To establish a claim for intentional interference with contract, [the Plaintiff] must prove by the greater weight of the evidence:
1) A valid contract existed;
2) The contract was breached;
3) [The Defendant] intentionally instigated the breach, or acted with knowledge that the breach would result, and
4) There was no justification for [the Defendant’s] act. An act that interferes with a contract is justified if it is done with a legitimate business purpose and no improper means are used.
An act that interferes with a contract is not justified if its indirect purpose is to injure [the Plaintiff] or benefit [the Defendant] at [the Plaintiff’s] expense.
