The Moment
A parent, sibling, child, or other family member is asking you to cosign a loan — for a car, apartment, student loan, or personal loan. They say they will make all the payments. They just need your name on the paperwork.
This feels like a small ask. It is not. Cosigning is one of the highest-risk financial decisions you can make, and it destroys more family relationships than almost any other money decision.
The Reality of Cosigning
You are the backup payer — and backups get called. According to a Federal Trade Commission study, as many as 75% of cosigned loans end up being partially or fully repaid by the cosigner. The borrower needed a cosigner because a lender — whose entire business is assessing credit risk — decided they were too risky. You are overruling a professional risk assessment with your emotions.
Your credit is at stake. The loan appears on your credit report. If the borrower pays late, your credit score drops. If they default, you owe the full balance. If you cannot pay, your credit is damaged and the lender can sue you, garnish wages, or place liens on your assets.
The relationship risk. If the borrower misses payments and you are forced to pay, resentment builds. If you refuse to cosign, there may be short-term friction — but it is far less destructive than years of financial entanglement and broken promises.
You cannot easily exit. Most cosigned loans cannot be removed without refinancing — which the borrower could not qualify for in the first place. You are locked in until the loan is fully repaid.
Better Alternatives
Gift what you can afford to lose. If you want to help, give money directly — an amount that would not hurt you if it disappeared. A $2,000 gift toward a car down payment is better than cosigning a $25,000 loan.
Help them build credit. Add them as an authorized user on your credit card (your payment history helps their score) without giving them the physical card. This builds their credit so they can qualify on their own.
Help them find alternatives. Credit unions offer lower rates and more flexible lending. Secured credit cards build credit. Some lenders work with thin credit files. Help them find a path that does not put your finances at risk.

Frequently Asked Questions
What if it is for my child's student loan?
This is the most common and most understandable cosigning scenario. If you choose to cosign, set clear expectations: the student makes payments, you monitor the account monthly, and you have a written plan for what happens if they cannot pay. Consider Parent PLUS loans instead — they are in your name from the start, with no pretense of shared responsibility.
Can I cosign but protect myself legally?
Not effectively. A written agreement between you and the borrower is not enforceable against the lender — you owe the full amount regardless. You can sue the borrower for repayment, but suing a family member is the outcome you are trying to avoid.
