I do county court claims for a living, could fill out the forms for you to send to him, if you decided to actually take it to court it'd cost you a £30 court fee, which is added to the money he owes you if you win and given the circumstances you probably would (think it's slightly less if you do it through money claims on line). Bear in mind a court claim doesn't always mean your going to get paid but not many people would risk their credit rating for £50. Give me a shout via pm if you decide to go the court route, you're good enough to help a fellow baller out with a problem cocker I'm happy to help with debtor problems.
