In a Jam

My dad has asked me if I can lend him some money so that he can take his Taxi driving test to get a taxi licence, the problem with this is that it will be the third time for him to take it and I paid for the first two.

First time was £200, this was to pay for his test and all the other bits that go with it

Second Time £80 as he failed the first one I thought second time would be no probs for him, I was wrong

Third time He is not late for his rent and needs to sit a third test, problem is he is trying to get together £200 and he asked me for £100 of it, if I do that will be £380 or £480 if I lend him the full amount

Now my dad lost his house a little while back and as he had loans out in my name and I was also on the mortgage I was asked to repay alot of money, which I couldn't afford so I had to go bankrupt (I did have a loan so not 100% his fault) but I have lost 10k that I invested with him/in his company/in his house, I wasn't sure what he used the money for but gathered as he was paying me £300 a quarter did it matter, well it turned out it does as I have got nothing back, technically I also lost another 10k as I was supposed to get this when he sold the house, which he didn't sell in time.

So I'm not sure what I should do, do I lend him the money and tell him that's it and I can't afford anymore if he doesn't pass, but if he does pass, at least he will be able to start paying me back, the trouble is I am not that flush since going bankrupt as I no longer have access to credit cards etc as this would tie me over till i get the money back. I do have a small fund tucked away which I wasn't trying to dip in to as I have set it aside for a stag weekend and the end of this month and the Reading festival at the end of August.
