Defamation is a false accusation of one person to damage the reputation of other person or party. It is the false statement of actual fact. A person or party making a defamatory statement can be a privileged or a normal person.

If he/she is qualified and privileged, he/she should prove that the defamation is intentional or ill-will. In either case, one must prove the defamation in a legal way. The major defenses to a defamation claim are declaring the truth, qualified or absolute privilege, accept that it was a statement of opinion, written consent about the defamation, and defamation is made against someone else or third party.
