Plain-English court terms
Court Terminology
Court papers often use words that are unfamiliar, technical, or easy to misunderstand. This guide explains common court terminology in plain English, including summons, complaint, answer, motion, service of process, hearing, order, judgment, appeal, plaintiff, defendant, and deadline.
How to use this court terminology guide
Use this page as a starting point when court papers use words you do not recognize. The goal is to help you understand the basic meaning of common terms, not to choose a legal strategy.
Court terminology can change depending on the case type. A word used in a debt lawsuit may not work exactly the same way in eviction, family, probate, criminal, small claims, administrative, or federal court proceedings.
- Find the word in your document.
- Read the full sentence and paragraph where the word appears.
- Check whether the document lists a deadline or hearing date.
- Verify the term through the official court website or self-help center.
- Ask qualified help if the term affects your rights, money, housing, job, benefits, immigration status, or freedom.
People and roles
Common court roles
Court papers often identify people by their role in the case. These labels help show who filed the case, who must respond, and who may make decisions. A role label does not automatically prove who is right or wrong.
Plaintiff
The plaintiff is usually the person, business, organization, or government entity that starts a civil lawsuit by filing a complaint or similar document.
Defendant
The defendant is usually the person, business, organization, or government entity being sued or required to respond in a civil case.
Petitioner
A petitioner is often the person who asks a court for relief in certain case types, such as family, probate, protective order, immigration, agency, or special proceedings.
Respondent
A respondent is often the person who responds to a petition, appeal, agency case, or certain court proceeding. Some courts use respondent instead of defendant.
Judge
A judge is the court official who may decide legal issues, manage hearings, issue orders, and oversee the case.
Clerk of court
The clerk’s office manages court filings, records, case numbers, fees, notices, and procedural information. Court staff usually cannot give legal advice.
Attorney
An attorney is a person licensed to practice law in a particular jurisdiction. Licensing, authority, and good-standing status should be verified through official state resources.
How to verify a lawyerSelf-represented litigant
A self-represented litigant is a person who appears in a case without a lawyer. Courts may also use the phrase “pro se.”
Witness
A witness is a person who may provide information, testimony, records, or observations related to facts in a case.
Court papers
Common court document terms
Court paper terms matter because they often connect to deadlines, response requirements, hearings, service, or court decisions.
Summons
A summons usually gives formal notice that a case exists and may tell the person receiving it when and how to respond or appear.
Read summons basicsComplaint
A complaint usually explains the claims, alleged facts, court authority, and requested relief in a civil case. It often starts the lawsuit.
Read complaint basicsAnswer
An answer may be a defendant’s formal written response to a complaint. It may admit, deny, or respond to allegations and may include defenses depending on court rules.
Motion
A motion is generally a request asking the court to make a decision, issue an order, change a deadline, dismiss a claim, or decide a specific issue.
Notice of hearing
A notice of hearing usually tells parties about a scheduled court event, including the date, time, location, courtroom, judge, or remote appearance details.
Order
An order is a written or stated direction from the court. It may tell parties what they must do, stop doing, file, pay, produce, or prepare for next.
Petition
A petition is a written request asking a court or agency to take action. It is common in family, probate, immigration, protective order, agency, and special proceedings.
Affidavit
An affidavit is a written statement of facts made under oath or affirmation. It may be used to support a motion, request, or other filing.
Declaration
A declaration is a written statement of facts that may be signed under penalty of perjury, depending on the court, agency, and rule involved.
Procedure words
Common court process terms
These words often describe how a case moves through court. They are not instructions for what you should do in your case.
Filing
Filing means submitting a document to the court in the way the court requires. Some courts allow electronic filing, while others require paper filing or special procedures.
Service of process
Service of process generally means formal delivery of legal papers using a method recognized by law so the other side receives notice of a lawsuit or court step.
Proof of service
Proof of service is a document or record showing that papers were served. It may state who served the papers, when, where, how, and to whom.
Hearing
A hearing is a court event where the judge or hearing officer may consider an issue, receive information, hear arguments, review documents, or make a decision.
Continuance
A continuance means a hearing or deadline is postponed to a later date. Courts have rules about when and how continuances may be requested.
Default
Default may happen when a party fails to respond, appear, or take a required step. The meaning and consequences depend on the court and case type.
Discovery
Discovery is the pretrial process where parties gather information from each other or from others. It may include documents, written questions, admissions, subpoenas, and depositions.
Deposition
A deposition is testimony given under oath outside the courtroom, often recorded by a court reporter. It may be used in discovery or later court proceedings.
Subpoena
A subpoena is a written order that may require a person to appear, testify, or produce documents, records, or other evidence.
Court decisions
Orders, judgments, and appeals
These terms often appear when a court has made a decision or when someone is asking another court to review what happened.
Judgment
A judgment is often an official court decision about a claim or case. It may affect money, possession, rights, enforcement, or other relief.
Default judgment
A default judgment may happen when one party does not respond or appear as required and the court enters judgment without that party’s full participation.
Appeal
An appeal is a request for a higher court to review a lower court decision. Appeals usually have strict deadlines and technical rules.
Injunction
An injunction is a court order that may require someone to do something or stop doing something. Rules and standards depend on the case type.
Dismissal
Dismissal means a claim or case is ended, at least for the time being. A dismissal may be with or without prejudice, depending on the order.
Settlement
Settlement means parties resolve some or all of a dispute by agreement instead of having the court decide every issue.
With prejudice
“With prejudice” usually means a claim or case is ended in a way that may prevent the same claim from being brought again.
Without prejudice
“Without prejudice” usually means a claim or case is ended in a way that may allow the claim to be brought again, depending on rules and deadlines.
Enforcement
Enforcement means steps taken to carry out or collect on a court order or judgment. The rules depend on the court, judgment type, and location.
Deadlines and timing
Deadline terms you may see
Court papers may use timing words that affect what happens next. This page does not calculate deadlines. Always verify dates with official court sources or qualified legal help.
- Response deadline: the date or time period for filing a response.
- Hearing date: the scheduled date and time for a court event.
- Service date: the date papers were formally delivered.
- Filing deadline: the last date to submit a document to the court.
- Objection deadline: the deadline to object to a request, order, or recommendation.
- Appeal deadline: the deadline to ask a higher court to review a decision.
Why deadlines are risky
Do not calculate from a glossary
A glossary can explain what deadline words mean, but it cannot tell you the correct deadline in your case.
Deadlines may depend on the court, case type, local rules, service method, weekends, holidays, emergency orders, judge-specific instructions, and the exact words in the document.

This page focuses mostly on civil court terminology. Civil cases usually involve disputes between people, businesses, landlords, tenants, creditors, consumers, employers, employees, agencies, or organizations.
Criminal cases involve government prosecution for alleged crimes. Criminal terminology can be different and may involve constitutional rights, bail, plea, prosecutor, defense attorney, sentence, probation, jail, or prison.
- A civil plaintiff usually brings a civil claim.
- A criminal prosecutor brings charges on behalf of the government.
- A civil judgment is not the same as a criminal conviction.
- A civil complaint is not always the same as a criminal complaint.
- If you are accused of a crime, seek qualified legal help quickly.

How to read court papers when terms are confusing
When a court paper feels overwhelming, start by identifying the document type, the court, the case number, the parties, the deadline, and the action requested.
Do not assume a word has its everyday meaning. A term such as service, answer, motion, order, default, or judgment may have a specific court meaning.
- Find the court name and case number.
- Identify whether you are listed as plaintiff, defendant, petitioner, respondent, or another role.
- Find every deadline and hearing date.
- Identify whether the paper asks for a response, appearance, payment, evidence, or records.
- Save the envelope and proof of service.
- Contact official court help, legal aid, or a licensed attorney if the risk is serious.
