Caitlyn Jenner has applied to make her name and gender transition official, but she has requested privacy, claiming she has received threats.
The Olympic gold medallist who was born Bruce Jenner filed a name and gender-change petition on Tuesday in Los Angeles. She is seeking a private hearing to officially change her name to Caitlyn Marie Jenner and gender to female.
Jenner, 65, is seeking the change "to better match my identity," the petition states.
It was released so a judge could consider Jenner's request to file portions of the application under seal.
Some details in the released petition were redacted after Jenner's lawyers sought to keep certain personal details private, citing concerns about threats made against her.
"Although public support for my transition has been overwhelmingly supportive, I am also receiving unwelcome negative attention from private citizens, including threats of bodily harm," Jenner wrote in a sworn declaration.
She signed the document using her birth name, William Bruce Jenner, last week.
Jenner won a gold medal in the men's decathlon at the 1976 Olympics and was married to Kris Jenner, mother of the Kardashian sisters, for more than 20 years.
Jenner appeared on their reality series, Keeping Up With the Kardashians, and has documented her transition on her own reality series, I Am Cait.
Los Angeles prosecutors are still considering whether to file a criminal case against Jenner over a crash in February on the Pacific Coast Highway that left one woman dead.
Jenner's vehicle crashed into two cars on February 7, pushing a car driven by Kim Howe in to oncoming traffic. Howe, 69, died after her vehicle was struck by a Hummer, and her stepchildren are suing Jenner for wrongful death.
Sheriff's investigators determined that Jenner was travelling at an unsafe speed for the road conditions at the time, and there was enough evidence to support a charge of vehicular manslaughter, the department said last month.
