I have two daughters and in the school records etc. I have changed their surname. Recently when I went to a bank to get an account opened for my daughter, since she is a minor, being the gurdian I was asked to show my residence proof which I did but since the surname was different, they wanted a proof of relationship!!!. One guy even advised me to get a gazzete issued or some sort of affidavit stating that I have decided to change the surname of my daughter!!..Even though the birth birth certificate I have for one of my daughter it has he name (with surname changed) and my my wife's name as her parents, the bank officials refused to consider that as a relation proof...Is this correct or strange? Is it madatory to have an affidavit / gazzetes filed/confirmed for such case? If yes, pls suggest how this can be done. I am currently residing in Pune and both my daughters were born in Delhi (Birth certificate is issued by MCD Delhi).
