Over 2 years ago I lent my son-in-law a substantial amount to buy and completely renovate a house for his family to live in. He said he would re-mortgage the house afterwards as it would have significantly more equity. I was to leave an amount not repayable for which he voluntered to pay interest. No monies have been forthcoming. For family reasons nothing was put in writing but he does not deny the debt. However he extended himself financially in refurbishment even though he is very handy and did as much work as he was able. He has had some problems so I decided to leave things for a while.
I no longer work as I am retired and have been in expectation of repayment.
