Ordering wills:Unfortunately it is not currently possible to order a copy of the will from us
If you are referring to this particular probate index All England & Wales, National Probate Calendar (Index of Wills and Administrations), 1858-1995 So long as the text you read does not have the word ADMINISTRATION, then what you order (for £1.50 from https://probatesearch.service.gov.uk/) will be a copy of the WILL the person made. So yes it will say who the beneficiaries are. Which may or may not be interesting. If it does have ADMINISTRATION in the text, it means there was no will. And while it could possibly be useful, it usually isn't, as you already know who applied for the administration from the Calendar)
