Can the court issue a warrant for not responding to a summons in a civil case?
If a summons was issued then yes a warrant can be issued but I’m thinking that you might be confusing being severed with a statement of claim and a summons. Odds are the trial will simply proceed ex parte and a judgement will be entered against your husband. I’m not sure what you mean by court costs. If you are being sued it does not cost anything to show up and defend yourself. Yes lawyers cost money but you have a right to represent yourself which is free if not advisable. Still better to show up and defend yourself than to allow the train to continue ex parte.
