Glenn Workman filed papers Monday objecting to stripping his estranged wife Chrisoula of custody of the 14-year-old. His protest comes one day before a Los Angeles judge is scheduled to hold a hearing in the case.
Workman was described in an October court filing as being unable to care for Winter.
But he says he is financially and emotionally capable of caring for her. He acknowledges Winter has a strained relationship with her mother.
Winter has been living with her adult sister since early October, when a judge temporarily stripped Chrisoula Workman of custody amid allegations she had been physically and emotionally abusive to the actress.
