How to file a business insurance claim, step by step
Who to notify, what the policy requires you to do first, what to send, and the deadlines insurers must meet once a business claim is reported.
To file a business insurance claim, notify the insurer (or the broker who placed the policy) promptly and in writing, protect the property or people involved from further harm, record everything, and send the insurer every demand, notice or legal paper the day it arrives. Which policy responds, and therefore what you have to do and by when, depends on whether the loss is to your own property or a claim is being made against you.
The standard forms spell out your duties after a loss. Miss them and the insurer may reduce or deny the claim even though the underlying loss was covered, which is why the first 48 hours matter more than most owners expect.
Start by sorting the loss: first-party or third-party
A first-party coverage claim is your own loss: a fire, a burst pipe, a stolen delivery van, a ransomware shutdown. A third-party coverage claim is someone else's claim against you: a customer's slip-and-fall, a client's allegation that your work cost them money, a neighbor's damaged building. The two follow different paths.
| Type of loss | Usual policy | First move | Where to read more |
|---|---|---|---|
| Fire, storm, theft, water damage | Commercial property | Secure the site, report the loss, begin documenting | the commercial property claim process, step by step |
| Closure or slowdown after a covered loss | Business income and extra expense | Report with the property claim, start tracking lost sales and extra costs | documenting a business interruption claim, from day one to final payment |
| Injury or property damage to a customer or vendor | General liability | Report the incident even if no claim has been made | premises liability: how slip-and-fall claims are handled |
| Lawsuit or demand letter | General liability, professional, EPL, D&O | Send the papers to the insurer immediately | when your business is sued: working with your insurer |
| Employee injury | Workers' compensation | Report to the carrier and, where required, the state | the workers' comp claims process for employers |
| Vehicle accident | Commercial auto | Safety, police, exchange information, report | what to do after an accident in a company vehicle |
| Ransomware, data breach | Cyber | Call the carrier's breach hotline before hiring vendors | what happens when you file a cyber claim |
What the standard forms require of you
Read the "duties in the event of loss" condition in your own policy. On the ISO commercial property coverage form (CP 00 10 10 12), the insured must do the following after a loss:
- Notify the police if a law may have been broken.
- Give the insurer prompt notice, with a description of the property involved.
- Describe, as soon as possible, how, when and where the loss happened.
- Take all reasonable steps to protect the covered property from further damage, keep a record of those expenses, and if feasible set damaged property aside for examination.
- On request, provide complete inventories of damaged and undamaged property, with quantities, costs, values and the amount claimed.
- Permit inspection of the property and of your books and records.
- Send a signed, sworn proof of loss within 60 days after the insurer's request (see the sworn proof of loss: what it is, when it's due and how to prepare it).
- Cooperate in the investigation or settlement.
The same form lets the insurer examine any insured under oath. The suit-limitation condition in the companion Commercial Property Conditions form (CP 00 90) bars legal action unless it is brought within two years after the date of the direct physical loss, according to the FC&S summary on PropertyCasualty360. Many states change that period by amendatory endorsement or statute, so check the endorsements in your policy.
Liability claims run on a different clock. The ISO general liability form (CG 00 01) asks you to see that the insurer is notified "as soon as practicable" of an occurrence or offense that may result in a claim, and, once a claim or suit arrives, to send copies of demands, notices and summonses immediately. It also bars you from voluntarily making a payment, assuming an obligation or incurring an expense, other than for first aid, without the insurer's consent. Manuscript and carrier-specific forms differ, so confirm the wording in your own policy. The consequences of delay are covered in notice of claim and late notice: why timing matters.
The first 48 hours
Make people and property safe. Call emergency services where needed. Then stop the damage from spreading: board openings, shut off water, move stock, hire an emergency mitigation vendor. The policy expects "reasonable steps," and the cost of them is normally part of the claim, so keep receipts.
Do not throw anything away. Damaged equipment, inventory and building materials are evidence. Photograph and video everything before cleanup. If you must dispose of spoiled or hazardous material, document quantity and value first and tell the adjuster.
Report the loss. Call the claims number on your policy or declarations page, or your broker, and follow up in writing so the date of notice is fixed. A broker who holds an agency appointment from the carrier may be treated as the carrier's agent for notice purposes in some states and not in others. Until you have a claim number, send notice to the insurer too, and copy the broker.
Report even if you are unsure the loss is covered or exceeds the deductible. The insurer, not you, decides coverage. A small incident that never becomes a claim costs nothing to report; an unreported one that turns into a lawsuit two years later can become a late-notice fight.
Limit what you say. Give facts, not conclusions. Do not tell a customer or claimant that you are at fault, do not promise payment and do not guess at cause. "The pipe burst Thursday night and we found water at 6 a.m." is a fact; "our plumber botched it" is a problem.
What to include in the first notice
- Policy number, named insured and a contact who can answer calls.
- Date, time and location of the loss.
- A short, factual account of what happened and what has been done to protect the property.
- Names and contact details of injured people, witnesses and other parties, plus any police or fire report number.
- Whether anything is still at risk and whether the business is closed or operating at reduced capacity.
Ask for the claim number, the adjuster's name and direct line, and the claim forms. Under the NAIC Unfair Property/Casualty Claims Settlement Practices Model Regulation, an insurer must acknowledge a claim within 15 days of notification and provide the necessary forms, instructions and assistance in that time.
What the insurer owes you, and how fast
State law, not the policy, sets most of the claims-handling clock. The NAIC model regulation (see its Model 902) is a template that states adopt in different forms. Its time limits give a sense of the usual pattern:
| Step | NAIC model benchmark |
|---|---|
| Acknowledge the claim | Within 15 days of notice |
| Accept or deny after receiving a properly executed proof of loss | Within 21 days, or a written explanation of why more time is needed |
| Status letters if the investigation continues | 45 days after initial notice, then every 45 days |
| Pay once liability is determined and the amount is not in dispute | Within 30 days |
| Denial | In writing, referring to the specific policy provision |
Individual states differ. California's regulation, 10 CCR 2695.7, requires acceptance or denial within 40 calendar days of proof of claim and payment within 30 calendar days of acceptance. Texas Insurance Code section 542.055 requires an insurer to acknowledge, start investigating and request needed items within 15 days of notice (30 business days for eligible surplus lines insurers), and section 542.056 sets a deadline of the 15th business day after it receives all requested items to accept or reject. Check your own state on its insurance department site, or through workers' comp and benefits requirements by state and the state guides such as California and Texas.
A hypothetical example
Say a 20-seat restaurant (see Restaurant insurance) in Ohio has a grease fire in the kitchen at 11 p.m. on a Friday. The owner calls the fire department, then the next morning calls the claims number on the policy and emails the broker with photos taken before the cleanup crew arrives. The adjuster is assigned Monday. The owner keeps the hood system service records, the last two years of profit-and-loss statements and a list of damaged equipment with age and purchase price. Because the restaurant is closed, the owner also opens a separate ledger for payroll kept on, rent and extra costs, which will feed the income claim. Within 60 days of the insurer's request, the owner returns the sworn proof of loss, reviewed with the broker beforehand. None of this guarantees payment, since coverage depends on the policy, but it removes the avoidable reasons for delay.
Keep a claim file
Create one folder, physical or digital, holding the policy and all endorsements, the notice and any acknowledgment, every email and letter, call notes (date, person, what was said), photos, estimates, receipts and invoices. The business insurance claim checklist lays out what to collect. The file is what you use if the claim stalls, goes to the appraisal clause in commercial property disputes or ends in a dispute; see what to do when your business insurance claim is denied.
Common ways a valid claim goes wrong
- Waiting until the repair bill arrives, or until a demand letter becomes a lawsuit.
- Signing a release or a proof of loss without reading the amount and the cause-of-loss statement.
- Paying a claimant yourself to "make it go away" and then asking the insurer to reimburse.
- Assuming that telling the broker, the building manager or the lender counts as notice to the insurer.
- On claims-made policy forms, reporting after the policy and any extended reporting period have ended.
More are collected in the most common mistakes businesses make with claims. Your claims history can affect renewal pricing, but reporting a covered loss is almost always right; see do claims raise business insurance premiums?.
Key takeaways
- Report promptly and in writing, to the insurer or the broker, and get a claim number and adjuster contact.
- Protect the property, keep damaged items and receipts, and photograph everything before cleanup.
- Send every demand, notice and summons to the liability insurer at once, and do not pay or admit liability on your own.
- Know the policy's deadlines (sworn proof of loss, suit limitation) and the state's claims-handling rules; they vary by state and by form.
- Keep one organized claim file; it is your best tool if the claim becomes a dispute.
