Intentional interference with contractual relations is a common law tort that applies to an activity or activities that causes a damage to contractual relations between parties. It may include acts that prevent parties from contracting or it may cause the parties who have already entered into a contract to fail to perform or otherwise complete their contractual relations.
An example may be statements by an individual set to prevent someone from entering into a contract. Of course not all such statements may be interference with a contract as in an open market individuals can compete for contracts and can attempt to properly influence individuals so that they may decide to chose between one contractor or another.
