A co-signer is someone who agrees to take responsibility for your loan if you can't pay. Lenders often ask for one if you have limited credit history, lower income, or a lower credit score-it reassures them that the debt will be covered.

## How It Works

Your co-signer signs loan documents alongside you and is legally liable. Their creditworthiness strengthens your application, sometimes unlocking better interest rates or approval when you might not qualify alone. Both of your credit reports and histories are reviewed.

## The Trade-Off

A co-signer's credit score can be affected while the loan is active (the debt counts toward their debt-to-income ratio). If you miss payments, it damages both credit records. Choose someone you trust completely-a parent, spouse, or close family member usually works best.
