Father aged 85 years has 3 name , example Mr. A. B. C. Desa. . Birth certificate in Pune mentions it. DESA IS THE SURNAME.
Marriage not in civil court but religious certificate mentions A.B.C. DESA in mumbai
MOVED TO MUMBAI decades ago.from Pune .
He has been known as C DESA by all. In certain documents bank it's MR A. C. DESA. All due to convenience. He signs as AC DESA
3 children all married ,born in mumbai have the MR. C DESA ON the birth certificate. And mostly all other docs , passport etc same issue.
the middle name B was never used , I guess it was a long name nd he always grumbles about it.
There are no spelling mistakes in any name or surname recorded.
Its indeed a Herculean task to change all documents with all departments , Do we need to ...? If not What 1 document will suffice. Affidavit registered declaration.. And is it valid life long in case gov departments hav to ever ask for birth certificate etc proof should my father be no longer alive..
Thank you
