I am going to explain the process for Delhi and particularly East Delhi Muncipal Corporation (EDMC).So, if your child birth happened in East Delhi, then you need to apply to East Delhi MCD for addition of name in the birth certificate.Documents Needed -Original Birth Certificate (for verification only)Photocopy of Original Birth CertificateApplication on plain paper (Child Name, Gender, Date of Birth, Place of Birth, Mother Name, Father Name and Address)Aadhar Photocopy of Mother and FatherSubmit the above documents in East MCD office situated behind Karkardooma Court, Delhi.No fees is charged.They will give the receiving on back of your original birth certificate and you will be asked to come back after 15 days for collection. You can also download the birth certificate online.I submitted the application today and will update after 15 days whether things went as per schedule.Edit - The name of my child was updated around 10 Jan 2023. And I was able to download the e-certificate from the East MCD website by clicking on this link -http://111.93.47.72/csbedmc/rbd/...You have to pay Rs. 21 for downloading the certificate. No need to get the physical certificate.CheersSg
