Why is the first week in January called “National Divorce Week”?

Web Searches for ‘divorce’ on GOV.UK are 55 per cent higher in early January than in early December (456 searches in first week of January compared to 294 in first week of December).

The government in 2013 introduced major changes designed to ensure that in future separating parents and couples will first consider using mediation to resolve the issues around divorce and separation – like splitting property or agreeing child contact times – rather than fighting over it in court.
