About Us

Firm Overview

Castañer & Cía P.S.C. can provide (bilingual – Spanish & English) legal advice and representation tailored to clients engaged in the maritime, air and land transportation of goods.  We represent a broad range of clients in marine insurance claim cases; Seaman's injury and death cases; cargo carriage and storage disputes; vessel arrest and attachments; oil spills; water pollution claims; vessel repair, financing, operation, construction and re-building disputes; maritime liens; commercial/contractual claims (including charter parties); and a variety of other maritime disputes.

Our primary goal is to avoid litigation through regular review of claims, accurate accident reporting, investigation and notification procedures and, where possible, mediation. In cases where litigation is unavoidable, our attorneys represent clients' interests before regulatory, administrative and arbitral tribunals as well as state and federal courts.

The Island of Puerto Rico has a great deal of nautical activity.  The construction of the Port of the Americas in Ponce, the renovation and improvement of existing ports, and the increasing pleasure boat activity in the Island, have created a higher demand for specialized maritime legal services.
