You have every right to custody of your children. The grandparents do not have the right to decide what they want,the court has not gave them custody therefore they are keeping the children against your will. Well I see they have guardianship,guardianship is just tempory until the absent parent files for custody. Your chances of custody is good,and I would inform the court that the grandparents have never tried to get in touch with you about their mothers death. Good luck!
