Legal analysis: Grandpa’s overdue credit card will have no impact on his grandson. First of all, a bad credit report affects the economic life of the parties, such as applying for credit cards and loans. Generally speaking, bad records of parents will not affect their children, because in the credit reporting center, they are all independent credit entities and have no relationship with each other. At the same time, the credit reporting system itself does not have a blacklist, it only objectively records credit status. The blacklist is compiled by banks and other financial institutions themselves. Credit reporting is a professional, independent third-party agency that establishes credit files for individuals or enterprises, collects and objectively records their credit information in accordance with the law. It is an activity that provides credit information services to the outside world in accordance with the law. It provides a platform for professional credit institutions to share credit information.

Legal basis: Article 15 of the "Regulations on the Administration of the Credit Reporting Industry" If the information provider provides personal adverse information to the credit reporting agency, the information subject shall be notified in advance. However, adverse information disclosed in accordance with laws and administrative regulations is excluded.
