Definitions
What is complaint?
Legal Definition
A complaint is the initial legal pleading that kicks off a civil lawsuit in court. This document formally sets forth the basis for the court's authority to hear the case, outlines the plaintiff's claims against the defendant, and demands specific relief. Under modern rules, this filing must allege enough facts to state a claim plausible on its face.
Plain-English Translation
Think of it as the permission slip you hand in at school; it tells the teacher (the judge) exactly why you deserve credit or detention. It starts everything moving.
Term context
How complaint shows up in legal documents
Why does it matter?
Failure to properly file a complaint can lead to dismissal without prejudice or default judgment entered against the plaintiff. The risk generally falls upon the initiating plaintiff.
When does it matter?
A complaint triggers the litigation process when it is officially filed with the court clerk and subsequently served on the opposing party. This sets the clock for the defendant's response.
Where is it usually seen?
It appears in civil courts, particularly within filings governed by the Federal Rules of Civil Procedure or adopted state versions thereof.
Who is affected?
The plaintiff uses it to assert their rights; the defendant reviews it to understand the allegations and determine if they need to file a formal answer.
How does it work?
First, the plaintiff drafts the complaint detailing facts and legal violations. Then, this document must be formally served upon the defendant party. Finally, the defendant responds, usually with an 'answer,' challenging or admitting the claims made.
