‘Very reliable and practical local advice. As an in-house counsel having no experience in Costa Rica, we were very happy about the robust, efficient support we received.’

‘Marco Solano was always willing to go beyond the instructions given, providing us with an insight into the local market which we could not foresee without his support.

Central America > Corporate and finance Tier 1

Aguilar Castillo Love has offices throughout Central America, as well as a presence in Ecuador and Paraguay. With major regional and international banks and multinational companies among its clients, the firm is well known for its advice on high-value financial and M&A transactions, including cross-border matters. Among the firm's areas of strength are project finance, bond issuances, acquisitions and corporate governance. In Costa Rica, Marco Solano and senior partner John Aguilar-Quesada lead the banking practice and are key contacts for corporate work, along with Andrea Sáenz, an expert in free trade zone matters. Senior partner Juan Carlos Castillo-Chacón is the name to note for finance and corporate matters in Guatemala, and is particularly renowned for advising major players in the energy sector. In Honduras, Juan José Alcerro Milla and Enrique Rodríguez Burchard lead the corporate and finance practices, where project finance is a notable area of expertise. In Nicaragua, Thelma Carrión-Blandón and Violeta Núñez are the key contacts for corporate and finance matters, respectively, and Carlos Roberto Alfaro leads the firm's corporate and M&A practice in El Salvador.

Aguilar Castillo Love has always been at the forefront of legal change and landmark cases. We have consistently redefined what it means to be a leading law firm and continue to provide the highest level of customer service and quality legal advice to a prestigious client base. Our multidisciplinary approach allows us to provide the top-level advice required on market-leading, cross-border transactions and cases, notably including at the intersection of corporate matters and the connected areas of antitrust and competition, finance – including technicalities of financial regulation, compliance, ABC, investigations and corporate crime, and dispute resolution.

Our regional offering now comprises offices across Costa Rica, Ecuador, El Salvador, Guatemala, Honduras, Nicaragua, Panama and Paraguay. We regularly handle our clients’ most challenging legal issues requiring “one-country” expertise or comprehensive and unified regional, cross-border knowledge.

As a multidisciplinary team, the work types on which we advise is varied – from regulatory matters, to complex transactional, global deals and key negotiations. Our expertise cuts across multiple industries, ranging from infrastructure, energy and natural resources, to financial industries, technology, telecommunications and media among others.

We represent a broad range of clients with a particular focus on multinational companies seeking to do business in one or several of the jurisdictions in which we have a presence. We serve clients in all sectors in mergers, acquisitions, joint ventures, splits, spin-offs or any kind of business combination, arrangement or restructuring. True to our commitment to quality, our corporate practice focuses on complex corporate and commercial matters, providing highly personalized service, including partner involvement.

Our business model has proven itself flexible, allowing us to make a number of important moves over the past year, including strengthening our offering across the region with new partner hires in Costa Rica, Ecuador and El Salvador, as well as entering the Paraguay market in June 2020. In our Costa Rica office, we are proud to house the President and Vice President of the Costa Rica Chapter of the World Compliance Association – Sergio Herra and Tatiana Rojas respectively. Our corporate crime team also includes one of the country’s most highly respected corporate criminal litigators – Rodolfo Brenes Vargas – who has handled some of the country’s most high-profile corporate criminal cases in the past year. Another key development is the strengthening of our technology law practice, with a new partner hire in the Costa Rica office.

This growth during the challenging times brought by the global pandemic reflects the strength in our model and direction as a business. We are no longer a Central American law firm, only, but are the first, home-grown Latin American firm – with offices in Ecuador as well as Paraguay. In addition, we frequently coordinate matters including jurisdictions outside of Central America, including – for example – Mexico and the Caribbean.

Our reputation for transparency and business integrity through the law sets us apart and continues to attract top talent to the firm. Our culture is trust, mutual respect and integrity through the law.
