One of my family members wanted a puppy from me and the price for the puppy was $100 and she paid me $40 and agreed to pay me the remaining $60 when she got her child support. So we made a handwritten agreement stating that she would pay me the $60 on 3-20-12, but it wasnt notarized? And i have messages before the 20th just asking to make sure she was still going to pay and she said yes in the emails. Now she gave the dog to her brother who will not pay me anything for the dog and she is now telling me that we never signed a paper and that i forged her signature which isnt true at all. I still have the paper she signed and i wanted to take her to court but wasnt sure if the agreement i had would work?
