Personal Injury Discovery Responses: A Plaintiff’s Guide

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

Defense requests often arrive while your client is still treating, so answers about providers, prior injuries and damages may change before the case ends. Personal injury discovery responses in federal court involve four jobs: assemble the facts and records, answer each request type under its own rule, get the signatures that rule requires, and update material answers as treatment continues.

This is a federal-court guide to Federal Rules of Civil Procedure Rule 26, Rule 33, Rule 34 and Rule 36. It does not address state-court rules.

The steps below connect medical records and damages calculations to drafting, signatures and material updates.

What are personal injury discovery responses?

Personal injury discovery responses are the plaintiff’s written answers and objections to the defense’s interrogatories, requests for production (RFPs) and requests for admission (RFAs). For the general framework, see our federal discovery response guide and how AI discovery responses work.

Responses to requests differ from initial disclosures, which Rule 26(a)(1)(A) requires a party to provide without awaiting a discovery request, subject to the exemptions in Rule 26(a)(1)(B) and any stipulation or order.

The federal baselines for request-driven responses:

• Interrogatories (Rule 33): answers and objections are due within 30 days after service. Each interrogatory, to the extent it is not objected to, must be answered separately and fully in writing under oath, and objections must be specific (Rule 33(b)(2)–(4)).
• Requests for production (Rule 34): the written response is due within 30 days after service (or within 30 days after the first Rule 26(f) conference for a request delivered under Rule 26(d)(2)). Each item gets a statement that inspection will be permitted or a specific objection with reasons (Rule 34(b)(2)(A)–(B)).
• Requests for admission (Rule 36): a matter is admitted unless, within 30 days after service, the responding party serves a written answer or objection addressed to the matter and signed by the party or its attorney (Rule 36(a)(3)).

Each of those rules allows a shorter or longer time by stipulation under Rule 29 or by court order.

1. Map the defense requests to the client’s records

Build the collection checklist from the requests. Each request is still measured against Rule 26(b)(1): discovery reaches nonprivileged matter that is relevant to a party’s claim or defense and proportional to the needs of the case, and it need not be admissible to be discoverable.

An RFP reaches items within the responding party’s possession, custody, or control, including electronically stored information (ESI) (Rule 34(a)(1)).

Medical history, prior injuries and treating providers

For each claimed injury, gather:

• the incident date and each body part or condition the complaint claims;
• prior and later injuries or conditions involving those body parts, and any prior claims;
• each treating provider, with treatment dates, records and bills.

Keep the client’s recollection separate from what the records confirm, and track open questions in a checklist.

The cited rule text sets no fixed lookback period. How far back a request may reach turns on relevance and proportionality under Rule 26(b)(1).

Treat a request to sign a medical authorization separately from a request to produce existing records. Whether an authorization must be signed, and whether a provider’s records are in the client’s control under Rule 34(a)(1), are case-specific questions to research.

Wage loss, photographs, social media and insurance

Inventory the employers, missed-work dates and wage statements that support claimed earnings loss, along with photographs and any posts, messages or videos a request describes. For ESI, check each request’s subject matter, date range and requested form. If you object to the form, or none was given, the response must state the form you intend to use (Rule 34(b)(2)(D)).

Rule 26(a)(1)(A)(iv) covers an insurance agreement under which an insurance business may be liable to satisfy a possible judgment or to indemnify or reimburse payments made to satisfy it. Evaluate a request about the plaintiff’s health-insurance payments under the nonprivileged relevance and proportionality standard in Rule 26(b)(1); that provision does not make all such payment information discoverable automatically.

2. Build a supported damages computation

Under Rule 26(a)(1)(A)(iii), a party subject to initial disclosures must provide, without awaiting a request, a computation of each category of damages it claims. It must also make available for inspection and copying under Rule 34 the documents or other evidentiary material supporting each computation, including materials bearing on the nature and extent of injuries, unless privileged or protected. The computation rests on information then reasonably available, and incomplete investigation is not an excuse (Rule 26(a)(1)(E)).

The examples in this guide, including these figures and the response excerpts, are invented. A worksheet might look like this:

• Medical expenses: emergency department $3,200; orthopedic consultation $1,450; physical therapy $2,100. Subtotal $6,750, each line tied to its bill.
• Past lost wages: 12 missed eight-hour shifts × $25 per hour = $2,400, tied to the pay stubs and the employer’s attendance records.
• Future losses and noneconomic damages: one line per category claimed, with its present basis and unresolved inputs.

List unresolved inputs openly instead of inventing precision. Under Rule 26(e)(1), timely supplement or correct a materially incomplete or incorrect disclosure if the corrective information has not otherwise been made known during discovery or in writing, or as the court orders.

3. Draft answers and objections that fit each request

Answer interrogatories from checked facts

Each interrogatory must, to the extent it is not objected to, be answered separately and fully in writing under oath (Rule 33(b)(3)). An interrogatory may ask for an opinion or contention that relates to fact or the application of law to fact (Rule 33(a)(2)).

A promise to supplement does not replace a full answer based on the facts available when responding. “See the medical records” is not automatically a complete answer. Rule 33(d) permits this option when the answer can be determined from a party’s business records and the burden of deriving it is substantially the same for either party. The responding party must identify the records so the other side can locate and identify them as readily as the responding party can, and give a reasonable opportunity to examine and audit them and make copies, compilations, abstracts or summaries.

Narrow medical-history requests and separate privacy from privilege

Take a request for every provider who has treated the client “at any time in your life.” Identify the excessive scope, explain whether and how it connects to the pleaded injuries and defenses, and answer the portion that is not objectionable. A ground not stated with specificity in a timely objection is waived unless the court excuses the failure for good cause (Rule 33(b)(4)).

Nothing in the text of these four rules treats medical records as privileged as such. Privacy is addressed through scope under Rule 26(b)(1) and, for good cause, a protective order under Rule 26(c)(1). A motion for one must certify a good-faith conference or attempt to resolve the dispute without court action.

When you withhold information as privileged or as trial-preparation material (see Rule 26(b)(3)(A)), Rule 26(b)(5)(A) requires you to expressly make the claim and describe what was withheld so the other side can assess it, without revealing the protected information. Rule 26(b)(5)(A) specifies what the description must convey, not a particular log template. A privilege log can organize that description, but it must provide enough information for the other parties to assess the claim without revealing protected information.

Keep production responses and admissions distinct

A production response states, for each item or category, that inspection will be permitted or the specific grounds for objecting, with reasons. An objection must say whether responsive materials are being withheld, and an objection to part of a request must specify the part and permit inspection of the rest. Production must be completed by the time in the request or another reasonable time stated in the response (Rule 34(b)(2)(B)–(C)).

For requests for admission, a matter not admitted must be specifically denied, or the answer must state in detail why the party cannot truthfully admit or deny it. Lack of knowledge is a permitted reason only if the party states that it made reasonable inquiry and the information it knows or can readily obtain is insufficient. A party must not object solely because the request presents a genuine issue for trial (Rule 36(a)(4)–(5)).

4. Obtain client verification and complete attorney review

Signature requirements differ by request type. For interrogatories, the person who makes the answers signs them under oath, and the attorney who objects signs the objections (Rule 33(b)(1), (b)(3), (b)(5)). Collecting information from a client is not itself a sworn verification.

Do not carry the oath over to the other request types. Rule 36(a)(3) allows the party or its attorney to sign the answer or objection, and the text of Rule 34(b)(2) requires a written response without a parallel oath requirement.

Before anything is served, run a review checklist:

• The client confirms dates, providers and prior-injury facts.
• The attorney checks each objection and each item withheld as protected.
• The team checks the damages arithmetic, request numbering and the records scheduled for production.

Compare every substantive statement in an AI-assisted draft with the client’s information and the original records. A guide to AI discovery response software covers the tools themselves.

5. Supplement when treatment or material facts change

A party who has made a Rule 26(a) disclosure, or responded to an interrogatory, RFP or RFA, must supplement or correct it in a timely manner if it learns that the disclosure or response is materially incomplete or incorrect and the corrective information has not otherwise been made known to the other parties during discovery or in writing, or as the court orders (Rule 26(e)(1)).

Typical triggers are a new treating provider, a corrected wage-loss figure or a later bill. Reserving the right to supplement does not substitute for supplementing.

Supplementation has a limit for admissions. A matter admitted under Rule 36 is conclusively established unless the court, on motion, permits the admission to be withdrawn or amended (Rule 36(b)). A supplemental response alone does not undo it.

State rules

Prepare plaintiff discovery responses with Briefpoint

Briefpoint drafts responses and objections to interrogatories, requests for production and requests for admission. The output is editable in Microsoft Word, and attorneys keep final review before anything is served. For personal injury teams, that is the drafting step described above, offered as discovery software for plaintiff firms and through discovery response and objection drafting.

Client Bridge client collection sends clients plain-language questions through a secure link, so they can answer and upload documents for attorney review. That supports the fact check in step 4. The oath that Rule 33(b)(3) requires is a separate step, and the client’s attorney still reviews every answer before it is served.

Autodoc’s responsive-document matching finds responsive documents, adds page-level Bates citations and builds a Bates-numbered production package for the RFP response. Bates numbers identify individual pages in a production. Attorneys review the final responses and objections before service.

FAQs About Personal Injury Discovery Responses

How do you respond to interrogatories in a personal injury case?

Under federal Rule 33(b)(3)–(5), you answer each interrogatory separately and fully in writing under oath to the extent it is not objected to, state any objection with specificity, and have the client sign the answers and the attorney sign the objections. Before the client signs, check provider names and treatment dates against the records, because the oath covers every answer.

Do I have to disclose my entire medical history in a personal injury case?

Not automatically. Under federal Rule 26(b)(1), discovery covers nonprivileged matter that is relevant to a claim or defense and proportional to the needs of the case, and the cited text sets no universal lookback period. A scope objection under Rule 33(b)(4) must be specific, and a party may seek a protective order for good cause under Rule 26(c)(1).

Who signs personal injury discovery responses?

It depends on the request type. Under federal Rule 33(b)(5), the person who makes the interrogatory answers signs them and the attorney who objects signs the objections. For requests for admission, Rule 36(a)(3) allows the party or its attorney to sign. The text of Rule 34(b)(2) requires a written response but does not prescribe an oath.

Can AI tools draft discovery responses for personal injury cases?

Yes. Briefpoint drafts responses and objections to interrogatories, requests for production and requests for admission. The output is editable in Microsoft Word, and attorneys keep final review. Client Bridge also collects client answers and uploaded documents through a secure link for attorney review. Treat these as drafting and collection functions, not a substitute for reviewing the response.

Can AI pull facts from medical records to answer interrogatories?

Do not assume that document matching includes medical-fact extraction for interrogatory answers. The documented capabilities here are finding responsive documents, adding page-level Bates citations, building a Bates-numbered production package, and drafting responses for attorney review. Those capabilities do not establish automatic extraction of diagnoses, treatment dates or causation from medical records into interrogatory answers.
