    4 Steps to Register Your Business Name in Delaware

    Registering your business name in Delaware is an essential step towards establishing your entrepreneurial presence in the First State. To guide you through the process, here are four simple steps to officially register your business name in Delaware:

    Step 1: Choose Your Business Structure in Delaware

    Selecting the most suitable business structure is a crucial aspect of commencing a business in Delaware. Your decision should take into account the nature of your business, the number of co-owners involved, and your future expansion plans. 

    Delaware offers several common business structures to choose from:

    Sole Proprietorship

    This is the simplest and most prevalent business structure in Delaware. As the sole proprietor, you bear personal responsibility for the business’s debts and liabilities, with no legal separation between you and the business. While you aren’t required to register your sole proprietorship with the state, local permits or licenses may be necessary.


    A partnership involves two or more individuals who share profits and losses. Delaware recognizes two types of partnerships:

    • General Partnership: A General Partnership is a business structure where two or more individuals share profits and losses. Each partner is personally and jointly liable for the business’s debts and legal obligations. This means that the personal assets of the partners may be at risk to cover the partnership’s debts or legal liabilities. It’s essential for partners to have a clear partnership agreement and consider the potential risks before entering into this type of business structure.
    • Limited Partnership (LP): Comprises general partners with unlimited personal liability who manage the business and limited partners who contribute capital but have limited liability. To establish an LP in Delaware, you must file a Certificate of Limited Partnership with the Delaware Secretary of State.

    Limited Liability Company (LLC)

    An LLC is a popular choice, offering liability protection akin to a corporation and the tax benefits and simplicity of a partnership. To create an LLC in Delaware, you need to file a Certificate of LLC Formation with the Delaware Secretary of State and create an Operating Agreement that outlines the company’s management and ownership structure.


    A corporation is a distinct legal entity from its shareholders and provides limited liability protection. Delaware recognizes two types of corporations:

    • C-corporations: Taxed separately from owners and shareholders
    • S-corporations: Allow businesses to avoid double taxation on profits

    To establish a corporation in Delaware, you must file a Certificate of Incorporation with the Delaware Secretary of State and create bylaws outlining the company’s management and ownership structure.

    Choosing the appropriate business structure in Delaware is pivotal, as it influences taxation, liability, and paperwork requirements. It’s prudent to seek advice from legal or business professionals to ensure you make an informed decision.

    Step 2: Select a Unique Business Name in Delaware

    Selecting a business name is far more than a mere formality; it plays a pivotal role in establishing your brand identity and attracting customers to your venture. In Delaware, there are three main options to consider when naming your business: registering a legal entity name, obtaining a trademark, or operating under a “Doing Business As” (DBA) name. 

    To navigate this process successfully, it’s crucial to grasp the specific requirements applicable in Delaware.

    When registering your business name in Delaware, it’s imperative to opt for a distinctive legal entity name. This name serves as an identifier for your company in the eyes of the state and should be unique to prevent any conflicts with existing businesses. It’s essential to follow Delaware’s guidelines regarding company suffixes like LLC, LP, or Corp and ensure that your chosen name aligns with the type of business you’re registering. 

    Before finalizing your decision, you can verify the name’s availability using the Delaware Secretary of State’s database.


    Securing a trademark for your business name or logo offers nationwide protection for your intellectual property. Conducting a comprehensive search in the USPTO database is a critical step to ensure that your preferred name or logo isn’t already registered by someone else. 

    Once your trademark is successfully registered, it grants you exclusive rights to use the name or logo for similar goods or services, effectively safeguarding your brand identity.

    Doing Business As (DBA)

    In Delaware, you have the option to operate your business under an official legal name while using a different name through a DBA. This flexibility allows you to create a unique brand identity that resonates with your customers. To establish a DBA name, you’ll need to file an Assumed Name Certificate (DBA) with the county clerk’s office where your business is based. Unlike legal entity names, DBAs are not required to be unique at the state level but are still subject to federal trademark laws.

    By thoughtfully considering these naming options and adhering to Delaware’s naming regulations, you can effectively register your business name and protect your brand in the dynamic and competitive market of Delaware. 

    Choosing a unique business name in Delaware will not only set the stage for your venture’s success but also make a lasting impression on your customers.

    Step 3: Check Business Name Availability in Delaware

    Before proceeding with business registration, it’s crucial to ensure that the desired name for your company is available and not already in use. To perform a comprehensive search for business name availability in Delaware, you should carry out three types of searches:

    The initial step involves conducting a federal trademark search to ascertain whether your chosen business name is already trademarked. Trademarks are registered at the national level, taking precedence over state-level registrations. Therefore, it’s essential to confirm that your preferred name isn’t already trademarked. Should it be trademarked, you will need to devise an alternative business name.

    To perform a federal trademark search, visit the U.S. Patent and Trademark Office (USPTO) website and utilize the TESS Search function.

    Once you have ensured that your business name isn’t trademarked, the next step is to verify its availability for use, specifically in Delaware. Utilize the Delaware Business Entity Search to look up registered business names in the state.

    During your search, check not only for the exact availability of your business name but also ensure that there are no other companies using significantly similar names.

    After confirming that your business name isn’t trademarked and is available for use in Delaware, it’s advisable to conduct a website domain search to verify the availability of the .com version of your business name. Even if you do not plan to create a website immediately, registering the .com domain for your business name is recommended.

    By registering the .com version of your business name with ZenBusiness, you ensure that no one else can begin to use that website name. Since it’s an affordable way to protect your business name from being used by someone else.

    By performing these three types of searches, you can ensure that your desired business name is unique and available for use in Delaware without any potential conflicts with existing trademarks or businesses.

    Step 4: Form Your Business With the State of Delaware

    After finalizing your business structure and name, the next crucial step is to officially register your business with the state of Delaware. This process ensures that your business is recognized and operates in compliance with state regulations.

    For a Delaware LLC, you’ll need to submit the “Certificate of Formation” to the Delaware Department of State. This document formalizes the creation of your LLC. You can submit the application either by mail or in person.

    If you’re establishing a Delaware corporation, the required document is the “Certificate of Incorporation,” which also needs to be filed with the Delaware Department of State.

    Protect Your Business Name With a Trademark

    Once you’ve verified the availability of your business name and secured it for use, you may consider applying for a trademark to protect your brand. The process usually costs between $225 to $400, excluding any attorney fees, and requires renewal every 10 years.

    While this option might be costly for start-ups or small businesses, obtaining a trademark provides nationwide protection under federal law. This legal safeguard allows you to defend your business name in case others attempt to use a similar name for their ventures. For most local businesses, trademark registration might not be necessary unless there are plans to expand nationally.

    How to File a Delaware Fictitious Name – DBA?

    To file a Delaware Fictitious Name (Doing Business As – DBA), follow these steps:

    1. Choose a Name: Select the fictitious name you want to use for your business
    2. Conduct a Name Search: Check the Delaware Division of Corporations’ website to ensure your chosen name is available and not already in use by another business
    3. Download the Form: Obtain the “Fictitious Name Registration” form from the Delaware Division of Corporations’ website or visit their office to get a physical copy
    4. Fill Out the Form: Complete the required information on the form, including your business name, address, and the fictitious name you want to register
    5. Notarize the Form: Have the form notarized, as notarization is required for the registration
    6. Submit the Form: Mail the completed and notarized form along with the appropriate filing fee (check the current fee on the Division of Corporations’ website) to the Delaware Division of Corporations
    7. Processing and Approval: The Division will process your application, and once approved, your fictitious name will be registered for your business

    Filing a DBA in Delaware is also known as filing for a “Trade Name.” The process allows you to operate your business under a name different from the legal name of your entity.

    How to Change the Name of a Delaware Business?

    If you need to change the name of your business in Delaware, you have two options:

    • Filing for a Trade Name (Doing Business As – DBA): This approach is the simplest way to operate your business under a different name without altering its legal name. Sole proprietorships and general partnerships primarily use this method. It’s also convenient for LLCs and corporations, as it allows them to use brand names without the required “LLC” or “Inc.” suffix present in their legal names.
    • Submitting an Amendment to the Legal Name: If you wish to officially change the legal name of your LLC or corporation, filing an amendment is the appropriate route. This process requires completing the “Certificate of Amendment” form specific to your business type.

    For either option, the relevant forms must be filled out and mailed to the Delaware Department of State, along with the appropriate filing fee, which is $194 for corporations and $200 for LLCs.

    Business Name Registration Laws in Delaware

    The business name registration laws in Delaware are as follows:

    • Choosing a Business Name: When starting a business in Delaware, you must choose a unique name that’s distinguishable from any other registered business in the state. This means that your business name cannot be too similar to any existing entity’s name to avoid confusion among customers.
    • Entity Types: Delaware allows different types of business entities, including corporations, Limited Liability Companies (LLCs), partnerships, and sole proprietorships. Each entity type may have specific requirements and restrictions regarding naming conventions.
    • Name Reservation: If you have a specific business name in mind but are not yet ready to register your business, you can reserve the name with the Delaware Division of Corporations. This reservation will provide you with exclusive rights to the name for a certain period (usually 120 days), giving you time to finalize your business setup.
    • Name Restrictions: Delaware state law prohibits the use of certain words in business names unless you obtain appropriate permissions or licenses. For example, words like “bank,” “university,” and “trust” may require specific regulatory approvals.
    • Trade Names: If you plan to operate your business under a name different from your legal business name, you will need to register a “Trade Name” or “Doing Business As” (DBA) name with the Delaware Division of Corporations.
    • Search for Existing Names: Before registering your business name, it’s essential to conduct a thorough search in the Delaware business name database to ensure that your desired name is available and not already in use by another entity.
    • Registering the Business: Once you have selected a unique business name, you will need to register your business with the Delaware Division of Corporations. The registration process may vary depending on the type of business entity you choose.

    Please note that business laws and regulations can change over time, so it’s crucial to verify the most up-to-date information with the Delaware Division of Corporations or seek legal advice to ensure compliance with current regulations.
