Tort law: Dignitary torts - Alienation of affections - Malicious prosecution - Abuse of process - Breach of confidence

Alienation of affections is a common law tort, abolished in many jurisdictions. Where it still exists, an action is brought by a spouse against a third party alleged to be responsible for damaging the marriage, most often resulting in divorce. The defendant in an alienation of affections suit is typically an adulterous spouse's lover, although family members, counselors, and therapists or clergy members who have advised a spouse to seek divorce have also been sued for alienation of affections.

The tort of alienation of affections often overlaps with another "heart balm" tort: criminal conversation. Alienation of affections has most in common with the tort of tortious interference, where a third party can be held liable for interfering with the contractual relationship between two parties.

Malicious prosecution is a common law intentional tort. While like the tort of abuse of process, its elements include (1) intentionally (and maliciously) instituting and pursuing (or causing to be instituted or pursued) a legal action (civil or criminal) that is (2) brought without probable cause and (3) dismissed in favor of the victim of the malicious prosecution. In some jurisdictions, the term "malicious prosecution" denotes the wrongful initiation of criminal proceedings, while the term "malicious use of process" denotes the wrongful initiation of civil proceedings.

Abuse of process is the unjustified or unreasonable use of legal proceedings or process to further a cause of action by an applicant or plaintiff in an action. It is a claim made by the respondent or defendant that the other party is misusing or perverting regularly issued court process (civil or criminal) not justified by the underlying legal action. In common law it is classified as an intentional tort. It is to be distinguished from malicious prosecution, another type of tort that involves misuse of the public right of access to the courts.

The tort of breach of confidence is, in United States law, a common law tort that protects private information that is conveyed in confidence. A claim for breach of confidence typically requires the information to be of a confidential nature, which was communicated in confidence and was disclosed to the detriment of the claimant.

Establishing a breach of confidentiality depends on proving the existence and breach of a duty of confidentiality. Courts in the US look at the nature of the relationship between the parties. Most commonly, breach of confidentiality applies to the patient-physician relationship but it can also apply to relationships involving banks, hospitals, and insurance companies and many others.

There is no tort of breach of confidence in other common law jurisdictions such as the United Kingdom or Australia, however, there is an equitable doctrine of breach of confidence.
