Are you a Delaware business owner who wants to be able to operate your company under an assumed name? If so, consider acquiring a doing business as (DBA) name.
How do you obtain a DBA name for your Delaware company, and how are you allowed to use your new name? In this guide, we’ll walk through every detail of the DBA acquisition process in this state.

Guru Tip: It’s important to understand that a DBA does not offer limited liability protection as the LLC does. The LLC is the most popular entity for small businesses and is easy to set up – by doing it yourself or hiring an LLC website.
How Do I File a Delaware DBA?
DBAs or “Trade Names” are registered in the county prothonotary's office in which your business operates. The standard fee to register a DBA is $25, and all the requirements and necessary forms can be found at this link. You must notarize the forms before filing them, and some counties may have special requirements, so it is best to check with your local office before filing the paperwork.
This ensures that your desired business name is available, and hasn’t already been claimed by another business in the state.
Get Your Business Domain
To fully embrace the business name, register your URL. With GoDaddy you’ll be able to quickly build a company website so that nobody else can use or take it.
What is a Delaware DBA?
For sole proprietorships and general partnerships, a DBA enables you to use a name other than the owner’s personal name. For limited liability companies and corporations, DBAs allow you to use multiple names to officially refer to your business activities.
There are many different reasons for Delaware companies to acquire ‘doing business as’ names.
- For sole proprietorships and partnerships, they can make your company sound more professional than simply using your own name. You can also open a bank account using your DBA, which can not only help you keep your business and personal assets separate, but customers often have a higher comfort level writing out a check to a business name rather than to an individual’s personal name.
- For corporations and LLCs, DBAs are frequently used to give the company the option of using different names for separate product lines. Another common usage of a DBA is to distinguish satellite businesses from your main company. Restaurant owners love to do this, as for example it can help a fine-dining establishment open a fast-casual spin-off restaurant without affecting customers’ perceptions of the original location. Whether you want to create this separation for marketing or accounting purposes (or both), a doing business as name gives companies options that they wouldn’t otherwise have.
In short, a DBA in Delaware allows businesses to communicate their image and express themselves in different ways without having to actually form a new business to do so.
How Long Does a Delaware DBA Last?
A DBA registered in Delaware is good for 5 years. If you want to continue using your DBA for more than 5 years, you will need to renew it prior to the expiration date.
Should I Hire a Professional DBA Filing Service?
If you’d rather not fill out the paperwork and register for a DBA yourself, there are plenty of reputable companies offering a service. For a fee, these services will assemble the relevant paperwork and submit it to your state, and all you have to do is supply them with some basic information.
Delaware’s DBA forms can be filled out online, but you will need to get the documents notarized prior to filing them with the county. Though it is a pretty simple process, it requires a few extra steps and cannot be filed at the state level. If you would like to save yourself the time and effort of finding a notary and visiting the prothonotary's office, most service providers (Ex: LegalZoom) charge a fair rate to handle DBA applications.
Conclusion
The doing business as name, or DBA for short, is one of the most simple business filings for Delaware entrepreneurs. The process to acquire one is quite straightforward, and you can begin using your new assumed name as soon as the state completes your filing.
