Full Text of Section 804.11
Plain-English Summary
A request for admission asks the other side to concede something rather than fight about it, and Section 804.11 sets out how that works. A party can serve a written request asking another party to admit the truth of statements or opinions of fact, the application of law to fact, or the genuineness of a document, so long as the request stays within the scope of discovery under Section 804.01(2) and is limited to the pending action.
Each matter has to be admitted or answered separately. The matter is deemed admitted unless the responding party serves a written answer or objection within 30 days, or 45 days for a defendant measured from service of the summons and complaint. A denial has to meet the substance of what was asked, and a party who can admit only part of a request in good conscience has to specify what is true and qualify or deny the rest. A party cannot claim ignorance as an excuse for not admitting or denying unless it states it made a reasonable inquiry and that the information available is still not enough to answer. Notably, a party cannot object to a request just because answering it would resolve an issue that ought to go to trial; the rule requires a denial or an explanation instead. If the requesting party thinks the answers or objections fall short, it can move the court to rule on their sufficiency.
Once a matter is admitted, Section 804.11(2) treats it as conclusively established, unless the court permits it to be withdrawn or amended. The court allows that when doing so would help the case be decided on its merits and the party who got the admission cannot show it would be prejudiced in maintaining its claim or defense. Whatever gets admitted matters only in the case where it was requested; it is not an admission for any other purpose and cannot be used against the party in a separate proceeding.
Frequently Asked Questions
What happens if I do not respond to a request for admission in time?
The matter is deemed admitted. Section 804.11(1)(b) gives a party 30 days to serve a written answer or objection, or 45 days for a defendant measured from service of the summons and complaint, and treats the matter as admitted if that deadline passes without a response.
Can I object to a request for admission just because it touches a disputed issue in the case?
No. Section 804.11(1)(b) says a party who thinks a requested admission presents a genuine issue for trial may not object on that ground alone; the party has to deny the matter or explain why it cannot be admitted or denied.
Can admissions I make under this section be used against me in a different lawsuit?
No. Section 804.11(2) says any admission made under this section is for the purposes of the pending action only, is not an admission for any other purpose, and cannot be used against the party in any other proceeding.
Can I take back an admission I made by mistake?
Yes, if the court agrees. Section 804.11(2) lets the court permit withdrawal or amendment when doing so serves the presentation of the merits and the party who obtained the admission fails to show that withdrawing it would prejudice that party in maintaining its claim or defense.
Do I have to admit or deny a request even if I am not sure of the answer?
You cannot rely on a lack of information alone. Section 804.11(1)(b) requires you to state that you made a reasonable inquiry and that the information known or readily available is still not enough to let you admit or deny.
Amendment History
History: Sup. Ct. Order, 67 Wis. 2d 585, 682 (1975); 1975 c. 218; 1977 c. 447 s. 210; 1983 a. 192; Sup. Ct. Order No. 95-04, 191 Wis. 2d, xxi (1995); 1997 a. 133. The trial court erred in ruling that requests for admissions were limited to matters not denied in the pleadings. Schmid v. Olsen, 111 Wis. 2d 228, 330 N.W.2d 547 (1983). Summary judgment can be based upon a party’s failure to respond to a request for admissions, even if an admission would be dispositive of the entire case. Bank of Two Rivers v. Zimmer, 112 Wis. 2d 624, 334 N.W.2d 230 (1983). A negligence claim’s total value was not a proper subject of a request for admission. Kettner v. Milwaukee Mutual Insurance Co., 146 Wis. 2d 636, 431 N.W.2d 737 (Ct. App. 1988). A court may permit withdrawal of admissions if both statutory conditions under sub. (2) are met, but it is not required to do so. A court may consider a party’s history of discovery abuse when deciding whether to permit withdrawal or amendment of admissions, when determining prejudice under sub. (2), and when otherwise exercising the court’s authority to control the orderly and prompt processing of a case. Mucek v. Nationwide Communications, Inc., 2002 WI App 60, 252 Wis. 2d 426, 643 N.W.2d 98, 00-3039. The prejudice contemplated by sub. (2) is not simply that a party obtaining the admissions would be worse off without the admissions. Prejudice in maintaining the action or defense on the merits relates to the difficulty a party may face in proving its case, e.g., caused by the unavailability of key witnesses, because of the sudden need to obtain evidence with respect to the questions previously answered by the admis- sions. The fact that a trial must be adjourned, or that the time for discovery must be enlarged, does not necessarily mean that the non-moving party will suffer prejudice in maintaining the action or defense on the merits. A party will not be prejudiced in maintaining a defense on the merits if the party is placed in the same position the party would have been in had the admissions not been mistakenly made. Luckett v. Bodner, 2009 WI 68, 318 Wis. 2d 423, 769 N.W.2d 504, 07-0308. It is the burden of the party obtaining the admissions to demonstrate that withdrawal or amendment of the admissions will prejudice that party in maintaining the party’s defense on the merits. Under sub. (2), excusable neglect is not a prerequisite for withdrawal or amendment of an admission. A court must consider the effect upon the litigation and prejudice to the resisting party, rather than focusing on the moving party’s excuses for an erroneous admission. Luckett v. Bodner, 2009 WI 68, 318 Wis. 2d 423, 769 N.W.2d 504, 07-0308. Requests for Admission in Wisconsin Procedure: Civil Litigation’s DoubleEdged Sword. Kinsler. 78 MLR 625 (1995).
