Kellie Chauvin separated from her husband on May 28, the day before he was charged with third-degree murder and second-degree manslaughter for the death of George Floyd, according to the filing.
Chauvin said in the filing she wants to change her last name, among other requests.
Chauvin also requested full rights and titles to the couple's properties in Oakdale, Minnesota, and Windermere, Florida, located in the Orlando metropolitan area.
She has two children from her previous marriage, the Twin Cities Pioneer Press reported in a profile of Kellie Chauvin in 2018.
In 2018, she competed for Mrs. Minnesota, a pageant for married Minnesotans.
Her platform, she told the Pioneer Press, involved buying groceries for police officers and military members, rescuing animals and volunteering with a nonprofit for Hmong women, an ethnic group from southeast Asia that she belongs to, who recently moved to the US.
