What to Do When a Friend Asks You to Co-Sign Their Loan

Co-signing is not a favor — it is a financial commitment. When you co-sign, you are telling the bank that if the borrower cannot pay, you will. Studies show that roughly 40% of co-signers end up making payments on the loan. The bank required a co-signer because they assessed the borrower as too risky; you are essentially overriding a professional risk assessment with your own credit.

How to say no without destroying the relationship: acknowledge their situation honestly, be straightforward about your own financial boundaries, and offer to help in other ways — reviewing their budget, helping them find alternative lenders, or supporting their application process. A real friend will understand that protecting your financial stability is not a rejection of them personally.
