What Is “Lawsuit” in Spanish? The Core Translations

Before getting into nuance, here’s a fast-reference table showing all major Spanish translations of “lawsuit”:

No single word perfectly covers every use of “lawsuit” in English. That’s not a quirk — it’s actually how Spanish-speaking legal systems are structured, where different stages and types of legal action have distinct names.

Breaking Down Each Translation

La Demanda — The Most Common Translation

La demanda is the go-to word for “lawsuit” in everyday Spanish. It refers specifically to the formal written claim that a plaintiff submits to the court when initiating legal action. Think of it as the document you file — or, by extension, the legal action that document starts.

Example sentences:

• Ella presentó una demanda contra la empresa por daños y perjuicios. — She filed a lawsuit against the company for damages.
• La demanda fue desestimada por falta de pruebas. — The lawsuit was dismissed for lack of evidence.
• El juez admitió la demanda a trámite. — The judge accepted the lawsuit for processing.

You’ll also hear the phrase entablar una demanda, which means “to bring a lawsuit” or “to file a lawsuit.” This is the verb phrase most equivalent to the English “to file a lawsuit.”

El Pleito — The Legal Dispute

El pleito carries a slightly broader, more informal energy. While it can mean “lawsuit,” it more precisely refers to the legal fight or dispute itself — the ongoing conflict between two parties. It’s also used colloquially to mean any argument or quarrel.

In a legal context, pleito often describes the adversarial nature of the proceeding.

Example sentences:

• El hombre estaba seguro de que su pleito era fuerte. — The man was confident that his lawsuit was strong.
• La empresa entabló un pleito contra la competencia. — The company filed a lawsuit against its competitor.
• Decidir a proceder con un pleito es de hecho una decisión grande. — Deciding to proceed with a lawsuit is indeed a large decision.

El Juicio — The Trial

El juicio most accurately translates to “trial” rather than “lawsuit,” but in casual speech, Spanish speakers frequently use it to mean the entire legal process, including the lawsuit itself. Context matters a lot here.

If someone says “voy a juicio”, they typically mean they’re going to court or facing a trial — not that they’re filing a new claim.

Example sentences:

• Está involucrado en un juicio para impugnar el testamento de su padre. — He is involved in a lawsuit contesting his father’s will.
• El juicio fue suspendido por falta de evidencia. — The trial was suspended for lack of evidence.
• Meter un juicio a alguien — To bring a lawsuit against someone (colloquial, used in some regions)

El Litigio — Formal Litigation

El litigio is the most formal and technical translation. You’ll find it in legal documents, academic texts, and formal written communications more than in conversation. It maps most closely to the English word “litigation.”

Example sentences:

• El número de litigios internacionales en esta materia es muy limitado. — The number of international lawsuits in this area is very limited.
• El litigio entre las dos corporaciones duró cinco años. — The litigation between the two corporations lasted five years.
• Acción de litigio — Litigious action / civil suit

La Querella — Criminal Complaints

La querella is specifically for criminal complaints or formal accusations — situations where someone accuses another person of a crime. It’s not used for civil lawsuits. You’ll hear this word in criminal law contexts across Spain and Latin America.

Example: El acusado enfrenta una querella por fraude fiscal. — The accused faces a criminal complaint for tax fraud.

Differences Between Civil and Criminal Cases in Spanish

One of the most important distinctions in Spanish legal vocabulary is between civil (civil) and criminal (penal) matters — because they use different terminology and different court systems.

Working with Spanish-Speaking Clients or Courts: Tips for Legal Professionals

If you’re an attorney, paralegal, or court interpreter working across language lines, here are some practical notes:

Always use formal register. In Spanish-speaking courtrooms, formal usted is used universally — not the informal tú. Switching to tú by accident signals disrespect or inexperience.

“Demandante” vs. “Actor.” In Spain, the standard term for plaintiff is el demandante. In Mexico and much of Latin America, el actor (from acción — legal action) is more common. Both are correct; context and country matter.

“Juzgado” vs. “Tribunal.” A juzgado is a lower court or single-judge court (common in Mexico and Latin America). A tribunal typically refers to multi-judge courts or higher courts. In Spain, tribunal is the broader term.

Class actions work differently in civil law countries. The U.S.-style class action (demanda colectiva) doesn’t exist in the same form in many Spanish-speaking countries that use civil law systems. Spain and most of Latin America have their own collective action mechanisms, but they vary significantly. Always verify local procedural rules.

Certified interpreters matter. If legal proceedings require Spanish interpretation in U.S. courts, only a court-certified interpreter (intérprete certificado) should be used. Using uncertified interpreters — even fluent ones — can jeopardize the legal record. Byte Aligners Lawsuit

Frequently Asked Questions

What is the most accurate Spanish translation of “lawsuit”?

Quick Answer: La demanda is the most widely understood and commonly used translation, especially in civil legal contexts across all Spanish-speaking countries.

For civil proceedings, la demanda covers the meaning of “lawsuit” most accurately — it refers to the formal legal claim a person submits to a court. If you need a single word that works everywhere, this is it.

When should I use “pleito” instead of “demanda”?

Quick Answer: Use pleito when describing the overall legal dispute or conflict — especially in conversation. Use demanda when referring specifically to the court filing.

Pleito has a broader, more colloquial feel. It can refer to the lawsuit, the legal battle, or even just a heated dispute. Demanda is more precise and formal, pointing specifically to the legal document or claim.

What does “juicio” mean — trial or lawsuit?

Quick Answer: Juicio most accurately means “trial,” but in everyday speech it’s often used to mean “the legal case” or “going to court.”

When someone says they’re “yendo a juicio”, they mean they’re heading into legal proceedings — which could mean a trial, a hearing, or the entire lawsuit. Context clarifies the exact meaning.

How do I say “class action lawsuit” in Spanish?

Quick Answer: La demanda colectiva is the standard translation. Some legal texts also use acción de clase (a more direct calque from English).

Demanda colectiva is widely understood across Latin America and Spain. When writing for a specific legal jurisdiction, confirm the preferred local term with a licensed attorney.

What’s the difference between “litigio” and “pleito”?

Quick Answer: Both mean litigation or lawsuit, but litigio is more formal and technical, while pleito is more conversational.

You’ll see litigio in written contracts, legal documents, and formal correspondence. Pleito turns up more in spoken language and general discussion of legal disputes. In formal writing, litigio is almost always the safer choice.

How do you say “to file a lawsuit” in Spanish?

Quick Answer: The most common phrase is presentar una demanda or entablar una demanda — both mean “to file a lawsuit.”

You might also encounter interponer una demanda (common in Spain), iniciar un juicio (Argentina), or incoar un juicio (formal, archaic). All refer to starting the legal process by submitting a claim to the court.

What is “settlement” in Spanish?

Quick Answer: An out-of-court settlement is un acuerdo extrajudicial. A legal settlement (formal resolution) is un acuerdo de conciliación or simply un acuerdo.

Llegar a un acuerdo means “to reach a settlement.” Poner fin a un litigio means “to end a lawsuit.” If the settlement happens before trial, you’ll often hear acuerdo extrajudicial (out-of-court agreement).

What does “demandante” mean?

Quick Answer: El demandante is the plaintiff — the person who files the lawsuit.

The word comes directly from demandar (to sue or demand). The defendant is el demandado. In criminal law, the accused is el acusado and the prosecutor is el fiscal.

How do you say “I want to sue someone” in Spanish?

Quick Answer: Quiero demandar a alguien — literally, “I want to sue someone.”

You could also say quiero llevar a alguien a juicio (“I want to take someone to court”) or quiero interponer una demanda contra… (“I want to file a lawsuit against…”). The verb demandar is the clearest and most direct choice.

What is a “demanda colectiva” and how is it different from individual lawsuits?

Quick Answer: A demanda colectiva is a class action — a single lawsuit filed on behalf of a large group of affected people, rather than one individual.

Class actions allow many people with similar claims (against the same company or product, for example) to combine their cases. They’re common in U.S. courts and increasingly used in Latin American jurisdictions too, though procedural rules vary by country.

How do you say “lawsuit” in formal legal Spanish writing?

Quick Answer: In formal documents, prefer litigio, acción judicial, or demanda depending on context.

For contracts and legal agreements, phrases like en caso de litigio (“in the event of a dispute/lawsuit”) and resolución extrajudicial de conflictos (“out-of-court dispute resolution”) are standard. Avoid pleito in formal writing — it sounds too casual for legal documents.

What does “acción judicial” mean?

Quick Answer: La acción judicial means “legal action” or “lawsuit” — it refers to the formal process of taking a matter to court.

It’s often used in broader or more procedural statements: “se tomarán acciones judiciales” — “legal action will be taken.” It’s a catch-all phrase when you want to reference the legal process without specifying the stage.

Is “lawsuit” masculine or feminine in Spanish?

Quick Answer: It depends on the word you choose. La demanda is feminine. El pleito, el juicio, and el litigio are masculine.

This matters for adjective agreement and article use. Una demanda larga (a long lawsuit) uses feminine agreement, while un pleito largo uses masculine.

Can I represent myself in a Spanish-speaking court?

Quick Answer: Yes, in many Spanish-speaking jurisdictions you can represent yourself (actuar en nombre propio or ir en pro se), but it’s rarely advisable in complex cases.

Most Spanish-speaking legal systems allow self-representation in some civil matters, but procedural rules, language requirements, and local practice vary significantly. Getting a qualified attorney (abogado) who speaks both English and Spanish is strongly recommended for anything involving formal litigation. TechLawNews 2026
