I lived with a roommate in an apartment for 1 year about 1 year ago. It was 'co-singed'.
My lease ended in August. Around May, landlord came to me saying that he did not receive April rent. Apparently, my roommate wrote a check, there was a problem, and it didnt get processed. So I told my roommate to check if the check was processed from his bank account and if April rent really didnt get processed, I told him to pay the rent. He said he will do it, but apparently he did not pay it. Ever since May, every month, the landlord contacted me saying that he still didnt receive April rent. I kept telling my roommate to check it, and in August, my roommate told me he took care of it. I also did not get contacted by the landlord, so I thought he actually paid the rent.
However, I found out today that I have bad credit score because he still did not pay the April rent. I paid the rent the every other month and my roommate was suppose to pay the rent the every other month. He wrote the check that didnt get processed and screwed me up. Is there anyway to fix/dispute my credit score?
