Luis Guillermo Fonseca Herrera
Criminal defense lawyer and private investigator in Costa Rica
If you're facing a criminal investigation in Costa Rica, or you need reliable information for a legal matter, I can help you understand where you stand and what to do next.
How I can help
Foreign residents, visitors and companies abroad often don't know how the Costa Rican criminal system works. I can explain it and handle the matter locally. The detailed service pages are in Spanish.
Criminal defense
I represent and advise people in a criminal case in Costa Rica, from the first steps to trial.
Private investigation
I gather and verify information lawfully for a legal matter or a specific question.
Forensic technical consulting
I review how technical evidence was collected, kept and what it actually shows.
Experience from inside the system
I spent more than twenty years at the OIJ, Costa Rica's Judicial Investigation Agency, and I know how an investigation is built, step by step.

I was Regional Director in Liberia, served as a criminal judge, and led or supervised more than 1,000 investigations. I work as a criminal lawyer and as a private investigator authorised under Costa Rica's private security services law, as part of Lex Forum Abogados. I can't promise any particular outcome, because that depends on the facts and the evidence in each case.
