Although it's meant to be the season of goodwill and happiness, December is the month couples argue the most, with one in 20 doubting their relationship will survive past Christmas Day.
The study by Seddons found that one in five are already considering splitting up with their partner and blame money worries, entertaining extended family members and sharing the workload over Christmas as the main triggers.
Almost one in five admitted that they dread Christmas as they know it'll cause a string of rows with their partner.
Out of the 2,000 people questioned, the average couple argued four times a day - 124 throughout the whole of December. For some (23%), it became so bad, they decided to walk out on their relationship for good in December.
However, for 16% of those who split, they admitted that the separation was purely down to them wanting avoiding buying their partner a Christmas gift…
"The quest for a perfect Christmas and keeping everyone happy can often result in couples neglecting each other or just bad communication," says Head of Family Law, Deborah Jeff.
"By keeping a sense of perspective and being willing to compromise, your relationship needn't be a casualty of the season. Even something as simple as having planned some time for just the two of you once all the entertaining is over can support your relationship over the Christmas period.
"But if the issues are still there in the New Year, get specialist legal advice and consult a relationship counsellor before making any long-term decisions."
