Assumed-Name (DBA) Registration Requirements in New Jersey

Requirements one by one

Who must register — and which system applies

New Jersey runs two parallel systems, and which one you use depends on what kind of business you are.

• Sole proprietors and general partnerships use the old Trade Name Act. "No person shall conduct or transact business under any assumed name ... other than the real name or names of the individual or individuals" without filing a certificate (§ 56:1-2). A related section catches a partnership that tacks on "and company" or "& Co." to its name (§ 56:1-1).
• Corporations, LLCs, and LPs use the "alternate name" system. A corporation may not "transact any business in this State using a name other than its actual name" unless it "has first registered the alternate name" (§ 14A:2-2.1(1)); LLCs and LPs register the same way through their own statutes.

Two groups file nothing: an entity operating under its exact formation name, and a partnership whose name "shall include the true or real names of all members" (§ 56:1-5). Limited liability partnerships have no alternate-name provision at all, so an LLP simply operates under its registered name.

Where you file

The office also splits by type. An individual or partnership files the trade-name certificate "in the office of the clerk of the county or counties in which such person conducts or transacts ... business," and also sends "a duplicate thereof for filing in the office of the Secretary of State" (§ 56:1-2). Note "or counties": if you operate in more than one county, you file in each. A corporation, LLC, or LP instead files a single certificate of alternate name with the state Division of Revenue & Enterprise Services (§ 14A:2-2.1(2)); there is no county filing for an entity.

When to file

Neither system sets a hard deadline, but the alternate-name track has a built-in penalty for waiting: a corporation that uses an alternate name before registering must, when it finally files, pay the ordinary fee "plus an additional filing fee equal to the full amount of the regular filing fee multiplied by the number of years it has been using such alternate name" — $50 for each year of prior use, with any part of a year counted as a full year (§ 14A:2-2.1(5)). The practical rule for entities is: register the alternate name before you use it.

No newspaper publication

New Jersey requires no newspaper publication for either route. There is no advertisement step and no proof-of-publication affidavit — a point of contrast with states like California and New York that build publication into the process.

The fee

For an individual or partnership, the statute fixes the fee: the county clerk and the Secretary of State "shall each receive a fee of $5.00" for indexing and filing, so the certificate costs $5 at the county plus $5 for the state duplicate (§ 56:1-3). For an entity, the Division of Revenue charges $50 to register an alternate name; renewal is $25 for corporations and LPs and $50 for LLCs.

How long it lasts

An individual or partnership trade-name certificate has no statutory expiration and no renewal cycle — it stays on file. An entity's alternate name is different: the registration "shall be effective for five years from the date of filing" and "may be renewed successively for additional five-year periods" by filing a renewal "within three months prior to, but not later than, the date of expiration" (§ 14A:2-2.1(3)). The state sends a reminder before the five years run, but the duty to renew is the registrant's.

Registration is not name protection

Neither filing locks up the name. An alternate-name registration does not "grant to the registrant ... any right in the name as against any prior or subsequent user of the name," and does not stop a court from enjoining a confusing name under unfair-competition law (§ 14A:2-2.1(4)). A county trade name is likewise just a public record of who is behind the name. Exclusive rights come from trademark law.

What happens if you skip it

The consequence differs by system. For an individual or partnership, operating under an unregistered trade name "shall be guilty of a misdemeanor" (§ 56:1-4). For an entity, the penalty is a curable suit-bar: the corporation may not "maintain any action or proceeding in any court of this State arising out of a contract or act in which it used such alternate name until it has filed" (§ 14A:2-2.1(6)) — but nonregistration does not void the underlying contracts and does not stop the company from defending a suit. A false statement about when the name was first used carries a separate $200–$500 forfeiture (§ 14A:2-2.1(7)).

What trips people up

• The county-vs-state split turns on your entity type, not your county. A freelancer or general partnership files at the county clerk (§ 56:1-2); an LLC or corporation files an alternate name with the state (§ 14A:2-2.1). Filing in the wrong system leaves you unregistered in the one that applies to you.
• Multi-county operators file more than once. The trade-name statute says "county or counties" (§ 56:1-2). A sole proprietor working across county lines files a certificate in each county of operation, each with its own $5 county fee and $5 state duplicate.
• Use an entity alternate name before registering and you pay for the wait. The $50-per-year back-fee for prior use (§ 14A:2-2.1(5)) can dwarf the ordinary $50 filing fee if the name has been in use for years. Register first.
• The entity alternate name expires; the county trade name does not. An LLC that forgets its five-year renewal loses its registration (§ 14A:2-2.1(3)), while an individual's county certificate simply stays on file. Track the five-year date if you are an entity.

Common questions

I'm a freelancer using a business name — county or state? County. As an individual, you file a trade-name certificate with the clerk of the county where you work (§ 56:1-2), not with the state alternate-name system, which is for corporations, LLCs, and LPs.

My LLC wants to run a second brand — what do I file? An alternate name with the Division of Revenue for $50, effective five years and renewable (§ 14A:2-2.1(3)). Your LLC keeps its formation name; the alternate name is an add-on for that brand.

Do I have to advertise the name in a newspaper? No. New Jersey has no publication requirement for either a county trade name or a state alternate name.

What actually happens if I never register? For an individual or partnership, operating under an unregistered name is a misdemeanor (§ 56:1-4). For an entity, you can keep operating and your contracts stay valid, but you cannot sue on that business in a New Jersey court until you register the alternate name (§ 14A:2-2.1(6)).
