DOHSA Explained: How Wrongful Death at Sea Is Compensated Under Federal Law

1. What DOHSA is, in plain terms

If you are reading this after losing someone, we are sorry. The goal here is not to add legal stress to an already painful time, but to give you a clear, honest map of how these claims work, because the rules offshore are genuinely different from the wrongful death rules onshore, and the differences matter.

The Death on the High Seas Act was passed in 1920, the same year as the Jones Act, to give the families of people killed far out at sea a way to recover. Before it existed, a death on the open ocean often left a family with no remedy at all. DOHSA filled that gap. But it filled it in a specific, limited way that reflects its era, and Congress has changed it only narrowly since.

2. The high seas line: three nautical miles

The first question in any death at sea is where it happened, because location decides which law applies. As a general rule, DOHSA governs deaths that occur more than three nautical miles from the shore of the United States. That three-mile line is the hinge the entire case turns on.

Beyond three miles, on what the law calls the high seas, DOHSA usually controls and displaces other remedies. Within three miles, in state territorial waters, DOHSA generally does not apply, and state wrongful death law or general maritime law steps in instead. As we explain below, those other frameworks often allow a broader range of damages than DOHSA does, which is why the location is not a technicality. It can change what a family is allowed to recover.

3. Who can bring the claim

DOHSA does not let just anyone file. The claim is brought by the personal representative of the person who died, acting on behalf of a defined group of family members: the surviving spouse, children, parents, or a dependent relative. The recovery belongs to those beneficiaries, not to the estate generally.

In practice the personal representative is often a spouse or adult child who has been appointed to handle the estate. If no representative has been named yet, that is one of the first steps, because the claim is filed in the representative's name. Sorting out who the proper beneficiaries are, and making sure each one's losses are accounted for, is straightforward in many cases but can become contested in blended families, which is another reason to get clear guidance early. If you are just beginning, our overview of a wrongful death at sea claim lays out the steps in order.

4. What DOHSA pays: pecuniary losses

DOHSA compensates pecuniary losses, which is the law's term for measurable financial harm the family suffered because of the death. The recoverable categories generally include:

• Lost financial support. The income and support the person would reasonably have provided to the family over their working life.
• Lost services. The value of the practical things the person did for the household, from childcare to maintenance, now lost.
• Loss of inheritance. In appropriate cases, the value of what the person would likely have accumulated and left to the family.
• Loss of nurture and guidance. For surviving children, courts recognize the monetary value of the parental training, instruction, and guidance the child will no longer receive.
• Funeral expenses in some circumstances, where they were borne by a dependent.

These categories can add up to a substantial number, especially when the person was a primary earner with dependents and many working years ahead. But every one of them shares a common thread: it can be measured in dollars. That is the boundary of what DOHSA allows.

5. What DOHSA does not pay

Here is the part that blindsides families, and the reason understanding a DOHSA wrongful death claim early matters so much. Because the statute limits recovery to pecuniary losses, courts have read it to exclude the losses that often feel the most real.

The Supreme Court confirmed this narrow reading in Mobil Oil Corp. v. Higginbotham, holding that DOHSA's pecuniary limit controls and cannot be supplemented with damages for loss of society for a death on the high seas. It is a hard rule, and it is not the family's fault for not knowing it. It is simply how the 1920 statute was written, and it is exactly why the location of the death and the identity of the person carry so much weight.

6. How pecuniary loss is calculated

Because the recovery is financial, the claim is built with financial evidence. A serious case is typically supported by an economist who projects the income and benefits the person would have provided over their remaining work life, adjusted for personal consumption and reduced to present value. Vocational and family evidence fills in the rest: the person's earning trajectory, the services they performed for the household, and, where children survive, the value of the guidance they will grow up without.

This is also why documentation matters. Pay history, tax records, the person's role in the family, and credible projections are what turn a loss into a number a defendant and a court will take seriously. The work is painstaking, but it is the heart of a DOHSA claim.

7. When the person was a Jones Act seaman

If the person who died was a crew member of a vessel, a Jones Act seaman, the analysis adds another layer. A seaman killed on the high seas may have claims under both the Jones Act, which allows a negligence claim against the employer, and DOHSA. The two statutes overlap, and how they fit together has been worked out by the courts.

In Miles v. Apex Marine Corp., the Supreme Court adopted a principle of uniformity: when a seaman dies, the recovery is generally held to pecuniary losses, keeping the result consistent across the Jones Act, DOHSA, and general maritime law. That means the harsh pecuniary limit usually follows the seaman's family even where more than one statute is in play. The value drivers in these cases overlap heavily with the factors that shape any offshore claim, which we cover in detail in how offshore injury claim value is determined.

8. Deaths within three miles of shore

When a death happens within three nautical miles of shore, the picture can change significantly, and often for the better from the family's perspective. DOHSA generally does not reach into state territorial waters, so state wrongful death statutes or general maritime law may govern instead, and many of those allow recovery for losses DOHSA bars, including loss of society and companionship.

The Supreme Court addressed this in Yamaha Motor Corp. v. Calhoun, allowing state wrongful death remedies to apply to the death of a recreational user in territorial waters. The result is that the same kind of accident can carry very different available damages depending on whether it happened just inside or just outside the three-mile line.

This is one more reason the location of the death is investigated so carefully. A few miles can be the difference between a pecuniary-only claim and one that recognizes the family's full loss.

9. The commercial aviation exception

There is one notable carve-out. After the loss of life in offshore commercial plane crashes prompted reform, Congress amended DOHSA in 2000 to treat commercial aviation differently. For a death caused by a commercial aviation accident more than twelve nautical miles from shore, families may recover certain non-pecuniary damages, specifically loss of care, comfort, and companionship, that the statute otherwise bars.

The exception is narrow. It applies only to commercial aviation, it uses a twelve-mile line rather than three, and it still does not permit punitive damages. For the maritime accidents most offshore families face, the general pecuniary-only rule remains the one to plan around. But for an aviation loss at sea, this provision can materially change what is available.

10. Deadlines, investigations, and evidence

Time works against these claims in two ways. First, there is a filing deadline. Maritime wrongful death claims generally carry a three-year limit, though the exact deadline can depend on the defendant and the theory, and some related deadlines are shorter. Missing it can end a claim regardless of its merit.

Second, the evidence at sea is fragile. Vessel position logs, maintenance records, crew statements, weather data, and the findings of Coast Guard or other official investigations are central to proving what happened and who was responsible, and they are easiest to secure early. Once a vessel returns to service and time passes, that evidence becomes harder to gather. Acting promptly is not about rushing a grieving family. It is about protecting the record while it still exists.

11. How a claim is built

A claim like this is part legal analysis and part careful accounting, and it benefits enormously from someone who has handled them before. The work involves pinning down the location and the applicable law, identifying the proper representative and beneficiaries, preserving the offshore evidence, and assembling the economic proof of the family's pecuniary loss. An experienced maritime wrongful death attorney does each of these things while the family is given room to grieve.

Specialization matters here more than in ordinary injury law, because the rules are unusual and the mistakes are costly. Choosing the wrong framework, missing a beneficiary, or letting evidence slip can quietly reduce or even end a valid claim. If you are weighing your options, it helps to understand the broader landscape of maritime claims, which you can explore through our maritime case types, and then talk with someone who concentrates in this area.

12. What to do now

There is no good time to deal with a legal claim after losing someone, but a few early steps protect your family's rights without demanding much of you. Preserve anything you have: documents, the names of people who were there, official notices, and any correspondence from the company or its insurer. Avoid giving recorded statements or signing anything before you understand what such a claim involves. And have the situation reviewed before the deadline and before the evidence fades.

If you would like that review, you can speak with a vetted maritime attorney confidentially and at no cost. The point is not to pressure you. It is to make sure that a law written a century ago, and the limits it imposes, do not catch your family by surprise at the worst possible time.

Nothing about this brings back the person you lost. What it can do is make sure that the support, the services, and the future they would have provided are not lost twice, once to the accident and again to a rule no one explained.
