When the statute of limitations to collect a debt is over and that debt has not been collected, it becomes known as zombie debt. This debt can not be brought to court or appear on your credit report after a certain amount of time has passed.
Debt collectors are required to send a debt verification letter when contacting you about your debt. If they do not send you one, then you are able to legally request one.
An issuing creditor is a financial institution, like a bank, that extends loans in the form of credit cards, personal loans, and more. However, like working with any creditor there are both risks and benefits.
A dispute letter is a template that disputes an item on your credit report by reporting that there is incorrect information. The credit bureau will need to provide hard-to-find evidence to counter the dispute.
A cash advance allows you to take money out of the ATM as a short loan offered by your credit card issuer, but there may be more risks than benefits to using this.
