First-Party vs Third-Party Insurance Claims: Which Appeals Process Applies?

First-Party vs Third-Party Insurance Claims: Understanding the Difference

When your insurance claim is denied, one of the most fundamental questions is: which type of claim is this? Understanding whether you have a first-party or third-party claim dramatically affects your rights, your appeal options, and the legal remedies available to you.

This distinction is not just academic — it determines who you can sue, which regulator you can complain to, how the claim is handled, and what your litigation options are if the claim is wrongly denied.

What Is a First-Party Insurance Claim?

A first-party claim is a claim you make against your own insurance policy. You are the policyholder (the "first party"), and you are claiming benefits from your own insurer (the "second party" — insurance companies technically being the second party in the contract).

Examples of First-Party Claims

• Health insurance: You make a claim to your own health insurer for your own medical treatment
• Homeowners or property insurance: Your home is damaged and you claim against your own homeowners policy
• Comprehensive auto insurance: Your car is damaged and you claim against your own comprehensive auto policy
• Life insurance: Your beneficiary claims against your life insurance policy after your death
• Disability insurance: You claim against your own disability policy when you cannot work
• Critical illness insurance: You claim your own CI policy after a diagnosis
• Travel insurance: You claim against your own travel policy for medical expenses abroad
• Uninsured/underinsured motorist coverage: You were hit by an uninsured driver and claim against your own UM/UIM coverage

Key Characteristics of First-Party Claims

• You are in a direct contractual relationship with the insurer
• The insurer owes you duties based on the insurance contract — including the duty to act in good faith
• Appeal rights flow from the contract and from regulation — you can appeal, complain to regulators, and in some cases sue the insurer for bad faith
• You control the claim process — you can negotiate, appeal, and escalate

What Is a Third-Party Insurance Claim?

A third-party claim is a claim made against someone else's insurance policy. You are a third party (neither the policyholder nor the insurer) claiming that the policyholder's insurance should cover a loss you suffered as a result of the policyholder's actions.

Examples of Third-Party Claims

• Auto liability insurance: You were injured in an accident caused by another driver. You make a claim against their auto liability insurance.
• Homeowners liability: You were injured on someone's property (e.g., slipped on an icy sidewalk). You make a claim against their homeowners liability coverage.
• Business liability insurance: A business's negligence caused you harm. You make a claim against their general liability policy.
• Professional liability (malpractice): A doctor, lawyer, or accountant made a negligent error. You make a claim against their malpractice insurance.
• Workers' compensation (in some jurisdictions): A third-party employer's workers' comp insurer covers your injuries.

Key Characteristics of Third-Party Claims

• You are not in a direct contract with the insurer — the insurer's customer is the policyholder, not you
• The insurer's primary loyalty is to its policyholder, not to you
• Your right to payment comes from the policyholder's liability to you, not from a contract
• Appeal rights are more limited — you cannot always directly access regulatory ombudsman services because you have no direct contract with the insurer
• Litigation is often the ultimate enforcement mechanism — you sue the policyholder (their insurer defends and pays); or in some jurisdictions, you can sue the insurer directly

How the Appeals Process Differs

First-Party Appeal Rights

Because you have a direct contract with your insurer, you have the strongest appeal and dispute rights:

1. Internal appeal to the insurer

• You have the contractual right to dispute a claim decision
• Regulators require defined timelines for appeal responses
• Most jurisdictions require the insurer to explain the reasons for denial in writing

2. Regulatory complaint

• You can file directly with the insurance regulator (FCA in UK, ASIC in Australia, State DOI in USA, IRDAI in India, IRA in Kenya, etc.)
• This is only available for first-party claims because you are the customer of record

3. Ombudsman services

• Most ombudsman and dispute resolution services (FOS, AFCA, OFS, Bima Lokpal, OSTI, FIDReC) are available to first-party claimants
• These services are free and can compel payment

4. Bad faith litigation

• In many jurisdictions, you can sue your own insurer for bad faith — damages beyond the policy value — if they handled your claim unreasonably
• This remedy is ONLY available in first-party claims (you cannot sue someone else's insurer for bad faith; you can only claim damages from them)

Third-Party Appeal Rights

Your rights when dealing with someone else's insurer are more limited:

1. You are not the insurer's customer

• You cannot file an internal appeal with the at-fault party's insurer
• The insurer is managing the claim on behalf of their customer, not on your behalf

2. Regulatory complaints are limited

• Most ombudsman and regulatory complaint services are only available to policyholders — not third-party claimants
• Exception: Some states and jurisdictions allow limited regulatory complaints by third parties

3. Your primary legal recourse is against the policyholder

• If the at-fault party's insurer denies or underpays your claim, you sue the policyholder (the person who caused the harm), not their insurer directly
• The insurer will appear and defend the policyholder, but the legal action is against the at-fault party

4. Direct action statutes (some jurisdictions)

• Some jurisdictions allow third-party claimants to sue the insurer directly in certain circumstances
• USA: Some states have "direct action" statutes allowing direct suits against liability insurers
• UK: Third Parties (Rights Against Insurers) Act 2010 allows third parties to claim against an insolvent policyholder's insurer directly
• Australia: Insurance Contracts Act 1984, Part IV allows third-party rights in some circumstances

Special Cases: When a Claim Is Both

Uninsured/Underinsured Motorist Claims

UM/UIM coverage sits in an interesting middle position. You claim against your own insurer (first-party), but the substantive question is who caused the accident and whether the at-fault driver was uninsured or underinsured. Your own insurer may dispute the at-fault driver's liability in ways that feel like a third-party dispute — but your regulatory rights are first-party because you are their customer.

Workers' Compensation

Depending on jurisdiction:

• First-party aspect: Your employer's workers' comp policy pays for your injuries — you file with the employer's insurer
• Third-party aspect: If a third party (not your employer) caused your workplace injury, you may have both a workers' comp claim AND a third-party liability claim against the at-fault party

Subrogation Claims

When your insurer pays your first-party claim and then pursues the at-fault third party for reimbursement, this is called subrogation. This is a claim between insurers that typically doesn't involve you directly — but understanding it means you know that accepting a third-party liability settlement may affect your first-party recovery in some cases.

Practical Guidance: What to Do in Each Situation

If Your Own Insurance Denied Your Claim

You have the strongest rights here. Use the full sequence:

1. File a formal internal appeal
2. File a regulatory complaint with your national regulator
3. Use the ombudsman service (free)
4. Pursue bad faith litigation if applicable

If Someone Else's Insurance Is Denying or Underpaying Your Claim

Your options are different:

1. Negotiate directly with the at-fault party's insurer (get everything in writing)
2. Get an independent assessment of your damages (property damage estimates, medical bills, income loss)
3. If negotiations fail, consult a personal injury or civil litigation attorney
4. File suit against the at-fault policyholder (their insurer defends and pays)
5. Check whether your jurisdiction has a direct action statute allowing you to sue the insurer

Critical: Never accept a third-party settlement without understanding the full extent of your damages. Property damage is easy to value, but personal injury claims may have long-term consequences that aren't yet apparent.

Common Mistakes

1. Thinking you can use the ombudsman for a third-party dispute. Ombudsman services are almost universally limited to first-party disputes. A third-party claimant cannot typically use AFCA, FOS, or similar services against someone else's insurer.

2. Filing a regulatory complaint for a third-party denial. This generally won't be accepted. Your recourse is through litigation against the at-fault party.

3. Not using your own insurance when you should. If you have applicable first-party coverage (UM/UIM, collision, health), using your own coverage first may be faster than pursuing the at-fault party's insurer — and your own insurer can subrogate to recover from the at-fault party.

4. Signing a third-party settlement release prematurely. Once you sign a release with a third-party insurer, you typically cannot make further claims. Ensure your damages are fully known before signing.
