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.

Clients expect the best from us. We have built a reputation of providing the highest quality of legal advice as well as the highest level of personalized service. In addition, our reputation for transparency and business integrity through the law sets us apart and continues to attract top talent to the firm.

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.

In addition to being a multidisciplinary team, the work 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.

In Guatemala, notably, the office’s managing partner and firm co-managing partner Juan Carlos Castillo, served as president of the board of the largest exchange in Guatemala for eight years, giving the team standout strength in securities mandates. We also have the leading practice in the energy sector – particularly electricity related matters – owing to extensive industry experience and a profound market knowledge.

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 as well as entering the Paraguay market in June 2020.

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 culture is trust, mutual respect and integrity through the law.
