Register marriage is very required.People even perform register marriage even after the traditional marriage.
This sentence prove by one examples.
One of my friend's sister is got married.But unfortunaly that boy is effected by cancer.He cannot survive more than one year.He is working in India railway.After his death the space is empty and according to rule of Indian government this post it given to first its relative.As she is wife she apply for that post but they Demand the proof of marriage.So that they verify is it she wife or not.At that time he has no register marriage proof.she face a lots of difficulty to get that post.that's why register marriage proof is necessary.
It is now neccesery requirement.Many office are demanding this as relation proof. Govt. has a special department just go with proper documents and it takes few times also .
Even I have to register for the marriage......but the catch is you have to register from the place where your marriage was conducted.it is better to contact a marriage registrar.....they would manage everything....
Oh sasi, Your marriage is performed by Arya Samaj, Thats great. But the arya samaj people wont accept if the couple come without date of birth certificate or tenth class certificate.
