I cosigned for a car for my stepson. I thought that if he didn’t pay I would be responsible for the loan, and I was fine with that. What I didn’t realize is that if he was late with his payment, my credit would be affected. I had a credit score of 803 when I signed. He missed payments, and now my credit score is lower. Even though this is not my loan, will my credit report be affected for seven years? Is there a way to correct this?
