The witness sequestration rule, found at Federal Rule of Evidence 615, requires a federal court to order witnesses out of the courtroom at a party’s request so they cannot hear each other testify. The judge has no discretion to refuse once a party asks. Nearly every state has adopted a close version of the same rule, and the point is simple: keep each witness’s account independent by removing both the temptation and the unconscious tendency to shade testimony to match what someone else just said.1Legal Information Institute.

How to Invoke the Rule
Invoking sequestration is one of the simplest motions in trial practice. An attorney stands and asks the court to “invoke the rule” or to exclude witnesses under Rule 615. The court must then order all non-exempt witnesses out. A judge can also issue the order on their own, though that is rare because one side almost always wants it.1Legal Information Institute. Federal Rules of Evidence Rule 615 – Excluding Witnesses
There is no deadline. Most attorneys invoke the rule at the very start of trial, before any testimony begins, which eliminates overlap entirely. But the advisory committee notes confirm that no specific time is required. A party can invoke it mid-trial if the need only becomes clear once testimony is underway.1Legal Information Institute.

Who Is Allowed to Stay in the Courtroom
Rule 615 lists four categories of people who cannot be excluded, no matter who objects.
Natural-Person Parties
A party who is a natural person cannot be excluded from their own trial. That protection reflects the right to be present and to confront the evidence against you.1Legal Information Institute. Federal Rules of Evidence Rule 615 – Excluding Witnesses
A Designated Representative for an Entity
When a party is a corporation, government agency, or other organization, the party’s attorney may designate one officer or employee to remain in the courtroom throughout the trial. If the entity wants a second person present, that person must separately qualify as an essential person.1Legal Information Institute. Federal Rules of Evidence Rule 615 – Excluding Witnesses
Essential Persons
A party can also keep a witness in the courtroom by showing the judge that the witness’s presence is essential to presenting its claim or defense. This is not automatic. The advisory committee notes point to people like an agent who handled the transaction at the center of the case or an expert who needs to hear live testimony to advise the legal team. Experts often fit here, but a party still has to explain why that particular expert needs to be there. An expert whose opinion rests entirely on pre-trial document review may not clear the bar.1Legal Information Institute. Federal Rules of Evidence Rule 615 – Excluding Witnesses
Crime Victims and Others Authorized by Statute
The fourth exemption covers anyone a statute authorizes to attend. In federal criminal cases, that primarily means crime victims. Under the Crime Victims’ Rights Act, a victim has the right not to be excluded from any public court proceeding unless the court finds, by clear and convincing evidence, that the victim’s testimony would be materially altered by hearing other witnesses. Before excluding a victim, the court must consider alternatives and must state its reasons on the record.2Office of the Law Revision Counsel. 18 USC 3771 – Crime Victims Rights
What Excluded Witnesses Cannot Do
Staying out of the room is only the baseline. Excluded witnesses should not discuss the substance of the case or their anticipated testimony with other witnesses who have not yet testified. Attorneys carry much of this responsibility, because most witnesses are not repeat players and may not realize that a casual hallway conversation can create a serious problem.
For decades, Rule 615 said nothing about transcripts, media coverage, or secondhand summaries. The risk of tailored testimony is just as real whether a witness hears earlier testimony live or reads it the next morning. A 2023 amendment closed that gap by adding subdivision (b), which gives courts explicit authority to prohibit disclosing trial testimony to excluded witnesses and to prohibit excluded witnesses from accessing testimony by any means. These are separate, discretionary orders a judge can tailor to the case.1Legal Information Institute. Federal Rules of Evidence Rule 615 – Excluding Witnesses3United States Courts. Federal Rules of Evidence Pamphlet December 1, 2023
When a court issues an order under subdivision (b), witnesses may be barred from reading transcripts of earlier testimony, reviewing media coverage, or receiving summaries from anyone who was in the room. Social media creates a modern complication. A sequestration order will not usually name Twitter or any other platform by name, but a witness scrolling through posts about another witness’s testimony has effectively circumvented the order. Lawyers should warn their witnesses about this directly.
Does the Rule Apply to Depositions?
No. Federal Rule of Civil Procedure 30(c)(1) specifically excludes Rule 615 from the rules governing depositions, so simply “invoking the rule” does not clear other witnesses from a deposition room. A party who wants exclusion at a deposition has to seek a protective order under Federal Rule of Civil Procedure 26(c)(5) and persuade the court that exclusion is appropriate under the circumstances. If the court grants exclusion, it should also consider whether the excluded witnesses need to be barred from reading the transcript afterward.4Legal Information Institute.

Consequences for Violating the Order
There is no fixed penalty for breaking a sequestration order. Courts look at whether the violation was accidental or deliberate and how much exposure to other testimony actually occurred. The response scales with the severity of the problem.5National Institute of Justice. Law 101 Legal Guide for the Forensic Expert – Sequestration
At the lighter end, the judge may allow the witness to testify but give the jury a curative instruction describing the violation so jurors can weigh it when assessing credibility. Cross-examination usually brings it out as well, and that often does more damage than the instruction itself.
For more serious violations, the court can strike the witness’s testimony or bar the witness from testifying at all. Courts reserve this response primarily for intentional or willful violations. A witness who deliberately sat in the gallery during earlier testimony, or who sought out transcripts after being told not to, faces a much harsher response than one who accidentally overheard a comment in the hallway.5National Institute of Justice. Law 101 Legal Guide for the Forensic Expert – Sequestration
Contempt of court is also on the table. Federal courts have statutory power to punish disobedience of a lawful court order by fine, imprisonment, or both, and the statute does not set specific dollar amounts or time limits.6Office of the Law Revision Counsel. 18 USC 401 – Power of Court That gives trial judges wide discretion to match the sanction to the violation.
