Death on the High Seas Act: What It Covers and What It Means for Aviation Families

If Your Loved One Died at Sea: Which Deaths the Death on the High Seas Act Covers

If a loved one died offshore, the first question is usually whether this federal law reaches the loss at all. The Death on the High Seas Act (DOHSA) is a chapter of federal law that takes its name from 46 U.S.C. § 30301, which says the chapter "may be cited as the 'Death on the High Seas Act'."

Under 46 U.S.C. § 30302, the statute reads: "When the death of an individual is caused by wrongful act, neglect, or default occurring on the high seas beyond 3 nautical miles from the shore of the United States, the personal representative of the decedent may bring a civil action in admiralty against the person or vessel responsible. The action shall be for the exclusive benefit of the decedent's spouse, parent, child, or dependent relative."

Three pieces of that sentence do most of the work. First, the place: the wrongful act, neglect or default must occur on the high seas beyond 3 nautical miles from the U.S. shore. Second, the person who files: a personal representative, meaning the person authorized to act on behalf of the decedent's estate. Third, the people the case is for: the spouse, parent, child or dependent relative, and no one else.

"Civil action in admiralty" means the case would not be an ordinary state-court wrongful-death suit; it would be brought under the federal law that governs maritime matters. That shift changes who files, who benefits and what the law measures. Whether the act, neglect or default was wrongful, and who is responsible, are questions the facts decide; a crash on its own proves neither.

The stakes are practical. A relative who is not the personal representative may find that someone else is the one who formally brings the case on the family's behalf, and a relative outside the listed group is not among those the case is for. Identifying the personal representative and the beneficiaries is often an early step, and one a conversation with an attorney can help sort out.

When a Plane Goes Down Over Open Ocean

Congress wrote aviation directly into the statute. 46 U.S.C. § 30307 is titled "Commercial aviation accidents," and it sets two distance rules for a crash that involves commercial aviation.

Beyond 12 nautical miles from the U.S. shore, DOHSA applies to a death resulting from a commercial aviation accident, with additional damages discussed in the next section. At 12 nautical miles or less, the text states plainly: "This chapter does not apply if the death resulted from a commercial aviation accident occurring on the high seas 12 nautical miles or less from the shore of the United States."

That creates a layered map. For deaths generally, the line in § 30302 is 3 nautical miles. For deaths from a commercial aviation accident, the chapter does not apply at 12 nautical miles or less. The same ocean crash could be treated very differently depending on how far offshore it occurred and whether the flight was a commercial aviation flight.

Neither fact is always clear in the first days. The location may come from radar, wreckage recovery or investigators' work, and whether a flight counts as a "commercial aviation accident" can depend on how it was operated. Families with a loss near the water, including those involving seaplane crashes or cargo plane crashes, often find that the location question comes first because it shapes everything after it.

What a Family May Recover Under DOHSA — and the Limits That Matter

The baseline measure is narrow. Under 46 U.S.C. § 30303, "The recovery in an action under this chapter shall be a fair compensation for the pecuniary loss sustained by the individuals for whose benefit the action is brought." Pecuniary loss means a financial loss, one that can be measured in money. The court divides any recovery among the beneficiaries "in proportion to the loss each has sustained."

For many families, the hardest part of a loss is not financial. Outside the commercial aviation setting, grief and the loss of a loved one's presence are not what this measure counts. Section 30307 changes that in one setting. It defines "nonpecuniary damages" as "damages for loss of care, comfort, and companionship," and provides that if the death resulted from a commercial aviation accident on the high seas beyond 12 nautical miles from the U.S. shore, "additional compensation is recoverable for nonpecuniary damages, but punitive damages are not recoverable."

So in a commercial aviation death beyond 12 nautical miles, the law may allow pecuniary loss plus loss of care, comfort and companionship, and it bars punitive damages, which are meant to punish rather than to compensate. Whether a flight was commercial, and how far out it went down, can decide whether the loss of companionship is part of the picture at all.

Fault can also reduce what the law allows. 46 U.S.C. § 30304 says the decedent's contributory negligence "is not a bar to recovery," but the court "shall consider the degree of negligence of the decedent and reduce the recovery accordingly." What any family may recover depends on the facts and the proof, and no page can predict it.

If the Crash Happened Near Shore: Where State Law Still Shapes a Family's Options

DOHSA is a federal layer, and the statute itself speaks to state law. 46 U.S.C. § 30308(a) states: "This chapter does not affect the law of a State regulating the right to recover for death." How courts have applied that sentence alongside DOHSA in particular cases can turn on where and how a death occurred.

A death that falls outside DOHSA, such as a commercial aviation death 12 nautical miles or less from shore, is left to other law, which may include a state's wrongful-death statute. Claims against an aircraft or component manufacturer, a maintenance provider or an operator can also involve state tort and product-liability theories, meaning claims built on negligence or on a defective product. Admiralty jurisdiction over a DOHSA claim does not, by itself, erase those separate theories.

The state rules are not uniform. Limitation periods, comparative or contributory fault rules, wrongful-death rules and damages rules differ from state to state, and which state's law could matter, if any, depends on the facts of the flight and the parties. For a family, the deadlines and the kinds of loss counted may differ from DOHSA's, and an attorney can help map which rules could reach a particular loss. Our page on aviation wrongful death claims explains the state-law side in more depth.

There is also a foreign layer. Under 46 U.S.C. § 30306, when a foreign country's law gives a cause of action for a death on the high seas, a civil action in admiralty may be brought in a U.S. court on that foreign cause of action, "without abatement of the amount for which recovery is authorized." For families of a flight with foreign connections, that can widen the set of laws worth reviewing.

If the Loss Falls Outside the Act: When DOHSA Does Not Apply

A crash in a lake, a bay or close to shore, or a crash someone survived, may sit entirely outside DOHSA. Section 30308(b) says the chapter "does not apply to the Great Lakes or waters within the territorial limits of a State." Together with the 3-nautical-mile line in § 30302 and the 12-nautical-mile rule for commercial aviation in § 30307, those limits mark where DOHSA stops. In those cases, a family's options come from other law, not from this statute's damages rules.

DOHSA is a death statute. Its cause of action in § 30302 arises "when the death of an individual is caused" by a wrongful act, neglect or default. If you survived a crash with injuries, or a loved one did, that claim is not a DOHSA claim; other admiralty or state-law rules govern it. One section bridges the two: under 46 U.S.C. § 30305, if a federal admiralty injury case is pending and the injured person dies from the same wrongful act, neglect or default, the personal representative "may be substituted as the plaintiff" and the case may proceed under DOHSA.

Families sometimes hear other maritime laws mentioned, and they are separate. If the person who died was working as a seaman, the Jones Act, 46 U.S.C. § 30104, may be relevant: it lets "a seaman injured in the course of employment," or the seaman's personal representative after a death, "elect to bring a civil action at law, with the right of trial by jury, against the employer." For a passenger's or pilot's family, it is not a claim by default. The Suits in Admiralty Act is another distinct federal maritime statute, not part of DOHSA.

The stakes here are about framing: assuming DOHSA applies simply because the crash involved water can point a family toward the wrong rules. A useful next step is pinning down the crash location, whether anyone survived, and the decedent's role on board, then reviewing with an attorney which framework those facts fit.

Questions Worth Asking Before Pursuing a DOHSA Claim

Three factual questions shape almost everything above. Where did the aircraft go down, measured from the U.S. shore? Was the flight a commercial aviation flight? Who may be responsible, whether an air carrier or other operator, a manufacturer, a maintenance provider or someone else? The answers decide whether DOHSA applies, which damages categories the law may allow, and which limitation period governs. Limitation periods for related state-law claims differ by state, so the timing question is one families often raise early with an attorney.

The official investigation is often the first source of facts. The National Transportation Safety Board (NTSB) investigates civil aviation accidents. It may issue a preliminary report, which describes early facts and is not a finding of cause; a probable cause is stated only in the final report. Federal law limits how those reports are used in court. Under 49 U.S.C. § 1154(b), "No part of a report of the Board, related to an accident or an investigation of an accident, may be admitted into evidence or used in a civil action for damages resulting from a matter mentioned in the report." The same section restricts discovery of cockpit recorder recordings and unreleased transcripts, allowing a court to permit it only under the conditions the statute sets.

Because the NTSB's report cannot carry a civil case, other records tend to matter. Families often gather the death certificate and estate papers, the ticket or booking record and passenger manifest, correspondence with the operator or its insurer, any reported crash location, and maintenance or flight records as they become available. A plane crash lawsuit usually turns on evidence like this.

If you are sorting out whether the crash location, the type of flight and the possible defendants point toward DOHSA, state law or both, you may want to consider a conversation through our case evaluation page about how those layers fit together.
