Miss San Antonio Domonique Ramirez, 17, received a temporary restraining order by a judge in Bexar County on Feb. 8 that allows her to keep her crown until her claims can be heard.
Ramirez, who wants to compete in the Miss Texas pageant, claims her parents were informed on Jan. 25 that she had been replaced by 2010 runner-up Ashley Dixon.
Pageant board members told ABC News that Ramirez, failed to live up to pageant rules and had packed on some pounds since her coronation last year.
"My future shouldn't be ruined over this," the beauty queen, a competitive volleyball player who led her high school team to a state tournament, told an ABC affiliate in Texas. "They're bringing up things that were in the past."
"She was doing a photo shoot and asked to wear her wardrobe from the competition, but it did not fit her," spokeswoman Linda Woods told the network. "I told her we need to get you on an exercise program. We need to get ready for Miss Texas, just like any elite athlete."
Officials also complained that Ramirez was late for events, completely missed some scheduled appearances and sometimes showed up holding hands with her boyfriend.
The raven-haired beauty queen's attorney told the network the allegations were "total lies."
Lawyer Luis Vera of the League of United Latin American Citizens claims pageant officials failed to live up to their responsibilities by providing Ramirez, who was just 16 when crowned, with chaperones and transportation to appearances. He claims Ramirez is still the rightful Miss San Antonio.
A court date is scheduled for Feb. 16.
