In federal court, when to file a motion in limine is controlled by the judge’s scheduling order, the court’s local rules, or the judge’s standing orders, and most deadlines fall somewhere between 5 and 30 days before the final pretrial conference or the trial date. Miss that date and the court can treat the motion as waived, letting the evidence come in without a pretrial ruling.
Where Your Deadline Actually Comes From
Start with the scheduling order. Federal Rule of Civil Procedure 16 requires judges to issue one early in the case, and that order must set a deadline for filing motions.1Legal Information Institute. Federal Rules of Civil Procedure Rule 16 – Pretrial Conferences; Scheduling; Management If the scheduling order says motions in limine are due 14 days before the pretrial conference, that is your deadline, regardless of what any other rule says. The scheduling order is tailored to your case and overrides default timelines.
When the scheduling order is silent on motions in limine, check the court’s local rules and then the individual judge’s standing orders. Many federal judges publish their own procedural requirements specifying when these motions must be filed and when responses are due. The timeframes vary widely. Some judges require filing at least 10 days before the pretrial conference. Others allow filing up to 5 working days before trial.
In criminal cases, if neither the scheduling order nor local rules set a deadline, the default under Federal Rule of Criminal Procedure 12 is the start of trial, though the court can set an earlier deadline at arraignment or any time afterward.2Legal Information Institute.

What a Late Filing Costs You
Filing late is not a minor procedural slip. In criminal cases, Rule 12 is explicit: an untimely motion is treated as waived unless the party shows good cause for the delay.2Legal Information Institute. Federal Rules of Criminal Procedure Rule 12 – Pleadings and Pretrial Motions In civil cases, modifying a scheduling order deadline requires good cause under Rule 16(b)(4), which is a higher bar than many attorneys expect.1Legal Information Institute. Federal Rules of Civil Procedure Rule 16 – Pretrial Conferences; Scheduling; Management Being busy or not realizing you needed the motion earlier will not clear that bar.
The practical cost is that prejudicial evidence reaches the jury without an advance ruling to block it. You can still object at trial, but you lose the strategic advantage of resolving the issue beforehand. If the court treats the issue as waived, you may have no objection to make at all.
The Meet and Confer Step Before Filing
Many courts require opposing counsel to discuss anticipated evidentiary disputes informally before any motion in limine is filed. This “meet and confer” obligation appears in the local rules of a large number of federal district courts, and some judges refuse to hear a motion unless counsel certifies the discussion took place. Build that conversation into your pre-filing timeline so it does not push you up against the filing deadline itself.
Even where no local rule requires it, the step is worth doing. Your opponent may stipulate to excluding certain evidence without a fight, saving you the time and expense of briefing a motion the court would rather not read.
Strategic Timing Within the Deadline
Within whatever deadline applies, you have real discretion about when to file, and that choice matters.
Filing Early
Filing early, sometimes before discovery is complete, lets you shape the case. If the court excludes a category of evidence, there may be no reason to spend time and money exploring that topic in depositions. An early favorable ruling can also shift settlement dynamics. When the other side loses a key piece of evidence, the case looks different and settlement offers tend to reflect that.
Filing Closer to Trial
Filing later has different advantages. By then you have seen all the evidence, read every deposition transcript, and reviewed the other side’s exhibit list. Your motion can target exactly what your opponent plans to use at trial, with precise citations to the record. A well-supported motion filed on a complete record is generally more persuasive than a speculative one filed early. Motions involving expert witnesses, for example, are typically filed after the close of discovery because the full expert report and deposition are needed to challenge the testimony effectively.
The Middle Path
For most cases, the strongest approach is to file early enough to get a ruling before trial but late enough that the motion rests on a complete factual record. Filing at the last possible moment within the deadline is risky because it leaves no margin if the court orders supplemental briefing or if you need to revise after seeing the opposition’s response.
Why Timing Still Matters After the Ruling
A ruling on a motion in limine is interlocutory. It can be revisited as the trial unfolds. The Supreme Court made this clear in Luce v. United States, noting that an in limine ruling “is subject to change when the case unfolds, particularly if the actual testimony differs from what was contained in the defendant’s proffer,” and that a judge remains free to alter a previous ruling in the exercise of sound discretion.3Legal Information Institute. Luce v. United States A denial does not guarantee the evidence will come in, and a grant does not guarantee it stays out.
That flexibility feeds back into timing. If you won a favorable ruling pretrial, the other side can ask the judge to reconsider once trial is underway and the factual picture has changed. If your motion was denied, you may get a second chance to object when the evidence is actually offered.
Preserving the Issue for Appeal
Timing also matters for appeal. Federal Rule of Evidence 103 governs preservation. If the court admits evidence over your objection, you must have made a timely objection on the record stating the specific ground. If the court excludes your evidence, you must make an offer of proof so the appellate court knows what the jury would have heard.4Legal Information Institute. Federal Rules of Evidence Rule 103 – Rulings on Evidence
Rule 103(b) provides that once a court rules “definitively on the record,” a party does not need to renew the objection at trial to preserve it.4Legal Information Institute. Federal Rules of Evidence Rule 103 – Rulings on Evidence What counts as “definitive” is not always obvious. The drafters acknowledged the standard is somewhat imprecise. If the judge’s ruling sounds tentative, conditional, or subject to revisiting at trial, it probably is not definitive enough to preserve the issue automatically.
The safest practice is to renew the objection at trial when the evidence is offered, even if you already have a pretrial ruling. It costs nothing and removes ambiguity. In Luce, the Supreme Court held that a defendant who chooses not to testify cannot later challenge an in limine ruling on impeachment with prior convictions, because the reviewing court has no way to assess the impact of the error on a record that never included the defendant’s testimony.3Legal Information Institute. Luce v. United States The lesson extends beyond impeachment. Rulings on motions in limine are preserved most reliably when the issue plays out at trial and the objection appears in the trial record.
