<prompt> Human: Hi. My former roommate and I ran up a 1,100 utility bill. She and I parted ways and the debt went into collections. The bill is registered to both our names but to only my SS which Im sure is terrible. So, currently Ive been paying collections 40 a month and shes not paying anything. Ive pleaded with her to do so, but she never does.Is there anything I can do to make her pay? If not, should I continue paying it? My credit score is currently at 552, so Im not sure if its even worth it.Okay, thanks for any help!edit: Also, she was not on the lease.edit2: Thanks for the advice, folks. I like this subreddit. Small claims court seems to be the general consensus.To answer common questions: I dont have her SSN, unfortunately. But I do have her address, phone number, and a lot of emails between her and I explicitly stating that were both living at the old place. And to copypaste from below, how did this happen? We just fell behind on bills. And they never cut us off. Those were very irresponsible days. I was shocked and confused that it was that high, but I didnt give much of a fuck back then. I give a fuck now, but its a slow climb to zero.  <response>: Small claims court is the easiest and best way to go. Plead the case!
