Your client worked as a logistics coordinator at a forward operating base near Kandahar. He wrenched his back loading pallets in 2016. Three years later the claim finally reaches an administrative law judge, and the employer appears under a carrier name you have never seen before.
The Longshore district director already tried an informal conference. It went nowhere. Now you are in formal litigation, and the answer denies nearly everything, including coverage. The carrier is betting you cannot prove who insured the job, when, and under which policy.
This is where discovery decides the case. In a Defense Base Act claim, you rarely walk in holding the policy, the coverage dates, or the adjuster's file. You have to pull them out of an opponent who would rather you never find them. The tools are interrogatories, requests for production, requests for admission, and depositions.
Those tools run on a specific rulebook. The Defense Base Act at 42 U.S.C. 1651 to 1654 borrows the machinery of the Longshore and Harbor Workers' Compensation Act at 33 U.S.C. 901 to 950. When a DBA case goes to hearing, the Office of Administrative Law Judges runs it under 29 CFR Part 18, the OALJ Rules of Practice and Procedure. The 2015 revision of those rules pulled discovery much closer to the Federal Rules of Civil Procedure.
Most state workers' compensation practitioners underestimate how much that shift matters. This guide walks through how discovery actually works before an OALJ judge, device by device, and why your investigation should be finished before you draft the first interrogatory.
When Does Discovery Actually Start in a DBA Case Before OALJ?
Discovery does not begin when the case is filed. It begins when the case reaches a judge. Under 29 CFR 18.50(a), a party may seek discovery only after the judge issues an initial notice or order in the proceeding.
That timing is a real change from old habit. For years, Longshore and DBA litigants treated the district director's referral letter as the starting gun for discovery. The revised rule moved the start line to the judge's first notice. If you serve interrogatories off the referral alone, they are premature.
The path to that judge runs through the Office of Workers' Compensation Programs. A DBA claim is administered under 20 CFR Part 702. The district director handles the informal stage, and when the parties cannot resolve the claim, one side requests a formal hearing. The district director then refers the case to the OALJ.
It helps to understand the OWCP informal conference that precedes referral before you plan discovery, because what the parties dispute there shapes what you must prove later.
Two regulations now sit on top of each other, so the hierarchy matters. Section 18.10(a) is explicit. If a governing statute or a specific Department of Labor regulation controls a proceeding, that regulation applies, and the Part 18 rules fill only the gaps. The Longshore procedural rules at 20 CFR 702.331 and following are not displaced by Part 18.
In practice, Part 18 supplies your discovery toolkit while the Longshore rules govern the surrounding claim procedure. The two are meant to coexist, not compete. When they appear to conflict, the Longshore regulation wins and Part 18 yields.
Timing drives strategy. Because discovery opens at the judge's first notice, you want your investigation finished before that notice lands. The attorney who already knows the likely carrier, the employer's corporate aliases, and the relevant decision history can serve precise discovery on day one. For a wider view of the road ahead, study how a DBA carrier dispute moves through the OALJ process from the first notice to a federal appeal.
How Do Interrogatories and Requests for Production Work Under 29 CFR Part 18?
The DBA discovery mechanics of interrogatories, requests for production, and depositions before the OALJ follow the Federal Rules of Civil Procedure more closely than most state comp practitioners expect. Start with the written tools.
Interrogatories are written questions the other side must answer under oath. Section 18.60 governs them. Unless the judge orders otherwise, you may serve no more than 25 interrogatories, counting all discrete subparts, on any one party.
The 25-question cap forces discipline. You cannot fish. Every interrogatory should pull a specific fact you need for coverage, employment, wage, or notice. The responding party has 30 days after service to answer or object under Section 18.60.
Use interrogatories to lock down identity facts. Ask the employer to state its exact legal name, every prior name, and every subsidiary that held the contract. Ask which insurance carrier covered the worksite on the date of injury, the policy number, and the policy period. Ask who administered the claim and whether that administrator is the carrier or a third-party administrator.
Requests for production come next, under Section 18.61. That rule covers documents, electronically stored information, and tangible things. In a DBA case, the documents win or lose the coverage fight.
Ask for the declarations page and the full DBA policy in force on the injury date. Ask for the certificate of insurance, the employer's first report of injury, and any LS forms filed with OWCP. Ask for the contract or task order that required DBA coverage, along with any insurance flow-down clause.
The scope of all of this is set by Section 18.51. You may discover any nonprivileged matter relevant to a party's claim or defense, including the existence, location, and custody of documents and the identity of people who know discoverable facts. Relevance, not certainty, is the standard.
Electronically stored information deserves its own attention. Adjuster notes, claim logs, reserves, and emails often live in a claims system, not a paper file. Name those formats in your request so the carrier cannot produce a thin paper printout and call it complete.
Tie your document requests to your medical evidence strategy for overseas injury claims from the start, because the carrier's own file often contains the surveillance, the reserve worksheets, and the prior medical opinions you will need to rebut at hearing.
What Can You Get From a Deposition in a DBA Claim?
Depositions are the sharpest tool in the set. Section 18.64 authorizes depositions by oral examination. Section 18.65 allows depositions by written questions, which help when a witness sits overseas and live testimony is impractical.
In a DBA case, geography complicates everything. Your client may be a local national in Iraq. A key witness may be a site supervisor who left the country years ago. A deposition by written questions, or a remote oral deposition, can capture testimony that would otherwise vanish.
Depose the adjuster who handled the claim. The adjuster knows why the carrier denied, what the reserves were, and whether coverage was ever questioned internally. A corporate representative deposition can force the employer to identify the insuring entity when interrogatory answers stay vague.
Preserve testimony for the hearing itself. Section 18.55 governs using depositions at the hearing. A deposition of a doctor abroad, or of a witness who cannot travel, can go into evidence when the rule's conditions are met. Plan the deposition as trial testimony, not just discovery.
Preparation changes the outcome. When your own client sits for deposition, opposing counsel will probe the injury account, the work history, and any prior conditions. Careful preparation of an overseas claimant for deposition testimony keeps small inconsistencies from becoming credibility attacks at hearing.
Watch the limits. The revised rules borrow the familiar federal limit of one day of seven hours per deposition unless the judge allows more. Ask early if you expect a long corporate deposition. The judge can alter the number and length of depositions on motion.
Sequence matters here too. Depose after you have documents, not before. A declarations page in hand turns a vague coverage question into a pointed one. You want the adjuster confronted with the policy, not guessing about it.
How Do Requests for Admission and Subpoenas Sharpen the Record?
Requests for admission narrow the fight. Section 18.63 lets you ask the other side to admit or deny specific facts. Each admission you win is one less thing you have to prove at hearing.
Draft admissions to remove easy defenses. Ask the carrier to admit that a named entity was the DBA insurer on the injury date. Ask the employer to admit the worker was its employee, that the work was overseas, and that the contract required DBA coverage. A matter can be deemed admitted when the party fails to answer in time.
Requests for admission also authenticate documents. Ask the opponent to admit that the attached declarations page is genuine. That single admission can save a fight over foundation when you offer the policy at hearing.
Subpoenas reach outside the parties. Section 18.56 governs OALJ subpoenas. When the carrier or a former employer will not produce records voluntarily, you can request a subpoena for documents, deposition attendance, or hearing testimony from a nonparty.
The subpoena has teeth because the statute backs it. The Defense Base Act incorporates 33 U.S.C. 927. Under Section 927(b), if a person disobeys a lawful order, neglects to produce subpoenaed documents, or refuses to appear, the judge certifies the facts to a federal district court for contempt proceedings.
Discovery abuse has consequences short of contempt too. Section 18.57 covers a party's failure to make disclosures or to cooperate in discovery, and it authorizes sanctions. A carrier that stonewalls production risks orders that hurt its defense.
Use the enforcement tools as leverage, not as a first move. A well-drafted meet-and-confer letter that cites Section 18.57 and the contempt path in Section 927 often produces the documents faster than a motion. Judges expect you to try to resolve disputes before you file.
Every device shares one dependency. You cannot draft precise admissions, subpoenas, or interrogatories about a carrier you have not identified. That is why the record you build before discovery decides how sharp your discovery can be.
Why Does Carrier and Employer Data Determine Your Discovery Strategy?
Discovery is only as good as the target you aim it at. If you do not know the likely carrier, the employer's true corporate identity, and the decisions that already name both, your interrogatories will be broad and easy to dodge.
Start with the employer's names. A single contractor may appear under a dozen legal entities across federal records. The claim may be filed under a subsidiary you have never heard of, while the contract sits under the parent. Miss the alias and you miss the coverage.
Carriers shift over time. The insurer on a 2009 task order is often not the insurer on the 2016 renewal. Coverage moves when contracts are recompeted, when agencies change mandates, and when carriers exit the market. You have to match the carrier to the exact injury date, not to the company in general.
Third-party administrators muddy the picture further. The name on the denial letter is frequently an administrator, not the underwriter. Confusing the two wastes discovery. Avoiding that trap is one of the most common carrier-identification mistakes attorneys make, and it is fixable before you draft a single request.
This is where a focused investigation pays for itself. Public legal sources carry the answers if you know where to look. OALJ and Benefits Review Board decisions name the employer and the carrier in the caption. Federal contract records show who held the work and where. FOIA coverage filings can show an employer, a carrier, and a policy date together.
ClaimTrove pulls those threads into one place. It maps employer aliases, surfaces the carriers that appear with a given contractor across thousands of records, and ties the pattern to injury dates. Run a ClaimTrove investigation on your employer before you draft discovery, and your interrogatories can name the carrier instead of asking who it is.
Keep the public and private lines clear. The method is teachable. The specific carrier that insured a specific employer on a specific date is exactly what your investigation has to establish, through the data first and then through discovery. Nail the DBA discovery mechanics of interrogatories, requests for production, and depositions before the OALJ, and you control the record the judge will weigh.
How Should You Sequence DBA Discovery for the Best Result?
Sequence turns good tools into a winning record. Run your investigation first, before the judge's initial notice opens discovery. Identify the employer's aliases, the probable carrier, and the decisions that already name them.
Then serve written discovery in a deliberate order. Lead with interrogatories and requests for production to force identity and documents into the open. Follow with requests for admission to lock down what the answers concede.
Depose last, once you hold the policy and the claim file. A deposition built on documents is far harder to evade than one built on hope. Reserve subpoenas and Section 18.57 sanctions for the parties that refuse to cooperate.
Respect the deadlines while you do it. Discovery does not pause your client's notice and filing clocks under the Longshore framework the DBA incorporates. Move with intent.
Strong DBA discovery mechanics start with knowing your target. When you can name the carrier, the employer entity, and the controlling decisions before you draft a single interrogatory, every request lands. Run your employer through ClaimTrove to pull the carrier, employer, and decision data fast, then turn that intelligence into discovery the other side cannot dodge.
