A real estate company is being sued by a home buyer of a house the real estate company had listed, and on which the real estate company had received a sales commission. The home buyer alleges the home is infested with ants. The real estate company had a report from an inspector that stated that the home had no ants. The real estate company has cross-claimed against the inspector (thereby bringing the inspector into the case). What type of information does the real estate company need to to prepare for litigation and how can that information be obtained?
