Discovery

The short version

Discovery is the process where parties in a lawsuit exchange information and evidence with each other before trial. This helps everyone understand the facts, strengths, and weaknesses of each side's case. It's important because it prevents surprises at trial and often helps parties settle the case without going to court.

The law this is built on

Every point below comes from the authority named next to it. Verify the current text before relying on it.

Fed. R. Civ. P. 26(b)(1)
This rule states that parties can discover any nonprivileged matter that is relevant to any party's claim or defense and proportional to the needs of the case.
Why it matters: This means you can ask for almost any information that could help prove or disprove a claim, as long as it's not a secret (privileged) and is reasonably necessary.
Fed. R. Civ. P. 26(a)(1)
This rule requires parties to automatically provide certain basic information to each other early in the case, without waiting for a request.
Why it matters: You don't have to ask for some crucial initial evidence; the other side must provide it automatically, and you must do the same.
Fed. R. Civ. P. 30, 33, 34, 36
These rules outline the main types of discovery tools: depositions (Rule 30), interrogatories (Rule 33), requests for production of documents (Rule 34), and requests for admission (Rule 36).
Why it matters: These rules give you the specific ways you can formally ask for information, testimony, documents, or admissions from the other side.
Fed. R. Civ. P. 37
This rule describes what happens if a party fails to cooperate in discovery or does not provide requested information.
Why it matters: If the other side won't follow the discovery rules, this rule allows you to ask the court to order them to comply or face penalties.

Words you need to know

Discovery: The formal process of exchanging information, evidence, and witness lists between parties in a lawsuit before trial, as outlined in Fed. R. Civ. P. 26-37.
Initial Disclosures: Information that parties must automatically provide to each other early in a case, including witnesses, documents, damages calculations, and insurance agreements (Fed. R. Civ. P. 26(a)(1)).
Interrogatories: Written questions sent from one party to another, which the receiving party must answer in writing and under oath (Fed. R. Civ. P. 33).
Requests for Production: Formal requests to another party to provide documents, electronically stored information (ESI), or other tangible items for inspection and copying (Fed. R. Civ. P. 34).
Depositions: Out-of-court sworn testimony of a witness, taken down by a court reporter, usually with lawyers asking questions (Fed. R. Civ. P. 30).
Requests for Admission: Written statements sent to another party asking them to admit or deny certain facts or the authenticity of documents (Fed. R. Civ. P. 36).
Privilege: A legal right that allows a party to refuse to disclose certain information, such as communications between an attorney and client (attorney-client privilege) or doctors and patients.

How the process actually works

1
Meet and Confer (Planning)
At least 21 days before a scheduling conference is held or a scheduling order is due.
The parties must meet to discuss their case, how they will handle discovery, and develop a proposed discovery plan (Fed. R. Civ. P. 26(f)). They must submit this plan to the court.
2
Initial Disclosures
Within 14 days after the Rule 26(f) conference, unless otherwise ordered or stipulated.
Each party automatically provides certain basic information without waiting for a request from the other side. This includes contact information for witnesses, copies of relevant documents, damages calculations, and insurance information (Fed. R. Civ. P. 26(a)(1)).
3
Formal Discovery Requests
After initial disclosures, and typically ending by a court-set deadline (the 'discovery cutoff').
Parties send formal requests to each other, such as interrogatories (written questions), requests for production (documents/ESI), requests for admission (admit or deny facts), and schedule depositions (live testimony) (Fed. R. Civ. P. 30, 33, 34, 36).
4
Responses and Objections
Usually 30 days after being served with the request, but can vary by rule or court order.
The receiving party must respond to requests within a specific timeframe, either providing the requested information/documents or formally objecting to the request and explaining why (e. R. Civ. P. 33(b), 34(b), 36(a)).
5
Discovery Disputes
As disputes arise, typically before the discovery cutoff.
If a party refuses to provide information or an objection is challenged, the parties may try to resolve the dispute informally. If they can't, the party seeking the information can file a 'motion to compel' with the court (Fed. R. Civ. P. 37(a)).
6
Expert Witness Disclosures
Typically 90 days before trial, or 30 days after the other side's expert disclosure for rebuttal.
Parties must identify any expert witnesses they plan to use at trial and provide a written report prepared and signed by the expert (Fed. R. Civ. P. 26(a)(2)).

Deadlines that can end your case

Meet and Confer
At least 21 days before a scheduling conference or scheduling order is due
Failing to meet can delay your case and incur court sanctions.
Initial Disclosures
Within 14 days after the Rule 26(f) conference
Failure to disclose can prevent you from using that evidence or witness at trial (Fed. R. Civ. P. 37(c)).
Responding to Interrogatories/Requests for Production/Requests for Admission
30 days after being served, unless otherwise stipulated or ordered
If you don't respond, the requests may be deemed admitted (Rule 36(a)) or you may waive your right to object.
Discovery Cutoff
Set by court's scheduling order, varies widely
No new discovery can generally be conducted after this date, so crucial evidence might be missed if you wait too long.

Costly mistakes

✕Not responding to discovery requests on time, which can lead to waived objections or requests being deemed admitted.
✕Hiding relevant evidence or providing false information, which can result in severe penalties, including dismissal of your case.
✕Failing to object to improper discovery requests, giving up your right to challenge them later.
✕Not understanding what information you are legally required to provide, even without a specific request (initial disclosures).
✕Ignoring the discovery cutoff deadline set by the court, meaning you can't get crucial evidence later.
✕Failing to cooperate with the other side in resolving discovery disputes, leading to unnecessary court involvement and potential sanctions.

Your checklist

Attend the Rule 26(f) 'meet and confer' conference with the other parties.
Prepare and send your initial disclosures as required by Fed. R. Civ. P. 26(a)(1).
Review initial disclosures received from the other side.
Identify what additional information and documents you need from the other side.
Draft and send appropriate discovery requests (interrogatories, requests for production, etc.).
Respond thoroughly and honestly to discovery requests you receive within the deadline.
Review your responses carefully for accuracy and completeness before sending them.
If you face a discovery dispute, attempt to resolve it informally with the other party.

Common questions

What if the other side refuses to give me information I know they have?

You should first try to resolve the issue directly with the other side. If that fails, you can file a 'motion to compel' with the court, asking the judge to order them to provide the information (Fed. R. Civ. P. 37(a)). The court can impose penalties if they continue to refuse.

Do I have to answer every single question or give every document they ask for?

You must answer relevant, non-privileged questions and provide relevant, non-privileged documents that are proportional to the case (Fed. R. Civ. P. 26(b)(1)). However, if a request is unclear, overly broad, or seeks privileged information (like attorney-client communications), you can formally object to it.

What is 'electronically stored information' (ESI) and how does it fit into discovery?

ESI includes things like emails, text messages, social media posts, digital documents, and data from computers or phones. It's treated like any other document in discovery and can be requested for production (Fed. R. Civ. P. 34). Parties must preserve ESI once litigation is reasonably anticipated.

Can I prevent certain information from being discovered?

Yes, if the information is 'privileged' (e.g., attorney-client communications) or 'protected' (e.g., attorney work product) (Fed. R. Civ. P. 26(b)(1), (b)(5)). You must specifically state the privilege you are claiming and describe the nature of the withheld documents in a 'privilege log' so the other side and the court can assess the claim.

What happens if I lie or hide evidence during discovery?

Lying or hiding evidence is very serious and can lead to severe penalties called 'sanctions' (Fed. R. Civ. P. 37(b), (c)). These can include monetary fines, having certain facts taken as true, being prevented from using certain evidence, or even having your entire case dismissed or a default judgment entered against you.

How this changes by state

While the Federal Rules of Civil Procedure govern cases in federal courts, each state has its own set of civil procedure rules. Most states base their rules on the federal rules, so the general concepts of discovery (initial disclosures, interrogatories, depositions) are very similar. However, the exact deadlines, the number of interrogatories allowed, the length of depositions, and specific procedures can vary significantly from state to state. To find your state's rules, search online for '[Your State] Rules of Civil Procedure' or consult your state's court website.

When you need a lawyer

Discovery is complex and highly technical. You need a lawyer if the opposing party is not cooperating, if you are unsure what information you must provide or can request, or if you need to object to discovery requests. Handling discovery improperly can result in your case being harmed, dismissed, or severe penalties being imposed against you.
