Celebs started the trend for pre-marital background checks moving into the realm of the first three months – Britney Spears reportedly asked her new boyfriend Dave to sign a confidentiality agreement and pass a background check before taking their relationship further. But what are private investigators looking for? When conducting a pre-marital background check, we verify Identity, Address, Financial Stability, Employment, Property, Marital Status, and Moral Character. Some people think that it’s paranoid. I think it’s crazy that some people do less research on the history of a person we let into our homes (and vaginas) than the condition of a used purse on Ebay.
