Mergers & Acquisitions in Spain: Legal Process and Due Diligence

Spain is a vibrant M&A market, attracting both EU and international buyers. But navigating a merger or acquisition in Spain requires careful legal planning, financial vetting, and regulatory compliance.

This guide walks you through the M&A process in Spain, including legal structures, due diligence, contract negotiations, and regulatory approvals.


🏛️ Common M&A Structures in Spain

When acquiring a business or merging with a Spanish entity, typical deal structures include:

Structure Description
Share Purchase (SPA) Buyer acquires shares in a Spanish company
Asset Purchase Buyer acquires specific assets and liabilities
Merger (Fusión) Two entities combine into one legal entity
Spin-off/Division (Escisión) Business is split into multiple parts or spun off

Each structure has tax, legal, and operational implications. Share purchases are most common in Spain.


🧠 Legal Due Diligence

Before closing any deal, a buyer must conduct a thorough due diligence review, typically covering:

  • Company structure and corporate records

  • Employment contracts and labor risks

  • Tax compliance and liabilities (Modelo 200, IVA, IRPF, etc.)

  • Intellectual property and trademarks

  • Commercial leases and real estate

  • Regulatory licenses and permits

  • Litigation, disputes, or liabilities

💡 Access to the company’s “Libro de Actas” and financial statements from the Mercantile Registry is key.


📜 Drafting the Purchase Agreement

The main legal document is typically the Share Purchase Agreement (SPA) or Asset Purchase Agreement (APA).

It should include:

  • Price and payment terms

  • Representations and warranties

  • Indemnification clauses

  • Post-closing obligations

  • Confidentiality & non-compete clauses

  • Closing conditions

📌 Spanish law requires many M&A documents to be notarized and filed with the Registro Mercantil.


⚖️ Regulatory Approvals

Some M&A deals in Spain require prior regulatory approval:

Authority When Required
CNMC (Competition Authority) If merger may affect market competition
CNMV If publicly listed companies involved
Sector-specific regulators e.g. banking, telecom, energy

Foreign investments may also need prior notification or screening under Spain’s FDI regime (for defense, tech, critical infrastructure sectors).


💶 Tax Considerations in Spanish M&A

Tax planning is essential. Key factors include:

  • Capital gains tax on sale of shares

  • Transfer taxes on asset purchases (usually 6–10%)

  • VAT exemptions for certain business transfers

  • Loss of tax credits or carryforwards in reorganizations

  • Possible use of tax-neutral mergers under Spanish law

It’s critical to conduct tax due diligence and possibly structure the deal through a holding company.


🤝 Post-Merger Integration Issues

After a merger or acquisition, plan for:

  • Employment transitions and harmonization

  • Renegotiation of supplier or lease agreements

  • Trademark or brand transitions

  • Tax and accounting consolidation

  • Notifying the Registro Mercantil and tax authorities


🌍 Cross-Border M&A in Spain

Spain welcomes cross-border deals. For foreign buyers:

  • EU companies enjoy free access under single market rules

  • Non-EU buyers may need FDI screening clearance

  • Bilingual documents and international notarial certifications may be required

  • Local representation via Spanish legal counsel and notary is essential
