Wisconsin Statutes Property (Ch. 700 to 710) § 703.07. Establishment of condominium

(1) A condominium may only be created by recording condominium instruments with the register of deeds of the county where the property is located. A condominium declaration and plat shall be presented together to the register of deeds for recording.

(2) A condominium instrument, and all amendments, addenda and certifications of a condominium instrument, shall be recorded in every county in which any portion of the condominium is located, and shall be indexed in each county in the name of the grantor and grantee and the description of the condominium property that is located in that county. Subsequent instruments affecting the title to a unit which is physically located entirely within a single county shall be recorded only in that county, notwithstanding the fact that the common elements are not physically located entirely within that county. Subsequent amendments and addenda shall be indexed under the name of the condominium.

(3) All instruments affecting title to units shall be recorded and taxed as in other real property transactions.
