or for licensing an existing foreign (out-of-state) entity to transact business in Wisconsin.

The person or persons forming the business have the responsibility of selecting the type of entity to use. The department cannot offer legal advice; accordingly, you may want to consider consulting your own legal advisor in making this decision. It is not mandatory to engage an attorney to prepare and submit your organizational instrument for filing.

Our examination of your organizational instrument is limited to determining the availability of the name selected for the entity and in ascertaining that the document sets forth the minimum information and satisfies the general filing requirements of the particular statutory chapter under which it is formed.

An entity created under one chapter of law may, or may not, be convertible to a type organized under a different chapter. Changing from one type of entity to another may entail filing fees and other complications.
