What Is an Insurance Adjuster — and What Do They Do After an Accident?

When you file a claim after a car accident, one of the first people you'll hear from is an insurance adjuster. Understanding what they do — and whose interests they represent — is one of the most useful things you can know before that first phone call.

The Basic Role: Investigate, Evaluate, Settle

An insurance adjuster is an employee or contractor hired by an insurance company to handle claims. Their core job is to:

• Investigate what happened in the accident
• Evaluate the damage to vehicles, property, and sometimes physical injuries
• Determine what the insurance policy covers and to what extent
• Negotiate and settle the claim within the limits of that coverage

Adjusters aren't neutral third parties. They work for the insurance company — either as staff employees or as independent contractors hired on a per-claim basis. Their job is to resolve claims fairly within the terms of the policy, but also to protect the insurer's financial exposure.

First-Party vs. Third-Party Adjusters

The type of adjuster you're dealing with depends on whose insurance company is handling the claim.

In a first-party claim, you're working with your own insurance company — for example, using your collision coverage after an accident, or making a claim under your uninsured motorist (UM) coverage. In a third-party claim, you're dealing with someone else's insurer, which creates a different dynamic: that adjuster's primary obligation runs to their policyholder, not to you.

What Adjusters Actually Investigate 🔍

After a claim is opened, the adjuster typically begins gathering information to build a picture of what happened and what the damages are worth. This usually includes:

• The police report, if one was filed
• Photos and video of vehicle damage and the accident scene
• Statements from the drivers and any witnesses
• Medical records and bills, particularly in injury claims
• Repair estimates from body shops or their own appraisers
• Documentation of lost wages, if wage loss is being claimed

In injury claims, the adjuster may also request access to your medical records — sometimes well beyond what's directly related to the accident. How much access they're entitled to depends on the claim type, your state's laws, and what you've signed.

How Adjusters Determine Fault and Value

In at-fault states, the adjuster's investigation is partly aimed at establishing liability — who was responsible for the crash, and by what percentage. In states that follow comparative negligence rules, fault can be split between parties, which affects how much compensation each side can recover. In the small number of states using contributory negligence, being even partially at fault can significantly affect a claim's outcome.

In no-fault states, the fault question is less central for basic injury claims — each driver's own insurer pays certain medical expenses and lost wages regardless of who caused the crash, up to policy limits. But fault still matters for property damage and for claims that exceed the no-fault threshold.

Once liability is assessed, adjusters calculate the value of the claim — what the policy covers and what they're willing to offer. For property damage, this typically involves repair costs or actual cash value if a vehicle is totaled. For injury claims, the calculation is more complex, factoring in medical bills, future treatment costs, lost income, and pain and suffering, all of which are harder to quantify and more likely to be disputed.

The Settlement Offer Process

An adjuster's first offer is rarely their final one. Claimants — especially in injury claims — often submit a demand letter laying out their damages and the amount they're seeking. The adjuster responds, negotiation follows, and a settlement is either reached or the claim moves into dispute.

How much leverage either side has depends on factors like:

• The strength of the liability evidence (is fault clear or disputed?)
• The severity and documentation of injuries
• Policy limits on both sides
• Whether the claimant has legal representation — adjusters typically handle represented claimants differently than unrepresented ones
• State law, including tort thresholds, damage caps, and procedural rules

Special Adjusters for Complex Claims

Not all adjusters handle every type of claim. Some insurers use desk adjusters who work remotely, field adjusters who inspect vehicles or accident scenes in person, and independent adjusters who are brought in during high-volume periods or for specialized claims. In serious injury cases, claims may be escalated to more senior adjusters or to a special investigations unit if fraud is suspected.

What Shapes Your Experience With an Adjuster

No two claims unfold the same way. The adjuster's role — and how that interaction goes — is shaped by:

• Your state's fault and no-fault rules
• The type of coverage in play (liability, PIP, MedPay, UM/UIM, collision)
• The nature and severity of injuries
• Whether liability is clear or contested
• Whether you have an attorney
• The specific policy language on both sides

An adjuster reviewing a clear rear-end fender-bender in a no-fault state is doing a very different job than one handling a disputed multi-vehicle crash with serious injuries in a comparative fault state.

Your state, your policy, and the specific facts of your accident determine how any of this actually applies to your situation — and those details aren't something any general explanation can substitute for.
