Understanding Discovery and eDiscovery in U.S. Litigation

Good Pine P.C.  |  Litigation  |  New York & New Jersey  |  A Guide for Korean Companies Doing Business in the United States

For companies accustomed to litigation in Korea or other civil-law jurisdictions, U.S. discovery is one of the most disorienting aspects of American civil procedure. The scope is broad, the obligations are affirmative, and the consequences of mishandling it — financially, reputationally, and legally — can be severe. Discovery is not a preliminary formality; it is often where U.S. litigation is decided, long before any trial begins.

This article explains how discovery works in U.S. civil litigation, what the rise of electronically stored information has added to that process, and what Korean companies operating in the United States should understand before a dispute arises.

What Discovery Is — and Why It Is Different

In U.S. civil litigation, discovery is the formal pre-trial process through which each party obtains evidence from the other. It is governed by the Federal Rules of Civil Procedure in federal court and by analogous rules in New York and New Jersey state courts. The defining characteristic of U.S. discovery — and the one that most surprises foreign companies — is that it is broad and affirmative. Each party is required to disclose not only the information that supports its own position, but also materials that may be unfavorable or damaging to it.

This stands in sharp contrast to Korean civil procedure, where evidentiary exchange is far more limited and court-directed. In the United States, the parties themselves drive the discovery process, subject to judicial oversight. The underlying premise is that disputes should be resolved on the full factual record — not on the basis of superior information control by one side. That premise produces a system that is more transparent, more expensive, and more demanding of advance preparation than most foreign companies expect.

The Main Tools of Discovery

Document Requests

A request for production of documents is a written demand that the opposing party produce specified categories of records — contracts, emails, invoices, financial statements, internal reports, board minutes, communications with regulators, and anything else reasonably likely to contain relevant information. The scope is deliberately broad: under the Federal Rules, discovery extends to any matter that is relevant to a claim or defense and proportional to the needs of the case. What is proportional depends on the amount in controversy, the importance of the issues, and the relative access each party has to the information.

For a company with years of business records, sprawling email archives, and data stored across multiple systems and jurisdictions, a document request can generate hundreds of thousands of responsive pages. The volume is not unusual. Managing it efficiently is an organizational and legal challenge that begins well before any lawsuit is filed.

Interrogatories

Interrogatories are written questions that must be answered in writing, under oath, within a specified time period. They are typically used to identify witnesses, clarify the other side's factual positions, establish the chain of custody for important documents, and pin down key facts that will be developed further in depositions. Answers to interrogatories are signed under oath and can be used at trial — inconsistencies between interrogatory answers and later testimony are a standard impeachment tool.

Depositions

A deposition is a sworn, in-person or virtual examination of a witness conducted by opposing counsel, transcribed verbatim by a court reporter and often recorded on video. Any witness with relevant knowledge can be deposed — employees, executives, third-party contractors, and expert witnesses alike. Deposition testimony can be used at trial to impeach a witness who testifies inconsistently, or as direct evidence if the witness is unavailable.

For Korean companies, depositions present particular challenges. Witnesses must testify in a format and at a level of directness that may feel unfamiliar. Translators can be used, but accuracy and composure under extended cross-examination are critical. Even minor inconsistencies — between a witness's deposition testimony and a prior email, or between what the witness says and what a colleague has already testified — can be exploited effectively at trial. Preparation is not optional; it is essential.

Practical tip: U.S. deposition preparation typically involves multiple sessions with counsel reviewing documents, practicing difficult questions, and understanding the expected tone and pace of testimony. Witnesses who are unprepared for the format — not just the facts — are at a significant disadvantage.

The Rise of eDiscovery: Digital Evidence in Every Case

Modern U.S. litigation is driven by electronically stored information, universally referred to as ESI. Emails, text messages, Slack and Teams communications, shared-drive files, cloud storage, database records, and the metadata embedded in all of these — every category of digital information is treated as potentially discoverable evidence, subject to the same obligations as paper documents. In most commercial disputes, ESI constitutes the overwhelming majority of the evidence.

eDiscovery refers to the full lifecycle of managing ESI in litigation: identifying where relevant data exists, preserving it from deletion or alteration, collecting it in a forensically sound manner, processing and reviewing it for relevance and privilege, and producing it to the opposing party. Each stage has its own technical requirements, legal standards, and cost implications. The process is governed by the Federal Rules of Civil Procedure — particularly Rule 26, which governs the scope of discovery and the parties' obligations regarding ESI — as well as by case-specific court orders.

The Duty to Preserve and the Litigation Hold

The most important eDiscovery obligation — and the one with the most severe consequences if ignored — is the duty to preserve. Once a company reasonably anticipates litigation, it is legally required to suspend routine document-deletion policies, halt automatic data purges, and take affirmative steps to ensure that potentially relevant ESI is retained. This obligation is triggered not by the filing of a lawsuit, but by the earlier moment when litigation becomes reasonably foreseeable — which may be as early as receiving a demand letter, a government subpoena, or a written notice of a claim.

The mechanism for satisfying this duty is the litigation hold: a formal written directive, issued to employees and IT personnel, instructing them to preserve all potentially relevant documents and data. A well-drafted litigation hold identifies the subject matter of the anticipated dispute, specifies the categories of documents and data that must be preserved, identifies the custodians — employees likely to have relevant information — and directs IT to suspend any automated deletion or overwriting of relevant systems. The hold must be monitored and updated as the case develops and new custodians or data sources become relevant.

Failure to implement a timely and effective litigation hold is one of the most common — and most costly — mistakes in U.S. litigation. Courts treat the deliberate or negligent destruction of relevant evidence as spoliation, and the sanctions available for spoliation are substantial: adverse-inference jury instructions (telling the jury it may assume the destroyed evidence was unfavorable), monetary sanctions, dismissal of claims or defenses, and in egregious cases, default judgment. The reputational damage to a company found to have destroyed evidence can outlast the litigation itself.

Practical tip: The litigation hold should be issued the moment a dispute becomes reasonably foreseeable — not when a lawsuit is actually filed. The gap between those two events is where most preservation failures occur.

Special Considerations for Korean Companies

Korean corporations face a distinct set of challenges when drawn into U.S. litigation, most of which stem from the collision between U.S. discovery's expansive reach and the organizational, legal, and cultural realities of Korean business operations.

Data Location Does Not Shield Disclosure

A common misconception is that documents stored on servers in Korea, or held by Korean employees at Korean headquarters, are beyond the reach of U.S. courts. They are not. U.S. courts have consistently held that a party subject to U.S. jurisdiction — including a U.S. subsidiary of a Korean parent — can be compelled to produce documents that are within its possession, custody, or control, regardless of where those documents are physically located or who within the corporate family holds them. Control, in this context, is a legal concept: if the U.S. entity has the legal right or practical ability to obtain documents from its Korean parent, those documents are subject to production.

This means that Korean companies with U.S. subsidiaries or operations cannot treat their Korean document systems as insulated from U.S. discovery. Early mapping of where relevant data resides — across both the U.S. entity and affiliated Korean entities — is essential to understanding the company's exposure and building a defensible discovery response.

Korean Privacy Law and Cross-Border Data Transfers

Korea's Personal Information Protection Act (PIPA) restricts the export of personal data outside Korea, creating a genuine tension with U.S. discovery obligations. When a U.S. court orders production of documents that contain personal information subject to PIPA — employee records, customer data, personnel communications — the producing party faces potentially conflicting legal obligations under two different legal systems.

This tension is manageable but requires careful advance planning. Experienced counsel can seek protective orders that limit the use and dissemination of produced data, anonymize personal information where permissible, and structure the production to minimize PIPA exposure while satisfying U.S. court requirements. The key is identifying the conflict early — before a production deadline creates a crisis — and raising it with the court proactively. Courts generally respond more favorably to parties who identify legal constraints in advance and propose workable solutions than to those who cite foreign privacy law as a reason for noncompliance after the fact.

Language, Translation, and Document Review

Korean-language emails, reports, and internal communications are fully subject to U.S. discovery and must be reviewed, translated as necessary, and produced in a form that opposing counsel and the court can use. The translation burden in a case involving substantial Korean-language ESI can be significant — both in cost and in the time required to produce accurate translations of technical, legal, or industry-specific content.

Managing this effectively requires bilingual document reviewers who understand both the legal standards for relevance and privilege under U.S. law and the business and cultural context in which Korean communications are written. Korean business communications frequently contain nuance, formality conventions, and implicit references that require contextual understanding — not just word-for-word translation — to assess their evidentiary significance accurately.

Coordination Between Korean Headquarters and U.S. Counsel

One of the most common sources of discovery problems for Korean companies is a failure of internal coordination. The U.S. legal team may not know what documents exist at Korean headquarters. Korean headquarters may not understand the scope or urgency of U.S. discovery obligations. Decisions about what to preserve, what to produce, and what to withhold on privilege grounds may be made inconsistently across the two entities.

Early and sustained communication between Korean headquarters and U.S. outside counsel — structured around a clear understanding of who is responsible for what — is essential to avoid these problems. A single coordinating attorney or bilingual project manager who understands both the legal requirements and the organizational structure of the Korean parent can make a significant difference in the efficiency and quality of the discovery response.

Practical tip: Before U.S. litigation begins, Korean companies should map where their relevant data resides, identify key Korean-side custodians, and establish a protocol for coordinating between Korean headquarters and U.S. counsel. Building this infrastructure reactively — after a lawsuit is filed — is expensive and error-prone.

Managing the Cost and Risk of Discovery

Discovery is frequently the single largest expense in U.S. commercial litigation. Attorney review of documents — assessing each one for relevance, privilege, and responsiveness — is labor-intensive and costly, and in large cases the volume of ESI can make the review burden feel unmanageable. It is not, however, uncontrollable. The companies that manage discovery costs most effectively are those that invest in preparation before any dispute arises.

A centralized, well-maintained document-retention policy — one that systematically preserves documents the company needs and disposes of those it does not, on a regular schedule — dramatically reduces the volume of data that must be reviewed when litigation arises. Keyword filters, technology-assisted review, and analytics tools can further narrow large datasets to the most likely sources of responsive documents. Engaging experienced eDiscovery vendors early in the process, rather than scrambling to find resources after a production deadline has been set, gives the legal team time to design an efficient workflow rather than an expensive one.

Beyond cost, the manner in which a party conducts discovery sends signals to the court and to opposing counsel about the party's credibility and professionalism. A disciplined, transparent, and well-organized discovery response demonstrates good faith. Courts notice — and draw inferences from — the difference between a party that takes its discovery obligations seriously and one that does not.


Discovery Sanctions: What Is at Stake

The consequences of discovery misconduct in U.S. courts range from monetary sanctions to case-dispositive remedies. Rule 37 of the Federal Rules of Civil Procedure and its state-court analogs give courts broad authority to sanction parties for failing to comply with discovery obligations — including failing to preserve ESI, failing to produce responsive documents, making untimely productions, and providing false or misleading interrogatory answers.

The most significant sanction available is the adverse-inference instruction: a direction to the jury that it may presume the destroyed or withheld evidence was unfavorable to the party responsible for its loss. In a closely contested case, an adverse-inference instruction can be outcome-determinative. Courts have also awarded substantial monetary sanctions, struck pleadings, and in the most egregious cases entered default judgment against parties who engaged in systematic discovery abuse. For Korean companies doing business in the United States, where reputation and ongoing commercial relationships are at stake, the reputational consequences of a finding of discovery misconduct can extend well beyond the litigation itself.
