Dear client, 

In the instant case, it is the Special Marriage Act, 1954 that would be applicable since this is the law that solemnizes marriage between parties irrespective of their caste, religion and nationality. It is under the Special Marriage Act that the court marriage will result in a valid marriage between you and your girlfriend.  

It is not necessary for the parents to be involved in the marriage. 

The requirements of the marriage are that it should be done voluntarily by male who is above 21 years and the female above 18 years and the solemnization requires it to be done in the presence of two witnesses who would validate the marriage thereby making it legally binding. 

Since she is a foreigner, it is important that she gets a valid NOC which is attested by the embassy which is of utmost importance in the instant case.

Along with the NOC, her visa and passport are also essential documents that are proof of her age and identity. 

There is no necessity for renouncing her foreign citizenship and for acquiring the OCI, it is important that her marriage has been registered and subsisted for at least 2 years continuously. 

I hope this answer helps. For any further queries, please do not hesitate to contact us. Thank you.
