ET has obtained court documents showing that the 14-year-old star's older sister Shanelle applied for guardianship of Ariel, alleging that the sitcom actress was a victim of both physical and emotional abuse at the hands of her mother, Chrisoula "Crystal" Workman.

The documents claim that Ariel "has been the victim of ongoing physical abuse (slapping, hitting, pushing) and emotional abuse (vile name calling, personal insults about minor and minor's height, attempts to 'sexualize' minor, deprivation of food, etc.) for an extended period of time by the minor's mother, Chrisoula Workman."

The papers also allege that Ariel's father, Glenn Workman, is "estranged and incapable of properly caring for a minor."

Shanelle tells the court that she should be deemed guardian because Ariel's mother receives checks for her work on Modern Family and controls her financial accounts.

A source close to the family tells ET that Arial had been living with her sister, who had recently reconnected with the family. Ariel's brother, Jimmy, denies the abuse allegations.

Last month, Ariel tweeted somewhat cryptic messages providing insight into her domestic drama, including, "ALWAYS be strong. Stand up for yourself" and "Love my siiiiissssttterrrr. <3 :D"

Winter's mother has spoken to People, denying the allegations: "It's all untrue, it's all untrue," she declared. "I have my doctor's letter that my daughter's never been abused. ... I have stylists' letters that she's never been abused."
