Registration of births were not regularly followed earlier. In such situations, the school records, the cumulative record, 10th/12th or degree certificate would be accepted as the evidence of the date of birth. Please check whether you have such a copy.
Now you have to apply in person to the
MCF Office Faridabad
Gurgaon - Faridabad Road, BK Chowk, Faridabad, Haryana 121001.
The officers would check their records and issue a 'Record(of birth) Non-availability' certificate.
Please meet a good lawyer with this certificate, any school certificate and ID proof and the lawyer will help you to get a birth certificate issued via the court (after verification)
If this does not help, you can contact the office of the District Magistrate or Collector or the JMFC (Judicial Magistrate of First Class) to issue you a Make order certificate.
You would need 10th or SSLC marks card, an affidavit from your parents or elder siblings stating your date of birth, your family ration card. Please have your photographs, ID proofs etc and then contact the administrative staff of one of these offices, they would help you out.
Please contact the Municipal office staff personally, they would be able to guide you as they would have faced this situation many times.
