A more thorough explanation:

Jactitation of title is also known as slander of title. It refers to a false statement, either spoken or written, that creates doubt about someone else's ownership of a property.

For example, if someone claims to own a piece of land that actually belongs to someone else, it is considered jactitation of title. Another example could be if someone spreads rumors that a certain property has liens or other legal issues, even though there is no evidence to support these claims.

These examples illustrate how jactitation of title can cause harm to someone's reputation and potentially affect their ability to sell or transfer their property.
