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.
UCC filing, notary, and apostille services
Beyond business entity filings, the Secretary of State also runs three other public-facing services:
- UCC search and filing — handled through Business Services alongside entity filings.
- Notary public commissions — a $25 application fee, plus a $5,000 surety bond.
- Apostilles and authentications — $5 per document.
