Federal Interrogatory Verification: Who Signs?

Legal content overseen by Nathan Walter, Esq., attorney licensed in California (State Bar No. 313299).

An in-house team with draft responses to interrogatories in discovery still has to decide who signs the federal interrogatory verification. In federal court, a corporation’s interrogatories are answered by an officer or agent who furnishes the information available to the corporation, and the person who makes the answers signs them.

A signed declaration under 28 U.S.C. § 1746 may take the place of a notarized oath.

This guide applies to federal civil litigation under the Federal Rules of Civil Procedure only. For the wider response process, see discovery response software and discovery support for in-house teams.

Who signs a corporation’s federal interrogatory verification?

Under Fed. R. Civ. P. 33(b)(1)(B), a corporation’s interrogatories must be answered “by any officer or agent, who must furnish the information available to the party.” Rule 33(b)(3) requires each interrogatory, to the extent it is not objected to, to be “answered separately and fully in writing under oath.” Rule 33(b)(5) adds that “the person who makes the answers must sign them.”

In this article, “verification” means the written oath or qualifying declaration that accompanies the answers. It does not mean counsel’s ordinary signature on objections, which Rule 33(b)(5) treats separately.

Two roles are involved in a corporate response:

• The corporate signer: the officer or agent who furnishes the information available to the corporation and signs the answers.
• The legal reviewer: the attorney who reviews the draft and signs any objections.

The rule’s text names “any officer or agent.” It does not say that only a chief executive may sign, and it does not say that every employee qualifies as an agent. Whether a particular person is an officer or agent is a question for the responsible attorney.

Does the corporate signer need firsthand knowledge of every answer?

Rule 33(b)(1)(B) calls for “the information available to the party,” so the answers are not limited to what the signer personally remembers. The officer or agent answers for the organization using the information the organization has. Rule 33(b)(3) still requires separate, full written answers under oath to the extent no objection applies.

One workflow for a corporate response follows. It is a practice suggestion, not a federal form:

1. Identify which departments hold information relevant to each interrogatory.
2. Gather the records and written factual input from those departments.
3. Reconcile any inconsistent information before the answers are finalized.
4. Give the signer the exact final answer set to review before the oath or declaration is signed.

The following hypothetical is invented for illustration. A former employee sues a company for unpaid overtime, and an interrogatory asks the company to state the hours the plaintiff worked each pay period.

The officer who will sign the answers consults payroll and human resources records as part of gathering the information available to the company. The outside lawyers then check the draft against those records before the officer signs.

Can outside counsel sign the objections instead of the answers?

Rule 33(b)(5) assigns separate signature responsibilities for answers and objections: “The person who makes the answers must sign them, and the attorney who objects must sign any objections.” An attorney’s signature on objections does not satisfy the separate requirement that the person who makes the answers sign them. Rule 33(b)(3) also keeps the oath requirement for the parts of an interrogatory that are not objected to.

This article does not address whether a specific attorney could qualify as an agent of the corporation in a separate capacity. That question depends on facts and authority outside the sources reviewed here.

On objections, Rule 33(b)(4) states: “The grounds for objecting to an interrogatory must be stated with specificity. Any ground not stated in a timely objection is waived unless the court, for good cause, excuses the failure.” For typical grounds, see common objections to interrogatories. That page is general background, not authority for federal procedure.

When an objection covers only part of an interrogatory, the corporate signer signs the answers to the unobjected portions, and the attorney signs the objections.

Does federal interrogatory verification need a notary?

A qualifying written declaration under 28 U.S.C. § 1746 may support a matter “with like force and effect” as a sworn statement, without notarization. The declaration must be in writing, subscribed by the person making it as true under penalty of perjury, and dated, in substantially the form the statute gives. The statutory wording differs for execution inside and outside the United States.

Section 1746 applies where a law, rule or order requires or permits a matter to be supported by a “sworn declaration, verification, certificate, statement, oath, or affidavit, in writing.” It carves out a deposition, an oath of office, and an oath required to be taken before a specified official other than a notary public. The full text is at 28 U.S.C. § 1746.

Here is the language for each execution location:

• Executed within the United States, its territories, possessions, or commonwealths, § 1746(2): “I declare (or certify, verify, or state) under penalty of perjury that the foregoing is true and correct. Executed on (date). (Signature)”
• Executed outside the United States, § 1746(1): “I declare (or certify, verify, or state) under penalty of perjury under the laws of the United States of America that the foregoing is true and correct. Executed on (date). (Signature)”

The only difference in the overseas version is the added phrase “under the laws of the United States of America.” Use the statute’s actual wording for the place where the signer executes the declaration.

This section covers only the federal statute. Electronic signatures, local or judge-specific forms, and whether the paperwork in a given case is sufficient are for the responsible attorney to confirm.

When are signed answers due, and what if the response is incomplete?

Under Rule 33(b)(2), federal interrogatory answers and objections are due within 30 days after service unless a shorter or longer time is stipulated to under Rule 29 or ordered by the court. Fed. R. Civ. P. 37(a)(3)(B)(iii) permits a motion to compel when a party fails to answer an interrogatory submitted under Rule 33. Rule 37(a)(4) states: “For purposes of this subdivision (a), an evasive or incomplete disclosure, answer, or response must be treated as a failure to disclose, answer, or respond.”

Rule 33(b)(5) requires the person making the answers to sign them, so the corporate signer’s review belongs inside the applicable response window. Under Rule 37(a)(1), a party may move to compel on notice to other parties and all affected persons. The motion must include a certification that the movant “has in good faith conferred or attempted to confer with the person or party failing to make disclosure or discovery in an effort to obtain it without court action.”

This article does not say that any verification defect leads to a particular outcome. It does not address deemed admissions, dismissal or sanctions, and it does not identify a grace period for a missing verification.

FAQs about federal interrogatory verification: what else should teams know?

Federal interrogatory verification turns on who makes and signs the answers under Rule 33(b), and whether the written oath or declaration meets the applicable federal requirements. Section 1746 supplies qualifying declaration language, but it does not replace Rule 33’s separate allocation of answer and objection signatures.

Who can sign interrogatory answers for a corporation in federal court?

An officer or agent may answer for a corporation under Rule 33(b)(1)(B), furnishing the information available to the corporate party. The person who makes the answers must sign them under Rule 33(b)(5). The rule does not limit signing to the chief executive, and it does not treat every employee as an agent, so the responsible attorney should assess the signer’s status.

Does a federal interrogatory verification need to be notarized?

Not when a qualifying declaration under 28 U.S.C. § 1746 is used in place of the sworn verification. The statute calls for a signed, dated declaration made as true under penalty of perjury, and it supplies different wording for execution inside and outside the United States. Its exceptions, including depositions, remain in force.

Can my lawyer’s signature on objections replace the verification?

No. An attorney’s signature on objections does not fulfill Rule 33(b)(5)’s separate requirement that the person making the answers sign them. Rule 33(b)(3) continues to require answers under oath to the extent an interrogatory is not objected to. Whether counsel could also act as a corporate agent is a separate question this article does not decide.

Does the corporate signer have to know every fact personally?

Rule 33(b)(1)(B) requires the officer or agent to furnish the information available to the corporate party, which is broader than personal recollection. The record-gathering and department-review sequence in this article is a suggested workflow for developing those answers. It is not a prescribed federal form, and it does not decide whether a particular person qualifies as an agent.

What if the person signing is outside the United States?

Section 1746(1) supplies the wording for execution outside the United States. It says the declarant states the foregoing is true and correct “under penalty of perjury under the laws of the United States of America,” and it includes the execution date and signature. Use that statutory language rather than treating the domestic and overseas forms as identical.
