Relating to: determination of where a defendant resides or does substantial business for purposes of venue.

SB 226 clarifies venue rules for civil cases involving corporations. It creates two new statutory provisions: Section 801.50(3c) prevents courts from considering joined parties (like insurers under §803.04) when determining proper venue, and Section 801.50(3g) defines where corporations "reside" (place of incorporation) and where they "do substantial business" (only their principal county). This directly affects businesses and plaintiffs in civil lawsuits by limiting venue options based on corporate structure. The bill aims to standardize venue decisions for corporations, preventing claims of business activity in multiple counties to influence court location.
