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.
