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."

Relationship tips from life coach, Sophia Davis.
"Sometimes couples find it easier to turn to friends rather than their other half when it comes to talking through problems. Turning your back on your partner during a stressful time can be damaging to your relationship, as it can lead to feelings of rejection and frustration. Communicate with your partner and turn to each other. This builds the confidence and trust you both need so you can discuss heavier and potentially stressful topics when they arise."
"While most people think that intimacy has to lead to sex, think again, because it also enables you to both relax and reveal your thoughts and feelings. Feeling close to your partner helps you solve problems as a team and helps you be open and honest. Intimacy gives your partner a chance to support you and in return, you are more likely to support them when they are stressed."
"If you are unkind to yourself and picking on yourself for choices you think you should have/shouldn't have made, by extension you will be unkind to your partner. If you want to maintain a strong and healthy, being kind to yourself an your partner is one of the first places to start."
"It's easy to get overwhelmed with daily activities and workloads, meaning little time is left for anything else. The more time spent on these things, the less time is spent with your partner. Work stress is top factor for causing friction in a marriage, so don't be a workaholic - stay in touch by phone, email, text messages. Cut back on your schedules if they aren't essential and prioritise a certain amount of 'us' time per week."
