FinanceThe First Notice of Loss Process, From Inbox to Adjuster
How the first notice of loss process works in commercial claims: what a notice holds, the US 15-day acknowledgment clock, coverage checks, triage.
A first notice of loss (FNOL) is the first report of a claim to an insurer. In personal lines it is often a phone call or a form in an app. In commercial lines it is usually an email from a broker with forms, photos and invoices attached. Either way it opens the claim file and, under the model rules US states adapt, starts a regulatory clock.

This guide covers what a notice holds, which deadlines it starts, and the intake steps between the inbox and the adjuster.
What a first notice of loss is, and when the clock starts
The National Association of Insurance Commissioners (NAIC), which writes the model laws US states adopt, sets the starting point in its claims settlement model regulation: "Every insurer, upon receiving notification of a claim shall, within fifteen (15) days, acknowledge the receipt of such notice unless payment is made within that period of time." It adds: "Notification given to an agent of an insurer shall be notification to the insurer" (NAIC Model Regulation 902).
The practical consequence is that a notice does not start counting when a claims handler opens it. It counts from the moment it reaches the insurer or its agent, which includes a shared claims inbox nobody has read yet.
NAIC models are templates, and each state adopts its own version. California is one example: within 15 calendar days of notice an insurer must acknowledge it, provide the forms and instructions the claimant needs, and "begin any necessary investigation of the claim" (10 CCR 2695.5).

Commercial notices often come on ACORD forms, the standard insurance forms used across the US market: form 1 is the Property Loss Notice, form 2 the Automobile Loss Notice, form 3 the Liability Notice of Occurrence or Claim (ACORD forms index).
Around the form come photos, a police or fire report, invoices, repair estimates and the broker's own summary in the body of the email. The policy number may be on the form, in the email, in the subject line, or missing. The same facts appear in several places and do not always agree: a loss date in the email that differs from the form, a location that is not the one on the schedule, last year's policy number.
The deadlines that start at notice
| Rule | Acknowledge the notice | Accept or deny |
|---|---|---|
| NAIC Model Regulation 902 | Within 15 days of notification | Within 21 days of proof of loss, for first-party claimants |
| California, 10 CCR 2695.5 and 2695.7 | Within 15 calendar days, and begin the investigation | Within 40 calendar days of proof of claim |
| UK, FCA ICOBS 8.1.1R | No fixed number of days: handle claims promptly and fairly | No fixed number of days: settle promptly once terms are agreed |
The deadlines come with conduct rules. The NAIC's Unfair Claims Settlement Practices Act lists among unfair practices "failing to acknowledge with reasonable promptness pertinent communications with respect to claims" and "failing to adopt and implement reasonable standards for the prompt investigation and settlement of claims" (NAIC Model Act 900). In the UK, the FCA's rule asks insurers to "provide reasonable guidance to help a policyholder make a claim and appropriate information on its progress" (ICOBS 8.1).
Intake is also where the claim file's record begins. The NAIC model requires documentation detailed enough "to permit reconstruction of the insurer's activities relative to each claim", and each relevant document "noted as to date received, date processed or date mailed." Those dates are first written at intake.
The intake steps: read, check cover, triage, open the claim
- Read the notice and every attachment: insured, policy, date and place of loss, peril, description, parties involved, estimate.
- Match the policy: in force on the loss date, named insured, location or vehicle on the schedule.
- Check cover: the peril against the insuring agreement and exclusions, the limits, the deductible.
- Triage: severity and complexity, which team, and whether a specialist is needed for a large loss, an injury or likely litigation.
- Open the claim: create the file in the claims system with each document and its date received, send the acknowledgment, and request what is missing.
- Hand over to the adjuster, with what was checked and what was not.
The first five steps are reading and comparing. Coverage decisions, reserves and payment belong to the adjuster.
Fraud screening belongs at intake, but decides nothing there
A study for the Coalition Against Insurance Fraud estimates property and casualty fraud in the United States at $45 billion a year, out of $308.6 billion across all lines (CAIF, 2022). It is an estimate: the property and casualty figure is calculated as 10 percent of losses and loss adjustment expenses, not measured claim by claim.
Intake is where the first inconsistencies show: a loss date close to the start of cover, an address that differs from the schedule, an invoice dated before the loss. A flag at intake goes to the special investigations unit with its evidence. Intake never denies a claim.
Where AI agents fit, and what regulators expect of them
In December 2023 the NAIC adopted a model bulletin on insurers' use of artificial intelligence. It expects insurers to maintain a written program for AI systems "that make, or support decisions related to regulated insurance practices", covering areas that include "claim administration and payment, and fraud detection" (NAIC Model Bulletin). Adoption is state by state, so check what your state has taken up. An agent at intake therefore sits inside the insurer's own governance: documented, tested and monitored like any other system that supports a claims decision.
Within that frame the split is simple. The agent reads the notice and its attachments, checks them against the policy, routes the claim by severity and prepares the file. The adjuster keeps every coverage, reserve and payment decision. Claims intake is one of the six workflows Mirage runs for insurers' operations teams, and the same read, check, route pattern runs through know-your-customer periodic reviews on the banking side.
What policyholders notice: speed and status updates
J.D. Power's 2026 U.S. Property Claims Satisfaction Study, based on 5,093 homeowners customers, found that digital tools were used by 38 percent to report the first notice of loss, 49 percent to submit photos and 45 percent to receive updates. The average repair took 29.6 days and final payment came after 40.7 days on average (J.D. Power).
Those are homeowners figures, not commercial ones. They still show that the notice is the start of a long process, and that what a claimant sees is mostly the status updates in between. A clean file at intake is what makes those updates possible.

It is the intake of a new claim: reading the notice and its attachments, matching the policy, checking cover, triaging the claim by severity and complexity, opening the file in the claims system and sending the acknowledgment, then handing the file to an adjuster.
The insured and policy number, the date, time and place of the loss, what happened and the peril involved, the people and property involved, and any reports, photos, invoices or estimates. Commercial notices often arrive on ACORD forms 1, 2 or 3.
Under the NAIC model regulation, 15 days from notification. States adopt their own versions: California requires acknowledgment within 15 calendar days and the start of the investigation in the same period. The UK sets no fixed number of days but requires claims to be handled promptly and fairly.
Sorting each new claim by severity and complexity so it reaches the right team: simple claims to fast handling, large losses, injuries or likely litigation to specialists, and suspicious ones to the special investigations unit.
A standard form used across the US insurance market to report a loss. ACORD form 1 is the Property Loss Notice, form 2 the Automobile Loss Notice and form 3 the Liability Notice of Occurrence or Claim.
It can handle intake: read the notice and attachments, check them against the policy, route the claim and prepare the file. Coverage, reserve and payment decisions stay with the adjuster, and US insurers are expected to govern such systems under the NAIC's AI bulletin where their state has adopted it.
READY TO AUTOMATE?
The documents are already in. The coordination is still done by hand.
What one file needs sits in a document store, a core system and a workflow tool. Mirage reads each document, checks it against your systems and your rules, and sends only what needs judgement to a person.
