Buying or Taking Over an Existing Business in Spain

Buying an operating business can be a faster route into the Spanish market than setting up a new company, but it requires careful legal review. On this page we explain the due diligence checklist, the differences between purchase contract types, and the administrative steps required.

Why Is Due Diligence Essential?

Before buying any operating business in Spain, a complete legal and financial due diligence review is essential. This review reveals hidden risks such as outstanding tax debts, ongoing employment claims, invalid contracts with suppliers, or expired business licences, before the final contract is signed.

Due Diligence Checklist

  • Reviewing the company's outstanding tax and social security debts
  • Reviewing active contracts (suppliers, key clients, employees)
  • The status of operating licences and business permits
  • Any history of ongoing or potential legal or employment claims
  • The status of the business premises' lease and its transfer terms

Share Deal Versus Asset Deal

Contract typeKey feature
Share DealThe buyer acquires full ownership of the company, including all its past debts and obligations
Asset DealOnly specified assets (equipment, brand, inventory) are transferred; previous debts generally remain with the seller
Which Option Is Better?

An asset deal generally carries less risk for the buyer, as it does not inherit unknown past debts, but it may be more complex from a tax or administrative standpoint. The right choice depends on each business's specific situation and should be reviewed with legal and tax advice.

Transferring the Business Premises' Lease

If the business operates from a leased property, the lease transfer must be carried out under Spain's Urban Leases Law (Ley de Arrendamientos Urbanos, LAU). Depending on the terms of the original contract, the explicit consent of the property owner or simply formal notification may be required. Carefully reviewing the lease contract's clauses before finalising the purchase is essential.

Notifying Government Offices

Once the purchase is finalised, the change of ownership must be formally reported to the tax office (Agencia Tributaria) and social security (Seguridad Social). This step is essential to update the company's tax status and ensure employees' insurance continues correctly.

Employment Liability in a Business Transfer

Under Spanish labour law, in many cases the buyer is required to maintain the existing employment contracts of the acquired business's employees. Disregarding this obligation can lead to costly employment claims.
