The World Crunch has interviewed Ajit Singh, the director of the Hatfield India detective agency.
Here is what he had to say:
"My clients want verified information about their children's future spouses, things like their financial situation and overall reputation."
"Before, families who lived in villages knew each other well, and could count on reliable information brought by local intermediaries. Now, newspaper and online classifieds serve as the intermediary. There are more opportunities for marriage, but they are less reliable," says Singh.
He also explains "In India, the new wife must go and live with her in-laws according to tradition."
"And it is the mother-in-law who will have a real impact on the life of the young bride. She will want to take care of her and give her orders. We check that she doesn't have a loose temper, we look at how she treats her help or her driver, for example, or if she has a habit of breaking dishes when she is angry."
