To co-sign a personal loan, the co-signer and the borrower must first meet the lender's eligibility requirements. Co-signers must usually be at least 18 years old and have good credit.
In addition, they must be willing to provide a guarantee for the loan, which means that they are legally responsible for repaying the debt if the borrower fails to do so. The co-signer and 0borrower will also need to complete a loan application and sign the loan agreement.
Once these steps have been completed, the co-signer's name will be added to the borrower's account, and they will become jointly liable for repaying the debt.
