Well you put all the evidence together ie bank statements, letters etc in one bundle and make a photo copy of the whole bundle and keep it separate and then make another copy of everything for yourself and at the appointment hand in the originals bundle and the copies bundle but keep one of the copies bundle for yourself. Dont use plastic wallets or anything and stick the photos onto a piece of paper with prit stick. Does that make sense?
Do you know there is a new rule now about having to make £18,600?
