Question: I took off child support and let my daughter go live with her dad. He has since then, hidden our child. What do I do??
Answer: Ref your question. Your issue is getting complex as the time passes. To be precise, the best option left for you is to seek court intervention through an Attorney of your local jurisdiction who may submit the whole facts of the matter and seek intervention of law.
Children cannot in any way split from each other just for sake of avoiding child support. You cannot be stopped to see, visit or meet your daughter or to keep her with you.
