A more thorough explanation:

invadiatus

Invadiatus is a term from Law Latin that refers to a person who is under a pledge.

• A person who has taken a loan from a bank and has pledged their property as collateral is an invadiatus.
• When a person is released on bail, they become an invadiatus until they appear in court.

These examples illustrate how invadiatus is used to describe a person who has given a pledge or security for a debt or obligation. It is a legal term that is used to describe a specific situation where a person's rights or property are held as security until they fulfill their obligation.
