So what happens if you are looking through your mail and you see a new bank statement from a bank that you don’t recognize? What if the name on that account is your significant other’s? Sometimes a partner will even deny the existence of the new account. Cheating partners will often create new bank accounts to fund their naughty escapades. It’s easier to hide these actions by using a hidden bank account than to risk getting caught with a shared account. You should be concerned if you see new bank accounts appearing.
