You may be held in contempt of court.
You may be issued a body attachment or bench arrest warrant to appear before the judge.
You may be fined by the judge for having no reason to fail to appear.
You may begin the start of a record that will impact your future regarding credit, loans, real estate purchases, job searches, etc....
Wise up. Follow the court order. Tell the truth.
If you are sued and do not show up, you lose. If you receive an order like you describe and do not show up, you could be arrested and held in contempt. It is not wise to ignore a court order.

It is much better to go and to explain your situation than to simply turn your back to the court order. If you go, you have some chance. If you don't show up, you can be held in contempt, an arrest warrant can issue, etc.
