Oh trust me, i'm a firm believer in insurance; that's one thing that will be full belt and braces.
If there is a registration process in place i will be part of it, that's for sure. No point cutting corners that can come back and bite you firmly in the ass at a later stage (with a fine). I'd much rather be official and not have to skulk around in the bushes like a cowboy (do cowboys skulk in bushes?).
