Legal analysis: defaulting on credit cards will not seal up parents' houses unless there is evidence that the actual investor of the property is the party concerned. A credit card is a credit certificate issued by a commercial bank or a credit card company to eligible consumers. The form of credit card is a card with the name of the issuing bank, expiration date, number and cardholder's name printed on the front. Consumers with credit cards can go to specialized commercial service departments for shopping or spending, and then the bank will settle accounts with merchants and cardholders, and cardholders can overdraw within the prescribed limit.
