In an ex parte divorce case, after the respondent's application to set aside the order was dismissed, the focus shifts to evidence. The court requires the petitioner to present witnesses, though there's no fixed number; your lawyer will advise based on the case specifics. Witness affidavits need to be drafted according to the situation. Following the completion of evidence, arguments will be heard before a decision is made. The defendant can challenge the court's decision, but stopping the ex parte proceedings at this stage may be difficult.
