My ex and I had signed an agreement in principle in our family case. In this deal I had agreed to take her loan of 33500.00. I immediately contacted my bank to pay the loan off the same day we signed. 5 days later I was informed she was not accepting the deal we had agreed to and I am now stuck with the loan. I managed to stop payment on the balance of the loan but when I received the letter from the bank stating she had defaulted on it, I later ended up paying the balance anyway.

Can I sue for my money or not?
