Assumed Business Names in Oregon: What a DBA Does and What It Does Not

If you run a business in Oregon under any name other than your own full name, or other than your LLC's registered name, Oregon law expects that name to be registered with the Secretary of State as an assumed business name before you use it. Most people call it a DBA, for "doing business as." The registration is cheap and fast, which leads a lot of owners to assume it does more than it does. It does one job, and it is worth being clear about what that job is and what it is not.

What an assumed business name is

Oregon's statute defines a "real and true name" differently depending on who you are. For an individual, it is your surname together with your given names or initials. For an LLC or corporation, it is the name on file with the Secretary of State in your articles. Any name you use to identify your business that does not conspicuously disclose the real and true name of every person running it is an assumed business name.

That definition reaches further than most owners expect. "Jared Hight" is a real and true name. "Hight Consulting" is not, because it does not include a given name or initial. "J. Hight & Associates" is not either, even though it includes an initial, because the statute specifically treats words like "Company," "& Associates," or "& Sons" as suggesting additional owners who are not named. If the name implies there is anyone behind the business beyond the people whose full names appear in it, it is an assumed business name.

The same rule applies to entities. My own firm is an example: the LLC on file with the Secretary of State is Evergreen Estate Solutions LLC, and Track Town Law is its registered assumed business name. An LLC does not get to use trade names freely just because it is an LLC; each one needs its own registration.

When registration is required

The statute says no person may carry on, conduct, or transact business under an assumed business name in a county where the business is located, has a physical facility, or has employees stationed, unless the name is registered and the registration is current. Registration is with the Secretary of State and is statewide in the sense that there is one filing, but the application lists the counties where you will operate, and that is what determines where the registration covers you.

The filing itself asks for the assumed name, the real and true name and street address of each person who will do business under it, the principal place of business, the counties, a designated representative, and the primary business activity. The current filing fee is fifty dollars. The registration lasts two years and has to be renewed, with its own fee, within the window before the two-year anniversary. The Secretary of State sends a renewal notice, and letting the registration lapse is grounds for the state to cancel it administratively. An expired name can be reactivated.

Registering a service mark as an assumed business name is also required if you use the mark to identify your business without conspicuously disclosing your real name alongside it. That catches the owner who thinks of a logo or tagline as branding rather than as a business name.

What happens if you do not register

Two consequences, and the first one is the one that bites.

A person doing business under an unregistered assumed name lacks standing in Oregon courts to maintain a cause of action for the benefit of that business. In plain terms, if a customer does not pay and you sue under your trade name without having registered it, the court will not hear your case until you fix the registration. The statute lets you cure the defect by registering, but it does not pause the statute of limitations while you do. An owner who discovers the problem late in the limitations period can lose the claim altogether.

The second consequence runs the other direction. Someone who sues you over business conducted under an unregistered assumed name can recover five hundred dollars, or their actual cost of figuring out your real name, whichever is greater, on top of whatever else they win. The registration exists so the public can find out who stands behind a trade name, and the law charges you for making that harder.

There is a practical consequence too, which is not in the statute but shows up at the bank. Banks generally will not open an account in a trade name, or accept checks made out to it, without seeing the assumed business name registration. A sole proprietor operating under a trade name who has not registered it will usually be told to come back with the filing.

What registration does not do

This is the part that costs people money when they get it wrong.

Registration does not create a legal entity. A sole proprietor who registers a trade name is still a sole proprietor. There is no separation between the business's debts and the owner's personal assets, because there is no business apart from the owner. The assumed business name is a label on a sole proprietorship, not a replacement for an LLC. If the reason you are thinking about a DBA is that you want protection from business liabilities, you are thinking about the wrong filing; what you want is covered in the post on when to form an LLC, and the post on what an LLC does and does not protect you from explains the limits of the protection once you have it.

Registration does not give you exclusive rights to the name. The Secretary of State will refuse to register a name that is not distinguishable on its records from an existing registered name, so there is a weak first-come effect. But the statute says the state's review is ministerial, meaning the clerk checks the form, not whether you are entitled to the name. A registered assumed business name is not a trademark. It does not stop a business in another state, or a business in Oregon with a prior common-law claim, from using the same name, and it will not win you a trademark dispute. The statute also says in so many words that nothing in the assumed business name chapter limits the law of unfair competition, which means that if your registered name creates a likelihood of confusion with someone else's established mark, the registration is no defense. Oregon also separately prohibits registering or using an assumed name with the intent to create confusion with another person, and provides for cancelling the registration after a court judgment. If the name matters to the value of the business, trademark protection is a separate question, and the post on intellectual property basics for Oregon businesses covers where that starts.

Registration is not a license to operate. It does not substitute for the local business licenses, state registrations, or professional licenses your activity requires.

And registration is not a substitute for a second entity. Owners who run several lines of business under one LLC sometimes register an assumed name for each line and assume that creates some separation between them. It does not. The LLC is one entity with one set of assets and one set of liabilities no matter how many trade names it has registered. Whether that is fine or a problem depends on what the lines do, which is the question the post on running more than one business under a single LLC works through.

Where counsel actually earns the fee

The filing itself is not where you need a lawyer. It is a short form and a small fee, and the Secretary of State's office processes it in a few days.

The decisions around the filing are a different matter. Whether the name you want is clear to use is not something the Secretary of State's search tells you; it tells you whether the name is distinguishable from other registrations, not whether someone has a trademark claim that will surface the first time you have revenue worth suing over. Whether a DBA is the right vehicle at all, as opposed to forming an LLC and letting the LLC carry the trade name, depends on the liability exposure of what you are doing and on what you plan the business to become. Whether a second line of business belongs under an existing LLC or in a new one is a structural question with tax and liability consequences on both sides. And whether the name you have been using for the last three years without registering it has already cost you something, or will, depends on what contracts and disputes are sitting in the file.

Those are the questions worth paying for. The form is not.

Bottom Line

An Oregon assumed business name is a public record of who stands behind a trade name. The law requires it before you do business under that name in a county, the consequences of skipping it fall hardest when you need to sue someone, and the filing is cheap and quick. What it does not do is protect your personal assets, give you ownership of the name, or separate one business from another. Those are entity and trademark questions, and the assumed business name registration answers none of them.

If you are choosing a name, deciding whether you need an LLC behind it, or sorting out a trade name that has been in use for years without a filing, that is a conversation worth having before the next contract goes out.
