A motion for sanctions is a formal request asking a judge to penalize a party, their attorney, or both for misconduct during a lawsuit. It gets filed when one side believes the other has submitted a frivolous filing, hidden or destroyed evidence, violated a court order, or otherwise abused the litigation process. If the judge grants it, the penalty can range from paying the other side’s attorney fees to having the entire case dismissed.
What Conduct Triggers a Sanctions Motion
Sanctions motions tend to grow out of four kinds of behavior, and the rule the motion is filed under usually tracks the conduct.
Frivolous or Bad-Faith Filings
The most common trigger is a filing with no reasonable basis in fact or law. Fabricated claims used to pressure a settlement, legal arguments no competent attorney would advance, or motions filed purely to run up the other side’s bills all qualify. Federal Rule of Civil Procedure 11 requires that every pleading, motion, or other paper filed with a court be supported by a reasonable investigation into the facts and the law, and that it not be filed for an improper purpose like harassment or delay.1Legal Information Institute.

Discovery Abuse
Discovery is the phase where parties exchange documents, answer written questions, and sit for depositions. Refusing to produce documents, giving evasive answers, stonewalling legitimate requests, or disobeying a court order compelling production all fall under Rule 37, which authorizes some of the harshest penalties available in civil litigation.2Legal Information Institute.

Destroying or failing to preserve electronic evidence deserves special mention because it trips up so many litigants. Under Rule 37(e), when electronically stored information that should have been preserved is lost because a party didn’t take reasonable steps to keep it, the court can intervene. If the loss merely prejudices the other side, the judge can order measures to cure that prejudice. If the court finds the party intentionally destroyed the data to keep it out of the case, the penalties jump: the judge can instruct the jury to presume the lost evidence was unfavorable, dismiss the case, or enter a default judgment.2Legal Information Institute.

Violating a Court Order
Ignoring a direct order from a judge is one of the fastest routes to sanctions. Missed court-set deadlines, failure to appear at a scheduled conference, or disregarding a specific directive about how evidence must be handled all count. The system assumes compliance, and judges respond sharply when a party picks which orders to follow.
Delay Tactics and Harassment
Conduct designed to drag out litigation or drive up the other side’s costs can draw sanctions even when no single filing is technically frivolous. Under 28 U.S.C. § 1927, an attorney who unreasonably multiplies proceedings can be ordered to personally pay the excess costs and fees caused by their conduct.3Office of the Law Revision Counsel. 28 U.S. Code 1927 – Counsel’s Liability for Excessive Costs That statute reaches only lawyers and others admitted to practice before the court; it cannot be used against the parties themselves.
Beyond any specific rule, federal courts also hold inherent authority to punish conduct that abuses the judicial process. The Supreme Court has held that a court may shift attorney fees under this power when a party has acted in bad faith, vexatiously, or for oppressive reasons.4Justia U.S. Supreme Court Center. Chambers v. Nasco, Inc., 501 U.S. 32 (1991) Courts are expected to rely on specific rules first and reach for inherent power when those rules aren’t enough.
What a Judge Can Order
Penalties get tailored to the severity of the misconduct. In practice they sit in three tiers.
Monetary Sanctions
The most common sanction is an order to pay money. Under Rule 11, a court can order the offending side to pay part or all of the reasonable attorney fees and expenses the other party incurred as a direct result of the violation.1Legal Information Institute. Federal Rules of Civil Procedure Rule 11 – Signing Pleadings, Motions, and Other Papers; Representations to the Court; Sanctions Under § 1927, an attorney can be ordered to personally cover the excess costs their conduct caused.3Office of the Law Revision Counsel. 28 U.S. Code 1927 – Counsel’s Liability for Excessive Costs When courts invoke inherent power, fee awards must be compensatory rather than punitive, limited to fees that would not have been incurred but for the sanctioned party’s bad-faith conduct.
One important limit: under Rule 11, a court cannot impose monetary sanctions on a represented party for making a frivolous legal argument. That penalty falls on the attorney who signed the filing, not the client.1Legal Information Institute. Federal Rules of Civil Procedure Rule 11 – Signing Pleadings, Motions, and Other Papers; Representations to the Court; Sanctions The client is generally relying on the lawyer’s judgment about whether a theory has merit.
Evidentiary Sanctions
These penalties hit the case itself by limiting what a party can use. A judge can prohibit a party who defied a discovery order from using the withheld evidence to support their claims or defenses. If a party fails to disclose a witness or document required under the discovery rules, they are automatically barred from using that information at trial unless the failure was harmless or substantially justified.2Legal Information Institute. Federal Rules of Civil Procedure Rule 37 – Failure to Make Disclosures or to Cooperate in Discovery; Sanctions
A judge can also direct that certain facts be treated as established. If you were ordered to produce financial records and refused, the court might rule that the amounts the other side claims are accepted as true for purposes of the case.2Legal Information Institute. Federal Rules of Civil Procedure Rule 37 – Failure to Make Disclosures or to Cooperate in Discovery; Sanctions That kind of ruling can quietly decide a case without a formal dismissal.
Case-Ending Sanctions
For the most severe misconduct, a judge can resolve the case outright. Under Rule 37, a court that finds a party defied a discovery order can strike their pleadings, dismiss the lawsuit, enter a default judgment, or treat the violation as contempt of court. Intentional destruction of electronic evidence to deprive the other side of its use can produce the same result under Rule 37(e).2Legal Information Institute. Federal Rules of Civil Procedure Rule 37 – Failure to Make Disclosures or to Cooperate in Discovery; Sanctions These are reserved for cases where lesser measures have failed or the conduct is so extreme that nothing else fits. Rule 11 sanctions, by contrast, must be limited to what is needed to deter the behavior, so a court looking for the heaviest penalties typically turns to Rule 37 or its inherent power.1Legal Information Institute.

How the Motion Gets Filed
A Rule 11 motion for sanctions must be filed separately from any other motion and must describe the specific conduct that violated the rule. Before filing it with the court, the moving party must serve the motion on the opposing side and wait 21 days. This “safe harbor” period lets the accused party withdraw the offending filing or correct the problem. If they do, the motion cannot be filed at all.1Legal Information Institute. Federal Rules of Civil Procedure Rule 11 – Signing Pleadings, Motions, and Other Papers; Representations to the Court; Sanctions Plenty of sanctions disputes end there. The threat alone prompts a correction, and both sides avoid the cost and risk of a contested motion.
If the safe harbor period passes without a fix, the motion goes to the court. The accused party then has a set period to file a written response. The judge may schedule a hearing for oral argument before issuing a written ruling. A sanctions order must describe the conduct that justified the penalty and explain the basis for the sanction imposed.1Legal Information Institute.

A judge doesn’t always need a motion to start the process. Under Rule 11, a court can act on its own by ordering an attorney, law firm, or party to explain why their conduct should not be treated as a violation. The target still gets notice and a reasonable opportunity to respond before any penalty is imposed.1Legal Information Institute.

If You’ve Been Served With One
Read the motion carefully with your attorney and identify which rule it invokes, because the defenses differ. A Rule 11 motion targets your filings and legal positions. A Rule 37 motion targets your discovery conduct. A § 1927 motion targets your attorney personally.
Your written response should address each allegation directly. Common defenses include showing that a reasonable investigation supported the challenged filing, that a discovery failure was unintentional and has since been corrected, or that the opposing party’s own conduct contributed to the problem. When the motion alleges a discovery failure, sometimes the most effective response is simply producing the requested information. Fixing the problem before the hearing can significantly reduce the chance of sanctions or narrow the penalty to the costs your delay caused.
Don’t miss the deadline for responding. A judge who sees no opposition to a sanctions motion is far more likely to grant it. And don’t treat the motion as a personal insult that warrants escalation. A retaliatory sanctions motion that lacks genuine merit can backfire, putting you in the position you’re trying to escape.
Appealing a Sanctions Order
Sanctions orders are reviewed under the abuse-of-discretion standard, which gives the trial judge significant room. An appellate court won’t reverse simply because it would have decided differently; it looks for clear errors in reasoning, penalties wildly out of proportion to the conduct, or procedural failures like denying the sanctioned party a chance to respond.
Timing creates a practical problem. Most sanctions orders issued during ongoing litigation are not immediately appealable. Under the final-judgment rule, you typically must wait until the entire case is resolved before challenging the sanctions on appeal. A narrow exception, the collateral order doctrine, allows immediate appeal of orders that conclusively resolve an issue completely separate from the case’s merits and that would be effectively unreviewable after final judgment. Sanctions orders sometimes qualify, but the standards are strict and many do not.
What a Sanctions Order Means for an Attorney
For lawyers, a sanctions order can cause damage well beyond the immediate penalty. Malpractice insurance policies typically do not cover sanctions; most policies explicitly exclude fines, penalties, and forfeitures from their definition of covered damages. An attorney ordered to pay $50,000 in sanctions generally pays that out of pocket.
A pattern of sanctions can also lead to state bar disciplinary proceedings. Courts have the authority to refer attorneys to disciplinary bodies, and a documented history of sanctioned conduct undermines professional standing. A sanctions order creates a permanent record that opposing counsel in future cases can discover and use to build credibility arguments with the court. One order for a reasonable mistake is survivable. Multiple orders suggest a pattern, and patterns attract disbarment proceedings.
