The 15-year-old teenage star's mother Chrystal Workman was stripped of her parental rights in October after the Winter claimed she was being physically and emotionally abused by her parent, reported E! online.
Her 34-year-old sister Shanelle Gray was handed temporary custody and Winter recently insisted she had been enjoying "more of a family life" since moving in with her older sibling and her husband.
Workman has been fighting to regain guardianship of the teen and the case returned to court recently when she asked a judge to force the actress to attend joint therapy sessions in a bid to repair their fractured relationship.
He told Workman, "It's a work in progress... There's been no advancement in terms of reunification."

Judge Levanas then scheduled the case to go to trial this October, much to Workman's dissatisfaction.
Gray's lawyer Michael Kretzner said that his client is open to settling the case out of court, although she is willing to take care of Winter for as long as necessary.
