A Florida single-member LLC operating agreement is used to formally establish the internal structure of a limited liability company owned by one person. Although Florida state law does not require companies to have an operating agreement, it allows the owner to determine their own rules and provisions for the company, rather than being subject to state laws governing LLCs. In addition, having an operating agreement provides another layer of protection for the owner’s personal liabilities and assets by establishing the company as a legally separate entity. The document, once completed, should be electronically signed or notarized in order to timestamp the date and prove its authenticity.
