<prompt> Human: So this might up being more trouble than its worth, but as the title says my wife made a poor decision when she was 18 and co-signed a small student loan for her boyfriend at the time. The amount of the loan was about 5,000. Fast forward some time, they are no longer together and she starts getting threatening calls from collectors on this loan. After trying to get her ex to deal with it for a few months, he stops responding to her. Shes tried reaching out to his family too, but they werent helpful either. So shes been stuck making minimum payments on his loan for the past 5 or 6 years. We got married, and this debt is now my debt too and Id like to see if theres anything we can do about it. Would it be worth it to try and sue him? Would we even have a case since she co-signed?I posted this to rlegaladvice as well and havent gotten many responses, so trying here as well. Thanks in advance for any input! EDIT: The loan was for college courses that the guy didnt even finish.  <response>: She could sue him and she could win,BUT that doesnt mean he will pay her.
