INTRODUCTORY STATEMENT

Plaintiff, [________________________________], by and through undersigned counsel, pursuant to Wisconsin Statutes Chapter 804, propounds the following Interrogatories upon Defendant, [________________________________], to be answered separately, fully, in writing, and under oath.

Count and deadline control. Before service, delete unused requests and subparts so that this party's interrogatories do not exceed the reasonable-number limit of 25, including all subparts, under Wis. Stat. § 804.08(1)(am), unless a stipulation or court order permits more. Enter the cumulative count [DETAILS], any stipulation, order, or local limit [DETAILS], service date and method [DETAILS], and calculated response date [DATE]. Section 804.08(1)(b) generally allows 30 days after service of the interrogatories to answer or object; a defendant may answer or object within 45 days after service of the summons and complaint, and the court may change the period.

Supplementation control. Wis. Stat. § 804.01(5) does not impose a blanket duty to supplement a response complete when made. Its listed exceptions and any applicable order or agreement govern later corrections or updates.


DEFINITIONS

For purposes of these Interrogatories, the following definitions shall apply:

1. "Action" means the above-captioned lawsuit, including all claims, counterclaims, cross-claims, and third-party claims asserted in the pleadings.

2. "Communication" means any manner of transmitting or receiving information, whether oral, written, or electronic, including but not limited to conversations, telephone calls, emails, text messages, letters, memoranda, facsimiles, social media messages, video conferences, and any other form of information exchange.

3. "Document" means any written, printed, typed, recorded, or graphic matter of any kind, however produced or reproduced, including electronically stored information ("ESI"), as broadly defined under Wis. Stat. ch. 804. This includes but is not limited to writings, drawings, graphs, charts, photographs, audio/video recordings, emails, text messages, databases, spreadsheets, metadata, and any other tangible or electronic material.

4. "Describe" means to provide a detailed narrative account including all relevant facts, circumstances, dates, times, locations, and persons involved.

5. "Identify" (when referring to a natural person) means to state the person's name, role in the events at issue, and business or other available contact information relevant to this Action, subject to applicable privacy and protective orders.

6. "Identify" (when referring to an entity) means to state the entity's full legal name, type of entity (corporation, LLC, partnership, etc.), state of formation, principal place of business address, and the name and contact information of a knowledgeable representative or registered agent.

7. "Incident" means the events, transactions, occurrences, or series of events giving rise to the claims and defenses in this litigation as described in the pleadings.

8. "Occurrence" has the same meaning as "Incident" and the terms are used interchangeably.

9. "You," "Your," or "Defendant" means [________________________________], the party served, including information available to that party through an authorized officer or agent, subject to applicable privilege and proportionality limits.

INSTRUCTIONS

1. Separate Answers Required. Under Wis. Stat. § 804.08(1)(b), each interrogatory must be answered separately and fully in writing under oath unless objected to, in which case the reasons for objection are stated in lieu of an answer. Number each answer to match its interrogatory.

Stat. § 804.01(2)(e) does not itself require the listed privilege-log fields.

4. Objections. State the reasons for any objection under Wis. Stat. § 804.08(1)(b). If only part of an Interrogatory is objectionable, answer the remainder to the extent it seeks discoverable information.

5. Sources of Information. When the answer is not solely within Your personal knowledge, state the name of any person possessing such knowledge and the source of the information.

PRACTICE NOTES

Wisconsin-Specific Discovery Rules

1. Interrogatory limit. Wis. Stat. § 804.08(1)(am) limits a party to a reasonable number of requests, no more than 25 interrogatories including all subparts, unless the parties stipulate or the court orders otherwise consistently with § 804.01(2). Count earlier requests and each subpart before serving this form; the statute does not impose a one-set limit.

2. Objection Procedures. Under Wis. Stat. § 804.08(1)(b), state reasons for an objection in place of an answer to the objected-to matter. The attorney making the objection must sign it.

3. Motion to Compel. Under Wis. Stat. § 804.12(1), if a party fails to answer an interrogatory, the propounding party may move on reasonable notice for an order compelling an answer. Check any applicable court order for pre-motion conference requirements.

4. Sanctions. Wis. Stat. Section 804.12(2) authorizes sanctions for failure to comply with a court order compelling discovery, including:

  • ☐ Establishing designated facts as admitted
  • ☐ Refusing to allow the disobedient party to support or oppose claims or defenses
  • ☐ Striking pleadings or parts thereof
  • ☐ Staying proceedings until compliance
  • ☐ Dismissing the action or rendering default judgment
  • ☐ Contempt of court

5. Proportionality. Wis. Stat. Section 804.01(2) requires that discovery be proportional to the needs of the case, considering the importance of the issues at stake, the amount in controversy, the parties' relative access to relevant information, the parties' resources, and whether the burden or expense of proposed discovery outweighs its likely benefit.

6. ESI Discovery. Before serving a § 804.09 request to produce electronically stored information, confer on the subjects, preservation, form, privilege method, and cost under Wis. Stat. § 804.01(2)(e)1r, unless the court excuses that conference. Section 804.09 governs the production request itself.

These are the filings that drive a lawsuit through the system: complaints, answers, motions, briefs, discovery requests and responses, and post-judgment papers. Each has its own format requirements under federal and state procedural rules, and each has a deadline that cannot be missed without consequences. Clean, procedurally correct filings move a case forward; sloppy ones invite motions to strike, amended responses, and avoidable delays.
