The number of jury members for a "real estate" trial can vary from zero to 12, depending on the jurisdiction and kind of case. In a case that is before a court of equity/chancery and/or for certain kinds of lawsuits (such as a case of "specific performance"), no jury may be allowed, or a jury may be allowed but only for a limited number of issues. In a case "at law" (such as a "simple" breach of contract claim), it depends on what the laws and court rules are. It may be a 6-person jury, or 12-person jury. It is a jurisdiction by jurisdiction matter. If it is a criminal trial, other rules may apply. Again it is jurisdiction by jurisdiction, including state or federal trials.

It depends on how many people live there.
This depends on the state in Georgia there are 12.
