I leant my friend £900 to put a deposit down on a flat this time last year, also £200 to live off as at the time he was out of work. He promised me he would pay me back in 2 months and I trusted him. I did everything for him, leant him my car all the ime to see his family, took him out for drinks all the time etc. we have since fallen out as he beat his girlfriend up and I don't want friends like that, she got back with him, turned him totally against me and now is denying having to pay any of it back. What do I do? Is court the best option, and if so how do I go about it?

Do you have any of this in WRITING otherwise it's simply going to be a case of their word against yours.
Evidence is everything.

You are in the UK? I don't know precisely how small claims works there, but I could look for some links. Where in the UK are you, England, Scotland, Wales, Or Northern Ireland?

I'm in england, northampton. I also lent him a fridge freezer and have just found out that he had moved away and taken it with him. Cheers

I have a bank statement which showes the £900 going into his account but the rest was me taking money out and lending it to him.

First please don't use the comments feature for followups. Use the Answer options instead.

Your bank statement only show you gave him the money, it doesn't show that you expected him to pay it back. Without such proof, you are unlikely to get the money back.

Next time get the borrower to sign a note.
