Delaware: Foreign LLC Registration and Qualification Requirements
The short answer
A foreign LLC must register with the Delaware Secretary of State before doing business, but § 18-912 excludes listed activities including proceedings, internal affairs, bank accounts, independent-contractor sales, outside-accepted orders, debt and foreclosure activity, interstate commerce, and an isolated transaction outside a course of similar transactions; the statute sets no day limit and has no general property-ownership harbor. The authorized-person application requires the names, formation jurisdiction and date, existence affirmation, specific Delaware business, registered office and agent, Secretary-of-State service appointment, and Delaware start date, plus a home-jurisdiction existence certificate no more than six months old; the base fee is $200 and filing is by electronic document submission or mail. An unregistered LLC cannot maintain a Delaware action until it registers and pays all required fees and penalties, owes $200 for each year or part-year, and may be enjoined, while contracts, defense rights, and the member-manager shield remain protected; an enacted August 1, 2026 amendment doubles the Secretary-of-State service fee but leaves the base registration fee unchanged.

| Governing law and registration term | Delaware LLC Act, Subchapter IX; 'application for registration' filed with Secretary of State, returned as endorsed/certified registration (6 Del. C. §§ 18-901 to -912) |
|---|---|
| Trigger and required timing | Register before 'doing business' in Delaware. Read with § 18-912 safe harbors; outside them the Act does not define the outer boundary, so the result is fact-specific (§ 18-902) |
| Statutory safe harbors | Proceedings, internal affairs, bank accounts, securities offices, independent contractors, outside-accepted orders, specialized installation contract, debt/foreclosure and acquired collateral, isolated transaction with no day cap, interstate commerce, insurance-company activity, and member/manager status. No general property harbor (§ 18-912) |
| Application contents and signer | Foreign/Delaware name, jurisdiction and formation date, valid-existence affirmation, specific DE business/purpose, office and agent, SOS fallback, first/intended business date; executed by authorized person (§ 18-902; Division form) |
| Home-state evidence | Existence certificate issued by authorized home-jurisdiction officer no earlier than 6 months before filing; foreign-language certificate needs translator's sworn translation. Ordinary U.S. certificate needs no further authentication (§ 18-902(2)) |
| Name, agent, and local address | Name needs LLC identifier and domestic-name eligibility; written consent may cure non-distinguishability. Maintain DE office and agent with identical business-office address; eligible resident individual or listed domestic/authorized foreign entity, but not the foreign LLC itself (§ 18-904(a)–(b)) |
| Filing method, fee, and effective date | Electronic document-submission service or mail; $200 base. Secretary files, dates, and endorses accepted application and returns certified copy; no delayed-registration date appears in § 18-903 or official form. Optional expedite separately available (§§ 18-903, -1105) |
| Unregistered consequences and cure | Suit bar until registration plus all fees/penalties; $200 each year or part-year; contracts/acts and other party's suit valid, defense and member/manager shield preserved; Chancery injunction and SOS service. Service fee $50 through July 31, $100 Aug. 1, 2026 (§§ 18-907 to -911) |

Requirements one by one
Registration before doing business
6 Del. C. § 18-902 requires a foreign LLC to register with the Secretary of
State before doing business in Delaware. The filing is an application for
registration under Subchapter IX of the Delaware Limited Liability Company Act.
The positive boundary is not exhaustively defined. Section 18-912 supplies
specific exclusions, but an activity outside them is not automatically enough;
whether a mixed or novel pattern is “doing business” remains fact-specific.
Safe harbors, including the no-day isolated transaction
6 Del. C. § 18-912 excludes proceedings; internal affairs; bank accounts;
securities offices, trustees, and depositories; independent-contractor sales;
orders accepted outside Delaware; creating or acquiring debt; debt collection,
foreclosure, and holding property acquired through that enforcement; interstate
commerce; insurance-company activity; and status solely as a member or manager
of a domestic or foreign LLC.
One Delaware-specific exclusion covers an out-of-state machinery, plant, or
equipment sale whose Delaware installation needs technical engineers or skilled
employees not generally available, when the seller furnishes only those
installation services. The isolated-transaction exclusion has no fixed number
of days, but it does not cover a transaction in the course of similar
transactions. Delaware has no current general safe harbor for owning property;
the listed holding protection is tied to property acquired through debt
enforcement.
Application and home-state evidence
The application under 6 Del. C. § 18-902 states the exact foreign name and any
different Delaware registration name, formation jurisdiction and date, an
authorized person's affirmation that the LLC validly exists, the specific
Delaware business or purpose, registered office and agent, the Secretary-of-
State fallback appointment, and the date business first began or is expected to
begin in Delaware. The official form requires an authorized-person signature and
printed name; it has no notary block.
The accompanying certificate must be issued by an authorized officer of the
formation jurisdiction and dated no earlier than six months before filing.
Section 18-902(2) requires an oath-of-translator translation only when the
certificate is in a foreign language; it states no further authentication rule
for a certificate from another U.S. jurisdiction.
Name, registered office, and agent
6 Del. C. § 18-904(a) requires the registration name to contain “Limited
Liability Company,” “L.L.C.,” or “LLC” and to be eligible as a domestic LLC name.
A name that is not distinguishable may still be used with the other listed
entity's written consent filed with the Secretary.
Under 6 Del. C. § 18-904(b), the registered agent's business office must be
identical with the Delaware registered office. The agent may be a Delaware-
resident individual or a listed domestic or Delaware-authorized foreign entity.
Unlike Delaware's domestic-LLC agent rule, the foreign LLC being registered is
expressly excluded from serving as its own foreign registered agent.
Submission, $200 fee, and filing effect
The Division accepts documents through its electronic submission service or
by mail; the upload service is not direct online filing. The base fee is $200
under 6 Del. C. § 18-1105(a)(6), unchanged by the August 1 amendment. Optional
expedited processing is separately available, and the Division publishes the
current service schedule.
Under 6 Del. C. § 18-903, the Secretary dates, endorses, files, and indexes an
accepted application, then returns an endorsed certified copy. Neither that
section nor the official foreign-LLC form provides a delayed registration date.
Consequences, payment cure, and service transition
6 Del. C. § 18-907 bars the LLC from maintaining a Delaware action until it has
registered and paid all fees and penalties for every year or part-year of
unregistered business. The fixed fine is $200 for each year or part of a
year. Registration plus the required payments cures that statutory court bar.
The lapse does not invalidate a contract or act, block the other contracting
party's suit, prevent the LLC from defending, or remove the member-manager
liability shield solely because registration was missing. Under 6 Del. C.
§ 18-908, the Court of Chancery may enjoin the LLC or its agent from continuing
unregistered business.
6 Del. C. § 18-911(a) appoints the Secretary of State for civil process arising
from the unregistered Delaware business. Through July 31, 2026, subsection
(c) charges the serving plaintiff $50. Effective August 1, 2026, 85 Del.
Laws Chapter 273, §§ 22 and 45, and the future code version replace that amount
with the $100 fee in 6 Del. C. § 18-1105(a)(13). The base registration fee
remains $200.
What trips people up
- “Isolated” has no 30- or 90-day clock. The transaction must instead fall
outside a course of similar transactions. - Property ownership is not broadly protected. The express harbor covers
holding property acquired through debt enforcement, not ordinary investment
or operating property. - The Division asks for a specific purpose. Its form says a general purpose
statement is insufficient. - Electronic submission is not instant online filing. The Division reviews
and processes the uploaded document before the statutory filing occurs. - The August 1 change does not raise the registration fee. It changes service
and expedite provisions; the foreign application remains $200.
Common questions
How recent must the home-state certificate be?
It must be dated within the six months before the Delaware filing date.
Can the foreign LLC act as its own Delaware registered agent?
No. Section 18-904(b) excludes the foreign LLC itself from the eligible foreign-
entity agent category.
Can an unregistered LLC defend a Delaware lawsuit?
Yes. Section 18-907 preserves defense rights while conditioning the LLC's own
Delaware action on registration and payment.
Does one Delaware transaction require registration?
Not when it is isolated and outside a course of similar transactions. The
statute sets no completion deadline for that exclusion.
