One-in-seven couples over the age of 40 have never discussed their financial situation.
This is according to new research from Prudential and the main reason for this is that people are worried about having an awkward conversation.
Some 15 per cent of those questioned said they feel uncomfortable with the topic being out in the open, while money worries was found to be the third most likely topic to cause an argument – behind family disputes and household chores.
Vince Smith-Hughes, retirement expert at Prudential said: "Money can be a tough topic to discuss at the best of times. Many couples prefer to steer clear of conversations about finances, and especially discussions about longer-term issues like retirement."
However, he added the old adage that honesty is the best policy applies here, as couples should never shy away from these types of conversations.
In terms of what is the financial subjects most frequently discussed by couples, everyday living costs (60 per cent) came out on top, followed by household bills (52 per cent) and home improvements (34 per cent).
