Ariel Winter. (Adriana M. Barraza/WENN.com) 'Modern' star's mom fights abuse claim 'Modern' star's mom denies abuse claim 'Modern' star, 13, college bound 'Modern Family' pokes fun at itself

Ariel Winter’s father has filed an objection after his teenage daughter was placed in the care of her elder sister amid allegations of parental abuse at home.

The Modern Family star has accused her mum Crystal Workman of physical and emotional abuse, and the 14 year old's sister Shanelle Workman was subsequently appointed her temporary guardian.

The siblings' dad Glenn Workman has submitted legal papers objecting to Shanelle's guardianship, ahead of a court hearing into the matter in Los Angeles on Tuesday.

In the filing, obtained by TMZ.com, he states, "I am physically, emotionally, and financially capable of caring for my daughter, without limitation. No evidence has been produced that suggests any detriment to Ariel associated with my father-daughter relationship with her...

"I am a frugal and modest person with a moderate income who doesn't need Ariel's income to survive."

Glenn does not comment on the abuse allegations, except to say Crystal's relationship with Ariel is strained, and adds, "I believe Ariel has demonstrated a lot of maturity and is at an age now that she should have more control over her finances."

Meanwhile, Ariel's brother, Jimmy Workman, has also penned a declaration asking the court system to help mend the family's problems.

He writes, "I have never seen any physical or emotional abuse in the home of my parents regarding Ariel. I have seen normal mother and daughter arguments and banter back and forth but nothing more... My position is not to take sides with anyone, but to get this family back where it belongs."
