Motion for Sanctions

Asks the court to punish litigation misconduct — frivolous filings, discovery abuse, or evidence destruction.

Governing rule
Fed. R. Civ. P. 11; 37(b); 37(e)
Read the rule

What it is

A request asking the court to penalize the opposing party (or their lawyer) for misconduct — frivolous filings under Rule 11, discovery abuse under Rule 37, or destruction of evidence under Rule 37(e). Penalties range from monetary fines to evidence preclusion to default judgment.

When it's used

Most often filed after a party violates a discovery order, destroys responsive documents, or makes representations to the court without evidentiary support. Rule 11 motions require a 21-day safe-harbor letter before filing.

What the other side does

Opposes by disputing the misconduct, arguing the position was substantially justified, or asserting the sanction sought is disproportionate.

Common outcomes

Granted (fees, fines, evidentiary sanctions, adverse-inference instruction, or in extreme cases default), denied (no misconduct or harmless), or granted with a lesser sanction. Severe sanctions like dismissal require willful conduct.

Not legal advice. Motion practice varies by court, judge, and case type. Local rules and standing orders frequently modify the federal defaults shown here. If you're facing a motion or considering filing one, talk to a lawyer about strategy and timing for your specific case.
