FRCP Rule 26 Explained: Initial Disclosures and Discovery Scope

Short answer: Rule 26 is a rule in the Federal Rules of Civil Procedure, the court rules for civil lawsuits in United States federal courts. It says what each side must hand over without being asked. It also says how far the other side's requests can reach. The first handover is called initial disclosures. It is due at or within 14 days after the parties' planning meeting, the Rule 26(f) conference, unless the parties or the judge set another time. Every other request must be relevant to a claim or defense. It must also be proportional to the needs of the case, meaning in line with what is at stake.

TL;DR

• Four things are due without a request. They are the people and documents you may use, a damages computation, and any insurance agreement that may cover a judgment. Nine kinds of proceeding are exempt.
• Discovery has two tests. Information must be relevant to a claim or defense. It must also be proportional to the needs of the case. The rule lists six factors for that.
• The planning meeting sets the calendar. Since December 1, 2025, the plan must also cover when and how the parties will describe material they hold back as privileged.
• Check the date on your copy. The official pamphlet is dated December 1, 2025. A change to Rule 26 is proposed for December 1, 2027. A proposal is not law.

Official text, as of 12 October 2026

This was read on 12 October 2026 in the Federal Rules of Civil Procedure Pamphlet, Dec. 1, 2025, the courts' own copy. Rule 26(b)(1) begins: "Parties may obtain discovery regarding any nonprivileged matter that is relevant to any party's claim or defense and proportional to the needs of the case". The source line at the end of the rule ends "Apr. 23, 2025, eff. Dec. 1, 2025".

What changed in 2025 and 2026. The 2025 amendment changed Rule 26(f)(3)(D), covered below. Nothing new takes effect in 2026. The judiciary's pending amendments page lists no Civil Rules for December 1, 2026. It does list Civil Rules 7.1, 26, 41, 45 and 81 for December 1, 2027. It says such dates can be delayed or withdrawn.

Where Rule 26 sits

The civil rules "govern civil proceedings in the United States district courts," in the judiciary's words. The Supreme Court adopted them by order on December 20, 1937. They took effect September 16, 1938. State courts have their own rules. So do the criminal, appellate and bankruptcy courts. Our guide to federal versus state law explains which system covers a dispute.

Court rules are one kind of primary law, meaning the official text of the law itself. Our guide to the types of primary law lists the rest. Rule 26 opens the part of the civil rules called Disclosures and Discovery. Discovery is the stage where each side collects information from the other. The other rules a first case puts in front of you are in the Federal Rules of Civil Procedure in plain English.

The map of Rule 26

Initial disclosures, one item at a time

Rule 26(a)(1)(A) says a party must hand over four things "without awaiting a discovery request."

1. People. The name of each person who is likely to have discoverable information that you may use to support your claims or defenses. Discoverable means the other side is allowed to ask about it. Add the address and phone number if you know them, plus the subjects the person knows about.
2. Documents. A copy, or a description by category and location, of the documents, electronic data and physical things you hold and may use to support your side.
3. Damages. A computation of each category of damages you claim, plus the documents it rests on.
4. Insurance. The rule calls for "any insurance agreement under which an insurance business may be liable to satisfy all or part of a possible judgment." The other side may inspect and copy it.

The fourth item surprises many business readers. A liability policy that could pay a judgment is part of a standard first disclosure. Ask counsel which of your policies could be one, and whether the insurer knows about the case.

Notice the words "may use." The first handover is about your own side. Anything you would use only to attack a witness's credibility is left out. The other side's requests for more fall under the scope rule, covered next.

Who is exempt. Rule 26(a)(1)(B) names nine kinds of proceeding that skip this step. A business might meet three. One is an action for review on an administrative record. Another is an action to enforce or quash an administrative summons or subpoena. The third is an action to enforce an arbitration award.

When it is due. The default is at or within 14 days after the Rule 26(f) conference. The parties or the court can set a different time. A party can also object at the conference that disclosures are not right for this case, and put that in the proposed plan. The court then decides what is handed over and when. A party served or joined after the conference has 30 days.

No excuses. You work from the information "then reasonably available". You are not excused because you have not finished investigating. The other side's silence is no excuse either.

Two later disclosures sit in the same rule. Absent a stipulation or order, expert disclosures are due at least 90 days before trial. Trial witnesses and exhibits follow at least 30 days before trial.

What discovery can reach

Rule 26(b)(1) allows discovery of anything that passes two tests.

• Relevant. It must bear on a party's claim or defense. It must also be nonprivileged. That means no legal privilege, such as attorney-client confidentiality, protects it.
• Proportional. It must fit the needs of the case. The rule says to weigh six things. Those are the importance of the issues and the amount in controversy. Then come each side's access to the information and each side's resources. The last two are how much the discovery would help resolve the issues, and whether its burden or cost outweighs its likely benefit.

The rule adds that information "need not be admissible in evidence to be discoverable". A document can be requested even if it might not be admissible at trial.

Where the wording came from. The 2015 committee note says the amendment "restores the proportionality factors to their original place" in the scope rule. The same note says it does not let a party refuse discovery "simply by making a boilerplate objection that it is not proportional". It adds that a party claiming undue burden or expense ordinarily has far better information about that burden than the other side. A bare label does little. A specific cost does more. The note explains the rule. It is not the rule. The note text quoted here comes from Cornell's Rule 26 page, an unofficial copy.

Limits beside the scope rule.

• A party need not hand over electronic data from sources it says are too costly or burdensome to reach. A court can still order it for good cause.
• Documents prepared for litigation are ordinarily shielded from discovery.
• A party that holds something back as privileged must say so. It must describe the material so other parties can judge the claim, without giving away the privileged content.
• Anyone can ask the judge for a protective order against "annoyance, embarrassment, oppression, or undue burden or expense". The request must say the person first tried in good faith to settle the dispute.

The Rule 26(f) conference and the 2025 change

The parties must meet "as soon as practicable." The rule sets a floor: at least 21 days before a scheduling conference is held or a scheduling order is due. A scheduling order is the judge's order setting the dates for the case. Within 14 days after the meeting, the lawyers send the court a written discovery plan. Parties without a lawyer share that duty.

The plan states the parties' views on six topics.

1. Changes to when and how initial disclosures are made.
2. The subjects of discovery, when it should end, and whether it should run in phases.
3. Electronic data: how to keep it, and the form it will be handed over in.
4. Privilege claims. This covers the timing and method for describing withheld material. It also covers whether to ask for an order under Federal Rule of Evidence 502 that records any after-production agreement.
5. Changes to the limits on discovery.
6. Any other orders the court should enter.

The 2025 change is in item 4, which is Rule 26(f)(3)(D). The committee note says describing withheld material "can involve very large burdens for all parties." A privilege log is the list of what a party is holding back and why. The note warns that one produced "near the close of the discovery period can create serious problems." It also says "rolling" production is often valuable. A companion change to Rule 16(b)(3)(B)(iv) nudges the judge to cover the same topic in the scheduling order.

Timing, supplementing and signing

Rule 26(d)(1) bars discovery "from any source" before the Rule 26(f) conference. There are exceptions for exempt cases, and for the rules, a stipulation or a court order. One exception helps planning. More than 21 days after the summons and complaint are served, a party may deliver a document request early. It counts as served at the first conference.

If you learn that a disclosure is incomplete or wrong in a material way, you must fix it "in a timely manner." A lawyer's signature on a disclosure says it is complete and correct when made, after a reasonable check. If that certification is false without substantial justification, Rule 26(g)(3) says the court must impose an appropriate sanction. Rule 37 covers failure to make disclosures or to cooperate in discovery.

A short history

The 1993 amendments created the duty to disclose without a request, but let each district opt out by local rule. The 2000 committee note describes "a striking array of local regimes". The 2000 amendment then set one national practice. Its committee note adds that local rules and general standing orders can no longer create exemptions. An order in a single case is still proper. In 2015, proportionality moved into the scope rule. In 2025, privilege timing joined the plan.

What goes wrong

• Reading an old copy. The judiciary keeps a separate page of superseded rules pamphlets, so earlier versions exist. Ask: what date is on the cover of my copy?
• Treating 14 days as fixed. It is a default. Ask: did a stipulation or the scheduling order set another time?
• Reading initial disclosures as everything the other side can ask for. They cover what a party may use. Other requests run through the scope rule.
• Missing the insurance item. Ask: who holds our policies?
• Objecting with a label. The 2015 note disfavors boilerplate. Ask: what specific burden or expense are we claiming?
• Leaving privilege for last. The 2025 note warns about a late log. Ask: what did our plan say about timing and method?
• Mixing up rule sets. A state may have a rule with the same number. Ask: which court is this, and whose rules apply?

How to read the rule yourself

1. Open the courts' current pamphlet and read the date on the cover.
2. Read the source line at the end of Rule 26 for its latest amendment.
3. Read the scheduling order, the judge's own orders and the court's local rules. They can set dates and limits within what the rules allow. Rule 26(f)(4), for example, lets a court shorten the conference and report deadlines by local rule.

FAQ

What is FRCP Rule 26?

It is the rule that covers disclosures and the limits on discovery in federal civil cases. It sets what each side hands over unasked and what the other side may request. It also covers protective orders and the planning meeting. It does not apply in criminal cases or in state courts.

What are initial disclosures under Rule 26?

They are four items a party hands over without waiting for a request: the people and documents it may use, a damages computation, and any insurance agreement that may pay a judgment. Nine kinds of proceeding are exempt.

When are initial disclosures due under FRCP 26?

At or within 14 days after the Rule 26(f) conference, unless a stipulation or court order sets another time. A party who objects at the conference gets a ruling from the court. A party served or joined later has 30 days. Check the scheduling order in your case.

What is the scope of discovery under Rule 26(b)(1)?

Nonprivileged matter that is relevant to a claim or defense and proportional to the needs of the case. Six factors guide proportionality, from the importance of the issues to the burden or cost. The information does not have to be admissible in evidence.

What is a Rule 26(f) conference?

It is the planning meeting the parties must hold early, at least 21 days before a scheduling conference or order. They discuss the case, arrange disclosures, talk about keeping evidence, and write a discovery plan. The written report is due to the court within 14 days after the meeting.

Does Rule 26 apply in state court?

No. Each state has its own rules of civil procedure, and many follow the federal ones. A state rule with the same number may say something different. Our state court rules guide explains how to find them.

Did Rule 26 change recently?

Yes. An amendment effective December 1, 2025 changed Rule 26(f)(3)(D). The discovery plan must now cover the timing and method for describing material withheld as privileged. Another change, to Rule 26(a)(3)(A)(i), is listed for December 1, 2027. It would have each party say whether it expects each trial witness to testify in person or remotely. It was published for comment in August 2025. The rules committee's September 2026 report recommends approval. The Supreme Court has not adopted it. It is proposed. It is not law.
