this sounds like a badly drawn up will which needs to be looked at properly - I would definitely get him to get some proper legal advice - skip the CAB and go straight to a proper lawyer.
If I'm right (which I may not be), it wasn't badly drawn up at all - it may be that the invalidity is some spurious legal BS that someone has misunderstood.

But +lots to going to a proper lawyer.
