25% of couples have separate accounts

Some 25 per cent of couples in the UK keep their current accounts separate.

New research from Prudential has discovered that one-quarter of partners prefer to look after their own finances and this could lead to problems if people are trying to hide debts.

The topic of money in general was found to be the third most likely to cause a row, which highlights how it continues to be a divisive issue among Britons. The only thing people argue over more is family (33 per cent) and household chores (27 per cent).  

As well as having unique current accounts, 30 per cent also keep their savings accounts separate, while 23 per cent prefer to look after their own investments. 

Another issue that isn't up for discussion is retirement. The study found 19 per cent of couples over the age of 40 haven't talked about their post-work plans in the last five years, while 11 per cent have never spoken about their situation. 

Vince Smith-Hughes, retirement expert at Prudential, said: "For any couple, discussing and agreeing on the best retirement income options for them is as important as keeping their day-to-day finances in order. 

"A joint conversation with a financial adviser or retirement specialist could be an important step in ensuring that the right pension-saving decisions are made, so that both partners can enjoy a comfortable retirement."

He added it is all too easy for couples to put important conversations about finances to one side, but this is not the best way forward. Mr Smith-Hughes stated avoiding the conversation will simply lead to a "bigger issue in the long term". 

Couples should make sure they have full and frank conversations about their finances, as this is the best way to make sure they do not end up battling debt problems. However if they do need help, speaking to an expert is advised.
