You need to inform the court that you have witnesses. Or if they have signed declarations, you can serve them (fax or personal service other than yourself) over the weekend and take the proof of service to the court on Monday. The judge will decide to either give the other party more time or will deal with it at the hearing. It is a good idea if you take a lawyer with you.
