Work areas

This firm is elite for services in the following work areas.

BLP’s speciality in El Salvador is corporate and M&A law, but the firm’s prowess does not stop there, with the banking and finance team experiencing growth in recent years. The fact that the office is now led by banking virtuoso Zygmunt Brett can only help to increase the profile of the regional heavyweight’s local firm.

Lawyers here are likewise adept at providing labour and tax advice. BLP is looking to further broaden its offering, with plans to expand the litigation and IP practice groups.

The firm prioritises client satisfaction and constantly invests in technological developments to improve services. It now has new accounting and billing software, and has rolled out an artificial intelligence platform in collaboration with Microsoft for the automation of notary public services, including immigration documentation. BLP is also in the process of developing software aimed at providing client quotes based on a calculation of hours of work required by a project, and a front-end software for client use to ensure that any regulatory and government documentation will be visible in the app, thereby providing up-to-date regulations in real-time. 

The prioritisation of technological developments forms part of a broader strategy of providing added-value services for clients, while facilitating talent retention at the firm. Meanwhile, the firm has an established programme – BLP University – aimed at its lawyers and focused on technical skills, as well as more soft skills training in the future.

The firm’s client-centric philosophy is demonstrated by its popularity among many large businesses in Latin America. According to a study, “Who Represents Latin America’s Biggest Companies”, published by the Latin American Corporate Counsel Association, which is affiliated to Latin Lawyer, as a regional law firm BLP represents 16 of the 100 biggest companies in Latin America, making it the most popular firm among these clients in Central America.

BLP is aware of the need to place resources into diversity efforts and corporate social responsibility. Achieving a greater degree of gender parity is important to the firm and it is taking part in equality and inclusion initiatives, such as the International Women in Law programme, and it is establishing a mentoring scheme for young girls. Pro bono work is also of great significance to BLP, most recently focusing on matters including freedom of the press and media rights in the wake of government restrictions.

With offices in five Central American countries, the Salvadorean office can depend on its regional presence as a source for work. The firm has been nominated a 2023 Latin Lawyer Elite firm in Central America thanks to its rounded approach to management, which emphasises technology, innovation and flexibility, as well as its strong position in transactional work. A horizontal structure, combined with an inclusive and enjoyable working environment for lawyers, has enabled the firm to expand rapidly across the region and become a market leader.

While BLP’s primary objective for the years to come varies slightly across the region with individual strategic plans for each office, the underlying themes remain consolidation and stable growth.


Costa Rican partner Luis Castro is the firm’s regional managing partner and sits on the regional executive committee alongside David Gutiérrez and Eduardo Calderón. Zygmunt Brett is the local managing partner in El Salvador. The firm has a wider regional managing committee formed of the executive committee members along with Zygmunt Brett, Luis Ruiz, José Álvarez, Ernesto Rizo and Karla Aguilar.


BLP operates from the country’s capital San Salvador. The firm has offices in Guatemala, the Honduran cities of Tegucigalpa and San Pedro Sula, and Nicaragua’s capital Managua. Its largest office is in San José, Costa Rica, where it also maintains outposts in Los Sueños and Guanacaste. A representative office in Madrid was added in 2017.
