Issues-Interference with Contractual Relationship or Business Expectancy-Burden of Proof is a legal concept used to determine who has the responsibility of proving that one party has interfered with the contractual relationship between two parties. This concept is applicable when there is a dispute between two parties as to whether or not one party has interfered with the other party's contractual relationship or business expectancy. The burden of proof is usually on the party alleging interference and the applicable standard of proof varies depending on the jurisdiction. The two main types of Issues-Interference with Contractual Relationship or Business Expectancy-Burden of Proof are Direct and Indirect Interference. Direct interference occurs when one party deliberately interferes with the contractual relationship or business expectancy of the other party. Indirect interference occurs when the actions of one party are deemed to have caused the contractual relationship or business expectancy of the other party to be disrupted. In both direct and indirect interference cases, it is up to the party making the claim of interference to prove that the interference is the cause of the disruption. This involves establishing that the interference was intentional and that it was the proximate cause of the disruption. Depending on the jurisdiction, the party making the claim must prove the interference with either clear and convincing evidence or a preponderance of the evidence.
