I don't think it as easy as that. From my experience during the court process I was never able to change the court date, even when it was a life and death situation. I think courts just say that as a formality.
In my experience it was his barrister on holiday in Bahamas these dates, mine attending a funeral this date. I just got what was left...I took it! I wanted it sorted and so adapted to their ridiculously LONG wait
