Clients often think the decisive moment in a business lawsuit is a cross-examination, a motion argument, or a dramatic ruling from the bench. In reality, many commercial cases are shaped much earlier. The cases that are prosecuted well usually begin with disciplined presuit work: preserving evidence before it disappears, identifying the right witnesses and data sources, and giving counsel the documents needed to plead claims, prove damages, and control the narrative. In federal court, discovery reaches nonprivileged matter that is relevant to a claim or defense and proportional to the needs of the case, and parties must identify likely witnesses, supporting documents or ESI, and a damages computation without waiting for formal discovery requests. (U.S. Code)
That reality is especially clear in recent Southern District of New York litigation. In recent SDNY cases, plaintiffs who obtained meaningful early relief did not get there by filing a complaint and hoping for the best. They built records quickly through expedited discovery, targeted motions to compel, expert analysis, third-party evidence, and careful witness preparation.
What clients should do before the complaint is filed
The first job is preservation. Once litigation is reasonably foreseeable, the duty to preserve relevant information matters. Rule 37(e)’s advisory material explains that a preservation obligation can arise when litigation is reasonably foreseeable, and that when electronically stored information is lost because a party failed to take reasonable steps to preserve it, courts focus first on whether it can be restored or replaced; the rule requires reasonable steps, not perfection. In practical terms, that means you should stop auto-delete settings, preserve relevant emails and texts, secure cloud folders, and make sure key employees do not “clean up” their files. (U.S. Code)
The second job is to map where the evidence actually lives. In a modern commercial dispute, the case file is rarely limited to a signed contract and a few emails. Relevant information may sit in email, text messages, shared drives, CRM systems, accounting software, board decks, spreadsheets, pricing models, call logs, cloud folders, and on personal devices used for business. Rule 34 expressly reaches documents, electronically stored information, and tangible things stored in any medium, and recent SDNY cases show that off-email communications and internal data sources can become central evidence. In Palantir Technologies, Inc. v. Jain, the court relied on recruiting texts and LinkedIn-related communications; in Marsh USA LLC v. Parrish, the court pointed to evidence involving pricing models, renewal timelines, growth strategies, compensation data, and confidential client information placed into a SharePoint site. (U.S. Code)
The third job is to build a usable chronology and witness map. Your lawyer needs more than a stack of documents. Counsel needs to know who said what, when the dispute began, what changed, who approved the relevant decisions, where the money moved, and who can explain the business context. Federal Rule 26 requires early disclosure of individuals likely to have discoverable information and the documents or ESI a party may use to support its claims or defenses. It also requires a computation of each category of damages claimed and the materials on which that computation is based. A client who can help organize the timeline, identify custodians, and gather the financial proof of loss is not doing the lawyer’s job; that client is making the case provable. (U.S. Code)
The fourth job is honesty. Your lawyer does not need a sanitized story. Your lawyer needs the real one. If there is a bad email, a contradictory text, a delay in performance, a weak witness, or a document that cuts the other way, that fact needs to be surfaced early. Discovery rewards realism and punishes surprise. A sophisticated litigation strategy usually depends on confronting the hard facts before the other side weaponizes them.
What can actually be discovered in discovery?
The short answer is: a great deal. Discovery is not unlimited, but it is broad. It begins with mandatory initial disclosures. Before traditional document requests even begin, parties generally must identify likely witnesses, disclose the documents or ESI they may use to support their claims or defenses, and provide a damages computation with supporting material. That is one reason why plaintiffs who prepare early are often better positioned than plaintiffs who file first and organize later. (U.S. Code)
Discovery then expands into formal tools. A party can request production of documents, ESI, and tangible things, and can even seek entry onto land or property to inspect, photograph, test, survey, or sample relevant items or operations. Depositions allow counsel to question witnesses under oath, and a notice to a party deponent can be paired with a Rule 34 request requiring the witness to bring documents to the deposition. In the right case, that means discovery can reach contracts, amendments, emails, texts, spreadsheets, databases, call recordings, images, physical objects, internal reports, pricing models, and site inspections. (U.S. Code)
Parties can also serve interrogatories, which must generally be answered separately and fully in writing under oath, and requests for admission, which can force the other side to admit facts, the application of law to fact, opinions, or the genuineness of documents. Those tools matter because they narrow issues, pin down positions, and create a record that can be used on motion practice or at trial. In many business cases, they are also invaluable for identifying decision-makers, clarifying damages theories, and forcing the other side to commit to a version of events. (U.S. Code)
Third-party discovery is often just as important as party discovery. Rule 45 subpoenas can require nonparties to testify, produce documents or ESI, or permit inspection of premises. In commercial litigation, that can mean customers, vendors, lenders, accountants, consultants, former employees, competitors, or market participants. When your case depends on how a market works, how funds moved, what a customer was told, or what a third party observed, subpoena practice can be decisive. (U.S. Code)
Experts are part of discovery too. Rule 26 permits deposition of a testifying expert after the report is served, while also protecting drafts of reports and many attorney-expert communications. In a sophisticated commercial case, damages, valuation, lost profits, market structure, industry custom, technical performance, or accounting issues may all require expert proof. That is why clients who can produce clean business data early give their lawyers a real advantage. (U.S. Code)
Not everything is discoverable. Attorney-client privilege still matters. Work product still matters. Rule 26 protects documents prepared in anticipation of litigation unless the demanding party makes a special showing, and even then courts must protect counsel’s mental impressions, conclusions, and legal theories. Courts can also enter protective orders to guard trade secrets and confidential commercial information. In other words, “confidential” is not a magic word that blocks discovery, but confidential business information is often produced under controlled procedures rather than withheld outright. (U.S. Code)
Discovery also has teeth. A party may move to compel disclosure or discovery. If a party fails to disclose required information or identify a witness, that information or witness may be excluded from use on a motion, at a hearing, or at trial unless the failure was substantially justified or harmless. And when a party disobeys discovery orders, Rule 37 authorizes sanctions that can include deeming facts established, barring claims or defenses, striking pleadings, or worse. Discovery is not a side show; it is where allegations become evidence and where sloppiness becomes risk. (U.S. Code)
Recent SDNY cases show why preparation and discovery matter
One recent SDNY case that drew national attention was FuboTV, Inc. v. The Walt Disney Company, the litigation over the proposed Venu Sports joint venture. Judge Garnett’s opinion notes that, after “a period of intense but expedited discovery,” the court held a five-day evidentiary hearing in August 2024. That alone tells clients something important: when the stakes are high enough, courts can move fast, and plaintiffs seeking early relief need to be ready with evidence almost immediately.
What made Fubo especially instructive was not just the injunction itself, but the discovery fight that built the record. The court described motions to compel production of intra-defendant communications that had been withheld or redacted under a claimed common-interest privilege, and it granted Fubo’s motion to compel those communications. The court also granted Fubo’s motion to obtain unredacted responsive documents from Fox and entered an amended stipulated protective order with heightened confidentiality designations to facilitate discovery. Even third-party discovery was litigated. That is what effective commercial litigation often looks like in practice: not passive waiting, but targeted pressure on the real documents, the real communications, and the real decision-makers.
That work mattered. Judge Garnett found that, on the record before the court, “the evidence is overwhelming” that at least one aspect of the proposed joint venture would tend to produce anticompetitive effects in a relevant market, and held that Fubo was likely to succeed on the merits of its Clayton Act claim. The injunction then reshaped the case’s leverage. The Justice Department and 16 states later backed the injunction on appeal, and in January 2025 Disney agreed to combine Hulu + Live TV with Fubo; Reuters reported that Fubo agreed to drop the Venu litigation and would receive a $220 million settlement, and Venu was later discontinued. The lesson for clients is straightforward: early, disciplined discovery can change the economics of a case long before trial.
Another strong example is Cumulus Media New Holdings Inc. v. The Nielsen Company (US) LLC. The court noted that Cumulus filed both its complaint and its preliminary-injunction motion on October 16, 2025, obtained partial expedited discovery on October 29, and then presented an evidentiary hearing in December 2025 featuring economics experts, company executives, and executives from other broadcasting companies. In January 2026, the court held that Cumulus had shown a strong showing of irreparable harm and a substantial likelihood of success on the merits. The practical takeaway is that when a business case depends on market structure, pricing power, or competitive harm, clients need to help counsel line up data, experts, and third-party support early. (Justia)
Marsh USA LLC v. Parrish is equally instructive in a different kind of business fight. There, the court granted Marsh’s request for a preliminary injunction in part, including relief against solicitation of employees and clients and against use or disclosure of confidential information. Why? Because Marsh did not rely on abstract accusations. It pointed to declarations showing alleged misuse of pricing models, renewal timelines, growth strategies, and detailed employee compensation and benefits, as well as evidence that confidential client information had been placed into a newly created SharePoint site for later use. In restrictive covenant, fiduciary duty, trade secret, and unfair competition cases, contemporaneous business records often matter more than broad rhetoric. (Justia)
Then there is Palantir Technologies, Inc. v. Jain, another recent SDNY case that illustrates a lesson many clients underestimate: off-channel communications are still evidence. In granting preliminary-injunction relief in part, the court pointed to messages in which one defendant urged another to consider joining a new venture, acknowledged he had gone into “sell mode,” and discussed Palantir employees using LinkedIn profiles and recruitment strategies, including the idea that they “could 100% poach” at least one employee. For clients, the message is simple: if a dispute touches texts, LinkedIn, direct messages, or personal-device communications used for business purposes, your lawyer needs to know that immediately. (Justia)
What this means for clients in real life
If you are thinking about bringing a lawsuit, do not wait for formal discovery to start acting like a litigant. Preserve first. Organize second. Tell your lawyer where the facts live. Put together the contract story and the money story. Identify the people who made the decisions, the people who received the communications, and the people who can explain what happened. The earlier your lawyer can see the full record, the better your lawyer can decide what claims to file, what relief to seek, and what discovery to pursue first.
As a practical matter, clients are most helpful when they do five things well: preserve the evidence, identify all relevant custodians and data sources, gather the core business documents, help quantify damages, and disclose the bad facts early. Clients become least helpful when they self-edit, forward documents around carelessly, delete messages, or assume that side-channel communications will stay hidden.
The strongest plaintiffs also understand that discovery is not a burden to endure; it is a tool to use. Good discovery can force the other side to commit to positions, produce the documents they hoped would stay buried, hand over third-party evidence, expose inconsistencies, and create a hearing or trial record that changes settlement leverage. That is exactly what happened in the recent SDNY matters above.
How Desai, Raveica, Raveica & Arshad, P.C. helps clients succeed
At Desai, Raveica, Raveica & Arshad, P.C., commercial litigation is approached with that reality in mind. A strong case is not built by filing first and figuring it out later. It is built by identifying the claims that matter, preserving the evidence before it disappears, organizing the facts into a usable record, and pursuing the discovery that will actually move the case.
For clients, that means the firm’s litigation team can help you make the right moves at the right time: issue preservation guidance early, identify key custodians and data sources, structure the complaint around proof rather than speculation, develop damages support, and push targeted discovery that exposes the documents, communications, and testimony that matter most. In business and commercial litigation, shareholder disputes, fraud cases, financing disputes, and other high-stakes matters, that kind of disciplined preparation is often the difference between a lawsuit that drifts and a lawsuit that puts real pressure on the other side.
When a client comes prepared—and when counsel knows how to turn preparation into discovery leverage—the case gets stronger at every stage: before filing, during motion practice, through document discovery and depositions, at injunction hearings, in settlement negotiations, and, if necessary, at trial. That is the kind of aggressive, organized, evidence-driven representation Desai, Raveica, Raveica & Arshad, P.C. aims to deliver.
