How to change your registered agent in Delaware, and what the process involves
Changing a registered agent in Delaware costs $50 at the state level and can be done without a gap in coverage, which makes it one of the cheapest filings a company will ever make. It is also one of the easier ones to get wrong, because three parties touch it (the old agent, the new agent, and the company) and each tends to assume that one of the others is watching the calendar.
This guide covers how to change your registered agent in Delaware for a corporation, what the form and the fee are, what the board has to do first, and what happens to your legal mail and franchise tax notice while the change goes through. It also covers the less common case where the agent resigns before you have replaced them, because that is where the real exposure sits, and the exposure there is the status of the company itself and not only its mail.
What a registered agent does and why Delaware cares which one is on record
Delaware requires every corporation to have and maintain a registered office and a registered agent in the state. The registered office is the agent's Delaware address, and it has to include the street, number, city, county, and postal code. The agent accepts service of process and other communications directed to the corporation and forwards them, and its duties also include forwarding the annual report information or an approved electronic notification.
The corporation has a matching obligation that is easy to overlook, because it must give the agent the name, business address, and business telephone number of a natural person who is authorized to receive communications for the company, and that person can be an officer, director, employee, or designated agent. An email address is useful in practice, but it does not replace those statutory details, and if the company fails to keep the contact current the agent is allowed to resign.
One piece of the correspondence matters more than the rest. According to the Division of Corporations' own FAQ, tax notices are printed in December of the year the tax is due and sent to the registered agent, and the registered agent is whichever one the corporation designated at formation or in a later filing. A domestic corporation's annual report and franchise tax are due on or before March 1 for the prior year, and the December notice is a reminder and a delivery mechanism, so the deadline applies whether or not the notice reaches you.
For a founder outside the United States the agent is also what makes incorporation possible without a physical presence in Delaware, which is covered in more detail in our guide to what a registered agent is.
Why companies change their registered agent
Most switches come from one of four situations: the renewal price went up, the agent stopped forwarding mail promptly, the company wants its registered agent bundled with its tax and compliance provider so that notices land in one place, or the agent has moved or closed its Delaware office. None of these requires a reason to be given to the state, because Delaware lets a corporation change its agent whenever its board decides to.
What Delaware law requires for a change
Section 133 of the Delaware General Corporation Law lets a corporation change the location of its registered office by resolution of its board of directors, and it says that by like resolution the registered agent may be changed to any other person or corporation, including the corporation itself. In practice the change is a board decision first and a state filing second, so approving a new subscription with a provider does not complete the process on its own.
The Division's certificate form follows that order. It states that the change was adopted by a resolution of the Board of Directors, and the Division's instructions say the certificate must be signed by an authorized officer under Section 103 of Title 8. A board can adopt the resolution by unanimous written consent instead of holding a meeting, unless the certificate of incorporation or the bylaws restrict that route, and the signed consent belongs with the minutes.
How to change your registered agent in Delaware, step by step
1. Arrange the new agent's appointment
Before anything is filed, confirm in writing that the new agent accepts the appointment, and verify its exact legal name and Delaware office address. Give it the statutory communications contact (a person's name, business address, and business telephone number), and add a monitored email address and a backup contact as practical safeguards.
Decide at this point who will prepare the certificate, who will submit it, and who will watch for the returned document. Keep the existing arrangement in place until the change is confirmed, because cancelling first and assuming someone else will finish the filing is how companies end up with a gap.
2. Have the board adopt the resolution
The resolution names the new agent and the registered office address with the detail Delaware requires, which is the street, number, city, county, and postal code. If the board acts by written consent, every director must consent in writing or by electronic transmission under Section 141(f), so a two-person board needs both signatures, and the signed consent is kept with the minutes.
3. Prepare the certificate
The Division publishes a Certificate of Change of Registered Agent/Office for Corporation under Section 133. It asks for the corporation's name exactly as it appears in the Division's records, the new registered office address, the name of the registered agent at that address, and a statement that the board adopted the change. An authorized officer signs it with their name printed or typed below the signature, and the name, street, county, ZIP code, and agent name should be checked against the appointment paperwork before it goes out.
4. Submit the document and the payment
The Division accepts the certificate through its Document Filing and Certificate Request Service, and it also accepts documents sent by mail or courier. The mail and courier memo is for check payments, so card and ACH payments go through the electronic submission service instead. For a mailed submission, checks are payable to the Delaware Secretary of State, the Division asks for a cover letter with your name, address, and phone or fax number, and the address is Delaware Division of Corporations, 401 Federal Street, Suite 4, Dover, DE 19901.
The online service has limits worth knowing about. Delaware describes it as a submission service and not as direct online filing, it does not calculate fees, and card or ACH charges are applied when the order is processed and not when the request is submitted. An upload confirmation is a useful record of what you sent, but it is not the filed certificate, so do not promise the board a completion date based on it.
The Division's fee schedule was revised on August 1, 2026, and its entry for a domestic corporate change of agent lists $50, which matches the current certificate instructions. Use the form linked from the Division's current change-of-agent page and not another amendment form, and ask any provider whether its quote includes preparing the certificate, paying the state fee, ordering a certified copy, or buying expedited service.
5. Confirm the change and finish the handoff
Delaware returns a stamped copy marked filed, which belongs in the minute book next to the board consent. Then check the Division's entity search for the new agent's name and address, keeping in mind that the search shows agent information and does not establish the company's current legal status.
Ask the former agent for any correspondence it received for you, confirm that the new agent's contact receives notifications, and only then deal with cancellation and renewal billing under the old service contract.
Changing the agent for a Delaware LLC
An LLC follows a similar sequence with a different form and different internal authority. The Division publishes a Certificate of Amendment Changing Only the Registered Office/Agent of Limited Liability Company under Sections 18-202 and 18-1105(a)(11) of the LLC Act, the filing fee is $50, and the form is signed by an authorized person under Section 18-204 instead of by a corporate officer.
Internal approval follows the LLC agreement and its allocation of authority between managers and members, so a corporate board consent is not a template for an LLC. A company formed elsewhere and registered in Delaware as a foreign entity uses the foreign-entity form, since the Division lists separate agent-change forms for foreign corporations and foreign LLCs.
What happens if your agent resigns before you replace them
This is the case that causes damage, and it involves two separate clocks. Under Section 136, a registered agent can resign without naming a successor, but its certificate has to state that written notice was given to the corporation at least 30 days before the certificate was filed, and the resignation does not take effect until 30 days after filing. The corporation is expected to appoint a replacement in the same way as an ordinary change under Section 133.
If a Delaware corporation does not designate a new agent before that second 30-day period ends, the statute says the Secretary of State shall declare its charter forfeited, and a foreign corporation loses its authority to do business in the state. For an LLC the equivalent consequence is cancellation of the certificate of formation. That is a much more serious outcome than missed mail, and it does not depend on whether anyone at the company considered the agent important.
Service of process is the separate and smaller point. Once a resignation is effective and no replacement has been designated, legal process against the corporation is served on the Secretary of State under Section 321, which provides for the Secretary to send notice and copies to the corporation's principal place of business shown in its records, or to its last registered office if none is shown. That mailing is not the same as having an active agent with a current company contact, and if the company's records are out of date the people responsible for it may not see the papers promptly.
A different procedure applies when an agent resigns and appoints a successor in the same filing. Section 135 covers that case, with the affected corporation ratifying and approving the change, and the no-successor timeline above should not be applied to it. If a resignation deadline has already passed, have Delaware counsel check both the agent record and the company's charter status before treating an ordinary change filing as the whole fix.
What to check after the change
Three things are worth doing in the week after the filing. First, confirm that the new agent holds your communications contact and that someone at the company actually monitors the email address attached to it.
Second, look at the franchise tax calendar. Delaware sends its notices to the agent on record in December, so if you switch between December and March, ask the outgoing agent for any notice it already received and check your filing obligation directly instead of assuming the new provider has everything. A Delaware LLC does not file the corporate annual report, and its annual tax is due June 1, so keep each entity's calendar separate from the agent-switch checklist.
Third, assign owners for the open items, because the old agent, the new agent, and the accountant will each assume another one has noticed. A short list covers it: who confirms the new agent appears in state records, who tests the contact notifications, who collects forwarded mail, who owns the March 1 filing, and who closes out the old subscription.
Common mistakes when changing a registered agent
Filing before the new agent has accepted is the first, and it leaves the company with an agent who has not agreed to receive its mail. Using a company name that does not match the Division's record exactly is the second, and it tends to get the certificate returned. Writing the agent's address without the county or postal code is the third, since the statute calls for a full street address for the registered office.
Forgetting the board resolution is the fourth, because the certificate states that the board adopted the change and the minute book should show that it did. Cancelling the old agent before the change is confirmed is the fifth, and it can leave the company without an agent for a stretch. Leaving the old plan running after the change is confirmed is the sixth, and it is the one that costs money instead of time.
How Inkle helps
Inkle's published process says that when a customer switches from another provider, Inkle files the Certificate of Change with the Delaware Secretary of State and saves the returned stamped copy under Documents, then Formation Docs. Inkle's Mailroom describes receiving and scanning mail, uploading it to a dashboard inbox, sending notifications, and offering physical forwarding or shredding options, and the features that apply depend on the service you buy.
Inkle also files Delaware franchise tax reports as a separate service, so ask who receives the notice, who prepares the report, and who approves payment, and do not assume that tax filing is included in a registered agent subscription. Even when a provider files the certificate for you, the board approval remains the company's responsibility.

Frequently asked questions
How do I change my registered agent in Delaware?
A Delaware corporation changes its registered agent by obtaining board approval and then filing a Certificate of Change of Registered Agent/Office with the Division of Corporations. The certificate gives the exact corporate name, the new registered office address, and the agent's name, and an authorized officer signs it. Keep the returned filed copy with the board approval.
How much does it cost to change a registered agent in Delaware?
The Division's current corporate form lists $50 for a one-page certificate, $9 for each additional page, and $50 for an optional certified copy. Expedited handling and provider services can add charges, so ask for an itemized quote, and confirm the figure on the Division's fee schedule, which was revised on August 1, 2026.
Do all directors need to approve a registered agent change?
If the board acts without a meeting under Section 141(f), all directors must consent in writing or by electronic transmission, subject to any restriction in the certificate of incorporation or bylaws. That unanimity rule describes the written consent route and should not be confused with the voting rules for a properly convened board meeting.
Can I change my registered agent online?
Delaware's Document Filing and Certificate Request Service accepts electronic submissions, but it is a submission service and not instant direct filing, and payment is charged when the order is processed. Track the returned filed document and not only the upload confirmation.
What happens if my registered agent resigns and I do not replace them?
A resignation without a successor becomes effective 30 days after the agent files its certificate, and the agent must have given the company written notice at least 30 days before filing. If a Delaware corporation does not designate a replacement within the statutory period, the Secretary of State must declare its charter forfeited, and an LLC's certificate of formation is subject to cancellation.
Does changing registered agents change my franchise tax deadline?
No, because a domestic corporation's annual report and franchise tax are due March 1 for the prior year, and a Delaware LLC does not file that annual report but owes its annual tax by June 1. Keep each entity's tax calendar separate from the agent-switch checklist.
