Urgent Advice

[creative17]

Court hearing for a Time Order application (joint application) one to ill to attend, medical evidence and covering letter supplied requesting re-list hearing to allow both to attend. Court did not advise I would still need to attend, I was led to believe the hearing would be re-listed as they said we both had to attend the hearing. Judge struck out our application and awarded against us. CCJ awarded due to non attendance at court, medical evidence was provided for second defendant.
This seems really unfair as we where mis-informed now both have a CCJ.
What is the best way - apply to set aside the judgement or variation order as judgement was made forwith?
Any advice appreciated
