The parties concerned will not be arrested and their families will not be implicated if they are prosecuted for overdue installment payment. However, if the parties fail to pay as agreed, it is a breach of contract and they need to bear the corresponding liability for breach of contract according to law. For the specific situation, please ask relevant parties to verify and determine according to the actual situation and relevant laws and regulations. Relevant laws and regulations: Article 107 of People's Republic of China (PRC) Contract Law: If a party fails to perform its contractual obligations or fails to perform its contractual obligations, it shall bear the liabilities for breach of contract such as continuing to perform, taking remedial measures or compensating for losses. Article 108 If a party expressly expresses or shows by his own behavior that he will not perform his contractual obligations, the other party may require him to bear the liability for breach of contract before the expiration of the performance period.
