Demanda vs. juicio vs. pleito
While demanda, juicio, and pleito generally relate to legal conflicts, they represent different stages or aspects of the process. Demanda is the formal document that starts the process, juicio is the actual trial or court proceeding, and pleito refers to the dispute or litigation as a whole, often implying a conflict.
Demanda
B2This refers specifically to the formal complaint, claim, or the act of suing someone. It is the initial document filed by a plaintiff to request justice or compensation. Without a demanda, there is no legal case yet.
El abogado presentó la demanda en el tribunal esta mañana.
(The lawyer filed the lawsuit at the court this morning.)
Si no reparan el daño, les pondremos una demanda.
(If they do not repair the damage, we will file a lawsuit against them.)
La compañía recibió una demanda por discriminación laboral.
(The company received a lawsuit for workplace discrimination.)
Decidieron retirar la demanda para llegar a un acuerdo privado.
(They decided to drop the lawsuit to reach a private agreement.)
Juicio
B2This word translates best as trial or court case. It refers to the legal proceedings where a judge or jury hears the evidence and makes a verdict. It is the event that happens after the demanda has been processed.
El juicio duró tres semanas debido a la cantidad de testigos.
(The trial lasted three weeks due to the number of witnesses.)
Tengo que ir a juicio el lunes para testificar.
(I have to go to court on Monday to testify.)
El juez suspendió el juicio hasta nuevo aviso.
(The judge suspended the trial until further notice.)
Perdieron el juicio por falta de pruebas contundentes.
(They lost the court case due to a lack of convincing evidence.)
Pleito
C1This refers to the litigation, dispute, or legal battle. It focuses on the conflict itself rather than the document or the specific court hearing. It often implies a messy, drawn-out, or contentious struggle between parties.
Prefiero evitar un pleito largo y costoso con mis vecinos.
(I prefer to avoid a long and expensive legal battle with my neighbors.)

(The inheritance caused a family dispute that separated the siblings.)
Es un abogado experto en pleitos comerciales.
(He is a lawyer who is an expert in commercial litigation.)
Ganar el pleito no sirvió de nada porque la empresa bancarrota.
(Winning the lawsuit was useless because the company went bankrupt.)
Summary
To summarize: use demanda when focusing on the initial paperwork or the act of suing; use juicio when talking about the trial, the hearings, or the time spent in court; and use pleito to describe the general legal battle, dispute, or litigation between two parties.
