Obtaining a birth certificate is mandatory for every child born at home or in hospital. The registration for birth certificate must be made within 21 days of birth. Though it is too late in your case, the birth certificate for a child with 12 years can be obtained.
Do visit your municipality office where the birth happened. Take the necessary forms to be filled and If you are living at the same place please contact the women and child welfare workers in your area to provide proof for the birth and also you may need the attestation of five neighbors who are senior citizens.
If you are living in a village or the birth place is a village, the concerned village revenue officer can provide you the attestations required and you need to provide a legal document in the form of notary stating that you are the parents and the time and place where the child is born and must be attested with a lawyer. With all these proofs you can apply birth certificate at a municipal office which has a separate section of Registrar of births and deaths by paying concerned fee.
The certificate of birth can be obtained after days after application.
