Business Filing Fraud Prevention Act (2026)
The Mississippi Secretary of State's Office reports a sharp rise in fraudulent business entities being formed using someone else's personal address or identity without their knowledge. The 2026 Legislative Session passed the Mississippi Business Filing Fraud Prevention Act, giving the Secretary of State an administrative process for dissolving confirmed-fraudulent filings. Anyone whose personal information was used to form a business without permission can submit a notarized Declaration of Wrongful Business Filing Form to the office. The office has also separately warned businesses for years about third parties sending deceptive "Certificate of Existence" solicitation letters demanding payment — those letters are not sent or authorized by the Secretary of State.
