Swimming legend David Wilkie left a £2m fortune after his death at the age of 70.
Wilkie won three Olympic medals during his career as well as three world titles.
His family released a statement announcing his passing in May following his courageous battle with ill health.
They said: ‘It is with great sadness that the family of David Wilkie MBE announce that he died peacefully surrounded by his family this morning following his brave battle with cancer.’
Probate records have revealed Wilkie had not written a will but it is expected his £1,948,525 estate will be inherited by his wife Helen and their children Natasha and Adam.
The Scot won 200m breaststroke gold in Montreal in 1976 as well as two Olympic silver medals and three world titles.

He collected Olympic silver in Munich in 1972 and won World Championship gold the following year.
Wilkie added three more Commonwealth medals for Scotland, including two golds, in 1974.
In 1975, he completed a 100m and 200m breaststroke double at world level and was voted British Sportsman of the Year by sports writers.
Wilkie’s crowning moment came one year later in 1976 with an extraordinary performance in Montreal with his Olympic triumph taking more than three seconds off the world record time.
He also came second in the 100m event in Canada.
Unbeaten over 200m for four years and the first British man to win Olympic gold in the pool in 68 years he retired one month after the Games at the age of 22.

After hanging up his goggles he became a successful businessman opening Pets’ Kitchen which provides nutritional food for pets.
Wilkie’s son Adam, said: ‘My dad was a truly wonderful man, father, and husband.
‘He achieved so much in his life and those that knew him will never forget his love for life, kindness, and wonderful sense of humour.’
In 2020, Wilkie spoke in depth to BBC Scotland’s This Sporting Life podcast and told how the horror of a terrorist attack at the Munch Olympics impacted him.
He said: ‘On a terrace near where we were sitting we could see these Palestinian guys with masks and guns and the German police. It was right there in front of us.
‘A breaking news story in front of our eyes. Horrific. I was 18. I didn’t see any shooting but you grow up pretty quickly after seeing something like that.’
