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 may be required before you obtain a business license, so please check with the county and cities where your business will be operated in Clark County. 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.
