5 warnings for a credit card co-signer
Bad marks can show up on your credit report
Late payments, missed payments or collections on the account? In the eyes of creditors, this is your account, so you're equally at risk for any sort of negative credit reporting and/or collection activities.
Even if you never have to pay a dime, co-signing with someone who doesn't know how to manage credit or just doesn't do it well can cost you money by eroding your own credit. These days everyone from potential employers to loan officers to insurance companies can look at credit reports.
