A litigation department is the group inside a law firm or a company that handles lawsuits, from the first demand letter through trial, appeal, and collection of a judgment. It coordinates the lawyers, paralegals, and specialists who move a case through its procedural stages, and it carries responsibility for the strategic decisions that shape how a dispute is fought or resolved. Whether the department serves many outside clients or a single corporate parent, its work is adversarial, deadline-driven, and governed by rules that control everything from how evidence is exchanged to when a notice of appeal must be filed.
Litigation sits opposite transactional practice. Transactional lawyers negotiate deals and draft the contracts; litigators handle what happens when those arrangements break down.
What Kinds of Cases the Department Handles
The everyday caseload runs across commercial disputes: breach of contract, intellectual property infringement, business torts such as fraud or interference with a competitor’s contracts, and challenges to government regulatory decisions. Employment disputes, product liability claims, and insurance coverage fights land in the same department.
Two categories reshape how the department staffs, budgets, and manages risk. Class actions let one or a few named plaintiffs represent a larger group that shares legal questions. Federal courts require four things before certifying a class: the group is too numerous for individual joinder, members share common questions of law or fact, the named plaintiffs’ claims are typical of the group, and the representatives will adequately protect the class’s interests.1Legal Information Institute. Federal Rules of Civil Procedure Rule 23 – Class Actions A class action can convert a modest individual claim into a case worth hundreds of millions, which changes everything about how the department resources it.
Multidistrict litigation operates on a different principle. When similar lawsuits are filed in courts around the country, a judicial panel can consolidate them before a single judge for pretrial proceedings, provided the cases share common factual questions and consolidation serves convenience and efficiency.2Office of the Law Revision Counsel. 28 U.S. Code 1407 – Multidistrict Litigation Pharmaceutical injury cases, data breach lawsuits, and product defect claims commonly travel this route. An MDL can occupy a department’s resources for years and requires coordination with dozens of other firms.
Who Works in a Litigation Department
Litigation departments are built as hierarchies that leverage experience at each level. Junior associates handle the foundational work: legal research, drafting motions, document review, and the logistics of running a case under close supervision. Senior associates run depositions, argue routine motions, manage direct client contact, and oversee the junior lawyers working on their matters.
Partners or shareholders sit at the top. They own the client relationships, set the strategic direction, and handle the highest-stakes courtroom work, especially at trial. In a law firm, they also carry financial responsibility for the department, which means originating business and maintaining profitability.
Support staff keep the operation functioning. Paralegals are often the most organized people in the building. They manage case files, draft routine filings, summarize deposition transcripts, and assemble trial exhibits; in a complex case, the paralegal frequently knows the document universe better than any lawyer on the team. Legal assistants handle calendaring, court filings, and correspondence. Larger departments add dedicated e-discovery analysts who manage the technical side of processing and reviewing electronic documents, a role that has grown as cases have become more data-heavy.
How a Case Moves Through the Department
Pre-Suit Evaluation
Before anything is filed, the department evaluates whether the case is worth pursuing or defending. That means interviewing witnesses, pulling preliminary documents, researching the governing law, and estimating both potential recovery and the cost of getting there. A realistic cost-benefit analysis at this stage keeps clients from pouring money into cases that look appealing on the surface and fall apart on examination. The decision to file or walk away often matters more than anything that happens later in the courtroom.
Pleadings
Formal litigation starts with pleadings. The plaintiff files a complaint stating the factual allegations and legal claims. The defendant answers, admitting or denying each allegation and raising any affirmative defenses, and may add counterclaims against the plaintiff or cross-claims against co-defendants. Any allegation not properly denied is treated as admitted, so even this early paperwork rewards careful attention.
Scheduling and Initial Disclosures
The court imposes a scheduling order early in the case, setting deadlines for adding parties, amending pleadings, completing discovery, and filing motions.3Legal Information Institute. Federal Rules of Civil Procedure Rule 16 – Pretrial Conferences, Scheduling, Management Once in place, changing the schedule requires good cause, not just agreement between the lawyers. Blown deadlines are one of the leading causes of legal malpractice claims, which is why calendar management, mundane as it sounds, is treated seriously.
Before formal discovery requests go out, the parties must exchange initial disclosures without being asked. Each side identifies people with relevant information, provides supporting documents and electronically stored information, produces a damages computation with backup, and turns over any applicable insurance agreements. The parties also meet early to discuss evidence preservation, plan the scope of discovery, and submit a joint discovery plan to the court.4Legal Information Institute. Federal Rules of Civil Procedure Rule 26 – Duty to Disclose, General Provisions Governing Discovery
Discovery
Discovery is the most expensive and time-consuming phase of any lawsuit. Each side forces the other to hand over evidence, answer written questions, and produce witnesses for examination. The scope covers any nonprivileged information relevant to a party’s claims or defenses, but it must be proportional to the needs of the case, considering factors like the amount in controversy, the parties’ relative access to information, and whether the burden of producing material outweighs the likely benefit.4Legal Information Institute. Federal Rules of Civil Procedure Rule 26 – Duty to Disclose, General Provisions Governing Discovery
The main tools are:
- Interrogatories, written questions answered under oath, capped at 25 per side in federal court unless the court allows more.5Legal Information Institute. Federal Rules of Civil Procedure Rule 33 – Interrogatories to Parties
- Requests for production, formal demands for documents, electronically stored information, and tangible items, with the responding party given 30 days to produce the materials or state specific objections.6Legal Information Institute. Federal Rules of Civil Procedure Rule 34 – Producing Documents, Electronically Stored Information, and Tangible Things
- Depositions, live sworn testimony taken outside the courtroom, capped at 10 per side with each deposition limited to one day of seven hours. Depositions lock witnesses into statements they cannot easily change at trial and let the examining lawyer see how the witness handles pressure.7Legal Information Institute. Federal Rules of Civil Procedure Rule 30 – Depositions by Oral Examination
Electronic discovery drives most of the cost in modern cases. A single matter can involve millions of emails, text messages, database records, and chat messages. Managing that volume requires dedicated software, review teams, and protocols for collection, processing, and production.
Evidence Preservation
The duty to preserve relevant evidence begins the moment litigation is reasonably anticipated, not when a complaint is filed. Standard practice is to issue a litigation hold notice to everyone in the organization who might have relevant information, telling them to stop any routine deletion of documents, emails, and electronic files.
The consequences of getting this wrong are severe. Under the federal rules, when electronically stored information that should have been preserved is lost because a party failed to take reasonable steps, the court can order measures to cure the prejudice. If the court finds the loss was intentional, it can instruct the jury to presume the missing information was unfavorable, dismiss the case, or enter a default judgment against the destroying party.8Legal Information Institute. Federal Rules of Civil Procedure Rule 37 – Failure to Make Disclosures or to Cooperate in Discovery These sanctions can flip the outcome of a case regardless of the underlying merits.
Motions
Both sides file motions throughout the case. Some are procedural, like requesting more time or asking to compel the production of documents being withheld. Others are dispositive and seek to end part or all of the case before trial.
Two dispositive motions matter most. A motion to dismiss, filed early, argues that even if every factual allegation in the complaint were true, the plaintiff has not stated a valid legal claim. Federal Rule 12(b)(6) allows that challenge before any discovery happens, and defendants can also move to dismiss for lack of jurisdiction or improper venue.9Legal Information Institute. Federal Rules of Civil Procedure Rule 12 – Defenses and Objections, When and How Presented A motion for summary judgment, filed after discovery, argues that the evidence is so one-sided no reasonable jury could find for the opposing party; the court grants it when there is no genuine dispute of material fact and the moving party is entitled to judgment as a matter of law.10Legal Information Institute. Federal Rules of Civil Procedure Rule 56 – Summary Judgment A successful summary judgment motion ends the case without a trial.
Trial Preparation, Settlement, and ADR
Cases that survive dispositive motions move to trial preparation: assembling exhibits, drafting proposed jury instructions, preparing witnesses, and developing a narrative that will land with a jury or judge. Some departments run mock trials or focus groups to test themes before the real thing.
Most cases settle before reaching trial. Settlement talks continue throughout the case and intensify as trial approaches and the evidence becomes clearer. Many courts require mediation or another form of alternative dispute resolution before trial, and some disputes are routed to binding arbitration by contract. Federal Rule 68 adds a cost-shifting incentive: a defendant can serve a written offer of judgment, and if the plaintiff rejects it and ends up with a less favorable result at trial, the plaintiff must pay the costs incurred after the offer.11Legal Information Institute. Federal Rules of Civil Procedure Rule 68 – Offer of Judgment
Post-Trial and Enforcement
A verdict does not always end the matter. The losing side may file post-trial motions challenging the verdict or seeking a new trial. If those fail, the next step is appeal. In federal civil cases, the notice of appeal must be filed within 30 days after entry of judgment, extended to 60 days when the federal government is a party.12Legal Information Institute. Federal Rules of Appellate Procedure Rule 4 – Appeal as of Right, When Taken Missing that deadline almost always kills the right to appeal.
Winning a money judgment and collecting it are separate problems. The standard enforcement tool is a writ of execution, which directs a U.S. Marshal or equivalent officer to seize the debtor’s assets. The process generally follows the law of the state where the court sits, and the judgment creditor may have to post a bond and cover the marshal’s expenses upfront.13U.S. Marshals Service. Writ of Execution Discovery tools remain available to identify the debtor’s assets, bank accounts, and other property. In high-value commercial cases, enforcement can be as contentious as the trial.
Technology in the Work
Technology has reshaped how litigation departments operate, and e-discovery sits at the center of that change. When a case involves millions of documents, human review alone is neither practical nor affordable. Technology-assisted review uses software trained by human reviewers to classify documents as relevant, privileged, or non-responsive, reducing the volume lawyers must read individually.14EDRM. Technology Assisted Review Reviewers code a sample, the software learns the patterns and applies predictions to the full collection, and statistical sampling measures accuracy.
Beyond document review, case management platforms organize exhibits, track deadlines, manage deposition transcripts, and build case timelines. These tools let teams in multiple offices work on the same case file and keep nothing from falling through the cracks in a process governed by dozens of overlapping deadlines.
In-House Versus Law Firm Departments
A litigation department looks fundamentally different depending on whether it sits inside a law firm or inside a corporation. Law firm departments serve multiple outside clients, run on billable-hour economics, and measure success by case outcomes and revenue. A partner’s standing is tied directly to the business they generate and the results they deliver.
An in-house litigation department serves one client: the company itself. It operates as a cost center, not a profit center. The mission is managing the company’s overall legal risk and keeping litigation spending in check. In-house counsel spend much of their time selecting and overseeing outside firms, making sure strategy aligns with business goals rather than running up hours. They handle internal investigations, monitor regulatory compliance, and manage the administrative infrastructure of ongoing lawsuits. In-house teams rarely act as lead trial counsel, but they increasingly rely on standardized billing codes like the Uniform Task-Based Management System to track outside firm spending and press for efficiency.
The tension between the two models is real. Outside counsel may prefer an aggressive strategy that maximizes billable engagement. In-house counsel may push for early settlement that costs less overall, even if it leaves money on the table. The relationships that work best acknowledge that dynamic openly and manage it through clear communication about goals, budgets, and risk tolerance from the start.
