Arizona: Assumed-Name (DBA) Registration Requirements

Requirements one by one

The required county certificate and the optional state substitute

Arizona's two filing routes are easy to blur together. Section 44-1236(A) says
that a non-partnership business using a fictitious name that does not show the
owner "shall record with the county recorder of the county in which the place
of business is located" an acknowledged ownership certificate. But subsection
(E) exempts a business that has "filed a trade name certificate with the
secretary of state." The statewide filing is therefore optional as a filing
choice, but it can substitute for the county certificate when § 44-1236 applies.

The statewide route is broader. Section 44-1460(A) says any person,
partnership, corporation, firm, association, or other organization doing
business in Arizona "may register with the secretary of state" the name under
which it operates. That is why a partnership, although excluded from the county
mandate, can still choose statewide registration.

How long state registration lasts and what priority it carries

The statewide certificate lasts "for a term of five years from the date of
registration" (§ 44-1460.02(A)). A renewal application may be filed during the
six months before expiration, and each renewal adds another five-year term.

Arizona also gives the state filing more effect than ordinary public notice.
If the trade-name registration predates articles of incorporation or a
corporate-name reservation, it gives the registrant the "exclusive right to the
use of such name" (§ 44-1460.05(A)). That priority remains subject to trade-name
rights acquired earlier in good faith at common law (§ 44-1460.05(B)).

What happens if a required county certificate is missing

The consequence is a curable courthouse bar. A person or corporation operating
contrary to § 44-1236 "shall not maintain an action" on a contract or transaction
made in the fictitious name until the certificate is recorded (§ 44-1236(D)).
Recording cures the filing problem; the statute does not say the underlying
contract becomes void.

What trips people up

• "State registration is optional" does not always mean "no filing is
  needed." The Secretary of State correctly describes its own trade-name
  registration as optional. Section 44-1236 separately imposes a county
  certificate on covered non-partnership businesses and then treats the state
  certificate as an exemption from that county route.
• State name priority is not a clean trademark bill of health. Section
  44-1460.01 blocks an indistinguishable name from the state registry, and
  § 44-1460.05 creates a priority rule against later corporate filings. But the
  same statute preserves good-faith common-law rights, so an accepted filing
  does not eliminate an earlier user's claim.
• The two routes do not share one renewal rule. The state certificate has a
  five-year term. Section 44-1236 gives the county certificate no fixed
  expiration, but requires a new certificate when ownership changes (and when a
  corporation transfers the right to use the name).
• No Arizona statute in either route requires newspaper publication. A
  private party, bank, or local licensing process may ask for extra paperwork,
  but that is not the statewide DBA rule.

Common questions

Can I transfer a statewide trade-name registration? Yes. Section
44-1460.03 permits a written assignment recorded with the Secretary of State;
the assignee receives a new certificate for the remainder of the existing term.

Can the Secretary of State cancel the registration before five years? Yes.
Section 44-1460.07 requires cancellation on the registrant's request, for
nonrenewal, by court order, or when the registration was obtained with false or
misleading information.
