Interference with Contract

Tortious interference

The rule

Intentional interference requires a valid contract or expectancy, defendant's knowledge, intentional acts inducing breach or disruption, and damages; fair competition privileges interference with mere prospective advantage.

In plain English

Intentional interference with a contract occurs when someone knowingly disrupts an existing contract or a potential contract between two parties. To prove this, the plaintiff must show that there was a valid contract, the defendant knew about it, intentionally acted to interfere, and that the plaintiff suffered damages as a result.

Worked example

Company A has a contract with Employee B. Company C, knowing about this contract, offers Employee B a better job and convinces them to leave Company A. As a result, Company A loses business and suffers financial harm. Company A can sue Company C for intentional interference with its contract.

Memory hook

Don't break the deal—interference can lead to a legal meal!

The trap

Exams often include scenarios where the interference is subtle or where the defendant claims they were just competing fairly, which can confuse students about what constitutes wrongful interference.

How examiners test it

Questions typically present a fact pattern involving two parties with a contract and a third party who disrupts it, requiring students to identify the elements of intentional interference.
