Procès vs. poursuite vs. action en justice
While English often uses "lawsuit" or "trial" broadly, French distinguishes between the event, the pursuit, and the formal right. Procès refers to the specific trial or hearing event. Poursuite (often plural) focuses on the active prosecution or the act of chasing someone legally. Action en justice refers to the formal legal claim or the right to file a suit.
Procès
B1This word primarily translates to "trial." It refers to the specific courtroom event or the entire litigation phase where a judgment is made. It focuses on the time spent being judged or the battle between two parties in front of a judge.

(The trial will last three weeks.)

(They won their lawsuit against the insurance company.)

(She wants to settle the matter amicably to avoid a trial.)

(The trial attracted many journalists.)
Poursuite
B2Often used in the plural poursuites, this refers to "proceedings" or "prosecution." It emphasizes the active act of pursuing someone legally, whether by the state (criminal charges) or a private party seeking damages. It implies an aggressive move to hold someone accountable.

(The prosecutor decided to drop the charges.)

(The proceedings were suspended due to lack of evidence.)
Action en justice
C1This translates to "legal action" or "lawsuit" in a formal, administrative sense. It describes the exercise of one's legal right to bring a claim to court. It focuses on the filing of the case rather than the courtroom drama.
Intenter une action en justice coûte cher.
(Bringing a legal action is expensive.)

(Any legal action must be based on solid evidence.)
Summary
Use procès when talking about the trial event or the courtroom battle. Use poursuite (usually plural) when talking about the prosecution or the active act of going after someone legally. Use action en justice for the formal concept of filing a claim or exercising a legal right.
