A surety is a person who assumes responsibility to pay a loan if the borrower is unable or unwilling to repay it. In addition, relevant information about the suretyship is also recorded in the credit bureau, and when the surety applies for a loan themselves, the obligation you have undertaken will be taken into account when analyzing their financial data. As a result, before you ask another person to act as a surety, you should consider that you are not only imposing responsibility on them, but also, to some extent, reducing the amount of credit resources available to them.
