The war veteran, who died in February aged 100, expressed his final wishes in a six-page document in June 2020.
Official probate papers showed his estate was split equally between his daughters Lucy, 52, and Hannah, 50.
In a final selfless act, he donated his body to medical research or organ transplants, according to the Sun Online.

In April relatives marked the anniversary of Captain Sir Tom’s legendary fundraiser when he walked 100 laps of his garden.
The national inspiration was knighted in May 2020 and passed away at Bedford Hospital, having tested positive for Covid.
He spent the last 13 years of his life living with Hannah and her family in Marston Moretaine, Bedfordshire.
On what would have been his 101st birthday this year, Captain Sir Tom’s family encouraged people to celebrate his spirit of generosity by taking on their own charity challenge.
People were invited to create their own fundraising activity around the number 100, such as baking 100 cakes or reading 100 books.
Events took place from April 30 under the name Captain Tom 100.
He had spoken of the idea before his death in February.
Some of his personal effects could go on show to the public in a museum, his family has revealed.
Medals, smart jackets and a wheeled walker are among some of Sir Captain Tom’s most recognisable possessions.
A bronze statue is being created of the veteran to honour his legacy.
Sculptor Andrian Melka began work on the 2m clay statue in February which will be cast in bronze and donated to Leeds Teaching Hospitals NHS Trust.
It portrays the 100-year-old fundraiser giving the thumbs-up as he completed 100 laps of his garden ahead of his milestone birthday last year.
Sir Captain Tom’s daughter Hannah Ingram-Moore said her father was her “world” in a tribute following his death.
She told of the ‘deafening silence’ in the family’s home and of their sadness at their loss.
“Captain Sir Tom was simply father, Tom and grandad to us,” she said in a message on Twitter.
“He was our world.
“We lived at home as an inter-generational family for over 13 years and although, like many, we weren’t perfect we were perfectly happy.
“He was strong, kind, and full of humour and was the best mentor and confidante you could ever wish for.
“He was a vibrant, caring and modest person who loved nothing more than to cook, mow the lawn, mend things and give sound advice.”
Speaking at the time, Hannah also expressed her hope that her father’s “message of hope will live on”.
