Laurie... you said your niece was never married to the father, does he have any legal right to the child, any visitation/custody rights? If he doesn't, then she shouldn't need his permission to take the child out of the country. And, if the child's birth certificate doesn't list him as the father, then that should be "proof" enough that there isn't a father who needs to give his persmission. Does that make sense? I think I'd be talking to my lawyer, not looking for a missing father figure. Perhaps a legal document that lists her as the ONLY legal parent would be all she needed.
