Hi, as mentioned above, you can have your marriage solemnized under the Special Marriage Act, 1954. Few important points for you to note would be:
Before solemnization of your marriage, you need to serve a notice of your intention to marry in writing in the form specified in the Second Schedule of the act to the Marriage Officer of your district. (Where either of the parties to the marriage is residing.) Note, if you don't marry within 3 months of the notice being served, you'll have to have another notice issued.
The purpose of the above exercise is to allow someone else to make an objection to the intended marriage before the lapse of 30 days from the time of the notice being served. However, the objection will only be valid if the marriage is in contravention of any of the grounds given u/s 4 of the special marriage act. Click to check grounds.
Also note, if someone unnecessarily objects to your marriage, the court may direct them to compensate you and your spouse in the form of damages.
