Death on the High Seas Act (DOHSA) Lawyer for Families of Maritime Workers

The Young Firm is a New Orleans maritime law firm that concentrates on Jones Act and maritime injury claims for workers along the Louisiana and Gulf Coast waterfront and offshore. When a family contacts a maritime lawyer after a death at sea, whether DOHSA governs is part of the initial legal review, and it is the lawyer’s job to sort that out, not yours. A DOHSA review looks at four things: where the fatal incident occurred, what caused it, who has legal authority to bring the claim, and which losses the law allows the family to recover. Each of those questions has a specific answer under the statute, and each one depends on facts that a lawyer can often piece together even when a family has very little to start with.

This page explains how DOHSA works, where its limits are, and what a family can reasonably do in the first weeks after a loss. It is written for the specific situation DOHSA addresses: a death caused by wrongful conduct on the high seas beyond three nautical miles from the shore of the United States, with separate rules for commercial aviation. That threshold is DOHSA’s own, and it is not interchangeable with every boundary used for state waters. If you are not sure the death happened offshore, or you want to understand the full range of maritime death claims, our overview of maritime wrongful death claims is the better starting point. Either way, nothing here asks you to diagnose your own case, and you can reach The Young Firm by phone or through the inquiry options on this site whenever you are ready to talk.

What DOHSA Covers—and Why the Accident’s Location Matters

The Death on the High Seas Act is a federal wrongful-death statute codified at 46 U.S.C. Chapter 303 (46 U.S.C. §§ 30301–30308). It gives certain family members a civil remedy when a death is caused by negligence or other wrongful conduct on the high seas. The core of the statute is short, and its terms do most of the work in any case, so it is worth stating them plainly.

DOHSA in one paragraph. Under 46 U.S.C. § 30302, when the death of an individual is caused by wrongful act, neglect, or default occurring on the high seas beyond three nautical miles from the shore of the United States, the decedent’s personal representative may bring a civil action in admiralty against the person or vessel responsible. The action is for the exclusive benefit of the decedent’s spouse, parent, child, or dependent relative. Under § 30303, recovery is a fair compensation for the pecuniary loss those beneficiaries sustained, apportioned by the court according to each person’s loss. Commercial aviation accidents are treated differently under § 30307.

Three features of that rule matter most to families.

The location rule. DOHSA applies to deaths caused by conduct “on the high seas beyond 3 nautical miles from the shore of the United States.” Section 30308(b) confirms the flip side: the chapter does not apply to the Great Lakes or to waters within the territorial limits of a State. The three-nautical-mile line is DOHSA’s own statutory measure. It is not the same thing as every boundary used for state waters, federal offshore leasing blocks, or fisheries regulation, and a lawyer should confirm the legally relevant shoreline or baseline rather than assume it. For a death on the inland Mississippi River, in a Louisiana bayou, or in a port, DOHSA does not apply simply because the deceased was a maritime worker; other maritime death remedies may, and they are covered on maritime wrongful death claims.

The wrongful-conduct requirement. DOHSA is a fault-based tort statute, not an insurance program. It does not pay automatically because a death occurred offshore. The family must prove that a wrongful act, neglect, or default caused the death, and must identify the person or vessel responsible.

The damages qualification. DOHSA’s ordinary measure of recovery is pecuniary loss, meaning the financial losses the statutory beneficiaries actually sustained. That is a narrower measure than many state wrongful-death laws, and it shapes every part of the analysis that follows.

One more point clears up a common misunderstanding: DOHSA is not limited to Jones Act seamen. It reaches deaths of passengers, contractors, and other workers on the high seas, as long as the statute’s location and causation requirements are met. Whether the deceased was a seaman matters for a different reason, discussed below, because seaman status can add a Jones Act claim against the employer.

Offshore Injury, Later Hospital Death, or Fixed Platform: Different Facts Can Change the Law

Families often assume that “offshore” answers the DOHSA question. It does not. The same Gulf of Mexico fatality can fall under DOHSA, under the Jones Act, under the Outer Continental Shelf Lands Act with adjacent state law, or under some combination, depending on facts that are not always obvious in the first phone call. The examples below are illustrations of the analysis, not descriptions of firm cases.

Two details from this table deserve emphasis.

First, the statute also addresses what happens when a worker files a personal injury suit and then dies of those injuries while the case is pending. Under 46 U.S.C. § 30305, the personal representative may be substituted and the action continued under DOHSA. Families sometimes do not realize an existing injury case can be carried forward in this way.

Second, the vessel-versus-platform distinction is not academic. Jack-up rigs, drillships, liftboats, and semisubmersibles are often treated as vessels; fixed production platforms bolted to the seabed are not. Which category the structure falls into can change the governing law entirely. For the broader picture of fatal offshore accidents and the remedies that may apply to them, see offshore wrongful death. This page limits the discussion to how those facts affect DOHSA.

Who Files a DOHSA Lawsuit, and Which Family Members May Benefit?

DOHSA separates two roles that families understandably blend together: the person who files the lawsuit and the people the lawsuit is for.

The personal representative is the person with legal authority to act on behalf of the deceased’s estate. Under § 30302, only the personal representative may bring the DOHSA action. In practice this usually means someone appointed by a court through a succession or probate proceeding, though the details depend on the applicable procedure. A spouse or parent is not automatically the personal representative simply by relationship.

The statutory beneficiaries are the people for whose exclusive benefit the action is brought: the decedent’s spouse, parent, child, or dependent relative. The statute’s wording is deliberate. A spouse, parent, or child qualifies by relationship. Any other relative, such as a sibling or grandparent who relied on the deceased, must show dependency. Not every relative qualifies, and the proof required is not identical across categories.

Being a beneficiary establishes the right to share in a recovery; it does not establish an amount. Under § 30303, the court apportions the recovery among the beneficiaries in proportion to the pecuniary loss each one sustained. A dependent minor child and an adult child who was financially independent stand in very different positions under that language, even though both are “children.”

Families do not need to complete the appointment of a personal representative before speaking with a lawyer. Early conversations are about learning the facts, identifying urgent dates, and preserving evidence. A lawsuit, however, cannot properly proceed until someone with authority to file it has been appointed, and that step should be planned rather than assumed. The appointment process, disputes among relatives, and the broader set of questions families face are covered in family rights after a maritime death.

DOHSA Compensation Usually Focuses on Financial Loss—not Every Consequence of the Death

The hardest part of explaining DOHSA to a grieving family is the damages rule. Section 30303 provides that recovery “shall be a fair compensation for the pecuniary loss sustained” by the beneficiaries. In Mobil Oil Corp. v. Higginbotham, 436 U.S. 618 (1978), the Supreme Court held that where DOHSA applies, general maritime law cannot be used to add damages for loss of society that the statute does not provide. And in Dooley v. Korean Air Lines Co., 524 U.S. 116 (1998), the Court held that a general maritime survival action for the decedent’s pre-death pain and suffering is likewise unavailable in a case governed by DOHSA.

In plain terms: in a vessel-death case governed by DOHSA, the statute itself does not compensate grief or loss of companionship, and general maritime law cannot be used to add damages for the deceased’s own suffering before death. That limit is about DOHSA and attempts to supplement it under general maritime law. It does not, by itself, decide what an independent statutory remedy provides. Where the deceased qualified as a seaman, the Jones Act claim against the employer has its own damages rules, addressed on Jones Act wrongful death claims; whether any pre-death loss is recoverable in a particular case depends on which claims are actually available, and no family should be promised that recovery in advance. The limits on pre-death losses are explored in more depth on the maritime survival actions page. The commercial aviation provision discussed in the next section permits certain family losses in qualifying aviation cases; it does not authorize damages for the deceased’s own pain and suffering. Attaching a state-law or general-maritime label to a claim does not avoid these restrictions when DOHSA governs; Offshore Logistics, Inc. v. Tallentire, 477 U.S. 207 (1986), rejected the use of state wrongful-death law to supplement DOHSA remedies for a high-seas death.

None of this means a DOHSA claim is small or unimportant. Pecuniary loss, properly proven, can represent decades of a family’s financial life. What it means is that the claim is built on evidence rather than on the obvious depth of the loss, and that evidence is often in records the family already has.

The categories below are the financial losses most commonly examined in a DOHSA case. Each must be proven for each beneficiary and confirmed against controlling authority in the governing jurisdiction; the table describes what a lawyer evaluates, not an entitlement.

A few points about this table.

Lost support is not the same as the deceased’s total projected gross earnings. The calculation generally accounts for what the deceased would have consumed personally, for taxes, and for work-life expectancy, and it is usually the subject of expert economic testimony. Families should be cautious about back-of-the-envelope figures from any source, including well-meaning friends, and should not expect a lawyer to quote a value before the evidence has been assembled.

Each category must be proven for each beneficiary. Because the court apportions the recovery by individual loss, the evidence has to show who depended on the deceased and how. That is why payroll records and a candid account of the household’s finances are among the most valuable things a family can gather.

Funeral expenses are not listed above because their treatment depends on who paid them and which claims are available in the case; keep the invoices and proof of payment, but expect that question to be analyzed individually rather than answered by a general rule. Offsets, the treatment of any benefits already paid, and the interaction with other claims are likewise case-specific questions.

Commercial Aviation Has Different DOHSA Distance and Damages Rules

Offshore workers often travel to and from the job by helicopter, so families should know that DOHSA treats commercial aviation deaths under a separate provision, 46 U.S.C. § 30307. That section changes both the distance rule and the damages rule, and it is easy to misapply in either direction.

Beyond 12 nautical miles. If the death resulted from a commercial aviation accident occurring on the high seas beyond 12 nautical miles from the shore of the United States, § 30307(b) allows recovery of nonpecuniary damages in addition to pecuniary loss. The statute defines nonpecuniary damages as damages for loss of care, comfort, and companionship (§ 30307(a)). These are the family’s own losses; the provision does not create a claim for the deceased’s pre-death suffering. It also expressly states that punitive damages are not recoverable. Nonpecuniary damages compensate the family for what it lost; punitive damages punish the defendant. DOHSA allows the first in qualifying aviation cases and never the second.

Twelve nautical miles or closer. Under § 30307(c), DOHSA does not apply at all to a commercial aviation accident occurring 12 nautical miles or less from the shore. In that zone, the family’s remedies come from other law, potentially including state wrongful-death law and general maritime law, which is a very different landscape from the DOHSA vessel-death rule described above.

Two cautions. First, not every offshore helicopter operation is necessarily a “commercial aviation accident” within the meaning of § 30307; classification of a particular flight requires fact-specific analysis. Second, the leading Supreme Court decision involving an offshore helicopter death, Tallentire, was decided in 1986, before the aviation provisions took their current form, and must be read alongside the current statutory text. If your family’s loss involved a helicopter, the safest assumption is that the analysis is different from a vessel death and needs its own review. The broader treatment of fatal offshore transport and worksite accidents is on the offshore wrongful death page.

DOHSA and Other Maritime Claims Are Not Always an Either-Or Choice

A single death can implicate more than one legal framework, and a careful lawyer screens all of them rather than assuming the first label that fits is the only one.

The Jones Act. If the deceased qualified as a seaman, 46 U.S.C. § 30104 gives the personal representative a negligence claim against the employer for the seaman’s death. That claim exists independently of DOHSA and does not depend on the three-nautical-mile line. When a seaman dies on the high seas, the Jones Act claim against the employer and a DOHSA claim, often against a non-employer vessel owner or operator, may proceed together. Whether the deceased was a seaman is its own question, addressed in detail on Jones Act seaman status, and the standards for the employer claim are covered on Jones Act wrongful death claims.

Longshore and harbor worker benefits. Some offshore workers are covered not by the Jones Act but by the Longshore and Harbor Workers’ Compensation Act, in some cases through OCSLA’s extension of that statute. LHWCA death benefits are a no-fault compensation system, paid regardless of negligence. They are not a substitute for a DOHSA tort action and should not be confused with one; a family may need both a benefits review and a liability review. See Longshore & Harbor Worker Claims for the benefits side.

Third-party claims. DOHSA’s defendant is “the person or vessel responsible.” In offshore operations that is frequently not the employer but a vessel owner, charterer, contractor, or equipment manufacturer. Identifying every potentially responsible party is part of any complete assessment.

Survival and state-law claims. As noted above, Higginbotham, Dooley, and Tallentire limit the ability to layer general maritime or state-law damages on top of DOHSA in a case DOHSA governs. Overlapping theories do not multiply damages, and duplicate recovery for the same loss is not permitted. The practical value of coordinating claims lies in reaching every responsible party and every category of loss the law actually allows, not in stacking labels. The details of what survives the death and when are on the maritime survival actions page, and the general map of maritime death remedies is on maritime wrongful death claims.

Proving Responsibility—and Responding When the Deceased Worker Is Blamed

DOHSA requires proof that a wrongful act, neglect, or default caused the death. In the offshore setting, that proof typically comes from operational evidence: who directed the work, what procedures applied, what condition the vessel and equipment were in, what the weather and sea state were, and what decisions were made in the hours before the incident. Responsibility follows operational roles, not company logos. The name on the worker’s paycheck may be one defendant; the company that owned the vessel, the company that chartered it, and the company that supplied or maintained the equipment may be others.

Families are sometimes told, informally or in writing, that the worker caused his own death. That statement should be treated as an allegation, not a finding. Two things follow.

First, an allegation of fault does not end a DOHSA claim. Section 30304 provides that the contributory negligence of the decedent is not a bar to recovery; instead, the court considers the degree of the decedent’s negligence and reduces the recovery accordingly. Even if a factfinder ultimately assigns some fault to the worker, the family’s claim survives, reduced rather than eliminated.

Second, the evidence that would establish fault is usually in the hands of the companies involved, which is why early preservation matters. Vessel logs, navigation and positioning data, maintenance and inspection records, job safety analyses and permits to work, radio and email communications, and witness accounts speak to both liability and causation. They also frequently answer the location question that determines whether DOHSA applies at all.

A word about the United States Coast Guard. A Coast Guard marine casualty investigation can be an important source of information about where and how an incident happened, and families should keep any Coast Guard correspondence. But the Coast Guard investigates for safety and regulatory purposes. Its work is not a civil liability judgment, it does not decide the family’s claim, and, as discussed next, it does not pause the family’s deadlines. Where the responsible party is not the employer, the analysis continues on our third-party maritime injury claims page.

DOHSA Deadlines: Why the General Three-Year Rule Is Not a Safe Waiting Period

The general limitations statute for maritime torts, 46 U.S.C. § 30106, provides that a civil action for damages for personal injury or death arising out of a maritime tort must be brought within three years after the cause of action arose, “except as otherwise provided by law.” Three years sounds like ample time. Families should not treat it that way, for several reasons.

Accrual can be disputed. A wrongful-death claim is often measured from the date of death, but the point at which a cause of action “arose” can be contested, particularly where injury and death were separated in time. No one should calculate a deadline from an assumed start date.

Other deadlines can be much shorter. Vessel owners facing a serious casualty sometimes file a limitation-of-liability proceeding in federal court. When that happens, the court sets a date by which all claimants must file their claims in that proceeding, and that date can arrive within months, not years. Notices of such proceedings are sometimes published rather than mailed. Claims against the United States or a government-owned vessel are governed by separate statutes with their own, generally shorter, limitations periods. Contracts, insurance policies, and benefit programs may impose their own notice requirements.

Investigations do not stop the clock. A pending Coast Guard, employer, or insurer investigation does not pause the limitations period. Nor should a family assume that a beneficiary’s minority, the time needed to appoint a personal representative, or an ongoing settlement discussion tolls the deadline. Those questions have specific answers in specific cases, and none of them is a safe assumption.

Evidence has its own timeline. Electronic navigation data can be overwritten. Vessels sail, are repaired, or change hands. Crew members scatter to other jobs. The urgency of preserving evidence is independent of the filing deadline and is often the more pressing of the two in the first weeks after a death.

The practical instruction is simple: if any court paper, claim notice, release, or deadline letter reaches your family, share it with a lawyer promptly rather than setting it aside until the funeral and the estate are handled. Broader guidance on managing these early steps is on the family rights after a maritime death page.

What Your Family Can Share Now—and What Counsel Can Investigate

Families sometimes delay calling a lawyer because they believe they need coordinates, an official report, or a complete financial file first. They do not. The initial inquiry can begin with what you already know, and the technical records can be pursued through proper channels afterward.

Information most families already have

• The deceased’s full name, date of birth, and the approximate date of the incident
• The employer’s name and any staffing company, crewing agency, or contractor involved
• The name of the vessel, rig, platform, or worksite, if known, even approximately
• Any letters, emails, texts, or calls from the employer, its insurer, or its lawyers, including anything asking you to sign
• Any notice from a court, the Coast Guard, or another agency
• Existing reports you have been given, such as an incident report or death certificate
• Names and contact information for crew members or coworkers who have reached out
• Pay stubs, tax returns, benefit statements, and anything showing the deceased’s financial contributions to the household
• Documents showing who has been, or is expected to be, appointed to handle the estate

Records counsel can seek through lawful channels

• Vessel position and navigation data establishing where the incident occurred, which answers the DOHSA location question
• Marine casualty records and related agency files, which address circumstances and sequence
• Deck, engine, and bridge logs, maintenance and inspection records, and equipment certifications, which address responsibility and causation
• Job safety analyses, permits to work, standing orders, and operational communications, which show what was directed and by whom
• The medical chronology from injury to death, including evacuation records, which matters for both causation and the delayed-death analysis
• Employment and payroll records from the employer, which support the pecuniary-loss calculation

Availability of these records depends on the source and on lawful access, and some will come only through formal discovery once a claim is filed. What families should not do is attempt to obtain evidence themselves in ways that are unsafe or unauthorized: boarding a vessel, pressuring coworkers who fear for their jobs, or accessing company systems. Keep originals of everything you have, and ask how the lawyer prefers to receive copies of sensitive documents rather than sending originals. Do not sign releases or give recorded statements to an insurer before speaking with a lawyer. The family’s role in the first weeks is to preserve and share, not to investigate.

How a DOHSA Lawyer Turns Incomplete Information Into a Claim Assessment

It may help to understand what actually happens with the information above, because the review is more than a checklist.

A vessel name and an employer are usually enough to start. The vessel’s identity leads to its ownership and charter arrangements, and through position data and logs to its location at the relevant time. That location is then measured against the statutory three-nautical-mile line and the state territorial exclusion in § 30308(b). If the structure turns out to be a fixed platform rather than a vessel, the analysis pivots to OCSLA; if the death followed a helicopter flight, it pivots to § 30307. The same records that fix the location typically begin to answer who directed the work, what failed, and which companies stood in which roles, so the location inquiry and the liability inquiry proceed together rather than in sequence.

Location does not have to be resolved before anything else can happen. Preservation demands, deadline review, and identification of the statutory beneficiaries proceed at the same time, because the earliest deadline in a case is often unrelated to the DOHSA question, and because evidence does not wait for jurisdiction to be settled.

The reason to hire a lawyer who works in maritime law specifically is that these questions depend on one another. An error in one, such as assuming a platform was a vessel or assuming a spouse could file without appointment as personal representative, distorts the rest. The Young Firm’s practice is concentrated on maritime injury and death claims arising from Gulf Coast and offshore work; broader information about the firm and its lawyers is available on our home page.

Legal Authorities for This DOHSA Guide

This guide is general legal information. It cannot determine whether DOHSA applies to a particular death, who the beneficiaries are, what a claim is worth, or when it must be filed. Those answers require review of the specific facts by a lawyer.

The propositions on this page rest on the following authorities, which should be read in their current form:

• 46 U.S.C. § 30302 — cause of action, the three-nautical-mile location rule, the personal representative’s authority, and the spouse, parent, child, or dependent relative beneficiary classes.
• 46 U.S.C. § 30303 — pecuniary-loss measure of recovery and apportionment among beneficiaries.
• 46 U.S.C. § 30304 — contributory negligence of the decedent reduces rather than bars recovery.
• 46 U.S.C. § 30305 — continuation of a pending personal injury action as a DOHSA action after the plaintiff’s death.
• 46 U.S.C. § 30307 — commercial aviation accidents: definition of nonpecuniary damages, the beyond-12-nautical-mile rule allowing nonpecuniary but not punitive damages, and the nonapplication of the chapter to aviation accidents 12 nautical miles or closer.
• 46 U.S.C. § 30308 — subsection (a) addresses the chapter’s effect on state law governing the right to recover for death; subsection (b) excludes the Great Lakes and waters within the territorial limits of a State from the chapter’s coverage. How subsection (a) interacts with the limits on supplementing a DOHSA recovery is the subject of Tallentire, below.
• 46 U.S.C. § 30106 — general three-year limitations period for maritime personal injury and death actions, subject to other provisions of law.
• 46 U.S.C. § 30104 — the Jones Act death remedy for seamen against their employers.
• ***Mobil Oil Corp. v. Higginbotham*, 436 U.S. 618 (1978)** — no supplementation of DOHSA pecuniary damages with general maritime loss-of-society damages.
• ***Offshore Logistics, Inc. v. Tallentire*, 477 U.S. 207 (1986)** — state wrongful-death law does not supplement DOHSA remedies for a high-seas death; decided before the current aviation provisions and to be read with them.
• ***Dooley v. Korean Air Lines Co.*, 524 U.S. 116 (1998)** — no general maritime survival action for pre-death pain and suffering where DOHSA governs.
• ***Rodrigue v. Aetna Casualty & Surety Co.*, 395 U.S. 352 (1969)** — fixed offshore platforms are governed by OCSLA and adjacent state law rather than DOHSA.

Statutory text changes, and older decisions, especially those involving aviation, must be read against subsequent amendments and later controlling authority in the relevant federal circuit. Statements on this page about how courts have treated delayed deaths, nurture and guidance, and funeral expenses describe general patterns that must be confirmed for the governing jurisdiction before they are relied on in any case.

Ask The Young Firm to Review a Possible DOHSA Claim

If you have lost a husband, wife, parent, child, or someone who supported you, and the death happened at sea, you can contact The Young Firm by phone or through the inquiry options on this site to talk through what you know. You do not need to know whether DOHSA applies. You do not need coordinates, an official report, or a completed estate proceeding. A name, an employer, a vessel or worksite, an approximate date, and whatever paperwork has arrived are enough to begin.

A first conversation with a maritime lawyer is generally about listening to what happened as you understand it, asking about any letters, court notices, or requests to sign documents you have received, and identifying anything that looks time-sensitive. It should leave you with a plain-language sense of which legal frameworks appear to be involved and what would need to be investigated to confirm them. Before your family commits to anything, expect a clear explanation of fee and cost terms, and expect any agreement to represent your family to be put in writing. Contacting the firm, submitting an inquiry, or speaking with us does not by itself create an attorney-client relationship; representation is confirmed through a written agreement.

If it turns out your family’s loss falls outside DOHSA, because it happened in state waters, on a fixed platform, or in some other setting, that does not mean there is no claim. It means a different part of maritime law governs it, and our overview of maritime wrongful death claims explains those routes. Whichever law applies, the practical advice is the same: preserve what you have, do not sign anything you do not understand, and share any deadline notice promptly.
