Oklahoma: Assumed-Name (DBA) Registration Requirements

Requirements one by one

File the trade-name report with the Secretary of State

Okla. Stat. tit. 18, § 1140 uses a direct trigger: a corporation or other
business entity doing Oklahoma business under any name other than its legal
name “shall file a report with the Secretary of State.” The definition reaches
corporations, LLCs, business and common-law trusts, partnerships, and any other
unincorporated business.

The report states the legal name, jurisdiction of organization, trade name, a
brief description of the business, and the address where business will be
carried on. An authorized representative signs. The statute gives no delayed
filing window measured from the first day of use.

Pay the $25 report fee

Okla. Stat. tit. 18, § 1142(A)(1) charges $25 for a report or other paper
required to be filed in the Secretary of State's office. The trade-name report
is such a required report. There is no county filing in the general trade-name
provisions and no newspaper-publication expense required by them.

Update or withdraw the report when specified

The statute sets no fixed expiration date or renewal cycle. Instead, § 1140.3
requires an amendment for a false or erroneous statement, a change in the kind
of business, or a changed or additional operating address. Section 1140.1
requires a withdrawal report when the entity ceases doing Oklahoma business
under the trade name.

The registry blocks indistinguishable filed names

Section 1140 requires the selected trade name to be distinguishable from the
listed entity, foreign-entity, trade, fictitious, and reserved names on the
Secretary of State's records. Section 1141 directs the office not to accept the
same or an indistinguishable name unless an exception such as written consent
or a court decree applies. That is registry-level name protection; the filing
does not replace a trademark analysis.

What trips people up

• There is no newspaper step. The governing provisions require a state
  report, not a two-week publication or publisher's affidavit.
• There is no five-year renewal. The statutory maintenance events are
  amendment, transfer, and withdrawal, not periodic renewal.
• The filing office is statewide. The general report goes to the Secretary
  of State, not a county court clerk.
• The statute states no special nonfiling remedy. The audited trade-name
  sequence supplies the duty and fee but no specific fine, jail term, civil
  penalty, or suit bar for failing to file.

Common questions

Does this cover a sole proprietorship? Section 1140 defines business entity
to include “any unincorporated business,” so an individual operating such a
business under a nonlegal trade name falls within the stated category.

Must the name be different from names already filed? Yes. The name must be
distinguishable on the Secretary of State's records, subject to the consent and
court-decree exceptions in § 1141.

What changes require an amendment? Correct a false or erroneous statement,
and amend for a change in the kind of business or a changed or additional
business address.
