The Game of Thrones alum came to a temporary custody agreement with Jonas in October, but is now preparing to resume the proceedings in court.
Four months ago, the singer filed for divorce from the Game Of Thrones star after four years of marriage.
The Game of Thrones alum had sued the singer after he allegedly broke his agreement to return their children to England in Turner’s care.
The Game Of Thrones star posted a “fearless” bracelet on her Instagram story, which happens to be the name of Swift’s second studio album.
