aportaciones dinerarias) evidenced by bank certificate (certificado de ingreso bancario) or non-monetary contributions (aportaciones no dinerarias) valued by an experto independiente appointed by the Registro Mercantil under Article 67 LSC.

Management Structure: The management body (órgano de administración) chosen — sole administrator, joint administrators, or board of directors (consejo de administración) — with the names, DNI/NIF, and acceptance of appointment of the first administrators under Article 22(1)(e) LSC. Board members must be registered in the Registro Mercantil. Directors of listed SAs must also comply with the Código de Buen Gobierno (Corporate Governance Code) published by the CNMV.

Statutory Duration: The duration of the company — indefinite (tiempo indefinido) or for a specific term under Article 23(e) LSC. Most Spanish companies are incorporated with indefinite duration.

Anti-Money Laundering Declaration: A declaration of the beneficial owners (titulares reales) under Ley 10/2010 de prevención del blanqueo de capitales, required for all new companies — founders must declare whether any individual holds or controls more than 25% of shares or voting rights (Real Decreto 304/2014).

Annexed Estatutos Sociales: The Estatutos Sociales (Articles of Association) under Article 22 LSC must be included as an annex to the Escritura de Constitución. The estatutos govern the internal organisation, share transfers, corporate governance, and dissolution procedures.

Forms-legal.com provides this Deed of Incorporation SA Spain template as a preparatory reference. The Escritura de Constitución must be executed before a Notario de España (Consejo General del Notariado) and registered in the Registro Mercantil within 2 months under Article 27 LSC. Engagement of a specialist abogado mercantilista or gestor administrativo is strongly recommended for the full incorporation process, including Agencia Tributaria NIF registration, Seguridad Social employer registration with the TGSS, and municipal licence (licencia de apertura) applications before the Ayuntamiento.
