A person involved in a lawsuit, either as a plaintiff or defendant. In Japanese, the term varies by context and formality, with common legal terms like 訴訟当事者 and more specific roles like 原告 or 被告.
Referring to any person or entity involved in litigation, without specifying plaintiff or defendant.
Standard legal term for a litigant or party to a lawsuit. Neutral and widely understood.

Specifically the party against whom a lawsuit is brought.
Standard term for defendant in legal contexts.
The defendant pleaded not guilty.
Use 訴訟当事者 when you don't need to specify whether the person is suing or being sued. In most practical situations, however, you will use 原告 (plaintiff) or 被告 (defendant) because the role is clear from context.
In Japanese legal contexts, litigants are often referred to by name plus a title like 氏 (し) or by their role (原告, 被告) rather than a generic 'litigant'. For example, '原告田中氏' (the plaintiff Mr. Tanaka).
