Around 2019, a friend asked me to co-sign a $8,000 loan for a car. I said yes because I trusted him. He stopped paying after 11 months. I got stuck with the remaining $5,200.
I paid it off. I never saw the money again. We're still friends, but it's weird now. That's the thing about joint loans: they don't just share the debt — they share the risk. And if the other person stops paying, you're on the hook for the whole thing.
Let me be clear: a joint loan (or co-signed loan) makes both people 100% responsible. Not 50-50. 100%. The lender doesn't care whose share is whose. They just want the payment.
I had a client — Naomi — who co-signed a $15,000 loan for her brother. He lost his job. He ghosted the lender. Naomi's credit score dropped from 740 to 590. She couldn't refinance her mortgage. She was stuck paying $350 a month for a loan she didn't use.
She came to me two years later. We negotiated a settlement with the lender for $6,000 (60% of the remaining balance). She paid it out of her savings. Her credit started recovering, but it took another two years to get back above 700.
If someone asks you to co-sign, here's what to do instead:
- Offer to help them build their credit first (secured credit card, credit builder loan).
- Give them a gift of cash if you can afford it. A gift has no strings.
- Say no. It's okay to say no. You're not a bank.
If you absolutely must co-sign, get a written agreement with the borrower. It won't protect you from the lender, but it might help in small claims court. And set up alerts so you know if they miss a payment.
Naomi is now back to a 720 credit score. She said she'll never co-sign again. I believe her.
I will keep posting updates on this. Check back soon.
P.S. That friend who stopped paying? He eventually paid me back around $2,000, but not the full $5,200. He sends me a check every Christmas. I don't know whether to cash it or frame it.
