Application to have a county court order set aside

I had a judgment made against me last march I did not attend has I put a defense in but made no difference to the out come I was in debt management & currently be revue by the ombudsman there conduct over this matter what forms will I need or am I too late?

What valid reason do you have for a set aside ?
If you entered a defence and lost you must abide by the judgement order.

To expand on CurlyBen's answer (and I had difficult with the question) in order to set the Order aside you must have a compelling reason - bad service is a good one. Not liking the decision, the Court ignored you - not good reasons.

Then if you do get it set aside and reheard - what is your defense?

Just losing is not reason to appeal. What was the error of the court or error in service that is the reason to have it set aside.

It appears you knew about court date, made a choice not to appear, sent in some evidence, not sure how that was done. And lost, I see no reason to do anything further
