You may trust the one you love implicitly - but that doesn't stop you from snooping to find out more about their finances.
This is the impression given by a new survey by credit monitoring company CreditExpert, which found that more than a third of those in a relationship read their partner's emails, bank statements and private correspondence.
Those with the most money in the bank are most likely to spy on their loved ones, the research suggests - half of the very wealthy people surveyed admitted checking bank statements for wayward spending.
Couples who are actually living together may have made a clear statement of trust by choosing cohabitation, but they are also suspicious, with sixty per cent conceding that they do read their partner's personal financial correspondence.
"As credit management becomes more important, there is increasing potential for relationships to founder on a lack of trust. People can be tied together financially without knowing that much about each other's finances," Jim Hodgkins, managing director of CreditExpert, told the Guardian.
Mr Hodgkins warned: "If you get a joint mortgage or have a financial relationship, you will be tied together in the eyes of lenders."
East Anglia was the region most populated by financial snoopers - 40 per cent of those surveyed in the area said they had spied on their partner's financial situation.Click here for mortgage advice to test how much you trust your partner.
