A Minnesota single-member LLC operating agreement is used by sole proprietors to formally establish the ownership and internal structure of a limited liability company shortly after its formation. Even though LLCs are not legally required by Minnesota state law to implement an operating agreement, it is extremely helpful for a variety of reasons. In addition to protecting the owner from any financial or legal liabilities faced by the company, it also allows the owner to determine its own rules and conduct with regard to operations, membership, management, dissolution, and more. Otherwise, the company would be subject to Minnesota laws governing LLCs. The agreement should be signed and dated electronically or in the presence of a notary public for proof of validity.
