California Form LP-2 is the Amendment to Certificate of Limited Partnership that any domestic limited partnership formed under California law must file with the California Secretary of State to officially change information that already appears on its original Certificate of Limited Partnership (Form LP-1). The form updates the public record so banks, courts, lenders, and the Franchise Tax Board can rely on accurate partnership data, and a single missed checkbox or unsigned line can bounce the filing back and leave your records out of date for weeks.
Filing this form is not optional once a triggering change happens, and California Corporations Code § 15902.02 makes the general partners personally responsible for keeping the certificate accurate. The Secretary of State processes hundreds of thousands of business filings each year, and rejection rates for amendment-type forms hover around 20% because of small mechanical errors like missing the 12-digit file number or signing in the wrong block.
Here is what you will learn in this guide:

- ⚖️ Which California statutes trigger an amendment and when the duty to file kicks in
- 🧾 The exact documents and identifiers to gather before you open the PDF

What the Form Is and Who Must File It
Form LP-2 is the official paper that a California domestic limited partnership uses to amend its Certificate of Limited Partnership on file with the state. The certificate is the public document that created the LP in the first place, and any change to a fact stated on that certificate must be reported through this amendment. The current revision of the form is dated 08/2022, and you should always confirm you are using the latest version posted on the SOS LP forms page before filing.
The duty to file flows from California Corporations Code § 15902.02(b), which requires the general partners to amend the certificate within 30 days when a general partner is added or removed, when a stated term changes, or when any other listed fact becomes inaccurate. Failure to amend can expose the general partners to liability for losses caused by the false or stale public record, a consequence spelled out in § 15902.08.
Only domestic California LPs use Form LP-2. Foreign LPs registered in California must instead file Form LP-6, and limited liability partnerships use the GP/LLP series. If your entity is a general partnership that filed a Statement of Partnership Authority, you would amend with Form GP-1A, not LP-2.
Three named filers will appear throughout this guide:
- Maria Lopez, a general partner of Lopez Family Vineyards, LP, who is changing the LP name after a rebrand
- Carlos Nguyen, the managing GP of Pacific Coast Logistics, LP, who is adding a new general partner
- Janet Whitfield, GP of Whitfield Holdings, LP, who is changing the agent for service of process from herself to a corporate agent
Before You Start: Documents and Information You Need
Walking into Form LP-2 unprepared is the single biggest reason filers get bounced. The form is short, but every box keys to a fact already on file with the Secretary of State, and a mismatch with that record will trigger rejection. Gather every item below before you open the PDF, because the bizfile Online portal will time out and lose your entries if you stop to hunt for missing information.
Use this pre-filing checklist:
- 12-digit Secretary of State file number. This is the unique ID assigned to your LP when Form LP-1 was approved, and you can confirm it on the free Business Search tool. Without it the system cannot locate your record.
- Exact current LP name as recorded. Pull it letter for letter from the Business Search result, including punctuation and the LP designator. A trailing period or missing comma can cause rejection.
- Original Certificate of Limited Partnership (LP-1). You need to know what the certificate currently says so the amendment matches the field being changed.
- The new fact you are amending. Write out the exact new name, address, agent name, or general partner identity in final form before you start typing.
- Agent for Service of Process information. If changing the agent, have either the new individual’s full California street address or the corporate agent’s exact registered name on file under Corp. Code § 1505.
- General partner signature authority. Confirm who is authorized under your partnership agreement to sign the amendment, because an unauthorized signature voids the filing.
- Filing fee payment method. A $30 check payable to Secretary of State, or a credit card if filing through bizfile Online.
- Effective date decision. Decide whether the amendment is effective on filing or on a future date up to 90 days out, as allowed by § 15902.03.
- Contact information for return copy. A name, address, email, and phone for the person who should receive the filed-stamped copy.
- FTB account awareness. Confirm the LP is current on the $800 annual tax with the Franchise Tax Board, because tax suspension blocks SOS filings.
If any item is missing, stop and gather it. Filing without complete information leads to a rejection letter that can take 10 to 20 business days to come back, and your partnership keeps operating with stale public records the entire time.
Where to Get the Form and How to Access It
The official Form LP-2 PDF lives on the California Secretary of State LP forms library and is downloadable as a fillable PDF directly from this link. Always pull the form fresh from the SOS site rather than reusing a saved copy, because the agency updates revision dates and discards older versions during processing.
You can also complete the amendment online through bizfile Online, the state’s business filing portal launched in 2022. The portal walks you through the same fields as the paper form but validates the file number and current name in real time, which catches the most common rejection triggers before you pay the fee. Online filings are the agency’s preferred channel and the fastest path to a filed-stamped copy.
If you prefer paper, print the PDF on plain white 8.5” x 11” paper, single-sided, with no staples and no shrinking. The Secretary of State scans every paper filing, and shrunken or two-sided documents jam the scanner and trigger automatic rejection under the Business Entities filing standards. Use black ink only, and never use correction fluid because any visible alteration voids the document.
For filers who do not have reliable internet access, the SOS public counter at 1500 11th Street, Sacramento, CA 95814 keeps blank forms on hand. Call the Business Programs Division at 916-657-5448 before driving up, because counter hours change without notice.
Step-by-Step: How to Fill Out Form LP-2 Line by Line
Form LP-2 is a one-page form with seven numbered items plus a signature block. Every item maps directly to a fact already on the certificate, and the rule is simple: do not list anything you are not changing. Leaving non-amended fields blank is required, not optional, and filling in unchanged information is one of the most common rejection triggers cited by SOS examiners.
Item 1 – Secretary of State File Number
This field asks for the 12-digit file number the Secretary of State assigned to your LP when it was first formed. Type the number in the box at the top right of the form, with no spaces, no hyphens, and no leading letters even if your number begins with 200 or 199. Maria Lopez looks up Lopez Family Vineyards, LP on the Business Search page and types 200612345678 into Item 1.
If your file number begins with letters (older LPs sometimes had alphanumeric prefixes), include the letters exactly as shown on the search result. The most common mistake here is transposing two digits or grabbing the FTB entity number instead, and the consequence is automatic rejection because the SOS database returns no match. A widespread misconception is that the EIN or the FTB number can substitute for the SOS file number; it cannot, and only the 12-digit SOS number routes the filing to your record.
Item 2 – Name of Limited Partnership
Item 2 asks for the exact current name of the LP as it appears on the most recent certificate, not the new name you want. Type the name in all caps if your original was in caps, and match every comma, period, and LP or L.P. designator. Carlos Nguyen enters PACIFIC COAST LOGISTICS, LP because that is exactly how the name reads on the LP-1.
A frequent edge case is an LP whose name has already been amended once before. In that situation, use the current name on file, not the original 1998 name. The most common mistake is filers writing the new proposed name in Item 2, which causes the examiner to reject the form because the system cannot find a match. The misconception that drives this is that Item 2 is the “new name” line; it is not, the name change goes in Item 3.
Item 3 – Amendment to Name (Only if Changing the LP Name)
Item 3 asks for the new LP name only if you are changing the name. Leave this blank if you are amending something other than the name. The new name must comply with Corp. Code § 15901.08, which requires the words Limited Partnership, L.P., or LP and bars deceptively similar names. Maria Lopez writes LOPEZ HERITAGE VINEYARDS, LP in Item 3.
The nuance to know is that the SOS pre-clears name availability through the Name Availability Inquiry letter, and many filers reserve the new name on Form Name Reservation Request before filing LP-2 to lock it in. The most common mistake is choosing a name too similar to an existing entity, and the consequence is rejection with a 20-day wait for the letter explaining the conflict. The misconception here is that registering a fictitious business name (DBA) at the county level reserves the name with the state; it does not.
Item 4 – Amendment to Agent for Service of Process
Item 4 lets you change the agent designated to receive lawsuits and official notices. You can name an individual residing in California with a street address, or you can name a corporate agent that has filed a § 1505 statement. Janet Whitfield writes CT CORPORATION SYSTEM in Item 4a and leaves Item 4b blank because corporate agents do not list a street address.
If naming an individual, use a physical California street address only. PO boxes, mail drops, and out-of-state addresses are all rejected because the agent must be physically reachable for service of process. The most common mistake is writing a PO box, which results in immediate rejection. The misconception is that a UPS Store mailbox counts as a street address; it does not, and the filing will bounce.
Item 5 – Amendment to General Partner Information
Item 5 covers adding, removing, or changing the name or address of a general partner. Each general partner currently on file must be addressed if you are reorganizing GP membership, and you can attach an additional page if there are more than two changes. Carlos Nguyen writes ADD: SOFIA RAMIREZ, 1450 OCEAN AVE, LONG BEACH, CA 90802 to add Sofia as a new GP of Pacific Coast Logistics, LP.
The edge case worth knowing is that removing the last remaining general partner triggers dissolution under § 15908.01 unless a replacement is named in the same filing. The most common mistake is forgetting to include the new GP’s full address, which causes rejection because the certificate must show how to reach every general partner. The misconception is that limited partners go in this section; they do not, only general partners appear on the certificate.
Item 6 – Other Amendments
Item 6 is the catch-all for changes that do not fit Items 3 through 5, such as amending the LP’s stated term, adding a series provision, or restating optional clauses originally in the LP-1. Write a clear statement of the amended language, and attach a continuation page if needed. Whitfield Holdings, LP might write in Item 6: The term of the Limited Partnership is hereby extended from December 31, 2026 to December 31, 2046.
The nuance is that a complete restatement of the certificate uses Form LP-2A, the Restated Certificate of Limited Partnership, not LP-2. The most common mistake here is attaching pages of operating agreement language that does not belong on the public certificate, which leads to rejection because only certificate-level facts go on the public record. The misconception is that internal partnership agreement amendments must be filed; they do not, and only certificate facts under § 15902.01 belong on LP-2.
Item 7 – Future Effective Date (Optional)
Item 7 lets you delay the effective date of the amendment up to 90 days after filing, as authorized by Corp. Code § 15902.03. Enter the date in MM/DD/YYYY format, for example 07/01/2026. Leave blank if you want the amendment effective immediately upon filing.
The edge case is timing the amendment with a tax year for FTB purposes, which can save an LP the $800 minimum tax for the prior year if the formation or change crosses a year boundary. The most common mistake is entering a date more than 90 days out, which triggers automatic rejection. The misconception is that backdating works on Item 7; it does not, and the SOS will not accept any date earlier than the filing date.
Signature Block – Execution by General Partner(s)
Every LP-2 must be signed by at least one general partner under penalty of perjury, with name typed below the signature line. The signature block is at the bottom of the form, and the signer must be a current GP authorized under the partnership agreement. Maria Lopez signs in cursive on the signature line and types MARIA LOPEZ, GENERAL PARTNER directly underneath.
The edge case is when an entity (an LLC or corporation) serves as the general partner; in that case, an authorized officer of the entity-GP signs and indicates capacity, such as MARIA LOPEZ, MANAGING MEMBER OF LOPEZ MANAGEMENT LLC, GENERAL PARTNER. The most common mistake is having a limited partner sign, which voids the filing because limited partners have no authority to amend the certificate. The misconception is that an attorney or paralegal can sign on behalf of the GP; they cannot unless they hold a general partner role themselves.

How to File the Completed Form
California gives you three filing channels for Form LP-2, and the right choice depends on speed, cost, and whether you need a same-day filed-stamped copy. Each channel has its own quirks, and choosing the wrong one can add weeks to your processing time.
Online via bizfile. Submit the amendment through the bizfile Online portal at https://bizfileonline.sos.ca.gov/. The fee is $30, paid by Visa, Mastercard, American Express, or Discover. Standard processing runs about 5 business days, and you receive a digitally filed-stamped PDF by email. Save the email confirmation as your proof of filing.
By mail. Mail the signed paper form with a $30 check payable to Secretary of State to: Secretary of State, Business Entities Filings, P.O. Box 944228, Sacramento, CA 94244-2280. Mail processing currently runs 3 to 4 weeks, sometimes longer at year-end, per the SOS processing times page. Send by certified mail with return receipt to keep proof of filing.
In person. Drop the form at the SOS public counter at 1500 11th Street, 3rd Floor, Sacramento, CA 95814. Counter filings carry the regular $30 fee plus a $15 special handling fee payable as a separate check, authorized by Corp. Code § 12206. Counter processing typically delivers the filed copy within 24 hours, and you can pay the additional $350 preclearance or $750 expedited 24-hour fee for guaranteed turnaround under the SOS expedited services schedule.
Always keep a complete photocopy of the signed form and the front and back of the check or the bizfile receipt. That copy is your only proof if the SOS loses or rejects the filing.
What Happens After You File
Once the Secretary of State accepts your LP-2, it stamps the document with a filing date and updates the public record on the Business Search database, usually within 24 to 48 hours of acceptance. You will receive a filed-stamped copy back by email (online filings) or by mail (paper filings). Keep this copy with your partnership minute book, because lenders, escrow companies, and courts will request it.
If the filing is rejected, the SOS sends a rejection letter explaining the defect, and you have 90 days to refile without paying a new fee, provided you reference the original submission. After 90 days, the original fee is forfeited and you must pay another $30 with a fresh form. Common rejection reasons get fixed in minutes, but the lag time on the rejection letter (10 to 20 business days by mail) is the real cost.
The amendment is also reported automatically to the Franchise Tax Board, which uses the same SOS file number to track the LP’s $800 annual tax obligation. A name change does not change your FTB account, but adding a GP can affect K-1 reporting under IRC § 6031 and may require an updated Form 565 for the partnership return.
Mistakes to Avoid When Filling Out the Form
Form LP-2 is short, but the rejection rate is high because every box keys to an existing record. Here are the ten errors examiners flag most often:
- Wrong SOS file number. A single transposed digit causes automatic rejection because the system cannot locate your LP.
- Listing the new name in Item 2. Item 2 must be the current name; the new name belongs in Item 3 only.
- Filling in fields you are not changing. Unchanged items must stay blank, and filling them in triggers rejection for inconsistency with the existing record.
- PO box for an individual agent. Section 1502 requires a physical California street address, and a PO box voids Item 4.
- Limited partner signing the form. Only general partners can execute LP-2, and a limited partner signature is a fatal defect.
- Backdating Item 7. Effective dates earlier than the filing date are rejected on sight.
- Future effective date over 90 days out. The 90-day cap is statutory and the system blocks longer dates.
- Missing $30 fee or wrong payee. Checks must be payable to Secretary of State, not “California SOS” or “State of California.”
- Two-sided printing or stapled pages. Both jam the scanner and lead to rejection.
- Forgetting to attach LP-2A for a full restatement. A complete certificate restatement requires the LP-2A form, not LP-2 alone.
Each of these errors carries the same consequence: the filing bounces, your record stays stale, and you wait weeks for the rejection notice while operating with an inaccurate public record.
Do’s and Don’ts
Do’s:
- Do confirm the SOS file number on Business Search before typing it, because a wrong number is the single most common rejection reason.
- Do leave non-amended items blank, because the SOS examiner cross-checks every filled field against the existing record.
- Do keep a date-stamped copy of the signed form, because lenders and courts demand original-style documentation.
- Do use bizfile Online when possible, because real-time validation catches errors before payment.
- Do pay the $15 special handling for in-person filings if speed matters, because counter turnaround is 24 hours.
- Do confirm FTB tax status before filing, because a suspended LP cannot record amendments.
Don’ts:
- Don’t sign as a limited partner, because the signature is void and the filing fails.
- Don’t use correction fluid or visible cross-outs, because any alteration voids the document.
- Don’t mail with staples or two-sided printing, because the SOS scanner cannot process them.
- Don’t assume a DBA filing reserves your new name, because county fictitious business name filings have no effect at the state level.
- Don’t wait beyond 30 days after a triggering change, because § 15902.02 imposes the deadline.
- Don’t combine an LP-2 with a Statement of Information; those are separate filings on Form LP-1A and require their own fee.
Pros and Cons of Filing on Your Own vs. With Help
Pros of filing pro se:
- Lower cost. Self-filing costs $30 versus several hundred dollars for an attorney or filing service.
- Speed for simple changes. A name change or agent change online takes under 30 minutes.
- Direct control of timing. You choose the filing date and the future effective date.
- Familiarity with your records. You know your LP’s current information better than any third party.
- Bizfile validation. The portal catches mechanical errors that a lawyer would also catch, but for free.
Cons of filing pro se:
- Statutory traps. Missing a § 15902.02 deadline can shift liability to the GP personally.
- Restatement complexity. Full restatements require LP-2A and careful drafting an attorney handles better.
- Tax-year coordination. A poorly timed effective date can trigger an extra year of $800 FTB tax.
- Banking fallout. A name change requires updated bank signature cards, EIN reconciliation with the IRS under IRC § 6109, and revised loan documents.
- Litigation exposure. A defective amendment can be challenged years later in partnership disputes, and a pro se filer may not spot the defect until it’s too late.
Filing by Mail vs. Online vs. In Person
| Filing Method | Key Details |
|---|---|
| Online (bizfile) | $30 fee, 5 business days, credit card payment, real-time validation, digital filed-stamped copy |
| $30 fee, 3–4 weeks, check only, no validation, paper filed-stamped copy returned by mail | |
| In Person | $30 fee plus $15 special handling, 24-hour turnaround, check or money order, paper copy at counter |
FAQs
Can a limited partner sign Form LP-2?
No. Only general partners may sign the amendment. A limited partner signature voids the filing under California Corporations Code § 15902.04 and triggers immediate rejection by the SOS examiner.
Is there a deadline to file Form LP-2 after a change?
Yes. California Corporations Code § 15902.02(b) requires general partners to file an amendment within 30 days of learning the certificate is inaccurate, or face personal liability for resulting losses.
Do I write my LP’s old name or new name in Item 2?
No new name. Item 2 is for the current name on file. The new name goes in Item 3 only when you are amending the LP name.
Can I list a PO box in Item 4 for the agent for service of process?
No. California requires a physical street address for an individual agent under Corporations Code § 1502. PO boxes, mail drops, and UPS Store boxes all trigger rejection.
How much does it cost to file Form LP-2?
Yes, there is a $30 fee. In-person filings add a $15 special handling fee. Expedited 24-hour service costs an extra $350, and 4-hour service costs $500.
Can I amend two different items on one LP-2?
Yes. A single LP-2 can address Items 3 through 6 in any combination. Each amended item is filled in, and unchanged items remain blank.
Do I need to file a new LP-1 instead of LP-2?
No. Form LP-1 forms a new partnership; LP-2 amends an existing one. Use LP-1 only for a brand-new LP, never for changes to an existing entity.
Is bizfile Online faster than mail filing?
Yes. Online filings process in about 5 business days, while mail filings take 3 to 4 weeks. Online filings also include real-time validation that catches errors before submission.
Can I list a future effective date for the amendment?
Yes, up to 90 days after filing under Corporations Code § 15902.03. Enter the date in MM/DD/YYYY format in Item 7. Backdating is not permitted.
Does an LP-2 update my FTB records automatically?
Yes. The Franchise Tax Board pulls SOS data daily, so amendments to name, agent, and GP are reflected within 1 to 2 weeks. The $800 annual tax obligation does not change.
Do I need to attach my partnership agreement?
No. Only certificate-level facts under § 15902.01 belong on LP-2. Internal partnership agreement amendments stay private and are never filed with the state.
Can I file Form LP-2 if my LP is suspended by the FTB?
No. A suspended LP cannot record amendments until the FTB issues a Certificate of Revivor. Confirm tax status before filing to avoid wasted fees.
Do I have to amend if I just change my LP’s mailing address?
No. The mailing address lives on Form LP-1A, the Statement of Information, not on the certificate. Use LP-1A for address-only changes.
What if I make a mistake on the LP-2 after filing?
Yes, you can fix it. File a second LP-2 correcting the error, or use Form LP-3 for a Certificate of Correction if the SOS already accepted the defective filing.
