New York State law requires all LLCs to develop a company agreement to define the company`s rules and regulations. In addition, the form makes it possible to document the rights of each member and the initial investments in the company. Each member must check the document before signing it and keeping it as a personal reference. If a company has a single member, it uses a company agreement with a single member, as provided for in New York law. Enterprise agreements with a single member offer several forms of protection, including protection of legal decisions and creditors. The New York LLC Corporate Agreement is a document legally required in New York State, whether it is an individual member or an agreement with multiple members.
