First of all, I don't know if the "legal person" you mentioned here refers to the legal representative (natural person) of the enterprise, because "legal person" refers to a group, an organization, just a legal person, not the concept of someone we usually refer to; Secondly, it depends on what the guarantee contracts signed by these four companies and guarantee companies are. For example, whether the legal representative has signed a personal joint and several liability guarantee, if such a contract is signed and the debt is not repaid maliciously, the guarantee company will bear legal responsibility if it sues. As for whether to sit in prison or not, it depends on how the court decides. What should be explained here is that the effectiveness of joint and several liability guarantee is very strong, or the guarantee responsibility of joint and several liability guarantee is in no particular order with the debtor's due repayment responsibility. That is to say, if the debtor fails to repay the due debt, the creditor can directly recover from the guarantor who bears the joint and several liability, without waiting until the debt performance period expires. In the current credit practice, under normal circumstances, the guarantee contracts signed are all joint and several liability guarantees.
