The tort of slander of title and the related tort of disparagement of property are based on an intentional interference with economic relations. They are not personal torts; unlike slander of the person, they do not protect a person's reputation.” Bass v. Planned Mgmt.
76-9-404. Criminal defamation. (1) A person is guilty of criminal defamation if he knowingly communicates to any person orally or in writing any information which he knows to be false and knows will tend to expose any other living person to public hatred, contempt, or ridicule.
Definition: defamation from 28 USC § 4101(1) | LII / Legal Information Institute.
Generally, to prove defamation, you must show that a false statement was made, about you, to third parties, and which caused you damage. Once you have evaluated your case, and determined that you can satisfy these elements, you can then proceed with pursuing your matter.
In Utah, person claiming defamation must prove that: The information was false and unprivileged. In publishing the statements, the defendant acted with the “requisite degree of fault.” When applied to a private individual, this requires simple negligence, while a public figure must prove actual malice.
