In case a marriage between an Indian and a foreign national is to take place in India, the marriage has to solemnize under the Special Marriage Act of 1954.Generally it is required to file a notice of intended marriage with a Marriage Registrar of your choice in India. That notice is required to be published for the stipulated 30 days. At the end of the 30 days the Marriage Registrar is free to perform the marriage.If one partner is residing in a foreign country then the partner who is resident in India will have to fill out the “Marriage Notice” collected from the Marriage Registration Office of his/her choice in India and send it to his/her partner in the foreign country who will also have to fill it out. This “Notice” should then be sent back to the partner in India who will have to re-submit it at the Marriage Registration Office. After the stipulated waiting period of 30 days the marriage can take place in India.
