Aguilar Castillo Love
Costa Rica

Corporate and M&A Tier 1

Corporate powerhouse Aguilar Castillo Love is well equipped to undertake M&A, joint ventures and any other type of business combination, as well as restructurings. The team's impressive skill set further includes advising on foreign investment, start-ups and greenfield projects, as well as assistance with commercial matters such as distribution, franchising and outsourcing. The 'agile' and 'exceptional' practice headed by John Aguilar-Quesada, John Aguilar-Osborne and Marco Solano provides an international outlook and is capable of handling multi-jurisdictional matters. Senior partner Aguilar-Quesada brings decades of experience in all kinds of corporate issues to the table, as does founding partner Aguilar-Osborne. Solano is particularly active in cross-border transactions and Esteban Agüero Guier has merger control expertise. Antitrust and competition law is also a key aspect of Andrea Sáenz' practice.


‘This practice really exemplifies agile, personalised service. Esteban Agüero is truly focused on the client and it is good to know you can contact a partner at the firm quickly and directly without having to go through different levels as at other firms, where it is very difficult to get to talk to a partner.’

‘Their client service is exceptional: they provide quick and concise responses which reflect their broad knowledge.’

‘Their availability to clients (and easy access to partners) and the speed of their responses sets them apart.’

‘The firm has a strong track record in Central America, which makes handling legal matters in the region a lot easier.’

‘Aguilar Castillo Love’s comprehensive support in the region is crucial to the smooth operation of our business.’

‘Esteban Agüero is very responsive to all of our requirements and seeks to provide answers as quickly as possible. Furthermore, he provides timely follow-up on critical issues that we have to deal with in Costa Rica, as well as in Guatemala.’

Compliance Tier 2

Internal assessments, training and support with local implementation of compliance systems and anti-corruption programmes are the pillars of Aguilar Castillo Love's compliance practice. Corporate and commercial partner Tatiana Rojas Hernández is recommended for related work.

Dispute resolution Tier 2

At the 'results-driven' Aguilar Castillo Love, the primary focus is on contentious matters related to M&A and compliance, as well as environmental, antitrust and corporate law. Specific areas of expertise include international trade issues, anti-dumping cases and acting for healthcare clients. The department is spearheaded by a trio comprising John Aguilar-Osborne, Esteban Agüero Guier and John Aguilar-Quesada. Aguilar-Quesada shines particularly in cases related to M&A, whereas Agüero often handles arbitration cases and founding partner Aguilar-Osborne brings a wealth of experience in various practice areas to the table. Criminal litigator Rodolfo Brenes Vargas handles anti-corruption investigations and associate Laura Rodríguez Amador is adept at assisting with administrative, civil, constitutional and criminal cases.


‘ACL is a results-driven firm. They understand the needs of the client. Because they have offices throughout Central America, they can give clients a regional perspective. The firm is creative with billing and places the interests of the client above firm profits.’

‘Esteban Agüero Guier is an astute litigator. He communicates frequently and takes a common-sense approach to litigation. Esteban responds within 24 hours regardless of what he is doing. He does not tell the client what he believes the client wants to hear.’
