A maritime attorney has legal responsibilities to uphold and protect maritime law, which is the set of rules designed for any activity that happens on bodies of water. Your duties as a maritime attorney include representing vessel owners, people on cruise lines, casual boaters, and other people in legal cases for events that happened at sea. Like all attorneys, you are responsible for planning a course for litigation and filing claims on behalf of a client. A maritime attorney can work on cases that involve injuries, financial disputes, mental health suffering, illness, workers’ compensation, or death.
