Cross motion question

Yes and you need to file your opposition / response to the substance of your ex's affidavit / certification with the court and your ex's lawyer by the date set forth in the cross application or the relief being sought by your ex will be viewed by the court as unopposed and the court can grant the relief sought by your ex. You do not have the right to simply expect to walk into court on the return date and tell the court why you disagree with her cross application. If you want to represent yourself in a court matter, you are bound by the court rules and the deadlines for filing purposes. Your opposition to their cross application MUST be filed with the court and the other lawyer at least 8 days prior to the court date. If the court date is next Friday, then your opposition papers to their cross application ( a certification under oath as of you were testifying on the witness stand) must be submitted to the court and to the other lawyer NO LATER THAN this Thursday. If you fail to file your opposition papers timely, presume that the other lawyer will ask the court to view their application as unopposed and ask the court to grant them the relief sought.
