A more thorough explanation:

Interference with contract is a legal term that refers to the act of intentionally causing one party to breach a contract with another party. This is also known as tortious interference with contractual relations.

For example, if Company A has a contract with Company B to provide services, and Company C convinces Company B to break the contract and work with them instead, Company C may be liable for interference with contract.

Another example could be if an employee has a contract with their employer and a third party convinces the employee to breach the contract and work for them instead.

These examples illustrate how interference with contract can cause harm to the party that was relying on the contract. It can result in financial losses, damage to reputation, and other negative consequences.
