Buying an Existing Business in Spain: The Legal Due Diligence Guide

Why buy an existing Spanish company instead of starting from zero

Spain has roughly 1.1 million family-controlled companies, a large share built by founders now in their sixties and seventies with no obvious successor lined up. That generational gap is quietly producing a wave of businesses for sale across retail, hospitality, tourism, and local services, exactly the sectors a foreign investor relocating to somewhere like the Costa del Sol is often already looking at. Buying one of these businesses, rather than founding a new one, means acquiring existing revenue, an existing customer base, existing licences, and staff who already know how the business runs, instead of betting everything on a business plan that has never been tested against real customers.

That advantage comes with a mirror-image risk: you are also acquiring whatever problems the business already has, some visible, some not yet. The entire purpose of due diligence, and the reason the deal structure matters as much as the price, is to find out which is which before you sign, and to price or structure the deal around what you find rather than discovering it afterwards.

On the Costa del Sol specifically, the businesses most often changing hands are hospitality, retail, and tourism-facing operations, restaurants and bars with an established clientele, small hotels and aparthotels, retail units in tourist-heavy streets, and short-let apartment portfolios already holding a tourist licence. A licence already in force, rather than one you would have to apply for from scratch, is frequently the single most valuable thing a target business owns, since Andalucia’s tourist licence rules and municipal moratoriums in some areas have made new licences considerably harder to obtain than they were a decade ago. Confirming that a licence genuinely transfers with the business, and is not tied personally to the outgoing owner, is one of the first things we check, alongside our dedicated Tourist Licence guide for the underlying rules.

Share deal vs asset deal: which structure protects you

Every acquisition in Spain is structured one of two ways, and the choice shapes everything downstream, price, tax, and risk alike.

Share deal

A share deal transfers ownership of the company itself. Its contracts, licences, employees, and legal identity all carry over automatically, which is often exactly what a buyer wants when the licences or long-term contracts are the real value of the business, a tourist licence, a lease with favourable terms, or a supplier relationship built over years. The tradeoff is that the buyer inherits the company as it stands, liabilities included, known debts, pending litigation, tax exposure from open years, and labour obligations, whether or not they were disclosed before closing.

Asset deal

An asset deal lets the buyer select specific assets and contracts rather than acquiring the company wrapper around them, leaving other liabilities behind with the seller’s original legal entity. This limits inherited risk in theory, but it is fiscally and administratively heavier, since some assets attract transfer tax or VAT that a share deal would not, and some licences or contracts, particularly regulated ones, do not automatically transfer and require fresh applications or third-party consent.

The due diligence checklist: financial, legal, labour, licences

Standard due diligence on a Spanish SME acquisition covers five areas, and a shortcut on any one of them is where problems tend to surface after closing, not before.

• Corporate. Incorporation documents, shareholder register, board minutes, and any pending litigation or corporate disputes.
• Tax. Open tax years still subject to inspection, and any historic exposure that transfers automatically with a share purchase, reviewed alongside the buyer’s own accountant.
• Labour. Every inherited employee, their contracts, seniority, and any pending severance exposure, since these follow the business under Spanish law regardless of deal structure.
• Real estate and licences. Title, urban-planning status if property is owned rather than leased, and confirmation of what actually transfers with the business versus what needs re-application.
• Financial. The historic accounts behind the numbers the seller is presenting, distinct from the commercial valuation of the business itself, which remains the buyer’s own accountant’s role, not ours.

A standard SME due diligence review typically runs 6 to 10 weeks from engagement to a clean report, though the notarial closing itself, once terms are agreed and due diligence is complete, can happen within days. Due diligence reduces risk meaningfully, it does not eliminate it; no review can guarantee the absence of every undisclosed liability, which is exactly why the deal structure and the purchase agreement’s warranties matter as a second layer of protection.

One area worth flagging on its own: certain sectors carry a Foreign Direct Investment screening requirement for extra-EU buyers, or in some cases EU buyers, above particular ownership thresholds. Whether your specific acquisition triggers that screening depends on the sector and the structure of the deal, and it is assessed early, as part of the due diligence scope, rather than assumed either way in general content like this.

Employment law traps: the three-year joint labour liability

This is the single most important, and most commonly underestimated, legal fact in a Spanish business acquisition. Under article 44 of the Estatuto de los Trabajadores, a buyer is automatically subrogated into all of the target’s existing labour and Social Security obligations the moment the transfer completes. Employees transfer with their existing contracts, seniority, and conditions intact, you cannot simply keep the business and let the staff go as part of the deal. If changes to employment terms are intended, consultation with employee representatives is required first.

In practice this means the employment review is not a formality bolted onto the end of due diligence, it should shape the negotiation itself: indemnities from the seller, an escrow held back against known risks, or a price adjustment where the labour file shows genuine exposure, are all standard tools we use to convert this statutory liability from an open-ended risk into something priced and managed.

Notary mechanics, NIE, and CIF

Transfers of participaciones in a Spanish SL require a public deed executed before a Spanish notary, this is not optional paperwork, it is how ownership legally changes hands. Company bylaws frequently include statutory pre-emption rights in favour of existing shareholders, which apply unless they are formally waived before the transfer, so checking and clearing these early avoids a closing delay discovered at the worst possible moment.

On the buyer’s side: an individual foreign buyer needs a NIE (Numero de Identificacion de Extranjero) before the deed can be signed, and a foreign company acting as buyer needs a Spanish CIF. Neither is difficult to obtain, but both take lead time, and we sequence this alongside the due diligence timeline specifically so the notary appointment is not the thing holding up an otherwise-ready deal.

Residency via acquisition: the cuenta propia route

Buying an existing company can genuinely support a Spanish residency application, through the cuenta propia self-employment route, not the Entrepreneur Visa. Cuenta propia explicitly covers someone who wants to “crear una nueva empresa, comprar una empresa ya existente o crear una franquicia”, create a new company, buy an existing one, or set up a franchise, and operate it as a self-employed administrator or director. This is a meaningfully different fit from the Entrepreneur Visa, which requires a favourable ENISA innovation report and is the wrong tool for a conventional acquisition, a bar, a retail shop, a hospitality business, since there is no innovation test to fail on the cuenta propia route.

For a larger acquisition, the Highly Qualified Professional route can also apply if the target company meets the size test, or secures the DGCOMINVER “interes general” alternative, letting the acquired company petition for your own director authorization; that mechanic is specialist territory worth a direct review rather than a general assumption. For most SME acquisitions, cuenta propia is the natural fit, requiring a viable business plan validated by a recognized body, resources around the monthly IPREM threshold, and a clean five-year criminal record. Buying an established, already-profitable business is often a stronger file than a paper business plan for a brand-new venture, since the numbers behind the application are real, not projected.

Timeline and what a typical SME acquisition costs

A realistic path runs: 1 to 2 weeks to agree heads of terms and the deal structure, 6 to 10 weeks of due diligence running in parallel with financing and, if relevant, the residency application’s own business plan validation, then a notarial closing that can happen within days once everything is agreed. Government and third-party costs, notary fees, Mercantile Registry fees, and any accountant or valuation specialist the buyer engages separately, sit outside our legal fee and are billed at cost by the relevant provider.

Our own fee for due diligence and acquisition support is quoted per case, after we know the target business, its sector, its employee count, and whether real estate or regulated licences are involved. A small two-employee retail acquisition and a twenty-employee hospitality business with a tourist licence are genuinely different pieces of work, and we would rather quote accurately once we know what we are looking at than publish a flat number that under-serves one of those cases.

Two tax questions tend to surface only after closing, worth raising before you sign rather than after. First, once you eventually sell the business or its underlying assets, ordinary capital gains rules apply to the disposal, and how the acquisition was structured today, share deal or asset deal, affects that calculation later; our Capital Gains Tax guide covers the mechanics. Second, if the acquisition is part of a move to Spanish tax residency rather than a purely passive investment, the shareholding itself becomes part of your worldwide net worth for Spanish wealth tax purposes once you are resident, where Andalucia’s regional bonification is genuinely relevant; see our Wealth Tax in Spain guide for how that interacts with Beckham Law if you also qualify for that regime.
