Yes, he is on the birth certificate. Obtaining the school records, health records, etc. from when he had custody of the child won't be a problem either. You mentioned proving neglect, do you think it would carry sufficient weight if we were able to prove there's recreational drug use such as marijuana or ecstasy? As for proving the mother has moved residence so often, any suggestions on how to obtain that information since I suspect she's been using her mother's address as the address of record for the child's school? Also, he's provided child care for the child since birth and the cost has never been shared, would that be considered a gift as well? The money he's provided has never been cash and often either a bank to bank transfer or check (which states the purpose of the money), could that still be deemed as a gift?
