One of my friend marriage is love marriage. She is basically from Karnataka and she is temporally staying in Bangalore
and working in electronic city. The groom is from Coimbatore and presently he
is working in Australia. Both the parents are not accepting their relationship
and opposing very seriously for getting married.
He is secretly visiting Bangalore from Australia for two week holiday and they have decided to do simple and secret Arya
samaj marriage and registration anywhere in Bangalore. Same time after
completing Arya samaj marriage formalities they wish to apply spouse visa for
Australia immediately. SO they need valid marriage certificate for visa
process. Since she is working in Bangalore electronic city and they prefer to
do Arya samaj marriage in Bangalore electronic city area or anywhere in
Bangalore.
we approached the electronic city sub registrar for Arya samaj marriage  registration and we cannot able to get any information from registrar. But they said local
address proof  is mandatory for Aryasamaj marriage  registration in Bangalore. Also they indicated that Arya samaj marriage process will be done in mandir only. So I want to get clarification about Arya samaj marriage and registration procedure in Bangalore.
