Each LLC is advised to establish a written corporate agreement and a foundation certificate, as well as to prepare for each corporation, articles and articles of incorporation. Note that the improper filing of these documents may result in delays. In order to support the proper structure and presentation of these governance documents, it is recommended to hire a lawyer. Company agreements and articles of association also differ due to legal form, obligation, state requirements, tax results, completeness and rigidity. Company agreements are often less formal and easier to change. .
