## What Is Maritime Law?

Maritime law, or admiralty law, includes rules and treaties for private maritime business and issues like shipping or offenses on open water. Maritime law governs maritime business, nautical matters, and provides a legal framework for disputes. Maritime law is critical for global commerce and the protection of resources and personnel at sea.

Maritime law is independent as a jurisdiction from national laws. The International Maritime Organization enforces enforcing regulations. In contrast, international rules governing the use of the oceans and seas are known as the Law of the Sea.

### Key Takeaways

*   Maritime law governs private maritime questions, disputes, offenses, and other nautical matters separately from national laws.
*   The International Maritime Organization (IMO) keeps international maritime conventions up to date and develops new agreements as needed.
*   Maritime law covers insurance claims, civil matters between shipowners, seamen, passengers, and piracy.
*   Key IMO conventions focus on safety, pollution prevention, and seafarer training standards.
*   The U.S. Constitution grants federal district courts exclusive jurisdiction over admiralty law cases, creating a uniform body of law.

## Key Elements of Maritime Law

In many developed countries, maritime law operates independently and follows its own set of codes, separate from national laws. The [United Nations (UN)](https://www.investopedia.com/terms/u/united-nations-un.asp), through the [International Maritime Organization (IMO)](https://www.investopedia.com/terms/i/international-maritime-organization.asp), has issued numerous conventions that can be enforced by the navies and coast guards of countries that have signed the treaty outlining these rules.

Maritime law governs many of the [insurance claims](https://www.investopedia.com/terms/i/insurance_claim.asp) relating to ships and cargo; civil matters between shipowners, seamen, and passengers; and piracy. Additionally, maritime law regulates registration, license, and inspection procedures for ships and shipping contracts; maritime insurance; and the carriage of goods and passengers.

Established in 1948 and operational since 1958, the IMO ensures maritime conventions are current and develops new ones as needed.

Today, many conventions regulate various aspects of maritime commerce and transport. The IMO names three conventions as its core:

*   The International Convention for the Safety of Life at Sea
*   The International Convention for the Prevention of Pollution from Ships
*   The International Convention on Standards of Training, Certification and Watchkeeping for Seafarers

> On its website, the IMO has lists of conventions and amendments expected to enter into force in the current and coming years.

By 2024, governments of 176 IMO member states will implement IMO conventions for ships registered in their countries. Local governments enforce IMO convention rules for their ships and decide penalties for violations. Some ships must carry certificates proving they meet inspection standards.

## The Evolution of Maritime Law Through History

The origins of maritime law can be traced all the way back to ancient Egypt. In ancient times, ships transported goods, and clear rules were necessary for safety, fair trade, and dispute resolution.

Written records of formal maritime codes appeared later. Formed around 900 BCE, the Rhodian Sea Laws established rules for the Mediterranean Sea. These laws governed seafaring trade in the area, influenced the Romans, and remained in effect through the 12th century.  

> **Fast Fact**
>
> The oldest maritime laws on record were reportedly created on the island of Rhodes, Greece.

European maritime laws gradually evolved over the following centuries. Key developments that helped to shape current laws included the Consulate of the Sea, the Rolls of Oléron, and the early English Admiralty laws, which would later help to shape the laws of the sea in the U.S.

Maritime law arrived in the Americas in the 1600s. In 1789, the year that the U.S. Constitution was adopted, federal district courts were given exclusive jurisdiction over admiralty law cases and a uniform body of law was created.

## Maritime Law and Ship Registration

The country of registration determines a ship's nationality. For most ships, the national registry is the country where the owners live and operate their business.

Shipowners often register ships in countries that allow foreign registration. Called "flags of convenience," the foreign registration is useful for tax planning and to take advantage of lenient local laws. Two examples of "flags of convenience" countries are Panama and Bermuda.

## What Is Maritime Law and Why Is it Important?

Maritime law is the body of rules that governs everything that goes on in the sea and open waters. These rules help clear up various disputes that can occur and ensure that the people and organizations that work on the water behave correctly and are protected.

## Who Controls Maritime Law?

International maritime law is governed by the International Maritime Organization (IMO). A specialized agency of the United Nations, it is the IMO’s job to establish the framework and regulations for the safety, security, and environmental performance of shipping on an international, universal level.

## What Is the Difference Between Maritime Law and Law of the Sea?

Maritime law generally applies to private shipping issues, whereas the law of the sea is largely recognized as referring to public international law. In other words, the latter governs how nations should behave in maritime environments.

## The Bottom Line

Maritime law is vital in regulating activities on the seas, ensuring safety, fair trade, and the protection of those who work on and utilize maritime resources. International organizations, particularly the International Maritime Organization (IMO), maintain and update the international maritime conventions and standards. 

There is a rich history and evolution of maritime law from ancient times to modern days, having a long-standing significance and adaptation over centuries. Maritime law is not the same as the Law of the Sea, which is the international rules governing the use of the oceans and seas, but not the activities.

The IMO includes existing conventions that dictate modern maritime standards, such as the International Convention for the Safety of Life at Sea. Maritime law has in preventing anarchy in nautical environments, playing a fundamental role in the stability of global commerce.
