A TOY-making tycoon’s sons are locked in a High Court battle over his multimillion-pound estate — after DNA tests allegedly showed he did not father one of them.
Stuart Marcus, who died in 2019, founded Kitfix Hobbies in 1962 and built up a business worth £14.5million.
His sons, Edward, 46, and Jonathan, 42, worked with him as the brand, based in Swaffham, Norfolk, grew and diversified.
But Jonathan says his older brother is the product of a 1977 one-night stand their mother Patricia had and has no right to a share of the family trust.
Edward denies DNA proves he was not Stuart’s natural child.
He also argues that, since his mum’s affair may have lasted years, it is equally possible Jonathan is the illegitimate son.
His barrister, Matthew Mills, told the court: “Fundamentally, this case is about the most important question in a person’s life – their identity.
“What this case seeks to do is to entirely turn my client’s life on its head.”
The judge has reserved his judgment, to be given at a later date.
