California insurance claim investigation time is not open-ended. After an insurer receives proof of claim, California rules generally give it 40 calendar days to accept or deny the claim, in whole or in part. If it needs longer, it must send a written status letter and keep updating you. That clock is separate from your deadline to file a lawsuit.

This guide covers the insurer’s timeline after a California car accident. It explains what starts the clock, what a status letter should say, when payment is due, and why a slow claim does not pause your right to sue. For what to say on the phone, read the firm’s guide to handling insurance adjusters after a car accident.
What Starts California Insurance Claim Investigation Time
The 40-day standard does not start when the crash happens. Under California Code of Regulations, title 10, section 2695.7, the insurer must act after it receives proof of claim. Proof of claim is the information reasonably needed to decide coverage, fault, and the amount that may be owed. A short phone report is usually notice. It is not always proof.
For an injury claim, useful proof often includes the date, the location, the vehicles, the people involved, and enough medical information to connect treatment to the crash. A repair estimate can be totaled quickly. An injury that is still being treated cannot.
Keep a simple record from the first day:
- The date you reported the crash, the claim number, and the adjuster’s name.
- Photos, the traffic collision report if you have it, and repair estimates.
- Medical bills, visit summaries, and wage notes, each labeled by date.
- Every letter or email from the insurer, saved with its send date.
If the insurer says it is still waiting on proof, ask in writing what is missing. A vague request for “everything” is not a reason to sign a broad medical release. If you have not saved photos, witness names, or treatment records, start with the firm’s checklist of what to do after a car accident in California.
The 40-Day Accept or Deny Rule.
Once proof of claim is in, section 2695.7(b) says the insurer shall immediately. But in no event more than 40 calendar days later, accept or deny the claim, in whole or in part. Count calendar days, not business days. A partial acceptance is allowed. Unless the claim is denied entirely, the amounts accepted or denied must be documented in the claim file.
A written denial has to explain itself. On a first-party claim, which is a claim on your own policy, the letter must list each basis the insurer is using. It must also give the factual and legal reasons then within the insurer’s knowledge. If a policy exclusion or a statute is the reason, the letter must cite it and explain how it applies.
On a third-party claim, which is a claim against the other driver’s insurer, a denial or a dispute over fault or damages must also be in writing. The notice must say that you may ask the California Department of Insurance to review claim practices. It must include that unit’s address and phone number.
One exception matters after a car crash. The 40-day timeframe does not apply to automobile repair bills under collision or comprehensive coverage governed by Insurance Code section 560. Injury liability, medical payments, and uninsured or underinsured motorist claims are not the same as a body-shop invoice. Do not let a slow repair stand in for your injury timeline.
The California Department of Insurance publishes the Fair Claims Settlement Practices Regulations. Its guide, So You’ve Had an Accident, What’s Next?, walks through practical next steps after a crash.
When the Insurer Says It Needs More Time
Forty days is the standard. It is not a promise that every file closes on day 40. Section 2695.7(c) allows more time when the insurer cannot yet decide. The condition is a written notice inside those first 40 days. The letter must say what information is still needed and why a decision cannot be made yet.
After that first letter, the insurer must write again every 30 calendar days. The updates continue until it makes a decision or until notice of a lawsuit is served. If the decision depends on a future event, such as a doctor’s opinion, the notice must describe that event and estimate when a decision can be made. A voicemail that says “we are still reviewing” does not replace the letter.
Use the status letter. Reply only to the items it actually requests, and note the date you responded. If a letter asks for records from years before the crash, ask which dates and which providers are tied to this collision. You can answer a reasonable request without turning over your entire medical history.
- Save the status letter and write down the date you received it.
- List each item the insurer says is missing.
- Send only those items, and keep a copy of what you sent.
- Calendar 30 days out and watch for the next written update.
- If the next letter repeats the same request, ask what is still missing.
Silence after day 40, or a string of identical letters that never name the missing fact, is a reason to get advice. The firm’s overview of the California personal injury claims process shows how investigation, negotiation, and a lawsuit fit together when a claim stalls.
| Step | What the regulation generally requires | What you should keep |
|---|---|---|
| Proof of claim is received. | The 40-calendar-day accept-or-deny period begins. | Keep what you sent and the date the insurer received it. |
| Day 40 arrives. | Accept or deny the claim, or send a written need-more-time notice. | Keep the decision letter or the status letter. |
| Each later 30-day mark. | Send a new written status notice until a decision or a lawsuit notice. | Keep each update and your dated reply. |
| The insurer accepts the claim. | Pay within 30 calendar days once any required release is signed. | Keep the release draft and the payment date. |
| Your own lawsuit deadline. | These letters do not pause the time you have to file suit. | Keep the crash date and any public-agency notice deadline. |
Payment After the Insurer Accepts the Claim
Acceptance and payment are two different steps. Section 2695.7(h) says that after the insurer accepts the claim, in whole or in part. And after it receives any properly executed release it requires, it shall immediately tender payment. That payment is due in no event more than 30 calendar days later. The amount is the amount it accepted, not a new number invented at the payment stage.
Read the release before you sign it. A release can give up injury claims from the crash, including treatment you have not had yet. If you are still in care, or if lost wages are still adding up, do not sign the first draft the day it arrives. Ask which claims the release covers and whether any amount is being left open.
A late payment after a signed release is a different problem from a slow investigation. Note the date the insurer received the release. Follow up in writing if 30 calendar days pass with no payment and no explanation. For the kinds of losses a car-crash claim can include, see the firm’s California car accident lawyer page.
A Slow Investigation Does Not Pause Your Lawsuit Deadline
Status letters can continue for months. They do not add time to sue. Many California personal injury lawsuits must be filed within two years of the injury. Important exceptions exist, and a claim against a public agency can require notice much sooner. Settlement talks do not, by themselves, protect that date.
Section 2695.7(f) requires most insurers to give written notice of a time limit they may later use to deny a claim. That notice is generally due at least 60 days before the date expires. If the claim was first received inside that window, notice is due immediately. For a first-party uninsured-motorist matter, the advance notice is at least 30 days. The duty does not apply once a claimant is represented by counsel. Treat the notice as a backstop, not as your calendar.
The firm’s article on the California car accident statute of limitations explains the two-year period, delayed discovery, and government-claim deadlines. Use this article for the insurer’s clock. Use that one for yours.
How to Track California Insurance Claim Investigation Time
A folder beats a memory. Put the crash date on the first page. Add the date the insurer acknowledged the claim. Then add the date you believe proof of claim was complete. If those dates are unclear, ask the adjuster to confirm them in writing. You are building a timeline, not an argument.
Check three things each time a letter arrives. First, does it accept, deny, or ask for more time? Second, if it asks for more time, does it name the missing item? Third, does it give a date or a future event that would let the insurer decide? A letter that only says the file remains open fails those checks.
Respond in writing even when you also call. A short email can say what you sent, the date you sent it, and the claim number. Save the sent copy. If you mail paper, keep the receipt. Phone promises are hard to prove later, and the regulation’s duties are written duties.
Watch for these stalls:
- The same “we need more information” letter, with no new item named.
- A request for records that predate the crash by many years.
- A denial that cites a policy section but never explains it.
- A payment that arrives only if you sign a release the same week.
- No letter at all after the first 40 calendar days.
None of these points proves the insurer broke a rule. Each one is a reason to slow down and get the file reviewed. Bring the letters, the medical bills you have so far, and the crash date. Do not wait for a “final” offer if a lawsuit deadline is close.

Frequently Asked Questions
How long can a California insurer investigate a car accident claim?
After proof of claim, the insurer generally has 40 calendar days to accept or deny the claim, in whole or in part. If it cannot decide, it must send a written explanation inside those 40 days and repeat that notice every 30 days. Ordinary collision or comprehensive repair bills can follow a different repair statute.
Does “still investigating” stop the 40-day clock?
No. More time is allowed only with a written notice that names the missing information and the reason for the delay. Then a fresh written notice every 30 calendar days. A phone message that the file is under review does not meet that requirement.
How long does the insurer have to pay after it accepts?
After acceptance, and after it receives any release it properly requires, the insurer generally must tender payment within 30 calendar days. Read the release first. Signing it can end your right to seek more compensation for the same crash.
Will a long investigation extend my deadline to sue?
No. Investigation letters do not pause the lawsuit deadline. Many California injury cases must be filed within two years of the injury, and some government claims require notice much sooner. Get advice before you rely on an adjuster to protect that date.
What if the denial letter is vague?
A first-party denial should state each reason and the facts, law, or policy language behind it. A third-party denial, or a dispute over fault or damages, should be in writing and should explain how to contact the California Department of Insurance. If the letter does not do that, ask for the specific basis before you treat the denial as final.
