M&A and corporate law
Buying or selling a business. Restructuring a corporate group. Negotiating a shareholders' agreement that actually works when things get difficult. Each of these decisions defines the future of a business — and each requires counsel that combines technical rigour with real transactional experience.

We have led and advised national and international M&A transactions for over two decades — from industrial company acquisitions to multinational restructurings, private equity, joint ventures and divestments.
Mergers and acquisitions
Preliminary assessment, due diligence coordination (legal, tax, labour), risk identification, negotiation and drafting of the SPA or asset purchase agreement (representations and warranties, indemnities, earn-outs, conditions precedent, non-compete covenants), signing and closing management, and post-closing warranty period monitoring.
Corporate law and shareholders' agreements
Company formation, shareholders' agreements, general meetings and boards of directors, corporate restructurings (mergers, spin-offs, transformations), directors' liability, and general corporate advisory.
Corporate governance and board secretarial services
Board secretarial services that go beyond mere formality: preventive advice to directors, compliance review, meeting preparation with prior analysis, and minutes that reflect not just the resolutions but the decision-making process. Over 25 years advising boards of national and international companies, with dual admission in Madrid and New York.
Corporate dispute resolution
When a transaction stalls or a post-closing dispute arises, we offer dual capability: the transactional lawyer who understands the mechanics of the deal, and the mediator who can facilitate a settlement. For disputes requiring litigation, we have a dedicated dispute resolution practice.
The right-size advantage
At a large firm, the partner who won the pitch appears at the start and at the close; the work is done by third-year associates. At Alta Mediación, the professional who analyses your transaction is the same one who negotiates it, closes it, and answers the phone when a problem arises two years later.
Do you recognise yourself?
If any of these situations describe your current challenge, we can help.
- You are considering acquiring a business or a line of business and need advice from due diligence through to closing.
- You want to sell your company (or your stake) and need to prepare the transaction to maximise value and minimise risk.
- A deal in progress has stalled — valuation disagreement, due diligence findings, warranty disputes — and you need to unblock it.
- A post-closing dispute has arisen (price adjustment, breach of rep and warranty, earn-out dispute) and you want to resolve it without years of arbitration.
- You need a shareholders' agreement that addresses the scenarios no one wants to imagine: deadlock, exit, death, divorce.
- You have a corporate dispute — challenge to shareholders' resolutions, separation rights, shareholder exclusion — and need advice before litigating.
For transactions with an international component, our cross-border advisory practice adds an additional advantage: dual admission in Madrid and New York with direct World Bank Group experience.
Where the transaction leaves a Spanish subsidiary that has to be kept alive, we also handle its company secretarial and corporate housekeeping.
