A Texas single-member LLC operating agreement is a legal document that is typically implemented after the formation of a limited liability company with a sole owner. It establishes the rights and responsibilities of the owner in relation to the company, protecting any personal assets from potential bankruptcy or legal claims faced by the business. This document also allows the owner to establish basic operations and policies to be implemented internally within the company. While an operating agreement is not required in Texas, financial institutions, insurance companies, and investors may require the business to provide one in order to prove credibility. Because the document only has one signatory, it is highly recommended that the owner sign and date the document in the presence of a notary public.
