Salvage and treasure also fall under maritime law, however there are many areas of contention in the law as it applies to treasure and salvage based on the type of salvage or treasure as well the merit of the claim through federal court. Typical the salvager is eligible to up to 50% of the value of the salvage if the owner is able to put in a claim.

Treasure, where the original owner is usually no longer living or cannot be traced, the estate or descendants may still have a claim to the treasure, although the finder will often have a greater claim on the full amount of the treasure. Historical treasures may also be included in this category.

There are several international universities around the world that offer specific courses of study in international maritime law. In the United States the Tulane Law School in New Orleans is the only school offering an LLM in Admiralty.
