(a) If a document delivered to the office of the Secretary of State for filing satisfies the requirements of section 21-1903, the Secretary of State shall file it.
(b) The Secretary of State files a document by stamping or otherwise endorsing "Filed," together with the Secretary of State's name and official title and the date and the time of receipt, on both the original and the document copy. After filing a document, except as provided in sections 21-1936 and 21-19,154, the Secretary of State shall deliver the document copy, with the acknowledgment of receipt of the filing fee, if a fee is required, to the domestic or foreign corporation or its representative.

(1) Affect the validity or invalidity of the document in whole or in part;
(2) Relate to the correctness or incorrectness of information contained in the document; or
(3) Create a presumption that the document is valid or invalid or that information contained in the document is correct or incorrect.
