Wisconsin Civil Discovery Rules and Procedures
Wisconsin discovery is governed primarily by Wis. Stat. § 804.01 et seq. and the Wisconsin Evidence Code (Wis. Stat. § 901 et seq.). Unlike federal practice under the Federal Rules of Civil Procedure, Wisconsin has its own distinct discovery framework with specific numerical limits, timing requirements, and procedural nuances that practitioners must understand.
Mandatory Initial Disclosures
Wisconsin does not require mandatory initial disclosures comparable to Federal Rule 26(a). There is no blanket requirement to automatically provide opponent with contact information, insurance details, or initial witness lists before being asked.
However, Wis. Stat. § 804.01(2) requires parties to supplement responses to discovery requests, and some discovery requests (particularly interrogatories about experts and contentions) will necessarily elicit disclosure of key information early in litigation. Additionally, specific discovery requests can and should be used strategically to obtain foundational information early.
Practical note: Many Wisconsin practitioners use an "early exchange of information" agreement to streamline discovery similar to federal practice, but this is contractual rather than mandatory.
Interrogatories
Numerical Limits and Subparts
Wis. Stat. § 804.01(3) limits interrogatories strictly:
25 interrogatories (including all subparts and discrete questions within a single numbered interrogatory)Additional interrogatories may be served only with written stipulation of the parties or court orderSubparts count toward the limit — this is a critical distinctionFor example, "Identify all documents related to X" followed by "(a), (b), (c)" = multiple interrogatories for limit purposes.
Format and Numbering
Interrogatories must be numbered consecutivelyEach must be capable of being answered separatelyComplex or compound interrogatories are vulnerable to objections under § 804.01(3)Time to Respond
Wis. Stat. § 804.01(3) provides 20 days from service to respond. Requests for extension should be sought in writing before the deadline passes.
Objections and Responses
Objections must be stated with specificity — blanket objections ("burdensome," "overly broad") are disfavoredEven if objection is stated, responding party should provide whatever information is not objectionableBoilerplate objections without particularized explanation are vulnerable to motions to compelIf a party objects, that objection is waivable if not timely assertedRequests for Production of Documents
Scope and Rules
Wis. Stat. § 804.01(5) governs document production:
Requests must describe items with reasonable particularityReceiver must respond within 20 days of serviceDocuments must be produced as kept in the usual course of business, or organized and labeled to correspond with request categoriesElectronically Stored Information (ESI)
Wisconsin courts increasingly address ESI under § 804.01(5). Key principles:
Scope: ESI is discoverable on the same basis as paper documentsFormat: A party should produce ESI in native format if practicable; if not, in TIFF or PDF with metadata preserved, unless parties stipulate otherwiseMetadata: Generally producible unless privileged or protectedCost allocation: Requesting party normally bears cost of retrieval unless voluminous or unduly burdensomePreservation: A party aware of anticipated litigation must preserve relevant ESI; failure creates duty to mitigate damages through adverse inferences or sanctionsWisconsin does not have a specific safe harbor for ESI inadvertently produced (unlike Federal Rule 502(b)), so be cautious.
Clawback Agreements
Wisconsin practitioners frequently enter stipulated "claw-back" or "quick peek" agreements allowing inadvertent review of privileged materials without waiver. While not mandated by statute, courts are receptive to these agreements when properly memorialized.
Requests for Admission
Numerical Limits
Wis. Stat. § 804.01(6) limits requests for admission:
25 requests (counting subparts similarly to interrogatories)Additional requests require written stipulation or court orderTime to Respond
20 days from service to respond (Wis. Stat. § 804.01(6)).
Deemed Admissions
Critical consequence: If a request for admission is not answered within 20 days, it is deemed admitted under § 804.01(6). No "relation back" or after-the-fact denial is permitted except:
Party shows good cause for failure to respondResponse was mailed before deadline (even if received after)Court permits withdrawal of admission for good cause under § 804.01(6)Withdrawal is possible but judges scrutinize late attempts, particularly if opposing party relied on the admission.
Objections
Objections must state reason with specificity. Statements like "not relevant" or "burdensome" without elaboration are insufficient. If objection is taken, responding party should still admit or deny to extent not objectionable.
Depositions
Limits on Number
Wis. Stat. § 804.02 does not impose a numerical limit on depositions (unlike federal practice, which limits to 10 per side). This provides Wisconsin parties greater flexibility, though abuse can be addressed through protective orders or sanctions.
Duration Limits
Default: 4 hours per deponent per dayException: Parties may stipulate to extended duration or court may permit longer depositions for good causeTranscription may continue beyond 4 hours, but examination is ordinarily limited to 4 hoursNotice Requirements
Wis. Stat. § 804.02 requires:
14 days' written notice of deposition (can be reduced or waived by written stipulation)Notice must include date, time, location, and name/description of deponentService on all parties (unless stipulated otherwise)For non-party witnesses: subpoena required (see below)Who Can Be Deposed
Parties and agents of partiesNon-party witnesses (via subpoena)Corporate representatives (must be noticed with sufficient particularity under § 804.02)Use at Trial
Depositions may be used:
For impeachment of trial testimonyAdmissions by opposing partyFor any purpose if witness is unavailable (defined as death, distance >100 miles, infirmity, or other good cause)With parties' stipulationAbsent exception, deposition testimony is not admissible as a substitute for trial testimony if witness is available to testify.
Physical and Mental Examinations
When Allowed
Wis. Stat. § 804.04 permits physical and mental examinations:
Only when condition is "in controversy"Requires court order (or written stipulation between parties)Proponent must demonstrate good causeWho Can Request
Any party may move for order requiring examinationExamined party has right to obtain and retain copy of reportRequirements
"In controversy" standard: Claim or defense must place physical or mental condition directly at issue (not merely incidental)Good cause: Court must find compelling need for examinationLimitations: Court may limit scope, methodology, and frequency to avoid unreasonable burdenExample: In personal injury case, plaintiff's medical condition is in controversy; examining physician may take broad range of examinations. In negligence case where plaintiff's emotional distress is not major claim element, defense may have difficulty obtaining mental examination.
Subpoenas for Non-Parties
Issuance
Wis. Stat. § 804.05 governs non-party subpoenas:
Issued by clerk of court or attorney (with court restrictions in some counties)Must state name and address of issuing attorney/partyMust specify documents or testimony required with reasonable particularityMust provide 14 days' notice before compliance date (reduced notice permitted for good cause)Geographic Limits
Wisconsin: Non-party resident anywhere in state may be subpoenaedOut-of-state: Non-party may be subpoenaed only if resident of Wisconsin for 30 days or more, or employed within state, or doing business within stateOut-of-state depositions: Limited by reciprocal arrangements; federal court subpoena rules (100-mile bulge) do not apply to state courtCompliance Requirements
Non-party must comply unless grounds for quashing existGrounds for quashing: privilege, undue burden, lack of notice, witness subpoenaed to testify outside reasonable geographic area (§ 804.05(4))Non-party may seek protective order or motion to quashExpert Discovery
Disclosure Requirements
Wis. Stat. § 804.01(9) requires:
Identification of experts early — typically via interrogatory responseExpert report or statement: While not mandatorily required like federal practice, good practice is to provide report containing: - Expert's qualifications
- Summary of opinions
- Facts and assumptions relied upon
- Bases for opinions
Timing
Disclosure window: Should occur early, typically 60-90 days before trial (no statutory mandate, but discovery cutoff rules apply)Reciprocal: Opposing party has opportunity to designate rebuttal expertsDeposing Experts
Expert depositions permitted under § 804.02 (no distinct limitations)Depositions of treating physicians generally permitted; expert consultants (not expected to testify) may be protected if prepared at attorney directionScope of Discovery
What Is Discoverable
Wis. Stat. § 804.01(1) defines scope:
Relevant to subject matter of actionLikely to lead to discovery of admissible evidenceInformation concerning parties, claims, defenses, damagesWisconsin's scope is broader than the federal "proportional to needs" formulation but still not unlimited.
Relevance Standard
Information need not be admissible at trialNeed not be directly material to claim or defense"Likely to lead to" discovery standard permits reasonable inquiry into peripheral mattersProportionality Considerations
While § 804.01 does not explicitly reference proportionality, Wisconsin courts consider proportionality in determining scope:
Burden of production vs. benefit to caseWhether information can be obtained from other sourcesNature and amount of discovery already conductedImportance of information to caseDisproportionate requests may be limited via protective order.
Privileges and Work Product
Attorney-Client Privilege
Wis. Stat. § 905.02 protects communications between attorney and client:
Communication must be made in confidence for purpose of obtaining/providing legal adviceApplies to both in-house counsel and outside counselApplies to documents prepared by attorney at client directionWork Product Doctrine
Wis. Stat. § 804.01(4) provides qualified immunity for work product:
Materials prepared by attorney in anticipation of litigationIncludes attorney's mental impressions, conclusions, opinionsQualified protection (not absolute) — can be overcome by showing: - Substantial need for materials
- Inability to obtain equivalent information by other reasonable means
- Examination of expert work product requires showing of exceptional circumstances
Privilege Logs
While not statutorily required, Wisconsin practice expects privilege logs when privilege is asserted:
Document should be listed with date, author, recipient, subject matterPrivilege asserted (attorney-client, work product, etc.)Brief explanation of basisFailure to log may result in waiver or adverse inference.
Meet and Confer Requirements
Wis. Stat. § 804.01 does not explicitly mandate meet-and-confer before filing discovery motions. However, Wisconsin courts expect parties to attempt resolution:
Best practice: Written request for response before filing motion to compelAffidavit of effort to resolve should accompany motion to compelCourt may impose sanctions on party filing motion without reasonable effort to conferDiscovery Cutoffs
Timing Relative to Trial
Wisconsin does not have a bright-line discovery cutoff rule in the statutes. However:
Default deadline: Discovery ordinarily closes 60-90 days before trial (local rules vary by county; refer to individual county circuit court rules)Trial court discretion: Judge may extend or curtail discovery timing by order or standing orderLate discovery: Strict application of discovery deadlines is typical; late requests are often denied absent good causeProtective Orders
Obtaining Protective Orders
Wis. Stat. § 804.01(8) permits protective orders upon motion:
Party may move for order protecting against harassment, burden, or expenseCourt may: - Deny discovery
- Require limited scope
- Specify conditions (e.g., attorney's eyes only, protective agreement)
- Require phased discovery
- Impose other conditions
Good Cause Standard
Good cause required:
Burden or expense significantly outweighs likely benefitInformation is sensitive, confidential, or proprietaryBroad categories: trade secrets, financial information, personnel files, medical recordsCommon protective orders:
Stipulated confidentiality agreements (most common; parties agree not to disclose)Counsel only designationsRestricted access to specific individualsRedaction of sensitive portionsMotions to Compel
Procedure
Wis. Stat. § 804.01(7) establishes motion to compel process:
Must include certification of effort to resolve disputeServed on resisting partyCourt may order compliance or hold hearingCourt may award expenses if motion granted (see below)Burden of Proof
Initial burden on requesting party: Show that discovery request is proper, timely, and compliant with § 804.01Burden shifts to resisting party: Once properness shown, resisting party must prove objection is validBoilerplate objections insufficient; particularized showing requiredFees and Expenses
Wis. Stat. § 804.01(7) provides:
Court may require resisting party to pay reasonable expenses, including attorney fees, if motion grantedException: If resisting party's position substantially justified, fees not awardedBurden is on requesting party to show lack of substantial justificationSanctions for Discovery Abuse
Wisconsin Sanctions Rules
Wis. Stat. § 804.12 governs sanctions for discovery violations:
Types of sanctions:
Monetary: Reasonable expenses and attorney feesNon-monetary: Preclusion of evidence, judgment by default, dismissal, contemptSpecific Violations Triggering Sanctions
Failure to respond to discoveryProviding false or incomplete responseFailure to preserve ESI (adverse inference or sanctions)Violation of protective orderDeposition abuse (e.g., obstruction, coaching)Judicial Discretion
Judges have broad discretion in fashioning sanctions. Courts require:
Showing of prejudice: How was opposing party harmed?Willfulness: Was violation intentional or negligent?Prior warnings: Have parties been warned?Proportionality: Is sanction proportionate to violation?Contempt sanctions (especially preclusion or default) require clear and convincing evidence of violation.
Adverse Inferences
Courts frequently impose adverse inferences rather than drastic sanctions:
If party destroys or fails to preserve ESI, jury may infer content was unfavorableRequires showing that information was relevant and party knew litigation was anticipatedUnique Wisconsin-Specific Practices
Local Rules and County Variations
Wisconsin has no uniform statewide discovery rules beyond statutesIndividual counties have local rules (e.g., Dane County Circuit Court, Milwaukee County) specifying: - Discovery deadlines
- Standing orders on ESI format
- Mediation/conference requirements
Always check applicable county local rules before initiating discoveryStipulated Protective Agreements
Wisconsin practice heavily favors stipulated discovery agreements to streamline process:
Parties often stipulate to: - Extended discovery periods
- Increased interrogatory/request limits
- Expedited expert exchange
- ESI protocols
Written stipulation binds parties and avoids motion practicePractical Wisconsin Considerations
Rural counties: Longer distances may affect deposition logistics and witness availabilityJudicial economy: Wisconsin judges emphasize proportionality and discourage "scorched earth" discoveryEarly settlement conferences: Many counties require early mediation/settlement conference, which affects discovery timing---
Key Takeaways
No mandatory initial disclosures in Wisconsin; discovery is request-based, but interrogatories and expert questions will elicit early substantive information25-interrogatory and 25-request limits (including subparts) apply unless parties stipulate or court orders otherwise; these are strictly enforced20-day response deadline applies to interrogatories, requests for production, and requests for admission; failure to respond to admissions results in deemed admissions absent good causeNo numerical limit on depositions but 4-hour default duration applies; 14 days' notice required and must-respond timing is strictESI production rules are evolving but generally require native format
