The technology giant had accused the British mogul, who died last year when his yacht sank, of fraud in the sale of his company in 2011.

The estate of Mike Lynch, the British technology executive who died when his yacht sank off the Italian coast last summer, and his former business partner owe Hewlett Packard Enterprise more than 700 million pounds ($945 million) over the 2011 sale of his company to Hewlett-Packard, a London judge ruled on Tuesday.

The decision, which had been delayed several months after the death of Mr. Lynch, was a long-awaited development in the legal fight over Autonomy, the software company he sold to Hewlett-Packard for $11 billion. Hewlett-Packard later accused Mr. Lynch and others of fraudulently inflating the company’s value.

The amount was far less than the $4 billion sought by Hewlett Packard Enterprise, a successor company to Hewlett-Packard. “I consider that HP’s claim was always substantially exaggerated,”
