Foreign Corporations in Delaware: Qualification Certificate and Registered Agent

Delaware uses the word foreign for any corporation organized under the law of a jurisdiction other than Delaware, whether that is another state or another country. A foreign corporation has to qualify before it does business in the state. This page is about that situation, a company with its home elsewhere that is setting up operations in Delaware, and not about incorporating here.

The act is called qualification, and the statute behind it is section 371 of the General Corporation Law. The Division of Corporations in Dover files a qualification certificate, then issues its own certificate of qualification to the registered agent. That second document is prima facie evidence that the corporation may do business in Delaware.

Section 371 bars a foreign corporation from doing any business in Delaware through branch offices, agents or representatives located here until it has paid the fee and filed the papers. The statute never defines doing business. What it provides, in section 373, is a short list of situations in which a foreign corporation does not have to qualify:

• A mail-order or similar business that only receives orders by mail or advertising responses, accepts them outside Delaware and ships goods in
• Salespeople who solicit orders with samples, where every order is approved outside Delaware, goods ship from outside, and samples are for display only
• A sale made by contract outside Delaware of machinery, plants or equipment, when the seller's only local work is supervising the installation
• Business operations that are wholly interstate in character
• Being an insurance company doing business in Delaware
• Borrowing or lending, or acquiring debt, mortgages and liens on real or personal property
• Pursuing unpaid debts, including enforcing a lien or mortgage against collateral

Read the list for what it leaves out. It says nothing about meetings, bank accounts, defending a lawsuit, using independent contractors or owning property, so you cannot assume those are safe. A separate section, 382, treats carrying on any business activity in Delaware, including soliciting orders here, as transacting business for the purpose of serving a lawsuit on the Secretary of State. When your contacts with Delaware are a close call, ask a Delaware lawyer before you decide to skip the filing.

The filing is the Qualification Certificate of a Foreign Corporation. The Division publishes it as a template without a form number, and its cover letter says the filing is made under section 371. The state's fee is $245 on the Division's August 2026 fee schedule. A certified copy of the filed certificate costs $50 more. Same-day handling is $100 extra and 24-hour handling is $50 extra, and the schedule lists one-hour and two-hour priority service at higher rates.

Filing is done by mail to 401 Federal Street, Suite 4, Dover, or electronically by picking the Document Filing and Certificate Request option in the Division's eCorp Business Services area. That option only receives documents. It does not work out the fee, and the charge is applied once the order is processed. Checks go to the Delaware Secretary of State.

What the certificate says

• The corporation's name, with a Delaware-only name added if the true name cannot be used here
• The jurisdiction where it was incorporated
• The Delaware registered office and the registered agent's name
• Total assets and total liabilities as of a date within six months before filing, entering 0 if there are none
• The specific business it will do in Delaware, because a general purpose statement is not enough
• A statement that the business is the same as what the home jurisdiction authorizes

An authorized officer signs. The balance-sheet figures are a statutory requirement in section 371(b)(2), not a Division preference, so have them ready before you start.

Delaware requires one. Under section 371(b)(1) the document must evidence the corporation's existence and come from an official of the home jurisdiction who is authorized to certify it. Its date has to fall within the six months leading up to your Delaware filing, and the Division's instructions repeat that limit. A foreign-language original needs a translation sworn by the translator.

The owner orders it from the home filing office, which sets the price and the turnaround. Time the order so that the document is still inside the six-month window when your papers reach Dover, and order a fresh one if the filing slips. Some jurisdictions call the document a certificate of good standing, so check that what your home office issues evidences the corporation's existence.

Under section 371(c) the Secretary of State will not issue the certificate unless your name stands apart on the Division's records from reserved names and from other corporations, partnerships, limited partnerships, LLCs and statutory trusts. If your name collides, the corporation can qualify under an assumed name used only in Delaware, or file the written consent of the holder of the conflicting name. Check availability with the Division before you file.

Who can be the agent

Section 371(b)(2) lets the agent be an individual resident of Delaware, a Delaware corporation, partnership, LLC or statutory trust, or a foreign corporation, partnership, LLC or statutory trust other than the applicant. The statute even lists the corporation itself. Whoever serves, the registered office must be in Delaware, and section 132 requires an entity agent to maintain a business office that is generally open at sufficiently frequent times to accept service of process, or an individual agent to be generally present at a set location. An agent may not do the job solely through a virtual office, a mail forwarding service, or both.

Your contact person and changes

Section 132(d) also requires a communications contact. The corporation tells its agent which natural person, such as an officer, director, employee or designated agent, receives messages passed along by the agent, and supplies that person's name, business address and phone number. A change of agent is a short certificate with a $50 fee. If an agent dies, leaves Delaware or resigns, the corporation has 10 days to name a replacement.

The recurring obligation is an annual report, due on June 30 beginning the year after qualification took effect. The fee is $250. The report gives the registered office, the agent, the principal place of business and the names and addresses of all directors, and an officer or director who knowingly states something false commits perjury. The late penalty is spelled out differently in two official places: the statute sets two hundred dollars, while the Division's instructions page says $250. Confirm the figure on the Division's page when you file. If the report goes unfiled across a two-year period, section 375 directs the Secretary of State to terminate the corporation's right to do business here.

Delaware's franchise tax chapter applies to corporations incorporated in Delaware, so the foreign corporation's yearly filing is the report. Taxes owed to other agencies are separate.

Changes, withdrawal and reinstatement

• Name or business change. File a certificate within 30 days after a change of name or of the Delaware business takes effect. A name-change amendment is $100.
• Merger. If the foreign corporation survives a merger, it files a certificate from the home state within 30 days. The Division lists the merger filing at $50.
• Withdrawal. The corporation files a certificate of withdrawal, which gives an address where the Secretary of State will forward any process. The fee is $175, and all annual reports that are due must be filed first.
• Reinstatement. A corporation whose qualification was forfeited can be reinstated by certificate for $125, together with the missing annual reports and fees.

The consequences come from sections 378 to 384.

• Fines. A foreign corporation doing business of any kind without complying is fined for each offense, within a statutory range that tops out at $500. An agent who does business for it before it complies faces its own fine, up to $500 per offense.
• No lawsuits. Until it is authorized and has paid every fee, penalty and franchise tax for the years it operated without authority, the corporation cannot maintain an action or special proceeding in Delaware.
• Contracts survive. The missing authority does not impair any contract or act, the other party can still sue on the contract, and the corporation may defend a case.
• Injunction. The Court of Chancery can enjoin the corporation from transacting business here, with the Attorney General bringing the case.
• Service on the state. A corporation that transacts business without qualifying is deemed by Delaware law to have appointed the Secretary of State for lawsuits arising here, and a plaintiff who serves the state pays a $100 fee.

If your corporation was formed elsewhere, Mainstay's foreign qualification service takes care of the Delaware registration. It prepares the qualification certificate and files it with the Division of Corporations. Your Delaware registered agent comes with it at no extra charge for year one, and after that the agent costs $149 annually. Delaware's filing fee is $245. You supply the company details, the asset and liability figures and the specific business to be done here. Getting the certificate of existence is your job, since Mainstay does not order documents from the home jurisdiction.

The annual report, any taxes and the June 30 date stay with you or your accountant. Mainstay is not a law firm, so any judgment about whether your activities add up to doing business in Delaware belongs with you and your attorney.
