What Is a Fictitious Name in Delaware?

A fictitious name is a name a business uses that differs from its legal name. It is also commonly referred to as a trade name or DBA, meaning "doing business as." Delaware uses a statewide trade name registration system administered by the Division of Revenue.

For example, Green Valley Enterprises LLC may operate a store under another name. Registering that name does not create another LLC or corporation. It records the additional name associated with the existing business without creating a separate legal entity

What Are the Requirements for Delaware Fictitious Name Filing?

Since February 2, 2026, the Delaware Division of Revenue has handled new trade name registrations statewide through Delaware One Stop. Key requirements include:

  • Business License: The trade name must be linked to an active Delaware business license. Businesses that do not operate in Delaware but need to register a Delaware trade name must obtain a Trade Name-Only License.
  • Business Details: Applicants provide information such as the legal name, address, proposed trade name, formation date, ownership details, and business activity.
  • Registration Fee: Delaware charges a one-time $25 fee for each new trade name.
  • Online Filing: New registrations are completed online, and notarization is no longer required.

Preparing these details in advance can help make the registration process more straightforward.

How Do You File a Fictitious Name in Delaware?

The Delaware trade name registration process now follows a statewide system through Delaware One Stop rather than the former county-level process. Business owners can complete the registration by following these steps:

  1. Check the Trade Name: Search Delaware's trade name registry and One Stop system for existing registrations. Review the available information before selecting a trade name, as registration does not provide exclusive rights to the name.
  2. Confirm the Business License: Make sure the business has an active Delaware business license or, where applicable, a Trade Name-Only License.
  3. Gather Business Information: Prepare the legal and trade names, address, formation date, ownership information, and business activity details.
  4. Submit the Registration: Complete the application through Delaware One Stop. Services such as MyCorporation can also help businesses navigate DBA-related paperwork and filing requirements.
  5. Pay the Filing Fee: Pay the one-time $25 registration fee for each trade name.

Following the current statewide process is important because older sources may still describe the former county-level filing process.

What Happens After Filing a Delaware Fictitious Name?

A Delaware trade name does not expire and does not require renewal. However, the associated business license must remain active. A Trade Name-Only License, when applicable, requires annual renewal.

Businesses can update ownership details, key personnel, or addresses through Delaware One Stop. They can also terminate a trade name through the portal when they stop using it, without a termination fee.

What Mistakes Should You Avoid When Filing?

Business owners can avoid delays and confusion by watching for these common mistakes:

  • Following Outdated Instructions: Since February 2, 2026, new trade name registrations have been handled through Delaware One Stop rather than individual county Prothonotary Offices.
  • Confusing a DBA With an Entity: Registering a trade name does not create a new LLC or corporation.
  • Providing Incorrect Details: Business, address, and ownership information should be accurate.
  • Ignoring License Requirements: The Delaware business license or Trade Name-Only License associated with the trade name must remain active.

Checking these details before submission can help prevent avoidable filing issues.

Conclusion

A Delaware fictitious name allows a business to operate under a name different from its legal name without creating a separate entity. Business owners should confirm licensing requirements, prepare accurate business details, and follow Delaware's current statewide registration process. Because filing procedures can change, it is important to check current guidance from the Delaware Division of Revenue before applying. Proper preparation can simplify registration and help business owners keep their trade name and related business information accurate over time.
