What Is Discovery? A Plain-English Guide to One of the Most Important Phases of a Lawsuit

By Jade Lyons

When people think about lawsuits, they often picture dramatic courtroom scenes, surprise witnesses, and a judge making a final ruling. In reality, much of a civil lawsuit happens long before anyone steps into a courtroom. One of the most significant, and often longest, stages of litigation is known as discovery.

Whether you’re a business owner involved in a contract dispute or an individual navigating a civil lawsuit, understanding the discovery process can help you better prepare for what lies ahead. While every case is unique, discovery serves an important purpose: allowing each side to gather relevant information before trial.

Discovery is the formal process through which parties to a lawsuit exchange information and evidence related to the claims and defenses in a case. Rather than relying on surprises in court, the legal system encourages transparency by requiring each side to disclose relevant information that may help resolve the dispute.

The goal of discovery is to ensure that both parties have access to the facts needed to evaluate their positions, prepare their arguments, and, in many cases, determine whether the dispute can be resolved before trial.

Depending on the complexity of the case, discovery may last several months, or even longer in more involved litigation.

Discovery is often one of the most important phases of a lawsuit because it helps establish the facts surrounding the dispute. Documents, communications, financial records, photographs, and witness testimony gathered during discovery frequently shape the direction of a case.

In many instances, information uncovered during discovery may clarify misunderstandings, reveal strengths or weaknesses in a party’s position, or provide the foundation for meaningful settlement discussions. While some cases ultimately proceed to trial, many are resolved after discovery provides a clearer picture of the facts.

Although the discovery process can vary depending on the circumstances of a case, several tools are commonly used in civil litigation.

Interrogatories are written questions that one party sends to another. The receiving party is generally required to provide written responses under oath within the time allowed by the applicable rules or court order.

These questions often seek basic factual information, including:

  • The identities of individuals with knowledge of the dispute
  • A timeline of relevant events
  • The factual basis for certain claims or defenses
  • Information about damages being sought

Because responses are made under oath, accuracy and completeness are important.

Requests for Production ask a party to provide documents or electronically stored information relevant to the case.

Examples may include:

  • Contracts and agreements
  • Emails
  • Text messages
  • Invoices
  • Financial records
  • Photographs or videos
  • Business records
  • Internal communications

As more business communications occur electronically, digital evidence has become an increasingly important part of civil litigation. Emails, cloud-stored files, collaboration platforms, and text messages may all become relevant depending on the issues involved in a case.

A Request for Admission asks another party to admit or deny certain facts.

These requests are designed to narrow the issues that remain in dispute. For example, a party may be asked to admit the authenticity of a document or acknowledge that a particular event occurred on a specific date.

By identifying facts that are not genuinely contested, Requests for Admission can help streamline the litigation process.

Depositions are often one of the most recognizable forms of discovery.

During a deposition, a witness or party answers questions under oath before trial. Attorneys for the parties have the opportunity to ask questions, and a court reporter creates an official transcript of the testimony.

Depositions allow attorneys to better understand what witnesses know, evaluate testimony, and preserve statements that may later become relevant in court.

While many people feel anxious about giving a deposition, preparation and understanding the process can help alleviate some uncertainty.

Technology has changed the way businesses and individuals communicate, and modern litigation has evolved alongside it.

Today, discovery frequently involves electronically stored information (ESI), sometimes referred to as electronic discovery or eDiscovery. This may include:

  • Emails
  • Text messages
  • Cloud-based documents
  • Instant messaging platforms
  • Electronic calendars
  • Digital photographs
  • Metadata
  • Business collaboration tools

Because electronic information exists in many different locations and formats, preserving potentially relevant data can become an important consideration once litigation is anticipated or underway.

One common misconception is that deleting emails, text messages, or documents after a dispute arises will make them disappear from the case.

In reality, parties to litigation may have obligations to preserve potentially relevant evidence. Destroying or failing to preserve evidence after litigation is reasonably anticipated can create additional legal issues and may affect how a court views the case.

For businesses, having organized recordkeeping practices and document retention policies can help simplify this process and reduce unnecessary complications.

Not necessarily.

Although discovery is a critical step in preparing for trial, many civil disputes are resolved before a judge or jury hears the case. As information is exchanged, the parties often gain a better understanding of the strengths and weaknesses of their respective positions.

This increased understanding may create opportunities for negotiation, mediation, or other forms of dispute resolution.

Of course, every case is different, and some disputes do proceed to trial. Discovery simply helps ensure that each side has the information necessary to prepare its case.

If you or your business becomes involved in litigation, organization can make a meaningful difference.

Maintaining clear business records, preserving relevant communications, and responding thoughtfully to discovery requests can help the process move more efficiently. It’s also important to avoid deleting or altering potentially relevant information once litigation is anticipated. Because discovery often involves legal deadlines and procedural requirements, working closely with your attorney can help you prepare timely and appropriate responses.


For many people, discovery is one of the least understood aspects of civil litigation, but it is also one of the most important. Through written questions, document exchanges, depositions, and other discovery tools, the parties work to uncover the facts necessary to move the case forward.

While the process may seem complex, understanding its purpose can help reduce uncertainty and provide a clearer picture of what to expect during a lawsuit. If your business is involved in a civil dispute or you have questions about the litigation process, consulting with an attorney can help you understand your rights, responsibilities, and the procedural steps that may apply to your specific circumstances.
