While royal wills are not made public, it's believed Philip's four children - Princess Anne and Princes Charles, Andrew and Edward - were told they can "take what they want" from their father's collection of 13,000 books, which have been returned from Wood Farm to the library at Buckingham Palace.
Small personal items are likely to have been passed to family members, with it previously being reported that his granddaughter, Lady Louise Windsor, would inherit his horse carriages as she shared her grandfather's passion for carriage driving.
Charles is believed to have been given his father's collection of Robert Falcon Scott's treasured mementos of his ill-fated 1912 South Pole expedition.
According to the insider, Philip spent some time after being released from hospital in March signing photos of himself, which were placed in frames with his cypher on them with the intention of being given as gifts to those who had looked after him.
A royal spokesperson refused to confirm the reports of how Philip's assets will be divided.
They simply said: "This is a personal matter for the family and as such arrangements are private."
