California Form COR-7 is the Certificate of Correction filed with the California Secretary of State to fix a typo, wrong date, missing signature, or other error inside a previously filed business entity document. Any officer, manager, partner, or authorized agent of the original filer can sign and submit it under California Corporations Code § 109.
The form matters because California rejects roughly 1 in 6 business filings on the first pass, according to the Secretary of State’s published rejection data on the bizfileOnline portal, and many of those rejections trigger COR-7 follow-ups. Filing it correctly the first time saves weeks of processing delay and avoids the lien, tax, or contract problems that flow from an inaccurate public record.
Here is what this guide will cover for the current Rev. 01/2025 version of the form, available on the Secretary of State’s business forms page:

What the Form Is and Who Must File It
Form COR-7 is the official Certificate of Correction used to amend a record already on file with the California Secretary of State. The form is authorized by Corporations Code § 109 for corporations and by Corporations Code § 17702.05 for limited liability companies. It corrects errors in Articles of Incorporation, Articles of Organization, Statements of Information, Certificates of Amendment, mergers, conversions, and dissolutions.
You must file COR-7 if the original document, as filed, contained an incorrect statement or was defectively executed, attested, sealed, verified, or acknowledged. The form does not create new rights, change the substance of the original action, or replace a Certificate of Amendment. It only fixes what was already there.
Typical filers include corporate secretaries, LLC managers, general partners, registered agents, and the attorneys who prepared the original document. Pro se founders also file COR-7 when they discover a typo months later. The signer must be a person authorized to sign the original document under the entity’s governing law, which the Secretary of State’s filing tips PDF explains in detail.
A common misconception is that COR-7 can be used to undo a filing. It cannot. If you want to cancel an action, you need a separate Certificate of Dissolution, Cancellation, or Withdrawal. COR-7 only corrects; it never reverses.
Before You Start: Documents and Information You Need
Before you open the COR-7 PDF, gather every piece of information below. Missing any one of these items is the single biggest reason filings get rejected, according to the California Business Search portal.
- Entity name exactly as filed. The Secretary of State matches against its database character-for-character, so even a missing comma will trigger rejection.
- 12-digit Secretary of State file number. Without this number the clerk cannot locate your record, and the filing will be returned unprocessed.
- A clean copy of the document being corrected. You need to quote the exact wrong language and write the exact replacement language.
- The original filing date. This anchors the correction in time and proves the error was on the original, not a later amendment.
- The specific provision, line, or sentence that is wrong. General statements like “the address is wrong” are rejected; you must point to the exact clause.
- The corrected text in full. California requires the new language to be quoted in full, not described.
- Authorized signer information. Full legal name, title, and current contact phone number.
- Filing fee payment method. A check, money order, or credit card authorization for the $30 standard fee, plus any expedited service fee.
- A return mailing address or email for the file-stamped copy.
- A self-addressed stamped envelope if you file by mail and want the stamped copy returned quickly.
If any item is missing when you start, stop and gather it first. The form has no save function, and partial filings are routinely rejected.
Where to Get the Form and How to Access It
The official COR-7 PDF lives on the Secretary of State business entity forms page under the heading “Corrections.” The current revision is Rev. 01/2025, printed in the bottom-left corner of page one. Always confirm the revision date before filing because the office rejects superseded versions.
You can also access the form through the bizfileOnline portal by logging in with a California government account, selecting your entity, and choosing “File a Correction.” The online version pre-fills your entity name and file number, which removes two of the most common rejection causes.
Third-party legal sites sometimes host older revisions. Avoid them. The Sacramento public counter at 1500 11th Street also stocks paper copies for walk-in filers. Print the PDF on plain white 8.5 x 11 paper, single-sided, and use black ink only. Colored ink, double-sided printing, and stapled pages will all cause rejection at the intake desk.
If you use assistive technology, the Secretary of State posts a tagged, screen-reader compatible version under the accessibility resources page. Filers with limited English proficiency may bring a translator, but the form itself must be completed in English under Government Code § 12181.
Step-by-Step: How to Fill Out Form COR-7 Line by Line
The form has one page with eight numbered items plus a signature block. Complete them in order. Skipping ahead is the second-most-common rejection cause, per the bizfileOnline help center.
Item 1: Entity Name
This box asks for the exact legal name of the entity as it appears in the Secretary of State’s records right now.
Type or print the name in all capital letters, including punctuation, “INC.”, “LLC”, or “L.P.” suffixes, and any commas. Maria Lopez, filing for her bakery, writes PAN DULCE BAKERY, INC. exactly as it appears on her Articles of Incorporation.
If the entity recently changed names, use the current name, not the old one. The correction will still apply to the old document because the file number anchors the filing.
The most common mistake here is dropping the comma before “INC.” or “LLC.” That single missing comma causes the database lookup to fail, and the filing is rejected within 48 hours of receipt. A widespread misconception is that “Inc” and “Inc.” are interchangeable; they are not. The system treats them as different strings.
Item 2: Secretary of State File Number
This is the unique identifier the state assigned when your entity was first registered. It is 7 to 12 digits long for corporations and begins with a number for LLCs.
Find it on your stamped Articles of Incorporation, on any prior Statement of Information, or by searching the California Business Search tool. Carlos Nguyen, correcting his consulting LLC, writes 202315610342 in this box.
If your entity was formed before 1980, the number may have a “C” prefix; include the prefix. For foreign entities qualified to do business in California, use the California-issued number, not the home-state number.
The most common mistake is using the EIN from the IRS instead of the Secretary of State file number. The two are completely different, and an EIN entry causes immediate rejection. The misconception driving this error is that “file number” means “tax ID.” It does not; in this box it means the state filing identifier.
Item 3: Date of Original Filing
Enter the date the original document was filed with the Secretary of State, not the date the error was discovered.
Use the format MM/DD/YYYY with slashes, not dashes or periods. Janet Brooks, correcting a 2023 merger filing, writes 03/14/2023. The date appears on the file-stamped copy in the top-right corner.
If you do not have the file-stamped copy, pull the date from the California Business Search results. The “Initial Filing Date” or “Last Document Filed” field shows the date you need.
A common mistake is writing today’s date instead of the original filing date. That converts the correction into a meaningless self-reference and the office returns the form. The misconception is that “date of filing” means the date you are filing the correction; it does not. It means the date of the document being corrected.
Item 4: Title of Document Being Corrected
State the exact title of the document you are correcting, as it was titled when filed.
Write the title in title case exactly as printed on the original. Aisha Williams, correcting her 2024 articles, writes Articles of Incorporation. Marcus Patel, fixing a merger, writes Agreement of Merger.
If the original document had a long subtitle, include the full subtitle. Statement of Information (Domestic Stock and Agricultural Cooperative Corporations) is a common full title that filers wrongly shorten.
The most common mistake is using a generic label like “Articles” or “SOI.” The clerk cannot match a generic label to a specific document, and the filing is rejected. The misconception is that the office can figure it out from the file number alone; it cannot, because many entities file dozens of documents and need the title for routing.
Item 5: The Incorrect Statement or Defect
Quote the exact wrong language, word for word, from the original document.
Use quotation marks and copy the language verbatim, including any typos in the original. Diego Ramirez, correcting his Articles of Organization, writes: The address of the initial agent for service of process is “1234 Main Stret, Los Angeles, CA 90015.” He keeps the typo in his quote because that is what was filed.
If the defect is an omission rather than a wrong word, describe what was missing. Example: Item 5 of the original Articles failed to include the name of the initial agent for service of process.
The biggest mistake here is paraphrasing instead of quoting. Paraphrased corrections are returned for revision because the office cannot confirm the exact text being changed. The misconception is that “describing” the error is enough; it is not. The office needs the specific words.
Item 6: The Corrected Statement
Write the corrected language exactly as it should now read on the public record.
Quote the full replacement clause, not just the changed word. Diego writes: The address of the initial agent for service of process is “1234 Main Street, Los Angeles, CA 90015.” He fixes “Stret” to “Street” but quotes the entire sentence so the office can swap it cleanly.
If you are correcting an omitted clause, write the full clause that should have been there. The name of the initial agent for service of process is John Smith, an individual residing in California.
A common mistake is showing only the changed word, like writing Street alone. The office cannot insert a single word into a complex document, so the filing is rejected. The misconception is that strikethrough or underline marks are enough; California requires full corrected text.
Item 7: Statement That the Defect Did Not Result From Fraud
This box requires you to certify, in writing, that the error was not the result of fraud and that the correction does not change the substance of the original action.
Check the pre-printed box and add the statutory language verbatim if the form version requires it: The undersigned declares that the corrections do not alter the substance of the original document and that the defect did not arise from fraud. Aisha checks the box and signs below.
If the correction would alter substance, you cannot use COR-7. You must file a Certificate of Amendment instead, governed by Corporations Code § 900 for stock corporations.
The most common mistake is checking the box when the correction actually changes voting rights, share counts, or member percentages. That misuse of COR-7 voids the correction and can expose the signer to liability under Penal Code § 115 for filing a false instrument. The misconception is that COR-7 is a cheap shortcut around the amendment process; it is not.
Item 8: Effective Date of the Correction
By default, the correction relates back to the date of the original filing. You may specify a different effective date only in narrow circumstances.
Leave this box blank for standard corrections. The relation-back rule is set by Corporations Code § 109(c). If you need a forward-dated effective date, write it in MM/DD/YYYY format, but never more than 90 days from filing.
Marcus, finalizing a merger, leaves this blank because he wants the correction to relate back to 03/14/2023. Janet, who needs the correction effective only after a regulatory approval, writes 07/01/2026.
The most common mistake is writing today’s date in this box. That accidentally cuts off the relation-back protection and exposes the entity to gap-period liability. The misconception is that listing today’s date is “safer”; in fact it removes a key legal benefit of COR-7.
Signature Block
Sign in blue or black ink. Print your name and title underneath, and add the date.
The signer must be the same person authorized to sign the original document, or a current officer, manager, or authorized representative. Aisha signs as Aisha Williams, Secretary, dates the form 05/20/2026, and prints her name in the line below.
Electronic signatures are accepted on bizfileOnline filings under the California Uniform Electronic Transactions Act. Paper filings require a wet-ink original; photocopied signatures are rejected.
The most common mistake is signing with a title the entity’s records do not show. If the database lists Aisha as “Director” but she signs as “Secretary,” the filing is rejected for unauthorized signature. The misconception is that any officer can sign; only those with current, on-file authority can.
Three Filled-Out Examples Using Real Scenarios
The three scenarios below show how three different filers complete COR-7 from start to finish. Each one walks through the same eight items plus the signature.
Scenario 1: Maria Lopez, Bakery Typo Correction

How to File the Completed Form
Form COR-7 may be filed through four channels. Each one has its own fee, processing time, and proof-of-filing rules under the Secretary of State’s service options page.
Online via bizfileOnline. Upload the signed PDF at the bizfileOnline portal. The base fee is $30, payable by Visa, MasterCard, American Express, or Discover. Standard processing runs 5 to 10 business days. The portal emails a file-stamped PDF as proof of filing. Save that email; it is your only receipt.
By mail. Send the signed original plus a check for $30 made payable to “Secretary of State” to: Secretary of State, Business Entities Filings, P.O. Box 944260, Sacramento, CA 94244-2600. Standard mail processing currently runs 4 to 6 weeks. Include a self-addressed stamped envelope to receive your file-stamped copy.
In person at Sacramento. Walk in to 1500 11th Street, 3rd Floor, Sacramento, CA 95814 between 8:00 a.m. and 5:00 p.m. Pay an additional $15 special handling fee at the counter. You receive the file-stamped copy the same day if you arrive before 4:00 p.m.
Expedited service. For 24-hour processing add $350, for same-day processing add $750, and for 4-hour processing add $500 under the preclearance and expedited services schedule. Expedited service is available only for in-person and drop-box filings, not for mail or standard online submissions.
Always keep a copy of the signed form, the payment confirmation, and the file-stamped return for at least seven years under Corporations Code § 1500.
What Happens After You File
Once the Secretary of State accepts your COR-7, the office stamps it with a filing date and indexes it under your entity’s file number on the California Business Search system. The corrected language replaces the defective language as of the original filing date, thanks to the relation-back rule.
You should receive a file-stamped copy within 5 to 10 business days for online filings, or 4 to 6 weeks for mailed filings. If you used expedited service, expect the stamped copy within the timeframe you paid for. Download and save the PDF; the office does not maintain free public copies indefinitely.
If the office finds a defect, it returns the filing with a rejection notice listing the reasons. The most common rejection reasons are signature problems, missing fees, and entity name mismatches. You have 90 days to refile without paying a new fee under the Secretary of State’s resubmission policy. After 90 days, the fee resets.
The corrected document is then visible to banks, the Franchise Tax Board, the California Department of Tax and Fee Administration, title companies, and contract counterparties. Notify your registered agent, your bank, and your insurance carrier so their internal records match the corrected public record.
Mistakes to Avoid When Filling Out the Form
- Using the EIN instead of the SOS file number. The clerk cannot match your filing to your entity, and it is rejected within 48 hours.
- Writing today’s date as the original filing date. This invalidates the correction and forces a complete refiling.
- Paraphrasing the incorrect statement instead of quoting it. The office cannot identify the language to replace and returns the form.
- Showing only the changed word in Item 6. Without the full corrected sentence, the office cannot insert the fix.
- Checking the fraud certification box when the correction changes substance. This exposes the signer to liability under Penal Code § 115 for filing a false instrument.
- Signing with a title not on file. The system flags unauthorized signatures and rejects the filing.
- Using colored ink or photocopied signatures. Paper filings require wet-ink black or blue signatures only.
- Mailing without a self-addressed stamped envelope. You may never receive the file-stamped copy back.
- Filing COR-7 to undo an action. Corrections cannot reverse filings; you need a Dissolution, Cancellation, or Withdrawal instead.
- Forgetting to update the registered agent. If the agent’s address was the error, the agent must accept service at the corrected address.
- Mismatched entity name punctuation. Missing commas before “INC.” or “LLC” cause database lookup failures.
- Sending a check made payable to the wrong office. Checks must read “Secretary of State,” not “State of California” or “California SOS.”
Each of these mistakes triggers either a rejection notice, a delay of weeks, or, in the fraud-certification case, possible criminal exposure. Slow down and double-check every box before you sign.
Dos and Don’ts
Dos
- Do verify the revision date in the bottom-left corner before printing, because outdated versions are auto-rejected.
- Do quote the incorrect and corrected language word for word, because the office matches text exactly.
- Do keep a digital and paper copy of the signed form, because file-stamped returns can be lost in transit.
- Do confirm the signer’s authority on the California Business Search before signing, because mismatched titles trigger rejection.
- Do file online when possible, because bizfileOnline pre-fills entity data and reduces typo risk.
- Do notify your registered agent, bank, and tax preparer after filing, because they rely on the corrected record.
Don’ts
- Don’t use COR-7 to change the substance of the original document, because that requires a Certificate of Amendment instead.
- Don’t write descriptions of the error; only direct quotes are accepted.
- Don’t forget the $30 fee, because unfunded filings are returned unprocessed.
- Don’t staple, double-side, or color-print paper filings, because intake clerks reject them on sight.
- Don’t list your EIN anywhere on the form, because it is irrelevant and confuses the clerk.
- Don’t sign in pencil or use a stamp signature, because both are treated as defective execution.
Pros and Cons of Filing on Your Own vs. With Help
| Filing on Your Own | Filing With an Attorney or Service |
|---|---|
| Saves the $300 to $1,500 attorney fee, helpful for small typos | Reduces rejection risk, especially for substance-vs-correction analysis |
| You control the timeline and can file the same day you discover the error | Attorneys catch hidden issues that may need a Certificate of Amendment instead |
| Builds familiarity with the bizfileOnline portal for future filings | Provides legal privilege for sensitive corrections like merger date errors |
| Avoids sharing internal documents with a third party | Handles correspondence with the office if a rejection notice arrives |
| Best for clear, single-word corrections like address typos | Best for multi-clause errors, fraud-adjacent issues, or post-merger fixes |
Pros of pro se filing
- Lower out-of-pocket cost, often just the $30 fee.
- Faster turnaround when the error is small.
- Direct control of the filing record.
- No need to forward sensitive documents externally.
- Educational; you learn the form for future use.
Cons of pro se filing
- Higher rejection rate without prior experience.
- No legal advice on whether COR-7 is even the right form.
- No buffer if the office issues a deficiency notice.
- Easy to misuse the fraud certification box.
- Personal liability if the correction is later challenged.
Key Entities That Interact With Form COR-7
The California Secretary of State, Business Entities Section, processes the filing. The Franchise Tax Board updates entity tax records based on the corrected name or address. The California Department of Tax and Fee Administration syncs sales-tax permits with the corrected record, and the Employment Development Department updates payroll-tax accounts.
Banks, title insurers, and contract counterparties pull from the same public record, so a clean COR-7 ripples outward through every commercial relationship. Statutes that govern the form include Corporations Code § 109 for corporations, § 17702.05 for LLCs, and § 15902.07 for limited partnerships.
Two related forms often confuse filers. A Certificate of Amendment changes the substance of an entity’s governing document, while COR-7 only fixes errors. A Statement of Information updates current officer and address data going forward, while COR-7 retroactively corrects what was filed.
| COR-7 Certificate of Correction | Certificate of Amendment |
|---|---|
| Fixes typos, omissions, or defective execution | Changes substantive provisions like share count or purpose |
| Relates back to original filing date | Effective on filing date or specified future date |
| $30 base fee | $30 base fee plus possible franchise-tax impact |
| Cannot change voting rights or member percentages | Required when voting rights or percentages change |
| Authorized by Corporations Code § 109 | Authorized by Corporations Code § 900 |
Recap of Agency Guidance
The Secretary of State’s filing tips bulletin confirms that COR-7 cannot be used when the underlying action was never validly authorized. In that situation the entity must rescind and refile rather than correct. The bulletin also clarifies that the relation-back rule does not protect third parties who relied on the defective document in good faith, a nuance courts applied in Boschma v. Home Loan Center and similar California decisions interpreting Corporations Code § 109(c).
For LLCs, the California Revised Uniform Limited Liability Company Act extends the same correction framework with parallel language. Foreign entities qualified to do business in California must file COR-7 with both the California Secretary of State and their home-state filing office to keep records synchronized.
FAQs
Do I need a lawyer to file COR-7?
No. Most simple typo corrections can be filed pro se using the bizfileOnline portal, but multi-clause or substance-adjacent corrections benefit from attorney review.
Can I use COR-7 to change my entity’s name?
No. A name change requires a Certificate of Amendment under Corporations Code § 900; COR-7 only fixes typos within the existing name.
Do I write my entity name in Item 1 with or without the comma before “INC.”?
Yes, include the comma exactly as it appears in the official record, because the database matches punctuation character-for-character.
Can I leave Item 8 blank?
Yes. Leaving Item 8 blank lets the correction relate back to the original filing date, which is the default and usually the desired result.
Is the EIN ever entered on COR-7?
No. Form COR-7 never asks for the IRS Employer Identification Number; only the Secretary of State file number belongs in Item 2.
Can I sign electronically?
Yes, through the bizfileOnline portal under the California Uniform Electronic Transactions Act, but paper filings still require wet-ink signatures.
What if I discover a second error after filing the first COR-7?
Yes, you can file a second COR-7 to correct the new error, as long as each correction is independently described and quoted in full.
How much does COR-7 cost?
No flat upcharge applies for most filers; the base fee is $30, plus optional expedited fees of $350, $500, or $750 per the service options page.
Can I file COR-7 for a dissolved entity?
Yes, but only to correct the dissolution document itself or a pre-dissolution filing; you cannot use it to revive the entity.
Do I need board approval to file COR-7?
No for ministerial typo fixes, yes if the correction touches matters that originally required board approval, such as a merger date.
Will COR-7 update my Franchise Tax Board records automatically?
No. You must separately notify the Franchise Tax Board and the CDTFA, because state agencies do not auto-sync to corrections.
Can I correct an officer’s title in Item 5?
Yes, provided the officer was actually serving at the time of the original filing; otherwise the correction misrepresents history and may be rejected.
What if my correction is rejected?
No new fee is required if you refile within 90 days of the rejection notice, per the filing tips page.
Is there a deadline to file COR-7?
No statutory deadline exists, but courts apply equitable defenses like laches when corrections are filed years after the error, so file as soon as you discover the defect.
