I recently bought an AQHA mare from a girl who bought this mare from an auction and said she had her transfer papers and registration certificate at her old house and would get it to me the next day, she bought the mare in Nov 2019 and I bought the mare Jan 2020. She never transferred her to her name. I got the registration Certificate the next but not the transfer paper claiming she forgot to grab it. She said she would mail it to me so I agreed. Fast forward 4 weeks still no transfer paper and I researched online the auction she bought from and was able to see my mare being auctioned WITHOUT a transfer! I confronted the girl about it and she said she had mailed me the transfer already so I thought maybe she had gotten in contact with the registered owner and gotten a transfer signed. Well 2 more weeks passed and still no transfer. I was able to find contact info of the registered owner and talk to her but now she wont sign a transfer form unless I pay her $500. She also mentioned that the girl I bought her from knew this and had agreed to the transfer fee and never heard from her again. The registered owner said I could sue the girl I bought the mare from for lying about the transfer paperwork. At this point I don't have the money to pay 500 to get her transferred to me. What can I do?
