Pennsylvania Interrogatories: How Do You Respond?

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

In Pennsylvania state civil litigation, interrogatory answers must be written and verified, with each answer inserted in the space provided after its question or continued on a supplemental sheet. Pa.R.Civ.P. 4006(a)(2) requires service of the answers and any objections within 30 days after service of the interrogatories. The person making the answers signs them, while the attorney making objections signs those objections.

A plaintiff client who receives Pennsylvania interrogatories is usually asked about witnesses, treatment, and work history. The firm has to collect accurate facts and assemble a verified response in time.

This guide covers the Pennsylvania rules for answering interrogatories in discovery: the deadline, verification, objections, records option, enforcement, and supplementation. It closes with where Briefpoint fits in that work.

What rules govern Pennsylvania interrogatories and their limits?

Pennsylvania Rules of Civil Procedure 4005 and 4006 govern written interrogatories to parties and the answers to them. Rule 4005(c) does not impose a fixed numerical cap; it permits limits on the number of interrogatories or sets as justice requires to protect against unreasonable annoyance, embarrassment, oppression, burden, or expense. That is not a promise of unlimited discovery in a particular case.

An interrogatory is a written question one party serves on another party, who answers it; the serving party is the propounding party. Rule 4005 governs the questions, and Rule 4006 governs the answers. Under Rule 4005(a), the questions must leave sufficient space immediately after each interrogatory or subsection for the answer or objection. When the served party is a corporation, similar entity, partnership, or association, an officer or agent answers and must furnish the information available to the party, which is broader than the signer’s own memory.

Because Rule 4005(c) allows limits “as justice requires,” check the local rules and any case order before relying on a number from another state. A discovery response checklist is a useful base for the Pennsylvania items below.

What belongs on a Pennsylvania response checklist?

The following Pennsylvania interrogatory response requirements summarize statewide rule provisions, not a case-specific due-date calculation:

• Response period, Rule 4006(a)(2): Serve answers and objections within 30 days after service of interrogatories.
• Format, Rule 4006(a)(1): Written, verified answers in the spaces provided; overflow on a supplemental sheet.
• Signatures, Rule 4006(a)(2): Person making answers signs answers; attorney making objections signs objections.
• Meaning of verified, Rule 76, definition of “Verified”: Oath, affirmation, or statement subject to 18 Pa.C.S. § 4904 penalties.
• Number of questions, Rule 4005(c): No fixed numerical cap in this rule; limits may be imposed as justice requires.
• Objected-to questions, Rule 4006(a)(2): State reasons; answer all remaining questions without objections.
• Records option, Rule 4006(b): Derivable answer, substantially equal burden, specified records, reasonable access.
• Supplemental answers, Rule 4007.4(1)–(3): Seasonable updates in specified circumstances; other duties may arise by order, agreement, or request.

How long do I have to answer Pennsylvania interrogatories?

Under Pa.R.Civ.P. 4006(a)(2), the answering party must serve its answers and any objections within 30 days after service of the interrogatories. The deadline applies to the response, not just an acknowledgment or an unfinished draft. Determine the actual due date from the service information and applicable current rules and orders rather than treating a generic table as a case-specific calculation.

How the period is counted, and whether the method of service affects it, depends on current Pennsylvania time-computation and service rules that this article does not apply. Keep the proof of service, name the responsible attorney, and set the client’s information deadline and internal drafting milestones inside the rule’s period.

Who signs and verifies Pennsylvania interrogatory answers?

Pennsylvania Rule 4006(a)(1) requires written, verified interrogatory answers, and Rule 4006(a)(2) requires the person making the answers to sign them. Under Rule 76, “verified” includes an oath or affirmation or a statement made subject to the penalties of 18 Pa.C.S. § 4904. Verification therefore does not invariably require notarization, and an attorney’s signature on objections is not the answering person’s verification.

Rule 4006(a)(2) assigns signatures by role: the answers are signed by the person making them, and the objections by the attorney making them. The client reviews each answer for accuracy before signing, and the attorney reviews the objections and the whole response before service. Track the signed verification as its own item. This article does not offer a court-approved verification form, and the attorney decides what wording to use.

How should each answer appear in the document?

Rule 4006(a)(1) provides that “the answers shall be inserted in the spaces provided in the interrogatories,” and that if space is insufficient, “the remainder of the answer shall follow on a supplemental sheet.” Each answer stays with its question. See these interrogatory questions and answer examples for general formats.

The examples in this article are invented training illustrations, not forms ready to serve.

How do I object to Pennsylvania interrogatories without leaving the rest unanswered?

Pa.R.Civ.P. 4006(a)(2) requires each interrogatory to be answered fully and completely unless it is objected to, in which case the reasons must be stated instead of an answer. An objection to one interrogatory does not excuse answers to the remaining interrogatories to which no objection is stated. Rule 4011(b) and (e) prohibit discovery that would cause unreasonable burden or expense or require an unreasonable investigation.

Review the set one interrogatory at a time, tie each objection’s reason to that request, and have the attorney sign it. Answer every other question fully within the same 30 days. The common objections to interrogatories are a starting list, but a stock paragraph that does not connect the reason to the question may not state the reasons the rule calls for.

Suppose an interrogatory asks the plaintiff to identify every medical provider seen at any time in life. The attorney would identify the actual burden or unreasonable investigation, tie it to Rule 4011(b) or (e) if it applies, and consider answering for a defined period. Under Rule 4006(a)(2), the party submitting the interrogatories may ask the court to dismiss an objection and direct an answer. This illustration does not address privilege.

Can I answer Pennsylvania interrogatories by pointing to records?

Pa.R.Civ.P. 4006(b) permits a records-based answer when the answer can be derived from the responding party’s records and the burden of deriving it would be substantially the same for both sides. The response must specify the records and afford a reasonable opportunity to examine, audit, or inspect them and obtain copies, compilations, abstracts, or summaries. A generic “see documents” response does not establish those conditions.

All three elements must be present: a derivable answer, substantially the same burden for the serving party and the served party, and specified records with reasonable access. A Bates number is a document or page identifier. It helps specify records but does not itself show equal burden, and holding a production set does not settle that question. The attorney decides whether the option fits each interrogatory. On the document side, Autodoc finds responsive documents, adds page-level Bates citations, and builds a Bates-numbered production package.

What might a sufficiently specific records reference look like?

Take a question asking for the plaintiff’s wages in each month of 2025. If the figures can be derived from a defined set of payroll records and the burden would be substantially the same for both parties, the answer might identify those records, give the Bates range, and say how the other side can inspect and copy them.

By contrast, a broad reference to mixed medical, payroll, and correspondence files in response to a question about every supporting fact does not tell the reader which records contain the answer.

What happens if Pennsylvania interrogatory answers are late or incomplete?

Under Pa.R.Civ.P. 4019(a)(1)(i), a court may, on motion, make an appropriate order when a party fails to serve answers, sufficient answers, or objections to written interrogatories. Rule 4006(a)(2) also allows the propounding party to move to dismiss an objection and require an answer. Neither provision makes silence a safe response.

The orders described in Rule 4019(a) and (c) are available on motion; this summary does not cover every consequence of a discovery failure. Rule 4019(c)(2) lists an order refusing to allow the disobedient party to support or oppose designated claims or defenses, or prohibiting designated evidence, and Rule 4019(c) lists other orders. Under Rule 4019(a)(2), a failure to act “may not be excused on the ground that the discovery sought is objectionable unless the party failing to act has filed an appropriate objection or has applied for a protective order.”

Are attorney’s fees automatic on the first successful motion?

No. Rule 4019(g)(1) applies “except as otherwise provided in these rules” and describes a sequence: after opportunity for hearing, the court orders compliance; the order is not obeyed; and on a subsequent motion for sanctions, if granted, the court may require the responsible party, the attorney advising the conduct, or both to pay reasonable expenses, including attorney’s fees, incurred in obtaining the compliance order and the sanctions order. The court need not award them where the opposition was substantially justified or other circumstances make an award unjust. Other fee pathways are outside this article.

When must I supplement Pennsylvania interrogatory answers?

Pa.R.Civ.P. 4007.4 requires seasonable supplementation of specified witness and expert information and seasonable amendment when newly obtained information shows a prior answer was incorrect when made or is no longer true. A court order, party agreement, or new request before trial may also create a supplementation duty. The rule does not state a universal fixed number of days for every supplemental response.

A response “that was complete when made” carries no duty to supplement with later-acquired information except as the rule provides. Rule 4007.4(1) covers questions on the identity and location of persons with knowledge and on expert witnesses expected at trial; Rule 4007.4(2) covers a response known to be incorrect when made or no longer true; and Rule 4007.4(3) covers duties imposed by order, agreement, or new requests before trial. For example, if the client reports after service that a listed witness has moved, the team should consider a seasonable supplement under Rule 4007.4(1). Supplemental Responses is part of the workflow for later updates, and the attorney decides whether the rule, an order, an agreement, or a request requires one.

How can Briefpoint help prepare Pennsylvania interrogatory responses?

Briefpoint drafts responses and objections to interrogatories, with output editable in Microsoft Word and attorneys retaining final review. Client Bridge sends clients plain-language questions through a secure link so they can answer and upload documents for attorney review. These capabilities support gathering and drafting; the attorney still checks Pennsylvania rules, factual accuracy, verification, signatures, and service.

For a plaintiff-side team, this separates client fact collection from legal review. Client answers and uploaded documents give the attorney material to review; they do not establish that a response is complete or that an objection is appropriate. Keep the signed verification and service steps in the firm’s own review process.

FAQs about Pennsylvania interrogatories: What else should you know?

Pennsylvania interrogatory responses require attention to both the 30-day service period and the written, verified-answer requirements in Rule 4006. The questions below distinguish the numerical-limit, signature, objection, records, and fee rules that can otherwise be confused with procedures from other jurisdictions.

How many interrogatories are allowed in Pennsylvania?

Pennsylvania Rule 4005(c) does not set a fixed numerical cap on interrogatories or sets. It allows limits as justice requires to protect a party against unreasonable annoyance, embarrassment, oppression, burden, or expense. That does not establish an unlimited right to serve questions in a particular case; counsel must also review applicable local rules and case orders.

Do Pennsylvania interrogatory answers have to be notarized?

Not necessarily. Rule 4006(a)(1) requires verified answers, while Rule 76 defines verified to include an oath or affirmation or a statement made subject to the penalties of 18 Pa.C.S. § 4904. The person making the answers must sign them under Rule 4006(a)(2); an attorney’s signature on objections does not replace that requirement.

Does an objection stop the deadline for all Pennsylvania interrogatories?

An objection to one interrogatory does not excuse answers to the remaining questions without objections. Rule 4006(a)(2) requires the reasons for an objection and sets a 30-day period after service for serving answers and objections. A team should not treat one disputed question as permission to leave the rest of the response unfinished.

Can I answer an interrogatory with “see attached documents”?

Not merely because documents contain relevant information. Rule 4006(b) requires that the answer be derivable from the responding party’s records, with substantially the same burden for both parties. The response must specify the records and provide a reasonable opportunity to inspect them and obtain copies or related compilations. A blanket reference does not establish those requirements.

Are attorney’s fees automatic if a motion to compel is granted?

Not under the particular procedure in Pennsylvania Rule 4019(g)(1). Except as otherwise provided, that provision addresses a compliance order that is not obeyed, followed by a granted subsequent sanctions motion. It permits, rather than automatically requires, an award of specified expenses and attorney’s fees, subject to substantial justification or other circumstances making an award unjust.
