The vast majority of claims settle out of court either at a mediation or court appointed settlement conference or in the lead up to the hearing. It is very rare that a matter will proceed to court.
Where matters proceed to court it is usually because of a dispute as to how much a claim is worth. Such a claim will normally take only one or two days to be heard and judgment will be given within a very short space of time, usually a week.
If you are not well enough to attend court, then your evidence will be taken at your home or hospital. In most courts your evidence in chief will be given by Affidavit.
