Proving perjury during cross

Defendant in his initial cross of partition claimed he was always living in the house he had broken into. He had not taken this defence earlier so I did not produce documents about this. But I have now received a court settlement with his landlord at the same time as he claims he was living in suit property. I had not filed this earlier as I did not anticipate he could lie on the stand. Can I now seek to add photo copy of this court order to documents at this stage. I do not have the original order though this pertains to 2012 and do not know if as not being party to that case I am entitled to certified copy of that order. I am fighting my own case because I cannot afford a lawyer.
