Fictitious Firm Name

Fictitious Firm Name

It is required by law in the state of Nevada that every person doing business in this state under an assumed or fictitious name, that does not show the real name of each person who owns an interest in the business, must file a fictitious firm name (FFN) certificate with the County Clerk of each county in which the business is being conducted.

An FFN is required to be filed before a business license can be issued. A person doing business in this state without complying with the legal requirements or having falsely filed an FFN certificate of termination is guilty of a misdemeanor.

PLEASE NOTE: The filing of a certificate for an assumed or fictitious name does not give exclusive rights to the use of that name.

To file for a new fictitious firm name (dba) or renew an existing name, complete the form online and print it out. We do not offer online filing of these documents at this time. You must submit an original form with signatures which we will keep for our records. Please note:

  • Fictitious Firm Name forms must be notarized OR signed in person in front of a deputy clerk. If signing in person, you must show a valid government issued photo ID. All signatures must be verified.
  • You can use an online electronic notary service for your form so long as the physical documents and payment are sent to our office. The form must clearly contain the notary's seal, name and other required information where applicable on the form. If the electronic notary is not commissioned in Nevada, additional information must be provided on how we can verify the notarization; examples include a copy of the transaction log, link to the official audio/video session, a document providing instructions for online verification with the vendor, etc.
  • If a non-Nevada jurat is used for the notarization page in place of the section on our form, it must specify the type of document being notarized or it will be rejected.
