The word "Sealed" is what I see when a will has been proven in Scotland - because the deceased died there - but there is a necessity, as I understand it, to access assets in England & Wales. Bear in mind that England & Wales on the one hand, and Scotland, on the other, are different legal domains so getting "probate" in Scotland doesn't give you authority to access to any funds or whatever held in England & Wales. The will needs to be "read across" and authorised south of the Border. Presumably it's a simple process....
(I'm using English terms here for events in relation to probate and wills
"Confirmation Sealed" is not a phrase I've seen before so I'm unclear exactly what it means - I know that Scots "probate" procedures have a "confirmation of the executors" so whether that's something to do with it, I've no idea.
All this might suggest
that there is a will - though if Letters of Administration were needed to access stuff in England & Wales, because there's no will, I have to say that I've no idea what the phrase might be - it could be "Confirmation Sealed" implying there is no will
If there is a will, the only certain place to access it will be via Scotland (see ScotlandsPeople because I think that they advise you what to do if the will isn't on-line). Anything in England & Wales might just be a simple confirmation that X and Y can distribute the estate.
Slightly too many questions in this answer but at least it might help to point you in the right direction.
