It's called tortious interference with contract and the standards vary state by state. However, the common elements are (1) the existence of a contract subject to interference; (2) the occurrence of an act of interference that was willful and intentional; (3) the act was a proximate cause of the claimant's damage; and (4) actual damage or loss occurred. Some states also recognize causes of action for interference with prospective relationships, although these are notoriously hard to prove.
