A more thorough explanation:

Definition: Litigious is an adjective used to describe a person or company that is quick to sue others, even if the lawsuits are unnecessary, unfounded, or retaliatory. It can also refer to something related to legal action or lawsuits.

Examples:

• John is a litigious person who sues anyone who disagrees with him.
• The company has a reputation for being litigious and has been involved in numerous lawsuits.
• The contract included a litigious clause that required any disputes to be settled in court.

In these examples, the term "litigious" is used to describe individuals or entities that are prone to engaging in legal action, even if it is unnecessary or unfounded. The third example illustrates how the term can also refer to something related to legal action, such as a clause in a contract that requires disputes to be settled in court.
