No special tax bill need give the name of any party owning or interested in any land charged and bound by the lien; and before suit the owner of any part in severalty, or of any undivided interest in any land charged by any tax bill, may pay his share separately, in which case his part or interest shall not be further liable in case of suit. All or any of the owners of the land charged, or of any interest or estate therein, may be made defendants in any suit, but only the right, title, interest and estate of the parties made defendant in any suit shall be affected or bound thereby, or by the proceedings therein. In case any owner of the land, or of any interest therein, shall be unknown, or a nonresident of the state, suit under this section may be brought against the owner separately or together with others, and the unknown or nonresident owner may be proceeded against and charged by giving notice, either by publication in a newspaper or otherwise, as in suit in the circuit court to enforce any other lien on land in the county. Every tax bill, and the lien thereof, shall be assignable, and any assignee may sue in his own name. It shall be sufficient for the plaintiff, in any suit on the special tax bill, to plead the making of the tax bill sued upon, giving the date and contents thereof, and the assignment thereof, if any, and to allege that the party or parties made defendant own, or claim to own, the lands charged, or some estate or interest therein, as the case may be, and to file the tax bill in suit. Special tax bills against different lots or parcels of land, owned by the same party or parties made defendant, may join in one suit; but a separate judgment on each tax bill shall be rendered, and execution shall be issued accordingly.
