A Wisconsin single-member LLC operating agreement is a legal document used by a sole business owner to establish the purpose, internal procedures, and policies of the company. Although it is not required in Wisconsin, implementing an operating agreement allows the owner to protect their personal assets from business liabilities, such as bankruptcy or legal claims. Without this document in place, the company would also be subject to general state rules governing LLC operations. The operating agreement also covers provisions regarding meetings, voting, succession, and dissolution.
