Thank you for your question
My name is Clare
I shall do my best to help you but I need some further information first
How was this dealt with within the financial part of your divorce?
When was the divorce and have you remarried?
Who kept the house?
You can certainly argue that there is clear evidence that he accepted the £34,000 in full and final settlement - and I believe that the Small Claim Court would agree.
However there is another argument as well
This was undoubtedly a joint debt with your ex and she is as liable for it as you.
Indeed it could be argued that since it was in many ways a family "loan" - sometimes referred t as a "soft debt" and you were entitled to assume that this was a matter between your ex and her family - and accordingly you will join her in in any claim - either within the Small Claim s procedure - or , since you have not remarried, by opening a financial claim within the divorce in an attempt to recover the overpayment to her father ......
Please ask if you need further details
No that is not relevant to your claims
You are welcome - good luck
