According to recently made public probate paperwork, a UK-based tycoon who perished in the OceanGate Titan submersible accident left his wife less than £100,000 in Britain after passing away without leaving a legitimate British will.

Shahzada Dawood, 48, lost his £76,958 UK inheritance to his Surrey-based wife Christine after he and his teenage son died in the June 2023 tragedy.

According to the documents, Dawood kept most of his wealth outside of Britain and had his home in Pakistan.

A tragic implosion of the OceanGate submersible near the Titanic wreckage killed five people, including Dawood and his 19-year-old son Suleman.

An hour and forty-five minutes into the dive off the coast of Newfoundland, the ship lost contact with the Polar Prince, its support ship.

Later, the wreckage was found about 3,700 meters below the ocean's surface, 330 yards from the Titanic's bow.

The accident also claimed the lives of French naval veteran Paul-Henry Nargeolet, 77, British businessman Hamish Harding, 58, and OceanGate CEO Stockton Rush, 61.

Since he passed away without a valid will in the UK, Christine Dawood was granted letters of administration as his legal spouse.

Mrs Dawood continues to reside in the family's Surrey home, where she received the modest British portion of her late husband's estate.

The billionaire businessman, who served as a trustee at the SETI Institute and worked with the Prince's Trust, had the majority of his considerable fortune held outside the UK.

Speaking to The Daily Mail, Christine shared her heartbreaking moment of realisation with her daughter Alina on the support ship.

"The moment we knew they'd found debris and there were no survivors, Alina and I went on deck. I turned to her and said: 'I'm a widow now.' She said: 'Yes, and I'm a single child,'" she recalled.

"We don't have graves for them," she added. "But recently we went to Singapore. The sea was warm enough for us to walk in and I truly felt them around me."

Suleman, a student at Strathclyde University in Glasgow, had taken his Rubik's Cube on the fatal journey, hoping to break the world record for solving the puzzle at the greatest depth.

Mrs Dawood had originally planned to make the Titanic journey herself with her husband, but their trip was cancelled due to Covid-19.

Suleman, who had developed a fascination with the Titanic after completing a 10,000-piece Lego model, took his mother's place on the expedition.
