An insurance company investigates a claim to confirm it is legitimate, work out who was at fault, and decide how much, if anything, it has to pay. Almost every claim goes through some version of this review, so an investigation by itself does not mean you did anything wrong. For an injured person, though, a long investigation is often also a way for the insurer to delay, look for reasons to pay less, and hope you settle for a smaller amount than your case is worth.
What the company is actually doing during that review, and how much leverage you have while it drags on, depends heavily on one thing: whether the insurer holds your policy or the policy of the driver who hit you.
Why Would an Insurance Company Investigate a Claim?
When a claim is filed, the insurer will not simply take the claimant’s word for what happened. It runs a structured review to protect against fraud and to limit what it pays out. In practice, an investigation comes down to four questions the insurance company wants answered:
- Is the claim legitimate, or does it show signs of fraud or exaggeration
- Does the policy actually cover this loss on the date it happened
- Who was at fault, and by how much
- What are the injuries and damages genuinely worth
Verifying legitimacy protects the insurer and, in theory, keeps premiums fair for honest policyholders. But the same process gives the company room to question your version of events, minimize your injuries, and shift blame onto you. Understanding what the insurer is looking for helps you keep the investigation from being used against you.
What “Under Investigation” Actually Means
If an adjuster tells you your claim is “under investigation,” it usually means they are reviewing two things at once: liability (who caused the crash) and coverage (whether an active policy applies). It is often used as a broad, deliberately vague label that covers everything from pulling the police report to checking whether their own insured paid the premium.
Hearing that your claim is under investigation is not a denial and is not a signal that you are a suspect. In most cases it is a normal step. The concern for an injured claimant is timing. The longer a claim sits “under investigation,” the more pressure builds to accept a quick, low offer, especially if medical bills are piling up.
What Insurance Adjusters Look For
The investigation is handled by an insurance adjuster, the person assigned to value your claim and recommend how the company should respond. An adjuster works for the insurer, not for you, and generally has three jobs:
Determining coverage: confirming the claimed event is actually covered under the policy in question
Assessing damages: estimating the cost of the claim, whether it involves vehicle damage, property damage, or a personal injury
Negotiating a settlement: arriving at a payout based on what the insurer believes the claim is worth
To do this, the adjuster gathers and scrutinizes evidence. That typically includes the police or crash report, photos of the damage, repair estimates, medical records, and statements from you and any witnesses. Every one of those pieces is being checked for consistency, so small contradictions between your account and the documents can slow a claim down or become a reason to reduce it.
Coverage Investigations: What Insurers Verify
Part of the review has nothing to do with your injuries and everything to do with the policy behind the claim. A coverage investigation is the insurer confirming that a valid policy actually responds to the loss. On the at-fault driver’s side, the company may be checking:
- Whether their insured actually paid the premium and the policy was in force on the date of the crash
- Whether the driver had permission to use the vehicle
- Whether an excluded driver was behind the wheel
- Which policy limits apply to the loss
These checks matter to you because they decide how much money is even available. If the driver who hit you was uninsured, excluded, or driving without permission, the at-fault policy may not pay, and your own uninsured or underinsured motorist coverage may need to step in instead. That is one reason it helps to know exactly what coverage is on the table early.
Red Flags and Signs of Insurance Fraud
A large part of any investigation is fraud detection. Insurers watch for patterns that deviate from a typical, honest claim, and certain things reliably draw a second look:
- Inconsistencies in the story: an account that changes over time or conflicts with the evidence or witness reports
- Exaggerated claims: damages that appear far higher than the actual loss
- A history of frequent claims: especially several past incidents that look similar
- Delayed reporting: waiting to report the incident without a reasonable explanation
- Missing documentation: no receipts, no police report, or no medical records to back up the claim
The most common types of fraud insurers guard against include staged accidents, fabricated or inflated property damage, overstated theft claims, and false or exaggerated injuries. Honest claimants sometimes trip these red flags by accident, usually by delaying medical care or giving inconsistent statements, which is exactly why careful documentation matters so much.
How Insurers Investigate Personal Injury Claims
Injury claims get their own layer of scrutiny because the money often turns on how serious the harm is. Here the adjuster focuses on two things: whether the injury fits the accident, and what the medical records show.
Assessing the Injury
The adjuster examines the circumstances of the incident to decide whether the reported injury is consistent with how the accident is described. They may visit the scene to gather evidence and interview witnesses to get independent accounts that either back up or contradict the claim. A minor-looking collision paired with a serious injury claim, for example, is something an insurer will probe closely.
Reviewing Medical Documentation
Medical records are the backbone of an injury claim, and the insurer reviews them carefully to verify the timeline of treatment and confirm that the injuries claimed match what doctors actually documented. They look at the initial reports created right after the accident and any follow-up evaluations that show how the injury developed. A common tactic is to comb these records for pre-existing conditions or gaps in treatment, then argue that your pain came from something other than the crash. Getting prompt medical care and following through on treatment protects both your health and your claim.
Surveillance and Social Media in Claim Investigations
Modern investigations are not limited to paperwork. Your digital footprint can either support or undermine a claim, and insurers know it.
Social Media Scrutiny
Insurance investigators routinely review public social media accounts during a claim, looking for anything that contradicts what you have reported. A person claiming a serious back injury who posts photos hiking or playing sports can expect those posts to resurface during negotiations. Even harmless check-ins and status updates can be pulled out of context and used to question how hurt you really are.
Surveillance and Electronic Evidence
In higher-value claims, insurers may hire investigators to conduct in-person surveillance or gather electronic evidence such as time-stamped photos, videos, and location data. The goal is to catch activity that seems inconsistent with the injuries described. None of this is a reason to hide from normal life, but it is a strong reason to be accurate and consistent about your limitations from the start.
How Long Can an Insurance Investigation Take?
An investigation can run anywhere from about a week to several months, depending on the type of claim, the number of parties, and how complicated the facts are. A straightforward fender-bender resolves quickly. A serious injury claim with disputed fault and heavy medical treatment takes longer.
Illinois law does not let insurers stall indefinitely. Under the state’s improper claims practices rules, an insurer cannot refuse to pay a claim without conducting a reasonable investigation, and it must acknowledge communications and affirm or deny coverage within a reasonable time (215 ILCS 5/154.6). Insurers are also required to adopt reasonable standards for the prompt investigation and settlement of claims. When a company drags out an investigation as a strategy rather than a genuine need, that delay can cross the line into bad faith.
The practical danger of a slow investigation is your deadline. In Illinois you generally have two years from the date of the injury to file a lawsuit (735 ILCS 5/13-202). That window closes faster in one common situation. If the vehicle that hit you belonged to a city, village, county, transit agency, or other local public entity, you generally have only one year to sue (745 ILCS 10/8-101), and an adjuster who keeps the file “under investigation” for ten months has effectively taken your case. A stalled claim is a reason to act, not to wait.
What Illinois Law Says About Insurance Investigations
Illinois regulates how insurers handle claims. How much those rules actually help you, though, turns on whose insurance company is doing the investigating.
Insurers Must Investigate in Good Faith
The Illinois Insurance Code requires companies to handle claims honestly and promptly. Refusing to pay a claim without a reasonable investigation, failing to affirm or deny coverage within a reasonable time, and failing to attempt a fair, prompt settlement once liability is clear are all listed as improper claims practices (215 ILCS 5/154.6). An insurer is allowed to investigate, but it is not allowed to use “investigation” as an excuse to avoid paying a valid claim. Those standards are supervised by the Illinois Department of Insurance, which accepts consumer complaints, so a written complaint to the Department is often a practical step when a file sits untouched.
The Cost of Vexatious and Unreasonable Delay
When an insurer’s delay or refusal to settle is vexatious and unreasonable, an Illinois court can order it to pay reasonable attorney fees and costs plus an additional amount. The statute sets a ceiling on that extra amount rather than a formula: it may not exceed any one of 60% of what the court or jury finds you are entitled to recover, $60,000, or the excess of that recovery over what the company had offered in settlement (215 ILCS 5/155).
This remedy comes with a limit that surprises most injured people. It belongs to the policyholder. Section 155 applies to an action on a policy, so it is your own insurer you can pursue this way, on an uninsured motorist, underinsured motorist, medical payments, or collision claim. If you are the person the other driver hit, you have no contract with their insurance company, and Illinois does not give a third-party claimant a direct bad-faith or Section 155 action against it. Your leverage there comes from the underlying injury claim and from suing the at-fault driver, which is a different kind of pressure but real pressure all the same.
Why Fault Is Central to the Investigation
A key reason insurers dig into liability is Illinois comparative negligence. Your compensation is reduced by your share of fault, and you are barred from recovering anything if you are found more than 50% at fault (735 ILCS 5/2-1116). Because even a modest shift in blame lowers what the insurer pays, adjusters have a strong incentive to build a case that you were partly, or mostly, responsible. Being careful about what you say early on matters for exactly this reason.
How to Protect Yourself During an Insurance Investigation
You cannot stop an insurer from investigating, but you can keep the process from being turned against you. A few habits make a real difference:
- Document everything, including photos of the scene and damage, the police report, and a list of injuries and expenses
- Be honest and consistent, because contradictions are the fastest way to have a claim reduced or denied
- Get medical care promptly and follow your treatment plan, since gaps in care are used to dispute injuries
- Be cautious with recorded statements, which adjusters use to lock in answers that can later be used against you
- Watch what you post on social media while your claim is open
- Talk to a lawyer before accepting any settlement, especially if the claim keeps sitting “under investigation”
An attorney changes the dynamic. Once you are represented, the insurer has to communicate through your lawyer, follow the rules on timely handling, and justify its decisions, which makes it far harder to run out the clock and pressure you into a low offer. Our Illinois car accident lawyers deal with adjusters and their investigations every day, and we handle injury cases on a contingency fee, so you pay nothing unless we recover money for you.

Frequently Asked Questions
Why would an insurance company investigate my claim?
An insurance company investigates a claim to confirm it is legitimate, verify that the policy covers the loss, determine who was at fault, and value the damages. The review guards against fraud, but it also gives the insurer room to question your injuries and reduce what it pays, which is why documentation and consistency matter.
What does it mean when my claim is “under investigation”?
It usually means the adjuster is reviewing both liability and coverage before deciding whether to pay. It is a normal step, not a denial or an accusation. The main risk for an injured claimant is delay, since a claim that stays under investigation can pressure you into accepting a low settlement.
How long can an insurance company take to investigate a claim in Illinois?
An investigation can take from about a week to several months depending on the claim’s complexity. Illinois law requires insurers to act with reasonable promptness and to conduct a reasonable investigation (215 ILCS 5/154.6). Because you generally have only two years to file an injury lawsuit (735 ILCS 5/13-202), and only one year if a local government vehicle was involved (745 ILCS 10/8-101), a long delay is a reason to seek legal advice rather than keep waiting.
Can I sue the other driver’s insurance company for delaying my claim?
Generally no. Illinois gives the vexatious-delay remedy in 215 ILCS 5/155 to a party to the policy, so it fits a dispute with your own insurer over uninsured motorist, underinsured motorist, medical payments, or collision benefits. As the person the other driver hit, your case is against the driver, and filing that lawsuit is usually what moves their insurer.
Do insurance companies really check your social media?
Yes. Investigators routinely review public social media accounts for posts that contradict a claim, such as photos of physical activity that seem inconsistent with a reported injury. It is smart to limit what you share publicly while a claim is open.
Can I refuse to give a recorded statement to the insurance company?
You are generally not required to give a recorded statement to the other driver’s insurer, and adjusters often use those statements to lock in answers that can later be used to minimize your claim. It is reasonable to decline until you have spoken with a lawyer.
Should I talk to a lawyer if my insurance claim is being investigated?
It often helps, especially if fault is disputed, your injuries are serious, or the claim keeps sitting under investigation. A lawyer can push the insurer to follow Illinois claim-handling rules, protect you from tactics designed to reduce your payout, and take the case to court if the company refuses to treat it fairly.
If an insurance company is investigating your claim and you feel the process is being used to delay or lowball you, you do not have to face the adjuster alone. Contact 844-SEE-MIKE anytime for a free, no-pressure consultation, and you pay nothing unless we recover money for you.
