A personal loan guarantor loan is borrowing where another person agrees to repay the debt if the borrower fails to do so. The guarantor could be asked to cover missed payments, interest and other charges, and their credit record may be affected if the account falls into arrears. Both people should check the agreement carefully and consider whether the repayments are affordable, as the lender may take legal action if the debt remains unpaid.
