How Shipwreck Salvage Law Works—and Who Owns the Treasure

Two Doctrines, One Ocean Floor

When a ship sinks, the question of who may recover it—and who gets to keep what's found—falls under admiralty law, one of the oldest branches of the legal system. Two competing doctrines govern the process: the law of salvage and the law of finds. Understanding the difference is essential to grasping how courts handle everything from Spanish galleons laden with gold to a Titanic survivor's life jacket.

The law of salvage applies when an owner still has a legal claim to the vessel. Under this doctrine, anyone who voluntarily helps recover a ship or its cargo from peril at sea is entitled to a reward—but not ownership. The size of the reward depends on factors such as the value of the property saved, the degree of danger involved, and the skill the operation required. Crucially, the original owner retains title to the wreck.

The law of finds, by contrast, applies when a vessel has been truly abandoned. Here, the first person to take possession of the wreck can claim ownership outright—a principle closer to "finders keepers." However, courts set a high bar for proving abandonment. Mere passage of time does not extinguish ownership; there must be evidence of an express intent to relinquish the property.

How a Salvage Claim Works in Practice

A salvor who locates a wreck typically files a claim in an admiralty court, which has jurisdiction over maritime disputes. The court may grant the salvor "salvor-in-possession" status, giving them exclusive rights to conduct recovery operations—while preventing rivals from interfering.

This status does not equal ownership. In the most famous example, RMS Titanic, Inc. was awarded exclusive salvage rights to the Titanic wreck by a U.S. federal court in Virginia in 1994. The company recovered more than 5,500 artifacts across multiple expeditions. Yet the court explicitly prohibited the company from selling or dispersing the artifacts individually, requiring them to be preserved as a single collection for research and public display.

Salvage rewards are determined after the fact by the court, which weighs a set of factors codified over centuries. These include the labor and expense of the salvors, the promptness of service, the danger to the salvors' own equipment, and the value of the property at risk. Awards can range from a modest percentage of a cargo's value to the full appraised worth of the recovered items.

International Protections and the UNESCO Convention

As diving technology advanced in the late twentieth century, governments grew alarmed at the looting of historically significant wrecks. In 2001, UNESCO adopted the Convention on the Protection of the Underwater Cultural Heritage, which covers all traces of human existence that have been submerged for more than 100 years.

The convention establishes several key principles. In situ preservation—leaving artifacts on the seabed—is considered the preferred first option. Recovery may be authorized only when it makes a significant contribution to knowledge or protection of the heritage. Most importantly, the convention declares that underwater cultural heritage shall not be commercially exploited for trade or speculation.

As of the mid-2020s, more than 70 nations have ratified the convention. Notably, the United States and United Kingdom have not, though both have enacted domestic legislation. The U.S. passed the R.M.S. Titanic Maritime Memorial Act and later incorporated Titanic protections into the 2017 Consolidated Appropriations Act, making it illegal for any U.S. entity to disturb the wreck without federal permission.

Why Personal Artifacts Are Treated Differently

Not all Titanic-related items come from the wreck site. Personal possessions carried off the ship by survivors—clothing, documents, life jackets—belong to those individuals and their descendants under ordinary property law, not admiralty law. These items can be freely bought and sold.

This distinction explains why a life jacket worn by first-class passenger Laura Mabel Francatelli could be auctioned by Henry Aldridge & Son for over $900,000, while the thousands of artifacts recovered from the ocean floor remain locked under court-supervised stewardship. The legal line is clear: what a survivor carried ashore belongs to the survivor; what stayed with the ship belongs to history.

A Framework Under Pressure

Maritime salvage law continues to evolve as new technologies—remotely operated vehicles, advanced sonar, and deep-sea robotics—make ever-deeper wrecks accessible. Courts and international bodies face growing tension between rewarding the costly, dangerous work of salvors and protecting underwater heritage from commercial exploitation. The result is a patchwork of national laws, international conventions, and case-by-case judicial decisions that together determine who may touch a shipwreck and what happens to what they find.
