Section 29(1) of the Hindu Marriage Act provides that a pre-Act marriage between Hindus, "which is otherwise valid", is not invalid "by reason only of the fact that the parties thereto belonged to the same gotra or pravara or belonged to different religions, castes or sub-divisions of the same caste". It does not cure omitted ceremonies or relationships within prohibited degrees or sapinda limits.
