Legal Due Diligence for M&A Transactions in Spain

Comprehensive pre-acquisition review of the target company. 6 dimensions, three report formats tailored to each stage of the deal, and SPA clause structuring designed to protect the investor after closing.

Scope of review

The 6 dimensions of due diligence in Spain

Effective due diligence is not a checklist — it is a risk analysis oriented towards decision-making and price structuring. We cover the six dimensions that determine the real value of the company and the investor's actual exposure.

01

Legal & Corporate

  • Articles of association and shareholders register
  • Shareholders agreements and para-social agreements
  • Companies Register status and BORME publications
  • Pending litigation and contingent liabilities
  • Powers of attorney and authorised signatories
  • Material contracts and change-of-control clauses
Key risk: Hidden liabilities, change-of-control clauses, restrictions on share transfer.
02

Regulatory

  • Sector licences and administrative authorisations in force
  • Ongoing enforcement and disciplinary proceedings
  • Public contracts (LCSP) and subrogation obligations
  • Operator registrations and special qualifications
  • CNMC, AEMPS, MITECO and DGT compliance by sector
  • History of administrative inspections
Key risk: Non-transferable licences, sanctions not yet final, public contracts with assignment restrictions.

04

Labour

  • Headcount, senior management structure and retention agreements
  • Applicable collective bargaining agreement and ultra-activity
  • Active ERTEs (furlough) and ongoing EREs (redundancies)

Tax

  • Corporate Income Tax: tax audit minutes and ongoing reviews
  • VAT: net liability position and pending refunds
  • Transfer pricing and related-party transactions
  • Outstanding tax debts and deferred payment arrangements
  • Unconsolidated tax benefits (R&D, ZEC, etc.)

Key risk: Undisclosed encumbrances, leases with purchase options or right of first refusal, land in irregular urban planning status.

Engagement formats

Three formats tailored to each stage of the transaction

The right format depends on the stage of the deal, the time available and the size of the transaction. All three are complementary and can be combined in phased processes.

Red Flag DD

TIMELINE1-2 weeks
SCOPECritical risks only
DELIVERABLEExecutive report covering deal-breakers and material price-affecting findings
When to use: Pre-LOI decision. Competitive bidding with limited time. First phase in staged processes.
MOST COMMON

Full Memorandum

TIMELINE3-8 weeks
SCOPEExhaustive review of all 6 dimensions
DELIVERABLEFull report with risks classified A/B/C and SPA structuring recommendations
When to use: Material-value transactions. Baseline for negotiating R&Ws, indemnities and price adjustments in the SPA.

Vendor DD

TIMELINE4-8 weeks
SCOPEAgreed scope with the seller
DELIVERABLEReport commissioned by the seller to accompany the data room and made available to all bidders
When to use: Competitive sale processes. Enables faster closing and reduces information asymmetry. Compatible with RWI Insurance.

Post-DD structuring

SPA clauses that protect the investor after closing

Due diligence does not end with the report. Its findings feed into the Share Purchase Agreement (SPA) through five protection mechanisms that cap buyer exposure and distribute identified risks between the parties.

R&Ws

Representations & Warranties

Statements and guarantees made by the seller about the condition of the company at closing: accuracy of financial statements, asset ownership, absence of undisclosed litigation and regulatory compliance. If they prove false or incomplete, they trigger seller liability during the survival period — typically 18-24 months for general R&Ws and up to the applicable statute of limitations for tax and environmental warranties.

Indemnities

Specific Indemnities

Specific reimbursement obligations negotiated for known liabilities identified in the due diligence: ongoing tax contingencies, environmental sanctions not yet final, labour proceedings at an advanced stage. Unlike R&Ws, indemnities do not require proving a warranty breach — the mere occurrence of the liability triggers the payment obligation.

Earn-out

Deferred Conditional Price

A component of the purchase price that is deferred and contingent on the achievement of post-closing business targets (EBITDA, revenue, contracts won). Reduces buyer risk in transactions with high uncertainty about future performance. Requires precise definition of calculation mechanisms, measurement periods and buyer monitoring rights to avoid post-closing disputes.

Escrow

Escrow Retention

A portion of the price (typically 10-20%) held in a deposit account for a defined period (12-24 months) as security for R&Ws and indemnity claims. Released to the buyer if justified claims arise; to the seller if the period expires without claims. Replaces direct price retention by the buyer and provides a clean closing for both parties.

RWI Insurance

Representations & Warranties Insurance

An insurance policy that transfers the risk of warranty breach to an insurer. Particularly recommended for: transactions above €20 million, competitive processes where the seller requires full liquidity at closing, private equity funds needing a clean exit, and deals with material environmental or regulatory uncertainty. Typical premium: 1-3% of the insured amount. Compatible with Vendor DD.

Royal Decree 571/2023 · Foreign investment control

FDI Screening: the step that cannot be skipped

For non-EU investors, FDI Screening adds a mandatory layer that must be resolved before closing. The due diligence identifies whether the target falls within the control perimeter and how much time should be reserved for the authorisation process.

Three cumulative conditions (RD 571/2023)

  1. The investor does not reside in the European Union
  2. The acquisition exceeds 10% of the share capital of the Spanish company
  3. The company operates in a strategic sector: energy, defence, critical infrastructure, sensitive data, biotechnology, media or artificial intelligence

If all three conditions are met:

The transaction cannot close without prior authorisation from the Spanish Council of Ministers. Proceeding without authorisation renders the transaction null and void and may trigger administrative sanctions. Typical processing time: 3 to 6 months. This timeline must be factored into the M&A calendar from the outset and reflected as a condition precedent in the SPA.

Preguntas frecuentes

How long does a legal due diligence take in Spain?

The typical timeline ranges from 3 to 8 weeks depending on scope and company size. A Red Flag DD can be completed in 1-2 weeks. A full memorandum requires 3-8 weeks depending on the volume of the data room and regulatory complexity. Environmental and regulatory reviews are typically the most time-consuming in Spain due to the volume of regional authorisations and the fragmentation of applicable rules.

What is the difference between a Red Flag DD and a full memorandum?

A Red Flag DD identifies only the critical risks that could block the transaction or require significant price renegotiation. It is faster (1-2 weeks) and suited for pre-LOI decisions or competitive processes. The full memorandum provides an exhaustive analysis of all 6 dimensions, classifies all risks and delivers detailed recommendations for SPA structuring. It is the baseline document for negotiating R&Ws and specific indemnities.

What are R&Ws in a share purchase agreement?

Representations and Warranties are the statements and guarantees made by the seller about the condition of the company at closing: accuracy of financial statements, asset ownership, absence of undisclosed litigation, regulatory compliance and contract validity. If they prove false or incomplete, they trigger seller liability during the survival period — typically 18-24 months for general R&Ws and up to the applicable statute of limitations for tax and environmental warranties.

When is FDI Screening mandatory for an acquisition in Spain?

Under Royal Decree 571/2023, prior authorisation from the Spanish Council of Ministers is mandatory when three conditions are met simultaneously: the investor does not reside in the EU; the acquisition exceeds 10% of the share capital; and the target operates in a strategic sector (energy, defence, critical infrastructure, sensitive data, biotechnology, media or artificial intelligence). The authorisation must be obtained before closing. Operating without it renders the transaction null and void.

When is RWI Insurance recommended?

RWI Insurance is particularly recommended for: transactions above €20 million, competitive processes where the seller requires full liquidity at closing, private equity funds that need a clean exit, and deals with material environmental or regulatory uncertainty. Typical premium: 1-3% of the insured amount. Compatible with Vendor DD and facilitates faster closings.
