A non-dispositive motion is a pretrial request that deals with the procedural mechanics of a lawsuit without resolving any claim on its merits. These motions decide who has to turn over documents, when deadlines fall, what evidence the jury will hear, and how a case moves from filing to trial. They shape the battlefield. They never decide the war.
How It Differs From a Dispositive Motion
The line between the two categories comes down to whether granting the motion could end the case. A dispositive motion asks the judge to resolve some or all of the claims outright. A motion for summary judgment argues that the evidence is so one-sided that no reasonable jury could find for the other party; if the judge agrees, the case ends without trial. A motion to dismiss for failure to state a claim works similarly, knocking out a claim because the complaint doesn’t describe a viable legal theory.
Federal law draws this boundary explicitly. Under 28 U.S.C. § 636, a magistrate judge can handle any pretrial matter except motions for injunctive relief, summary judgment, judgment on the pleadings, dismissal for failure to state a claim, class-action certification, and a handful of criminal-side motions.1Office of the Law Revision Counsel. 28 USC 636 – Jurisdiction, Powers, and Temporary Assignment Everything outside that exclusion list is non-dispositive. The label matters because it determines which judge hears the motion and how hard it is to overturn the ruling later.
Common Types of Non-Dispositive Motions
Some of these come up in nearly every case. Others appear only when specific problems arise.
Motion to Compel Discovery
The workhorse. When one side refuses to answer interrogatories, produce documents, or make a witness available for deposition, the other side can ask the court to force compliance. Federal Rule of Civil Procedure 37(a) covers failures to provide required initial disclosures, answer written questions, produce documents, or permit inspections.2Legal Information Institute. Federal Rules of Civil Procedure Rule 37 – Failure to Make Disclosures or to Cooperate in Discovery; Sanctions Evasive or incomplete responses count the same as outright refusals. If the court grants the motion, the losing side usually pays the winner’s attorney’s fees for bringing it.
Motion for a Protective Order
The flip side of a motion to compel. When a party or witness believes a discovery request is harassing, overly broad, or seeks trade secrets or other confidential information, they can ask the court for protection. Federal Rule 26(c) lets the court limit or prohibit certain discovery, restrict who can attend a deposition, seal confidential material, or impose conditions on how sensitive information is shared. The movant must show good cause and certify they tried to resolve the dispute with the other side before filing.
Motion to Amend Pleadings
Complaints and answers aren’t always right on the first draft. A party can amend once as a matter of right within 21 days of serving the pleading, or within 21 days of receiving either a responsive pleading or a motion under Rule 12.3Legal Information Institute. Federal Rules of Civil Procedure Rule 15 – Amended and Supplemental Pleadings After that window closes, amendment requires either the opposing party’s written consent or the court’s permission. Courts are supposed to grant leave freely “when justice so requires,” but judges weigh factors like delay, prejudice to the other side, and whether the amendment would be futile.
Motion for an Extension of Time
Deadlines in litigation are real, and missing one can be catastrophic. A motion for extension asks the court to push back a filing or procedural deadline. If the request comes before the deadline passes, the court has broad discretion to grant it for good cause. If the deadline has already lapsed, the standard gets tougher: the party must show the delay resulted from excusable neglect.
Motion to Strike
Under Federal Rule 12(f), a party can ask the court to remove material from a pleading that is irrelevant, immaterial, or scandalous.4Legal Information Institute. Federal Rules of Civil Procedure Rule 12 – Defenses and Objections: When and How Presented The court can also strike insufficient defenses. The motion must be filed before responding to the pleading, or within 21 days of service if no response is required. Courts can also strike material on their own initiative. In practice, these motions succeed most often when the challenged material is clearly inflammatory or has no conceivable relevance to the claims.
Motion in Limine
Filed before or at the start of trial, a motion in limine asks the judge to exclude specific evidence before the jury ever hears it. The goal is to keep prejudicial, irrelevant, or inadmissible material from influencing jurors even momentarily. These motions are decided outside the jury’s presence and are a standard part of trial preparation. One caution: if a motion in limine effectively eliminates an entire element of a party’s claim or defense, courts may treat it as dispositive, meaning it has to satisfy the stricter standards governing summary judgment.
Motion to Consolidate
When multiple cases pending before the same court share common questions of law or fact, any party can move to consolidate them under Federal Rule 42(a).5Legal Information Institute. Federal Rules of Civil Procedure Rule 42 – Consolidation; Separate Trials The court can join cases for hearing or trial, fully consolidate them, or issue other orders to cut duplication and cost. Consolidation doesn’t change the legal rights of any party. It just prevents the same witnesses from testifying three separate times about the same car accident.
The Meet-and-Confer Requirement
Before filing most non-dispositive motions in federal court, you have to try to resolve the dispute without court involvement. For discovery motions, Rule 37(a)(1) requires the movant to certify in writing that they attempted in good faith to confer with the other side before filing.2Legal Information Institute. Federal Rules of Civil Procedure Rule 37 – Failure to Make Disclosures or to Cooperate in Discovery; Sanctions Protective-order motions carry the same obligation under Rule 26(c).
Skip this step and the consequences are real. A court can deny the motion outright, and even if it grants the motion, it cannot award attorney’s fees to a party that never tried to work things out first. Many federal districts have local rules that go further than the baseline. Some demand in-person conferences when opposing counsel are in the same county. Others require a telephone call between lead attorneys and explicitly state that exchanging letters or emails does not count. Check local rules before filing.
How to File One
The basic process in federal court involves submitting a written motion to the court and serving a copy on the opposing party. The motion must describe the specific relief you want and include a proposed order for the judge to sign. Supporting memoranda, affidavits, and exhibits can be filed alongside the motion but are not always mandatory.6eCFR. 12 CFR 1081.205 – Non-Dispositive Motions
Under Federal Rule 6(c), written motions and hearing notices generally must be served at least 14 days before the scheduled hearing, unless the rules or a court order set a different timeline.7Legal Information Institute. Federal Rules of Civil Procedure Rule 6 – Computing and Extending Time; Time for Motion Papers The opposing party then files a written response, and the movant may file a reply. Many judges decide non-dispositive motions “on the papers” without a hearing, though a party can request oral argument. Whether the court grants that request is up to the judge.
Who Decides the Motion
In federal court, a district judge can refer non-dispositive pretrial matters to a magistrate judge, who then has full authority to hear and decide them.1Office of the Law Revision Counsel. 28 USC 636 – Jurisdiction, Powers, and Temporary Assignment This delegation is one of the main practical reasons the dispositive/non-dispositive distinction matters. Magistrate judges handle the bulk of pretrial case management in busy districts, and their rulings on non-dispositive matters are immediately binding. When a magistrate judge is assigned a dispositive motion, by contrast, they can only recommend a result. The district judge must then review that recommendation from scratch before issuing a final ruling.8Legal Information Institute. Federal Rules of Civil Procedure Rule 72 – Magistrate Judges: Pretrial Order
Objecting to a Magistrate Judge’s Ruling
If you disagree with a magistrate judge’s order on a non-dispositive matter, you have 14 days after being served to file objections with the district judge assigned to the case.8Legal Information Institute. Federal Rules of Civil Procedure Rule 72 – Magistrate Judges: Pretrial Order The deadline is firm. Miss it, and you generally cannot challenge the ruling later in the case or on appeal. Rule 72(a) says it directly: a party may not raise as error a defect in the order they failed to timely object to.
Even when objections are timely, the standard of review is steep. The district judge will overturn the magistrate’s order only if it is “clearly erroneous or contrary to law.”1Office of the Law Revision Counsel. 28 USC 636 – Jurisdiction, Powers, and Temporary Assignment “Clearly erroneous” means the reviewing judge must have a definite and firm conviction that a mistake was made. Simple disagreement isn’t enough. That’s a much more deferential standard than the de novo review that applies to dispositive matters, and as a practical matter, magistrate judges’ non-dispositive rulings are overturned relatively rarely.
Cost-Shifting and Sanctions
Non-dispositive motions are not free moves. Federal Rule 37(a)(5) creates a default fee-shifting rule for discovery motions that makes the loser pay. If a motion to compel is granted, the court must order the party that forced the motion to pay the movant’s reasonable expenses, including attorney’s fees, unless the opposition was substantially justified or an award would be unjust.2Legal Information Institute. Federal Rules of Civil Procedure Rule 37 – Failure to Make Disclosures or to Cooperate in Discovery; Sanctions The same rule works in reverse: if the motion is denied, the movant may be ordered to pay the other side’s costs for having to respond.
When a motion is partially granted and partially denied, the court can split costs between the parties however it sees fit. This mechanism is meant to discourage both stonewalling on discovery and filing frivolous motions. It also gives the meet-and-confer requirement financial consequences. A party that files a motion to compel without first attempting to resolve the dispute in good faith cannot recover fees even if the motion is granted.
The Scheduling Order Overlay
Most non-dispositive motion practice operates within the framework of the court’s scheduling order, issued under Federal Rule 16. The scheduling order sets deadlines for joining additional parties, amending pleadings, completing discovery, and filing motions.9Legal Information Institute. Federal Rules of Civil Procedure Rule 16 – Pretrial Conferences; Scheduling; Management Once those deadlines are set, modifying them requires showing good cause. A motion to amend a complaint filed after the scheduling order’s amendment deadline faces a higher bar than one filed within the original window.
That creates a second layer of deadlines beyond the ones in the federal rules themselves. The rules might say leave to amend should be freely given, but if you’ve blown past the scheduling order’s cutoff, the judge will ask why you didn’t act sooner. Many non-dispositive motions that fail on the merits actually fail because the party waited too long to bring them.
