I'm from the UK and I've just about completed making an indie game and had some interest from several online retailers that sell games. This requires me filling in a basic contract.
I'm just one guy who works from home as a hobby, I go by a studio name for my game solely because that's the norm.
Do I need to register my 'company' name before I can go any further?
EDIT: I'm already registered as self employed from prior work in a different field
