What is the Registro Mercantil and How to Register a Company in Spain
Lawants Guide · Company Registration in Spain Registering a company in Spain takes 7 to 10 working days from the receipt of complete documentation. The process itself is straightforward. What determines the actual timeline is not the registry, but what happens before it: the name reservation, the preparation of documentation by foreign shareholders, and the notarial deed. When these steps are planned in the correct sequence, the registration runs cleanly. When they are not, the registry is the last thing to slow it down.
Spain’s official company register is the Registro Mercantil. Every Spanish company, from a Sociedad Limitada to a branch office, must register here to acquire legal personality and the right to operate commercially. The register is public, though detailed company data requires payment of a fee per query. For foreign entrepreneurs, the registration process also requires obtaining a Spanish tax identification number for the company, and a Spanish NIE for any individual founders or administrators. These are not bureaucratic afterthoughts: they are prerequisites that must be in place before the notary appointment can be scheduled.

What Is the Spanish Company Register (Registro Mercantil)?
The Registro Mercantil is Spain’s official commercial register, the legal equivalent of Companies House in the UK or the Handelsregister in Germany.
Every Spanish company must be registered here before it can legally operate, issue invoices, open a bank account under its own name, or be recognised as a separate legal entity from its shareholders.
The Registro Mercantil operates at two levels. The Registro Mercantil Central (Central Mercantile Registry) handles company name reservations for the entire country and maintains a central database. The Registro Mercantil Provincial (provincial registries, one per province) is where company deeds are actually registered after the notary appointment. When a company is incorporated in Barcelona, the deed is filed with the Registro Mercantil of Barcelona. When it operates in Madrid, with Madrid’s registry.
Contrary to what many foreign founders believe, the Registro Mercantil does not approve business projects. It simply records companies that have already completed the legal incorporation process. The registry is the endpoint, not the gatekeeper.
The registry is a public record, though access to detailed company information requires payment. The official online portal is sede.registradores.org, where company excerpts, director details, and annual accounts can be requested for a fee. Free searches return only basic confirmation of a company’s existence and registration number. For a full guide to searching the Spanish register, see our company search in Spain guide.
The registry is not where the process slows down. It is where the preparation either pays off or does not.
Lawants manages the full registration sequence for foreign entrepreneurs in Spain, from name reservation and NIE and NIF applications through the notarial deed, registry filing, and tax registration, so each step is in place before the next one needs it.

Choosing and Reserving a Company Name in Spain
The company name (denominación social) in Spain is not just a commercial identity. It is a legal element that must be unique within the national register, comply with Spanish naming rules, and be reserved before the incorporation deed can be drafted. Most foreign founders underestimate how specific the rules are and how much time can be lost if the first name choice is rejected.
Rules for Company Names in Spain
- No identical or confusingly similar names. The Registro Mercantil Central will reject any name that is already registered or that could be confused with an existing company. This applies to phonetic similarity, abbreviated forms, and names that differ only by punctuation or minor spelling variations. A search of the register before submitting is essential.
- The legal form must be included. The company name must end with the legal form designation. For a Sociedad Limitada: “S.L.”, “S.L.U.” (for sole-member companies), or the full “Sociedad Limitada”. For an S.A.: “S.A.” or “Sociedad Anónima”. The designation cannot be omitted.
- Geographic names require care. Names that imply official or institutional status, or that suggest a connection to Spain’s government or regions without authorisation, are rejected. Names containing geographical references to autonomous communities or municipalities also require specific approval in some cases.
- Foreign-language names are permitted, including names in English or other languages, provided they do not conflict with existing registrations and do not violate public order or good customs under Spanish law.
- Names suggesting regulated activities require verification. A name that implies the company operates in banking, insurance, or other regulated sectors may trigger additional scrutiny or require sector-specific authorisation before registration.
How the Name Reservation Works
Name reservation is submitted to the Registro Mercantil Central in Madrid, either online via the official portal or through a notary. The reservation is valid for six months from the date of issue and must be renewed or used before it expires. Once a name is reserved, it is blocked from use by any other company for the duration of the reservation.
The most efficient approach is to submit up to five name alternatives simultaneously, ranked in order of preference. The registry assigns the first available name from the list. This avoids the situation where a single-choice submission is rejected and the entire preparation process must pause while a new name is proposed, checked informally, and resubmitted. In our experience, founders who submit one name at a time and receive a rejection have typically lost five to ten working days that the five-alternative approach would have avoided.
The name reservation certificate from the Registro Mercantil Central is a mandatory exhibit for the notary. Without it, the deed cannot be executed. The reservation takes 2 to 5 working days and should be submitted simultaneously with NIE and NIF applications, not after them.
How to Register a Company in Spain: Step-by-Step
The registration process covers both the legal incorporation steps and the administrative requirements that must be satisfied before the notary appointment. For foreign entrepreneurs, several of these prerequisites run in parallel rather than sequentially: starting them in the wrong order is the most common reason a registration that should take two weeks takes two months.
✅ NIE for individual founders
✅ Corporate NIF for foreign shareholders
✅ Draft power of attorney
✅ Articles of Association drafting
🔒 Notarial deed → needs name + NIF + NIE + bank cert
🔒 Registry filing → needs executed deed
🔒 Tax activation → needs definitive NIF
- Reserve the company name (denominación social). Submit a request to the Registro Mercantil Central to confirm that no other company is already registered under the same name or a confusingly similar one. The reservation is valid for six months and is a prerequisite for the notarial deed. Name reservation typically takes 2 to 5 working days. Up to five name alternatives can be submitted simultaneously; the first available one is reserved.
- Obtain a Spanish NIE for individual founders and administrators. Every individual who will appear in the deed of incorporation, whether as a shareholder or as an administrator, must have a Spanish NIE (Número de Identificación de Extranjero) before the notary appointment. EU citizens can apply at a Spanish police station or consulate; non-EU nationals may need to apply from their country of residence. This step should start on the same day as the name reservation, not after it.
- Obtain a Spanish NIF for foreign corporate shareholders. If a foreign company is a shareholder in the new Spanish entity, that company must obtain its own Spanish tax identification number (NIF) using Form EX-15, submitted to the Agencia Tributaria with supporting documentation and a representative with a Spanish NIE. This is one of the most commonly underestimated steps: processing can take two to four weeks, and the deed cannot be signed without it.
- Open a corporate bank account and deposit the share capital. For an S.L., the minimum €3,000 must be deposited in an account opened in the company’s name (before it formally exists). The bank issues a deposit certificate confirming the capital has been received, which is a required exhibit for the notary. Bank account opening for foreign-owned entities with non-resident shareholders involves KYC verification that can take one to four weeks depending on the bank and the shareholder profile.
- Draft the Articles of Association (Estatutos Sociales). The deed of incorporation includes the company name, registered office, business purpose, share capital and distribution, management structure, and decision-making procedures. The articles define the governance of the company and any shareholder arrangements. For customised structures, this draft is prepared before the notary appointment. Standard bylaws are available for S.L.s incorporating via CIRCE.
- Execute the deed of incorporation before a Spanish notary. All shareholders, or their duly authorised representatives via a power of attorney with apostille certification, sign the deed before the notary. The notary verifies all documentation, confirms the capital deposit certificate, and issues the executed deed. A provisional NIF is simultaneously requested from the Agencia Tributaria. The notary also files the AJD tax (Impuesto de Actos Jurídicos Documentados) on the company’s behalf.
- Register the deed with the Registro Mercantil Provincial. The executed deed is submitted to the provincial registry of the company’s registered office. Processing takes up to 15 working days. Upon registration, the company acquires full legal personality and the definitive NIF is issued. The registry publishes the incorporation in the BORME (Boletín Oficial del Registro Mercantil), Spain’s official commercial gazette.
- Complete tax and administrative registrations. Register with the Agencia Tributaria for corporate income tax and VAT (Modelo 036), register for social security if the company will employ staff, and obtain any sector-specific licenses required for the business activity. These steps can begin after registry confirmation but should be planned in advance to avoid operational delays.
Costs of Company Registration in Spain
The official costs of registering a company in Spain are modest relative to other European jurisdictions. They are also rarely the number that surprises foreign entrepreneurs; the unexpected costs are almost always in the preparatory steps rather than the registration itself.
Two things about the cost table below are worth stating clearly before reading it. First, the €3,000 minimum share capital for an S.L. is not a registration fee: it is deposited into the company’s bank account and becomes available to the company for operational use the moment the company begins trading. It is a company asset, not a sunk cost. Second, the AJD tax (Impuesto sobre Actos Jurídicos Documentados) was exempted for S.L. and S.A. incorporations in 2010 and does not apply to standard company formation.
| Cost item | Indicative range |
|---|---|
| Minimum share capital (S.L.) | €3,000 (fully paid at incorporation; becomes company asset) |
| Notary fees | €150 to €800 (scaled to share capital and deed complexity) |
| Mercantile Registry fees | €100 to €400 |
| Name reservation fee | Small administrative fee at the Central Registry |
| AJD tax (Impuesto de Actos Jurídicos Documentados) | Exempt for S.L. and S.A. since 2010 |
| NIE application | Modest official fee; can be requested at a Spanish consulate or in Spain |
Share capital is not a cost: it is a company asset available for operational use from the moment the company begins trading. Notary and registry fees are the only true registration costs. Professional fees for legal and accounting assistance vary by firm and are not included above.
For qualifying innovative startups certified under the Startups Law (Law 28/2022), notarial and registry fees are waived when using standard bylaws via the CIRCE online platform. Qualifying startups using CIRCE can complete the electronic incorporation in as little as six working hours.
How to Search for a Company in the Spanish Register
The Registro Mercantil is a public record, but it is not freely searchable in the way that some other European registries are. Spain moved its detailed company data behind a paywall in 2011. Free searches confirm a company’s existence and NIF; detailed information requires a paid excerpt.
The official search portal is sede.registradores.org. A company excerpt (nota simple) requested by company name or NIF returns directors, share capital, annual accounts, and registered acts published in the BORME. Shareholder identities are not publicly disclosed for S.L. companies, which is a meaningful privacy advantage specific to Spanish company law.

Common Mistakes in Company Registration in Spain
In over twenty years, Lawants has seen registrations delayed for the same reasons again and again. None of them arise from the registry being difficult. They arise from steps that were started in the wrong order, or skipped entirely on the assumption that they could be handled later.
| Mistake | Why it causes delays |
|---|---|
| Scheduling the notary before obtaining the corporate NIF | The NIF for a foreign corporate shareholder takes 2 to 4 weeks. Without it, the notary appointment must be postponed, and everything else pauses with it. |
| Waiting for the name reservation before starting the NIE | The NIE application is independent of the name. Starting it the same day as the name reservation saves 2 to 5 weeks that would otherwise be added sequentially. |
| Preparing a power of attorney without apostille | A PoA executed abroad without Hague Convention apostille certification cannot be used at the notary. It must be redone, which means restarting that process from the country of origin. |
| Choosing a corporate purpose that is too broad or too narrow | An overly generic purpose may be rejected by the registry. An overly narrow one will require a deed amendment and a second registry filing the moment the business expands. |
| Opening the bank account too late | Bank KYC for non-resident shareholders can take 1 to 4 weeks. Without the bank’s capital deposit certificate, the notary cannot execute the deed. |
Common Delays in Spanish Company Registration for Foreign Entrepreneurs
The registration process itself is predictable. Almost every delay we encounter comes from the same handful of sources, all of which sit upstream of the notary appointment, not at the registry.
The foreign shareholder’s NIF: the step that stops everything
When the shareholder of the new Spanish company is a foreign legal entity, that company must obtain its own Spanish NIF before the incorporation deed can be signed. The application uses Form EX-15, requires specific documentation about the foreign company, and needs a representative with a Spanish NIE to submit it. Processing takes two to four weeks. It cannot be done after the notary appointment. We regularly see projects where the foreign company starts the NIF application only after the name has been reserved and the notary has been scheduled, which means the appointment must be postponed.
The same applies to NIEs for individual founders who are not yet in Spain: the NIE application should start the same day as the name reservation, not when everything else is ready.
We initiate the NIF and NIE applications in parallel with the name reservation from day one. The documentation required for each process overlaps substantially, so preparing them together reduces both total time and administrative back-and-forth with the authorities.
A registration that takes ten working days when correctly prepared takes six to eight weeks when it is not.
- Bank KYC for non-resident shareholders. Banks in Spain apply rigorous KYC procedures to non-resident corporate shareholders. Account opening for a company with a foreign majority owner can take one to four weeks, and some banks refuse to open accounts for certain corporate structures without additional documentation or a local connection.
- Power of attorney without apostille. If a founder cannot attend the notary appointment in person, a power of attorney (PoA) is needed. For PoAs executed abroad, apostille certification under the Hague Convention is required, plus a sworn translation into Spanish. A PoA that arrives without apostille or with an incorrect translation cannot be used at the notary and must be redone.
- Business purpose too broad or too narrow. The corporate purpose stated in the Articles of Association must be specific enough to be legally valid but broad enough to cover the actual and planned activities of the business. A purpose that is too generic may be rejected by the registry; one that is too narrow will require a deed amendment and additional registry filing to accommodate new activities.
- Name unavailability after preparation has begun. Name reservations are valid for six months but can be challenged if a sufficiently similar name already exists. Submitting five alternatives simultaneously at the start, rather than one at a time sequentially, avoids restarting this step while other preparation is already underway.
Most delays do not come from the registry. They come from documentation that was prepared in the wrong sequence.
Lawants coordinates the full documentation sequence for foreign company registration in Spain, with NIE, NIF, bank account, and power of attorney all running in parallel from day one, not sequentially after each other.

Can I Register a Company in Spain Remotely?
Yes. Company registration in Spain can be completed without the founder being physically present in Spain, through a combination of power of attorney for the notary appointment and online tax registration processes. In our experience, the fully remote route is entirely viable for foreign entrepreneurs who prepare the documentation correctly from the start.
The power of attorney must be executed before a notary in the founder’s country of residence, apostilled under the Hague Convention, and accompanied by a sworn Spanish translation. The notary in Spain then acts on the founder’s behalf to execute the deed of incorporation, and all subsequent registrations can be handled by the appointed representative in Spain.
The one limitation of the remote route is the bank account: some Spanish banks require at least one in-person visit for account opening procedures, particularly for non-resident corporate shareholders. Where this is a constraint, alternative banking solutions or prior coordination with the bank can reduce the need for physical presence.
Why Foreign Entrepreneurs Register Their Company in Spain with Lawants
Most foreign entrepreneurs who contact us about company registration in Spain have already decided they want to incorporate. The question is not whether to register, but how to do it in a way that does not lose weeks to documentation issues that were avoidable from the start. In over twenty years working exclusively with foreign companies in Spain, we have seen registrations delayed for the same reasons again and again: a corporate NIF started too late, a power of attorney that arrived without apostille, a bank account opened only after the notary appointment was already scheduled.
Lawants works exclusively with foreign companies and entrepreneurs entering the Spanish market, with lawyers and tax advisors operating under one roof. For company registration, that matters because the legal steps, the tax registrations, and the identification requirements for foreign founders and shareholders are not independent processes: they share documentation, they have dependencies between them, and a delay in one creates a delay in all the others.
The Registro Mercantil does not slow down a well-prepared registration. It confirms it. The preparation is what Lawants does before any appointment is booked.
Company registration in Spain takes 7 to 10 days. The preparation that makes it go smoothly takes longer, and starts earlier than most founders expect.
Lawants handles the full company registration sequence for foreign entrepreneurs in Spain, from name reservation through notarial deed, Registro Mercantil filing, tax registration, and initial compliance setup. One point of contact from day one.
FAQ: Company Registration in Spain
The questions below address what foreign entrepreneurs most often need to know before starting the company registration process in Spain.
How do I search for a company registration in Spain?
Search the official Registro Mercantil portal at sede.registradores.org. A company excerpt (nota simple) can be requested by company name or NIF for a small fee, and includes company details, directors, share capital, and annual accounts. The BORME (boe.es/diario_borme) provides historical registry publications for free. Shareholder identities are not publicly disclosed for S.L. companies.
How much does it cost to register a company in Spain?
The official registration costs are: €3,000 minimum share capital for an S.L. (which becomes a company asset, not a fee), notary fees of approximately €150 to €800 depending on share capital and deed complexity, and Mercantile Registry fees of approximately €100 to €400. The AJD tax is exempt for S.L. and S.A. companies since 2010. For qualifying startups using standard bylaws via CIRCE, notary and registry fees are also waived. Professional fees for legal and accounting assistance are separate and vary.
How long does company registration in Spain take?
The Registro Mercantil processes registrations within 7 to 15 working days of receiving the notarised deed. The total timeline from start to finish depends on the preparatory steps: name reservation (2 to 5 days), NIE and NIF applications (2 to 4 weeks for foreign corporate shareholders), and bank account opening (1 to 4 weeks for non-resident entities). When these steps are started in parallel from day one, the total registration process typically completes in 3 to 5 weeks. When started sequentially, it can take 2 to 3 months.
Is there a Companies House equivalent in Spain?
Yes. The Registro Mercantil is Spain’s equivalent of Companies House in the UK or the Handelsregister in Germany. It consists of the Registro Mercantil Central (which handles name reservations and central records) and 52 provincial registries where company deeds are filed and maintained. Unlike some other European registries, the Spanish Registro Mercantil moved its detailed company data behind a paywall in 2011, so free access is limited to basic company existence confirmation.
Can I register a company in Spain without being present?
Yes. Company registration in Spain can be completed remotely via a power of attorney executed before a notary in your country of residence, apostilled, and accompanied by a sworn Spanish translation. The Spanish notary then acts on your behalf for the incorporation deed, and all subsequent registry and tax registrations can be handled by your representative. Some banks require an in-person visit for account opening; this can sometimes be arranged through alternative banking solutions or prior coordination.
Can a foreign company be the sole shareholder of a Spanish company?
Yes. A Spanish S.L. can have a single shareholder, which can be a foreign company, creating what is called an S.L.U. (Sociedad Limitada Unipersonal). The foreign company must obtain its own Spanish NIF before the incorporation deed is signed, using Form EX-15 submitted to the Agencia Tributaria. This process takes 2 to 4 weeks and is the most common source of delay in foreign-owned company registrations in Spain.
