There is a general acceptance that, during the first few months of the new year, divorce rates rise. There is plenty of data to back this up, but the more complicated question is "why?" Why does this happen every year? There could be many answers, and not every divorce case may have just one. It could be that the stress of the holidays causes a couple to divorce; it could be that the winter weather brings a couple down, spurring a divorce; it could be that New Year's makes a spouse realize that his or her life needs to change, and a divorce is the right way to go about this new chapter.
In any case though, from January to March, the divorce rate rises. According to a study by FindLaw, between 2008 and 2011 the number of divorces jumped in January, with the fluctuation continuing through February before hitting it's pinnacle in late March.
In addition, the study found that web search terms relating to divorce also jumped during this period. "Divorce," "family law," "child custody" and other related terms saw a search increase of nearly 50 percent from December 2010 to January 2011.
Of course, this doesn't mean that your marriage is destined to end in divorce simply because the calendar switches from December to January. Should you and your spouse decide to file for divorce though (whether the filing occurs in February or June or October) you need to prepare your case and get your necessaries in order. Consulting with an experienced divorce attorney is the best way to ensure you are going about these things in the right way.
