I. Elements of the Crime of Contract Fraud The crime of contract fraud refers to the act of defrauding the other party's property by fabricating facts, concealing the truth, setting traps and other means in the process of signing and performing a contract for the purpose of illegal possession. Or one party to the contract deliberately conceals the real situation, or deliberately tells the other party false information to induce the other party to make a wrong expression of intention, so as to sign or perform the contract with it. Generally speaking, a contract constitutes fraud and must meet the following four conditions: (1) The fraudster has the intention of fraud. The intention of fraud refers to knowing that one's statement is false, which will lead the other party to fall into a wrong understanding, hope or connive at this result. The intention of fraud includes two aspects: one is the intention to state false facts; The second is the intention to mislead others. (2) The fraudster has committed fraud. Fraudulent behavior refers to the behavior that fraudsters deliberately state false facts or deliberately conceal the real situation to make others fall into a wrong understanding. Deliberately stating the wrong facts and deliberately concealing the true situation are two aspects that constitute fraud. Deliberately stating the wrong facts, such as describing fake and shoddy goods as high quality and low price. Deliberately concealing the truth means that the actor has the obligation to tell the other party the truth and deliberately does not tell it. Does silence constitute fraud? According to the laws of most countries, when the perpetrator is obliged to tell the truth without explaining or keeping silent, it constitutes fraud. China's laws are similar to the above provisions on whether silence constitutes fraud. For example, Article 28 (Product Quality Law) stipulates that a seller who sells a product that does not have the performance that the product should have should make an explanation to the consumer or user in advance, otherwise he shall bear civil liability. This clause shows that silence when there is an obligation to explain constitutes fraud. In addition, those who have the obligation to explain according to the principle of good faith cannot remain silent. (3) The deceived person falls into a mistake due to fraud. The so-called mistake refers to the defect in understanding the important situation such as the content of the contract. In order to constitute fraud, there must be a causal relationship between the wrong understanding of the deceived person and the fraudulent behavior of the fraudster. In other words, if a fraudster enters into a contract, it must be that the false information provided by the fraudster is closely related to the contents of the contract, and the fraudster has misunderstood the contents of the contract because of the false information provided by the fraudster. (4) The fraudster expresses his intention by mistake. If the fraudster's expression of will is not made because of fraud, it does not constitute fraud. This shows that there is a causal link between the fraudster's expression of will and fraud. Second, the situation of contract fraud What are the situations of contract fraud? There are five types. The following are five types of contract fraud. 1. Sign a contract in the name of a fictitious unit or use the name of others; 2, forged, altered, invalid bills or other false proof of property rights as a guarantee; 3, no actual performance ability, in order to fulfill the small contract or part of the contract, to deceive the other party to continue to sign and perform the contract; 4. Escape after receiving goods, payment, advance payment or secured property from the other party; 5. defrauding the other party's property by other means.
