Hi Kelly
I assume that if it is a joint claim and one member has an appointee - the managed migration will be deferred for both of them. (I don't know this for certain)
If someone is an official DWP appointee - it should cover all their benefits - but I know a couple of members here have had issues with one department getting the information from another. So you may have to point it out to them, but the process shouldn't be repeated.
