1. As per the Births and Registration Act of 1969, all births should be registered before 21 days (60 days for NRIs). The record would be available with the Sub-Registrar of the ward for a year before going into the official record and the name has to be registered before the person attains 15 years of age.
2. The Chief Registrar of Births and Deaths and the Director of Health had issued directions permitting the respective municipal bodies or mandal offices to issue BCs provided sufficient evidence is given. This ‘one-time relaxation' was given as rules do not permit such a certificate to be issued once a citizen reaches 15 years of age i.e after 15 years of age. This ‘one-time relaxation' with ample Paper Publications throughout India expired on 15th. Aug. 2011.
Hence the remedy to your presented brief are only as follows;
A. Birth Certificate cannot be changed even under Writ jurisdiction now.
Hundred s of municipal corporation pan India had in fact written to the Centre four years ago (near about in 2007) to consider removing the 15-year time limit for a Birth Certificate to be issued and allow it to be obtained till the age of 35 but there has been no response till date from Centre.
B. Suggest your client to approach jurisdiction Court for legal change of name and once Ordered approach Gazette Office and get same Gazette Notified (ask him to take dozen copies of publications for lifetime usage) and make changes in all his public documents and produce the same before appropriate Foreign Authorities.
