Partner-Led New Boutique: Del Olmo Legal Launches in Buenos Aires, offering Elite M&A, Real Estate, and Complex Dispute Resolution

Mariano del Olmo and Marcelo Antonio Pepe have launched Del Olmo Legal, a new partner-led legal boutique in Buenos Aires.

The firm is built on the core principles of partner-level attention and uncompromising technical rigor. del Olmo Legal focuses on Mergers & Acquisitions (M&A), corporate law, real estate, and complex disputes, combining the discipline and technical depth expected of a large firm with the agility, responsiveness, and proximity of a specialized boutique.

The firm’s lawyers advise clients in both Spanish and English on both Argentina-focused and sophisticated cross-border matters, ensuring seamless communication and execution for international clients.

A New Model: Hands-on, Agile, and Accountable

"We built a structure that reflects how I actually like to work — hands-on, agile and accountable," says Mariano del Olmo, Founding Partner. "Our goal is to add real value to our clients’ business decisions, turning complex legal questions into clear, executable strategies that generate tangible value. Technical depth matters, but so do practicality and integrity."

This philosophy underpins the firm’s approach, ensuring that legal advice is an integral part of the client’s strategic planning. "Clients expect clarity and pace," adds Partner Marcelo Antonio Pepe. "Our role is to bring both — precise answers and steady guidance."

"We envision del Olmo as a serious boutique –new, yet experienced; and above all, guided by integrity," states Mariano del Olmo, emphasizing the firm’s commitment to excellence and ethics.
