Sequester Meaning

To sequester means to separate or place something under legal control, but the precise legal meaning depends on what is being sequestered. In a trial, the term may concern jurors protected from outside influences or witnesses excluded from hearing other testimony. In a property dispute, it can concern seizure under a particular legal remedy.

Start with the object of the order: jurors, witnesses or property. A witness told to wait outside is not necessarily subject to the hotel-and-contact restrictions associated with a sequestered jury. A property writ is a different process altogether.

How can you tell which meaning applies?

Read the court's order or the document using the term, then match its purpose and subject:

The order matters as much as the label. Identify who is covered, what conduct is restricted, how long the restrictions last and whether any exceptions apply. In news about a trial, juror protection may be the intended meaning; in an instruction directed to witnesses, exclusion from testimony is the more relevant starting point.

What does it mean to sequester a jury?

Jury sequestration protects the decision-making process from outside influence, such as publicity, improper contact or pressure. It can involve keeping jurors together under court supervision and limiting outside communications. The particular arrangements come from the court's instructions.

The California judiciary's jury-service glossary describes sequestration as extremely rare and explains that a sequestered jury is usually housed together overnight in a hotel. It identifies media exposure and, in rare cases, attempts to influence deliberations through threats as reasons for protection.

That is not an assertion that all trials require overnight isolation. The U.S. Courts' guide to covering criminal trials likewise describes a judge deciding to sequester a jury in exceptional cases. A routine instruction not to research a case does not, by itself, establish that jurors have been ordered into full sequestration.

Courtroom example: During a heavily publicized trial, the judge orders protected overnight accommodation and specific limits on communications to shield jurors from outside influence. The jurors must follow those instructions; they should not infer permission to read online coverage merely because another trial allowed its jurors to go home. This example illustrates the purpose, not a prediction that publicity always produces sequestration.

The term can also appear during jury selection. California's current Standard 4.30(a)(3) permits consideration of sequestered voir dire for sensitive matters or questions about media reports. Individualized questioning at that stage is distinct from housing a selected jury together throughout a trial. Check which procedure the speaker actually means.

What does it mean to sequester witnesses under Rule 615?

Witness sequestration addresses a different risk: a witness hearing another person's account and adjusting later testimony to match or counter it. Separating covered witnesses helps preserve their independent accounts.

Under Federal Rule of Evidence 615, the court must exclude covered witnesses from the courtroom at a party's request, and may do so on its own. The rule specifies exceptions. It does not authorize excluding:

• A party who is a natural person.
• One designated officer or employee representing a party that is not a natural person.
• A person whose presence a party shows is essential to presenting its claim or defense.
• A person authorized by statute to be present.

An expert is not automatically exempt merely because they are an expert. Whether the essential-person exception or another protection applies requires examining the role and the governing rule.

A significant distinction appears in Rule 615(b): an exclusion order under subdivision (a) only excludes witnesses from the courtroom. The court may separately prohibit disclosure of trial testimony to those witnesses and prohibit them from accessing it. Thus, leaving the room does not answer every question about transcripts, livestreams, messages or accounts of what another witness said. Read the full order rather than assuming either unrestricted access or an automatic ban on every conversation.

Courtroom example: Two witnesses saw the same delivery. One waits outside while the other testifies. If the court also prohibits access to trial testimony, sending the waiting witness a live account by message can violate that additional restriction. The witness's physical absence from the courtroom would not answer the separate access issue.

Federal terminology does not establish the rule everywhere. The Massachusetts Guide to Evidence, Section 615, adopted February 1, 2026, uses may for witness exclusion at a party's request and identifies protected parties. That contrasts with the federal rule's must, subject to its exceptions. The applicable jurisdiction and order determine the procedure.

What does property sequestration mean?

Property sequestration concerns control or seizure of an asset under a specific legal process. It is not witness isolation, and it should not be treated as a generic synonym for every asset freeze or attachment.

Louisiana provides a concrete U.S. example. Under Code of Civil Procedure Article 3571, a person claiming ownership, possession or a specified interest in property may seek its seizure under a writ of sequestration when the defendant has the power to conceal, dispose of, waste or remove the property in the circumstances described by the article while the action is pending.

Article 3501 requires specific verified facts supporting the claim and grounds, together with security as required by law. It addresses both attachment and sequestration; sharing procedural provisions does not make the remedies interchangeable or dispense with the grounds for the particular writ.

Property-dispute example: Parties dispute possession of equipment, and the applicant alleges facts showing that the defendant can conceal or dispose of it during the case. A Louisiana sequestration request requires the relevant property interest, statutory grounds and procedural support. The allegation alone does not give the applicant permission to take the equipment personally, or establish the final ownership outcome.

There are procedures for challenge as well. Article 3506 allows the defendant to seek dissolution by contradictory motion unless the plaintiff proves the grounds, and permits damages for wrongful issuance in the circumstances stated there. This reinforces the distinction between a provisional writ and a final resolution of the underlying dispute.

Does sequestration mean the same thing in every jurisdiction?

No. Apart from different trial rules, the word can identify an entirely different process. The Scottish Courts and Tribunals Service explains that sequestration in Scotland means bankruptcy. That usage concerns insolvency, not separating witnesses or placing jurors in a hotel.

For any document, use this short check:

1. Find the subject: juror, witness, specific asset or insolvency proceeding.
2. Identify the authority: court, jurisdiction, rule, statute and actual order.
3. Read the operative restrictions: physical location, communications, testimony access or control of property.
4. Check exceptions and duration: do not assume every person is covered or that every order lasts the whole trial.
5. Clarify uncertainty before acting: ask counsel or the court through the appropriate procedure about the order's scope rather than guessing from an everyday definition.

The shared idea is separation or legal control. The practical consequences come from the particular procedure and order, which is why jury, witness, property and bankruptcy uses must be kept distinct.
