What happens if you get a subpeona and do not show to court?

You get a default judgment which will eliminate the consumer's right to defend one self (apparently this is what the banks' attorney will make you believe and a judge will usually go with it unless you stand up for yourself and not get intimidated by the banks' attorneys)

The above is not accurate. A default judgment might be entered if you fail to go to court on a SUMMONS and Complaint. A SUBPOENA is a court command to appear in court in someone else's case to either testify or bring documents that are to be used in evidence. If you get a SUBPOENA to appear in court on a specific date and you do not go, it is possible the court will hold you in contempt and perhaps issue a bench warrant for your arrest in serious cases.

Do not confuse a SUMMONS with a SUBPOENA. They are two different types of court process used for two different types of court actions.
