Can anyone point in me in the direction of an up to date IVA Manual?
Despite several Google searches I can only find a guide. I have a copy from several years ago which I'm sure will have been superceded.

This?

I'm not sure how you'd find if there was a more recent one, given the above is the gov.uk site?
