You should treat the assets returned in box 76 on their merits. You should be able to accept most without enquiry. And if the value returned is relatively small and there is no clear evidence of significant undervaluation you will not normally need to ask for any additional information. The contents page (IHTM10000) tells you where you can get guidance to help you deal with some of the more unusual assets that may be included in box 76.
