Name addition to Birth Certificate

My sister was born in Vashi, Navi Mumbai in 1995. As my parents got relocated to Kerala immediately after that, her name was not added to the birth registration. Due to unfavourable situation, my Parents were not able to go back to Navi Mumbai and get the name added. Now we tried to get her birth certificate issued and got it without much hassles. But the birth certificate does not have her name and the authorities say that as 15 years have passed after the birth registration, they can't add the name now. As she's going for her studies abroad, the birth certificate with name is a mandatory document. This is very urgent now and can affect her career. Please let us know if anything can be done about this. I read a Times Of India article which says the State government has issued instructions to the Municipalities to issue fresh birth certificates with names in such cases. But the Navi Mumbai Municipal Corporation denies this. https://timesofindia.indiatimes.com/city/kolhapur/Age-no-bar-to-get-name-added-to-birth-certificate/articleshow/48474810.cms
