Delaware DBA / Fictitious Name / Trade Name Registrations

Registration requirements for Delaware business entities

Business entities that plan to use a name other than their legal business name may need to register an assumed name. Assumed name registration can take place at the state, local, or state and local levels of government. State specific registration information is available below.

Delaware Fictitious Name Registrations

Delaware Trade Name Registration

Is registration mandatory?

A corporation or limited liability company transacting business in Delaware under a trade name or title that does not disclose the legal name of the corporation or limited liability company may, but is not required to, register the trade name with the Division of Revenue. Individuals, associations, and other entities using any trade name or title which does not disclose their legal name must register the trade name with the Division of Revenue.

County Level Filing:

Trade names are only filed at the state level in Delaware.

Does registration prevent others from using the name I choose?

Delaware Trade names do not confer any legal rights and only ensure the appropriate parties can be reached in the event contact is necessary for legal or other reasons.

Agency:Delaware Department of Finance - Division of Revenue
Law:

Notes:

Effective February 2, 2026, the Delaware Division of Revenue will assume exclusive authority over all trade name (DBA) registrations statewide. This change replaces the current county-level system previously administered by the Courts of New Castle, Kent, and Sussex Counties.
