You start the divorce process by issuing a divorce petition. You then follow various stages before the marriage is finally dissolved, with the pronouncement of the Decree Absolute.
The length of the normal divorce process is dependent on where you live and can take up to 4 months to get a Decree Nisi and 12 months for the Decree Absolute. The average time for a divorce to reach the Decree Absolute stage in England and Wales was 33 weeks in the first half of 2014 according to the Office For National Statistics. However, steps are now being taken to centralise the divorce process rather than the parties choosing the Court themselves. This should speed up the process for divorce. The centralisation is expected to take effect from October 2015.
