Do not marry in a 498A or an alleged raped/harassed woman's family. The marriage certificate should say that NO dowry was given or taken during the marriage. Make sure the provisions of The Dowry Prohibition (Maintenance Of Lists Of Presents To The Bride And Bridegroom) Rules, 1985 are complied with. You need to ensure that the list of Gifts (‘Stridhan’) is signed by the couple along with 2 witnesses from each side. This should be recorded as a video. Do Not marry in the family where people are involved in illegal/fraudulent activities.
