This article gives a good summary of the latest statistics, published about family courts, by the Ministry of Justice (MOJ).
Interestingly, the majority of of family law cases feature at least one litigant in person, which isn't surprising in the present climate. The person who starts the proceedings in court is more likely to be represented by a lawyer.
Whilst you don't have to have legal representation, from experience, those that don't are often confused about the court process. This has led to our local court in Oxford issuing guidance to help those without representation.
The Ministry of Justice (MOJ) has published its most recent statistical bulletin presenting statistics relating to family courts. The bulletin presents statistics on activity in the family courts of England and Wales and provides provisional figures for the latest quarter (January to March 2015) with accompanying commentary and analysis. The figures give a summary overview of the volume of cases dealt with by these courts over time, with statistics also broken down for the main types of case involved.
