(MoneyWatch) Financial infidelity is not as common as you might think, with 92% of Americans saying that they never hide the details of their financial lives from a significant other.

Roughly 45% had secret savings accounts; 38% had hidden checking accounts. Perhaps predictably, 18% of respondents said they had a financial secret, but they weren't going to tell what it was.
