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.

Response Deadline: Pursuant to Wis. Stat. Section 804.08(1), Defendant must serve a copy of the answers and any objections within thirty (30) days after service of these Interrogatories. If Defendant was served with the Summons and Complaint contemporaneously with these Interrogatories, Defendant may serve answers or objections within forty-five (45) days after service of the Summons and Complaint upon Defendant.

Interrogatory Limit: Under Wis. Stat. Section 804.08(1), each party is limited to twenty-five (25) interrogatories, including all subparts, unless otherwise stipulated by the parties or ordered by the court in a manner consistent with Wis. Stat. Section 804.01(2). Wisconsin law permits only one set of interrogatories per party unless leave of court is obtained.

Continuing Duty to Supplement: Pursuant to Wis. Stat. Section 804.01(6), Defendant has a continuing duty to seasonably amend or supplement any response to these Interrogatories if Defendant obtains information upon the basis of which the response was incorrect when made, or the response, though correct when made, is no longer true and the circumstances are such that failure to amend the response is in substance a knowing concealment.

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

INSTRUCTIONS

1. Separate Answers Required. Each Interrogatory must be answered separately and fully in writing under oath. Restate each Interrogatory in full immediately before the corresponding answer. Pursuant to Wis. Stat. Section 804.08(1), each interrogatory shall be answered separately and fully in writing under oath, unless it is objected to, in which event the reasons for objection shall be stated in lieu of an answer.

2. Oath Requirement. All answers must be signed under oath by the party answering these Interrogatories — not merely by counsel. The answers are to be signed by the person making them, and the objections signed by the attorney making them. Wis. Stat. Section 804.08(1).

3. Privilege Log. If any information is withheld based on a claim of attorney-client privilege, work-product protection, or any other privilege or immunity, Defendant must produce a privilege log identifying the nature of the document, the author, recipient, date, and basis for the claim of privilege, sufficient to enable other parties to assess the claim, consistent with Wisconsin discovery rules.

PRACTICE NOTES

Wisconsin-Specific Discovery Rules

1. Interrogatory Limit. Wis. Stat. Section 804.08(1) limits each party to 25 interrogatories, including all subparts, unless the parties stipulate or the court orders otherwise in a manner consistent with Wis. Stat. Section 804.01(2). This is one of the more restrictive limits among U.S. states. Each discrete subpart (e.g., "(a)," "(b)," "(c)") counts as a separate interrogatory toward the 25-interrogatory cap.

2. One Set of Interrogatories. Wisconsin generally limits each party to one set of interrogatories unless leave of court or stipulation of the parties allows additional sets. Plan interrogatories carefully to maximize the single opportunity.

3. Response Deadline. Answers and objections must be served within 30 days after service. A defendant served with the summons and complaint has 45 days. Wis. Stat. Section 804.08(1).

4. Objection Procedures. Objections must state the specific reasons for the objection. Under Wisconsin practice, boilerplate or generalized objections are disfavored. The objections must be signed by the attorney.

5. Motion to Compel. Under Wis. Stat. Section 804.12(1), if a party fails to answer an interrogatory, the propounding party may move for an order compelling answers. The motion should include a statement of efforts made to resolve the dispute without court intervention.

6. 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

7. 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.

8. ESI Discovery. Wis. Stat. Section 804.09(2m) addresses electronically stored information. When ESI is at issue, coordinate with opposing counsel regarding format, search protocols, and metadata to minimize disputes.

9. Commercial Court Docket. If the case is assigned to a Wisconsin Commercial Court Docket, review the Standard Discovery Protocol for any modifications to standard discovery procedures, including interrogatory limits and timelines.

About This Template

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.

Important Notice

This template is provided for informational purposes. It is not legal advice. We recommend having an attorney review any legal document before signing, especially for high-value or complex matters.
