Can anyone tell me how to file a motion to vacate a judgement? It is civil or small claims court.?

I had a company, midland funding LLC get a judgement against me in civil court without any knowledge on my part. I have lived at the same address for over ten yrs. so that isnt a factor as to why, but i was never served with anything, nor did i even know until yesterday when i recieved notice that they are taking my bank accounts.
