All couples argue, but what are couples fighting about the most?

According to a recent survey from the American Institute of CPAs, money is the most common reason married or cohabiting couples fight.

Of over 1,000 American adults polled in a national telephone survey, 27 percent of participants said that disagreements over finances were most likely to erupt into an argument -- not children, chores, work or friends.

The survey also found that couples average three arguments a month about financial issues.

Researchers believe that the conflict may stem from failing to discuss money on a regular basis. Fifty-five percent of those surveyed who were married or living with a partner said that they don't regularly set aside time to talk about financial issues.

For that reason, says HuffPost Weddings blogger and financial expert Jennifer Calandra, couples should have a financial conversation before they exchange their "I Dos."

"One of the biggest roadblocks we see is a lack of communication about finances, which seems to get worse as the years go on," she wrote in January. "Make it a point to establish your level of expectation from the beginning regarding communication. It will help significantly as time goes on."
