In the event of unlawful interference in commercial relations, you must generally prove that you have not suffered economic harm for commercial interference by another company. Among the economic damage, there is a loss of profits. If you participated in a contract negotiation and the contract was signed imminently, you can sue another company for unlawful interference if it convinced the other contractor to separate all business relationships with you. This can happen if a third party offers a potential customer a better price or faster service. If there is a valid contract and the offence with knowledge of the defendant`s law can be documented, it is a simple means of proving unauthorized interference in a civil court. However, courts in most jurisdictions also require the applicant to be able to prove an intervention that could in some way harm the business, which in most cases is financial. In California, it is the elements of negligent interference with the potential economic advantage that the complainant must see: an advertising campaign is probably not unauthorized interference. In Florida, in order to demonstrate unlawful interference in a business relationship, the defendant must have interfered with a known client or client or, at the very least, in strong business prospects. The speculative possibility of developing a future business relationship with someone throughout the Community is generally not sufficient.
In order to assert an unauthorized right of intervention, the applicant must have had a valid contractual or commercial relationship with another party.

Indeed, the contract never existed, so the defendant could not have obtained his violation. The fundamentals of an unauthorized intrusion are: Adam could, for example, refuse to do business with Bill after learning that Bill had a contract or business relationship with an organization that finds Adam in bad moral taste. Adam knows that his bill business is worth more than that of the other organization, and that his refusal to do business will essentially lead Bill to end his contractual or commercial relationship with the other organization. As his motivation was not inappropriate, Bill`s actions would not meet the requirements of the other organization`s illegal interference. Illicit interference in an expected inheritance – Anyone who, by fraud, coercion or other unlawful means, deliberately prevents another person from receiving from a third party an estate or gift that he would otherwise have received, is responsible for the loss of the inheritance or gift of the other.  Whether or not a defendant was aware of the contract or the expectation of business raises a factual question for the court.
If the defendant was not aware, they could not have deliberately interfered with the contract or expectations. Similarly, not all intentional interference is stolen. Since many valid commercial acts could prejudice a contract or commercial expectation, only acts with inappropriate motives will lead to unlawful interference. The application of the above has been amended in British law. In OBG vs. Allan  1 AC 1. Incorrect interference: The uniform theory that dealt with losses by unlawful means such as the extension of the unlawful act of induction of an offence has been abandoned; Committing a breach of contract and causing losses by illegal means was two separate offences. the duty of offence was an unauthorized liability and the intention to create an offence was a necessary and sufficient obligation; a person must have known that he or she would be in breach of contract and intended to do so; That a conscious decision not to examine the existence of a fact could be considered knowledge for the purposes of the unlawful act; that a person who knowingly induced a conventional rupture as a means of purpose had the necessary intention, even if he was not motivated by wickedness, but had acted on the grounds of an economic advantage s
