A Wisconsin motion in limine is a pretrial request asking the judge to decide whether specific evidence can be used at trial before the jury ever hears it. The ruling happens at the threshold of trial, which is the whole point: once jurors hear something prejudicial, no instruction fully undoes it. Used well, these motions keep the trial focused on evidence that actually belongs there and give both sides clear guidance before opening statements.
Where the Authority Comes From
No Wisconsin statute creates the motion in limine by that name. The authority comes from the trial judge’s general power to manage how evidence is presented. Wisconsin Statute 906.11 directs judges to exercise reasonable control over the questioning of witnesses and the presentation of evidence to get at the truth, avoid wasting time, and protect witnesses from harassment.1Wisconsin State Legislature. Wisconsin Code 906.11 – Mode and Order of Interrogation and Presentation That grant lets courts resolve evidentiary disputes before trial begins.
The second pillar is Wisconsin Statute 904.03, which allows a judge to exclude relevant evidence when its value is substantially outweighed by the risk of unfair prejudice, jury confusion, or wasted time.2Wisconsin State Legislature. Wisconsin Code 904.03 – Exclusion of Relevant Evidence on Grounds of Prejudice, Confusion, or Waste of Time Together, 906.11 and 904.03 back nearly every motion in limine filed in a Wisconsin courtroom.
What These Motions Typically Target
A motion in limine can address almost any evidentiary issue, but a few categories come up over and over.
Prior Bad Acts and Character Evidence
Evidence of a party’s or witness’s prior crimes, bad behavior, or character traits is a frequent target. Wisconsin Statute 904.04 sets the general rule: you cannot introduce someone’s character or past conduct simply to argue they acted the same way this time.3Wisconsin State Legislature. Wisconsin Statutes 904.04 – Character Evidence Not Admissible to Prove Conduct; Exceptions; Other Crimes The statute does carve out exceptions. Prior acts can come in to show motive, intent, identity, plan, or absence of mistake, among other purposes. A well-drafted motion forces the opposing side to name the exception rather than letting the evidence drift in unchallenged.
Liability Insurance
In personal injury and negligence cases, a motion in limine routinely seeks to bar any mention that a party carried liability insurance. Wisconsin Statute 904.11 is clear: evidence that someone was or was not insured is not admissible on the question of whether they acted negligently or wrongfully.4Wisconsin State Legislature. Wisconsin Code 904.11 – Liability Insurance Insurance evidence is admissible only for narrow purposes such as proving agency, ownership, or a witness’s bias.
Expert Testimony
Challenges to expert witnesses are another staple. Under Wisconsin Statute 907.02, an expert can testify only if their specialized knowledge will help the jury, they are properly qualified, their testimony rests on sufficient facts and reliable methods, and they have applied those methods correctly to the case at hand.5Wisconsin State Legislature. Wisconsin Statutes 907.02 – Testimony by Experts A motion in limine aimed at an expert argues that one or more of these requirements is missing.
Prejudicial or Cumulative Evidence
Beyond specific categories, motions often invoke the balancing test in Statute 904.03 to keep out evidence that technically qualifies as relevant but would do more harm than good. Graphic photographs, inflammatory social media posts, and repetitive testimony covering the same ground from multiple witnesses are all fair game.
How to File a Motion in Limine
The motion follows the same basic format as any other motion in Wisconsin practice: a notice of motion, a supporting affidavit when needed, and a brief laying out the legal argument. The brief should cite the specific Wisconsin evidentiary rule or case law that supports exclusion and identify the exact evidence you want the court to address.
Specificity matters. Vague requests to exclude “all prejudicial evidence” accomplish nothing. Name the witness, the document, or the topic, and explain precisely why the jury should not hear it. In many cases, parties collect all of their motions in limine into a single filing with each issue raised in a separately numbered paragraph.
Timing varies by judge and by court. Some judges handle these motions at the final pretrial conference. Others set a separate hearing date or use the court’s standard motion-scheduling calendar. The court’s scheduling order usually sets the deadline. A representative approach requires motions in limine to be filed at least 14 days before the final pretrial conference, with responses due at least 7 days before. Whatever the local practice, file early enough that the judge can actually consider the issue rather than being forced into a snap decision on the morning of trial. The motion and supporting brief must be served on all opposing parties.
How the Court Rules
Most rulings come from reviewing the written submissions, sometimes supplemented by oral argument at the pretrial conference. Evidentiary hearings on motions in limine are uncommon. The judge generally has two paths.
Definitive Rulings
A definitive ruling settles the issue before trial. If the judge definitively excludes evidence, the opposing side may not reference it during any phase of trial, from opening statements through closing arguments. If the judge definitively admits it, the opposing side knows to prepare accordingly. This gives both parties the clearest guidance for trial preparation.
Deferred Rulings
Judges frequently defer ruling until the evidence comes up at trial. This happens when admissibility depends on context the judge cannot fully evaluate from pretrial papers. When a ruling is deferred, the party offering the evidence should alert the judge before presenting it so the admissibility question can be resolved outside the jury’s hearing.6Wisconsin State Legislature. Wisconsin Code 901.03 – Rulings on Evidence Even without a pretrial ruling, the motion still provides value: it puts the court on notice and creates a mechanism for addressing the issue before the jury hears anything questionable.
What Happens When a Party Violates a Ruling
When a judge grants a motion in limine and a party disregards the ruling, the consequences range from embarrassing to case-ending. The court can issue a curative instruction telling the jury to disregard what they heard, though experienced trial lawyers know such instructions often highlight the very thing you wanted hidden. If the violation is serious enough, the court can declare a mistrial and assess the costs of the aborted trial against the offending attorney. In extreme cases, the court may hold the violating lawyer in contempt. A violation can also trigger a referral for professional discipline. Appellate courts review the trial court’s handling of these violations under a deferential standard.
Preserving the Issue for Appeal
Filing a motion in limine is not the end of the story. If you lose the motion and the evidence comes in at trial, or if you win the motion and the judge later reverses course, specific steps are needed to preserve the issue for appellate review. This is where practitioners trip up most often.
When Your Motion to Exclude Is Denied
Wisconsin case law holds that a party who raised a motion in limine generally preserves the right to appeal without also objecting at trial. But that principle comes with a caveat: the issue on appeal must match the issue raised in the motion. If the evidence comes in at trial in a form or context different from what the motion addressed, failure to object at that point may result in waiver. The safer approach is to renew your objection on the record when the evidence is about to come in, done outside the jury’s presence to avoid drawing attention to the material you want excluded.
When Your Evidence Is Excluded
If the court excludes your evidence, Wisconsin Statute 901.03 requires an offer of proof to preserve the issue for appeal. You must ensure the substance of the excluded evidence is made known to the judge, either through a formal offer or because the substance is apparent from the context of the questions being asked.6Wisconsin State Legislature. Wisconsin Code 901.03 – Rulings on Evidence Without an offer of proof, an appellate court has no way to evaluate whether the exclusion actually mattered. The judge can also direct that the offer be made in question-and-answer form for a more complete record.
In jury trials, offers of proof must be handled outside the jury’s presence. The statute specifically requires that proceedings be conducted so that inadmissible evidence is not suggested to the jury through statements, offers of proof, or questions asked within their hearing.6Wisconsin State Legislature. Wisconsin Code 901.03 – Rulings on Evidence
Make the Objection Specific
Statute 901.03 also requires that when evidence is admitted over your objection, the objection must state the specific ground unless the reason is obvious from context.6Wisconsin State Legislature. Wisconsin Code 901.03 – Rulings on Evidence A general objection that something is “inadmissible” usually will not cut it on appeal. The appellate court looks at whether a substantial right was affected by the erroneous ruling, and vague objections make that showing much harder. One narrow safety valve exists: plain errors affecting substantial rights can be noticed on appeal even if no one raised them at trial. Relying on that exception is a gamble no careful practitioner takes voluntarily.
