Civil marriages, also commonly called ‘Special Marriages’ or ‘Inter-religious marriages’ do not depend on the religion of the couple. Instead, the marriage happens under the Special Marriage Act where a couple practicing a different faith or religion have the right to get married in India.(( The Special Marriage Act, 1954.))
To get married under this law, you need to figure out if you and your spouse are legally eligible to get married. For example, you need to be over a certain age to be able to get married and you cannot have another living spouse from whom you have not been divorced.
