Charlotte Heppel, daughter of the late Peter Heppel QC, was hit by a car while crossing a road in the capital Bangkok, where she had been teaching English.
The tragedy is the second to hit the family in recent years. Her father, a circuit judge who spent the spent the majority of his legal life in Yorkshire and the Humber, died after a heart attack in 2004, aged 55.
Ms Heppel flew out to Bangkok last year with her boyfriend Greg O'Donnell. Her childhood friends Caroline Woollen, 25, and sister Amelia, 24, were already teaching there.
The accident happened in the Samutprakarn district of the city at 2am local time on Saturday, as Charlotte was on her way home with Mr O'Donnell.
The girls' father Tony Woollen, of Brough, near Hull, had been visiting his daughters in Bangkok when the accident happened. He said: "Greg rang us to tell us the news in the early hours. Obviously he is devastated and so are my daughters.
"Charlotte had known my girls from four or five years of age. They have been teaching there since August and she and Greg came in November. It's appalling, dreadful."
An actor and singer, Ms Heppel did a postgraduate Certificate in Education in Edinburgh after graduating from the University of Salford, where she studied performing arts.
She then taught performing arts at Longcroft School, Beverley, East Yorkshire.
A close friend, who didn't want to be named, said: "She was hilarious, she was really, really fun-loving. She had a lot of close friends. She enjoyed going out with people and she was always the highlight of the night.
"She wanted the opportunity to travel before she settled down. She was having the best time of her life there."
Ms Heppel's mother Jan, lives at North Newbald She also has a sister, India, and two brothers, Edward and Will.
