About three years ago, I borrowed money from my ex, just after we split up. It was borrowed in a few separate amounts, and part of it is for her car being transferred to me when she upgraded. The total amount is around thirteen thousand dollars. We wrote the amounts down on a piece of paper with a general agreemenintot that I would repay it when possible. She kept the paper and I didn't keep a copy. I've been repaying it in varying amounts but for the most part fifty dollars a fortnight. I've paid off four thousand dollars.
However, for the last few months I've been asking her for a copy of the document so that I can clarify exactly how much I still owe.
She keeps fobbing me off. I'm getting irritated because I can't remember all the details, and even though I'm sure I have quite a few thousand dollars left to go, I'd like to know for sure, and to clarify that we're on the same page. The records that I've kept show that I've paid from three different bank accounts in to two of her accounts , and some of the debt has been reduced in lieu of cash when I did occasional work for her - so lots of potential for misunderstandings. Our relationship has deteriorated a lot to only minimal communication about child custody issues.
I feel like I want to stop repayments until I have a copy of the original agreement. Is this a reasonable thing to want? What else can I do to get some control over this situation?
