There is no universal permission to collect shipwreck artifacts. Whether recovery is legal depends on the wreck, its location, ownership, protected status and applicable laws; whether it is physically safe depends on the wreck’s hazards and your training. Until the responsible authority confirms that recovery is allowed, leave the artifact where it is, do not touch it, and document its location without disturbing the site.
First identify the wreck and who has authority over it
A diver’s ability to reach an object does not establish a right to take it. Before planning any recovery, identify the wreck as precisely as you can and establish which country, state or other jurisdiction it is in. Then find out whether it is managed or protected by a government agency, sanctuary, state submerged-land authority, private owner, or another responsible body.
- Record the wreck’s name, if known, and its coordinates or general location.
- Check official charts and the relevant agency or site manager’s rules, including permit requirements.
- Find out whether the wreck is government property, a sunken military craft, a memorial or gravesite, or covered by a court order or other site-specific restriction.
- If ownership, jurisdiction or permission is unclear, ask the responsible authority before touching or moving anything. A general online claim is not a permit for a particular wreck.
The legal framework varies by country. In the United States, relevant rules may include sanctuary regulations, the Sunken Military Craft Act, the Abandoned Shipwreck Act, state submerged-land law, federal ownership, and site-specific permits or court orders. NOAA’s MPA legal resource summarizes several of these authorities, but the facts of an individual wreck determine which ones apply.

Viewing a wreck is different from disturbing it
Permission to dive, visit or photograph a wreck does not necessarily include permission to disturb or recover its artifacts. Rules can differ even between nearby sites, so check the actual site’s designation and conditions rather than assuming one wreck’s rules apply to another.
#1 Best Overall
| Activity | What to check |
|---|---|
| Visit or observe | Whether the site allows diving and whether access, operator or safety rules apply. |
| Photograph or document without contact | Whether non-intrusive documentation is allowed and whether any recording or reporting conditions apply. |
| Touch, shift, open, dig up or remove an object | Whether the act counts as disturbance or recovery, who can authorize it, and whether a written permit and specified methods are required. |
Protected sites
NOAA says disturbing a site or recovering artifacts in a U.S. national marine sanctuary without a permit is illegal. Permits are contemplated only in specific circumstances consistent with federal laws. Check the designation and rules for the particular sanctuary; do not treat that statement as a rule for every wreck in every jurisdiction.
Military craft and abandoned wrecks
Sunken military craft and abandoned shipwrecks can have special legal status. NOAA’s legal resource summarizes the U.S. Sunken Military Craft Act and Abandoned Shipwreck Act. Do not assume that salvage customs, the passage of time, or a “finders keepers” interpretation grants permission to collect.
International heritage principles
UNESCO’s 2001 Convention principles make preservation in place the first option for underwater cultural heritage. Recovery may be authorized for significant protection or knowledge purposes, while commercial exploitation and illicit trafficking are to be prevented. The Convention does not itself settle ownership or delimit maritime zones; its reach depends on States Parties and applicable law, so local jurisdiction still matters.
Site-specific examples are not blanket rules
NOAA says divers may visit and photograph the U.S. wreck of the Robert J. Walker without a permit, but should not move or remove its structure or artifacts without NOAA authorization. That distinction illustrates why viewing permission is not recovery permission; it does not establish the rules for other wrecks.
Titanic has a distinct statutory and international framework. NOAA’s documents describe guidelines for research, exploration and salvage, including keeping artifact collections intact under the described guidance and covenants. Those conditions should not be generalized to other wrecks.
Use this decision sequence if you find an artifact
- Before the dive: identify the wreck and its manager. Review official charts, applicable sanctuary, state and federal rules, permit requirements, and any military-craft or gravesite protections. Ask the responsible authority if the applicable rules or ownership are uncertain.
- At the site: observe and photograph without touching, shifting, opening or removing anything. Stay within your qualifications and follow site-specific instructions.
- Record the find in place: note its position and context without moving it. Leave it where it is and report it to the relevant heritage agency or site manager. The object’s position and relationship to the wreck can be part of its archaeological information.
- Before an authorized recovery: obtain written permission and follow the permit’s requirements for methods, documentation, conservation and reporting. Use qualified archaeological and conservation professionals where required. Authorization to dive or view does not by itself authorize disturbance.
Assess physical danger separately from legal permission
An object can be legally recoverable and still be unsafe to approach. Wreck hazards include overhead entrapment, disorientation, silt-outs that eliminate visibility, fishing gear, sharp or unstable structure, pollutants and possible unexploded ordnance. An artifact may be attached to unstable material, buried in silt or located inside a space without a direct ascent. Do not handle an unknown object to test what it is or whether it will move.
- Do not enter a wreck or other overhead space unless you have the specialized training and equipment for that environment.
- Stay within your training and the dive operator’s and site’s limits; specialized equipment does not substitute for training.
- Do not disturb unknown cargo, ordnance, tanks or chemical containers.
- Maintain buoyancy and streamlined equipment, and follow site-specific safety instructions.
Divers Alert Network’s wreck guidance discusses gas planning, guideline use, disorientation, silt-outs, entanglement and environmental hazards. NOAA’s sanctuary diving guidance likewise advises divers to penetrate only when specifically trained. Neither source can certify an individual diver’s readiness.

A wreck or guideline reel can be part of navigation and maintaining an exit route during trained wreck penetration. It is not an artifact-recovery tool, does not make an untrained penetration safe, and provides no legal permission to collect.

When is collection appropriate?
Collection is not a safe default just because an artifact appears loose, abandoned or easy to lift. Leave it in place unless the authority with jurisdiction confirms that recovery is permitted for that wreck and that your proposed purpose and method meet the applicable conditions. Where recovery is authorized, it may require a documented conservation or research plan, qualified professionals, reporting, curation and public access. A souvenir or sale motive is not a substitute for authorization.
