Thanks
.
Just to clear that my mother always used her given name plus surname. So all her documents have the complete name. Its just a fault in my documents that her name is always mentioned only as given name in my entire documentation.
In this case i hope an affedavit would clear the confusion. Thats why i haven't let her apply for her passport yet so that if required , we can remove her surname while apllying for her passport by publishing name change in the newspaper - procedure for name change in Punjab india so that mine as well her passport have the name match.
Kindly suggest and thanks again for your help..
