(2) When, pursuant to law, territorial jurisdiction or venue of any action or court proceeding, civil or criminal, except those proceedings brought pursuant to chapter 210 or 211, is in that particular county, then the territorial jurisdiction or venue shall be in that portion of the circuit, or either, in which the factor, or factors, determinative of territorial jurisdiction or venue in the county, exist, arose, occurred, are committed, were taken or failed to be taken;
