Get notarized affidavits from other people that knew the situation and appeal the decision.How do get your kid back when your ex husband lied to the judge?
Did you tell the judge yourself what happened? If you appear in court and state your side of the story, its obvious you care, or you wouldnt be there.
all you can do is prove that you didn't that he just took her. this happen to my sister did you tell the daycare about him taking her if so ask if they can record a message or put it in writing what they remember you saying (her dad took her to see her grandparents should be back soon) so did you say this on a message on a phone or something..
