When your client is served with interrogatories, the response is where the case is won or lost. A strong answer raises the right objections, ties every fact to the record, and reserves the plaintiff’s rights as discovery continues. This page shows what a strong interrogatory response looks like and gives you a downloadable sample: a full set of a defendant’s interrogatories with a plaintiff’s strategic answers. As of June 2026, it reflects the format EvenUp’s legal operators use.
Interrogatories are written questions one party sends to another during a lawsuit, answered under oath. Responses to interrogatories, often called ROGs, are the answering party’s sworn replies. In personal injury cases, a defendant serves interrogatories on the plaintiff to establish identity, how the incident occurred, the injuries claimed, the treatment received, and the damages sought.
A few terms are worth knowing. The propounding party is the side sending the interrogatories, the responding party is the side answering, and the verification is the sworn statement confirming the answers are truthful. For the plaintiff’s firm, the work is in the response: answering completely and consistently with the rest of the case file while preserving every available objection.
The downloadable sample is a plaintiff’s answers to a defendant’s first set of interrogatories in an auto-accident case. It walks through eight interrogatories, each with the question as served and a model response, covering:
The sample shows the pattern that separates a strong ROGs response from a boilerplate one. It opens with a general statement preserving objections and the right to supplement, then answers each interrogatory in the same disciplined shape.
That structure is what makes interrogatory answers do double duty: they satisfy the discovery obligation and build the plaintiff’s case at the same time.
Every set follows a predictable structure: a caption identifying the case, a definitions section, instructions for responding, the numbered questions, and a signature block with the sworn verification. The specifics vary by court.
| Element | Federal Court (FRCP Rule 33) | State Court (varies) |
| Question limit | 25, including subparts | Often 25 to 40, some unlimited |
| Response deadline | 30 days | Typically 30 days |
| Format | Written, under oath | Written, under oath |
Knowing the standard objections is what lets a plaintiff’s response protect the record while still answering. The sample raises several of these, each paired with a substantive answer rather than used as a blanket refusal.
| Objection | What it asserts | When it applies |
| Vague or ambiguous | The question is unclear | Imprecise wording or undefined terms |
| Overly broad or unduly burdensome | Answering requires unreasonable effort | No time or scope limit |
| Privileged information | Attorney-client privilege or work product applies | Requests for counsel’s analysis or strategy |
| Seeks legal conclusions | The question asks for analysis, not facts | Fault, negligence, or liability framing |
| Premature or calls for expert opinion | Discovery or expert analysis is ongoing | Permanency and reasonableness of expenses |
| Privacy | The request exceeds what discovery needs | SSNs, driver’s license numbers, third-party data |
Some jurisdictions, California in particular, offer form interrogatories: pre-approved sets courts have already vetted, which makes them harder to object to. Special interrogatories are custom-drafted to a case’s facts, which takes more effort but reaches details a form would miss. Many attorneys use both.
| Type | Best used when | Limitations |
| Form interrogatories | Starting discovery, covering standard issues | May not address case-specific facts |
| Special interrogatories | Exploring unique circumstances, following up | Subject to numerical limits, more likely to draw objections |
Verified answers become powerful tools as a case moves toward trial. Because the client’s responses are signed under oath, keeping them accurate and consistent with the rest of the file is what prevents the defense from using a contradiction for impeachment later. On the other side, the defendant’s answers to your interrogatories lock in their version of events and shape deposition strategy, and an incomplete or evasive defense answer becomes a natural area to press. When the defense’s responses are inadequate, a motion to compel may follow, and courts expect good-faith efforts to resolve disputes informally first, so documenting the attempt matters.
For a plaintiff’s firm, the time sink is the response: a defendant serves interrogatories, and the team has roughly 30 days to answer accurately and consistently across what can be dozens of questions. EvenUp’s ROGs templates are optimized to drive stronger, case-building responses, and AI Drafts generates them from your case files with line-level citations back to the record.
Answers stay consistent with the medical chronology, the demand, and the rest of the file, and the side-by-side view shows exactly which record each fact came from.
I've used other AI tools that were pretty vague, but the level of detail in AI Drafts is great. I also like the side-by-side view where you can reference facts and see exactly which line things are coming from.

A response to interrogatories, often called a ROGs response, is the answering party’s sworn reply to written discovery questions. In a personal injury case, the plaintiff answers each interrogatory under oath, raising any valid objections and tying the answers to the case record. The responses become part of the discovery record and can be used at trial.
Gather the supporting records first, then for each question raise any valid objection (privacy, legal conclusions, premature expert opinion, or work product), and answer subject to and without waiving those objections. Tie every fact to evidence that will be produced, keep answers consistent with the rest of the file, and reserve the right to supplement as treatment and discovery continue.
