San Francisco, CA Guide to First-Party and Third-Party Insurance Bad Faith

Insurance bad faith can mean different things depending on whose losses are being handled and whose rights the insurer owes a duty to protect. The basic distinction is whether the claim is made by the policyholder under their own coverage or by someone seeking payment because the policyholder may be legally responsible for an injury or damage.

For residents, renters, drivers, homeowners, and small property owners in San Francisco, understanding that difference can make claim communications easier to evaluate and help clarify what an insurer is actually required to do.

What is a first-party insurance claim?

A first-party claim is made by a policyholder seeking benefits directly from their own insurance policy. The loss usually involves the policyholder, an insured household member, or covered property.

Common examples include:

• A homeowner seeking payment for covered water, fire, smoke, or storm damage
• A renter seeking payment for damaged personal belongings
• A driver filing a collision or comprehensive claim under their own auto policy
• A person making an uninsured or underinsured motorist claim
• A business owner seeking coverage for damage, theft, or interruption of operations

In a first-party claim, the insurer has a contractual relationship with the policyholder. The company must evaluate the claim fairly, investigate relevant facts, explain its coverage position, and pay benefits that are owed under the policy.

A disagreement does not automatically establish bad faith. An insurer may reasonably deny a claim because of an exclusion, lack of proof, a coverage limit, or a genuine dispute about the cause of loss. Bad faith generally involves more than an incorrect decision. The issue is often whether the insurer acted unreasonably or without proper cause in investigating, delaying, denying, or underpaying the claim.

What is a third-party insurance claim?

A third-party claim involves a person who is not the policyholder but is seeking compensation because the policyholder may have caused injury or property damage.

Examples include:

• A pedestrian injured in a collision involving an insured driver
• A visitor who claims to have been injured on an insured property
• A neighboring property owner whose building or belongings were allegedly damaged
• A driver seeking payment from another driver’s liability insurer

The insurer’s primary contractual duties in this setting generally run to its insured, not directly to the injured claimant. The insurer may investigate the claim, communicate with the claimant, negotiate a settlement, or defend the insured in a lawsuit.

That difference matters. A third-party claimant is not usually entitled to treat the other person’s insurer as if it were the claimant’s own insurance company.

How does first-party bad faith usually arise?

First-party bad faith often concerns the handling of benefits owed directly to the policyholder. Possible warning signs may include:

• Delays that are not adequately explained
• Failure to investigate important evidence
• Relying only on facts that support denial while ignoring contrary information
• Misrepresenting policy language or available benefits
• Repeatedly requesting unnecessary documents
• Offering substantially less than the evidence supports without a reasonable explanation
• Denying a claim without identifying the relevant policy provision
• Failing to reassess a decision after receiving significant new information

California claim-handling rules generally require insurers to acknowledge communications, investigate claims fairly, explain certain decisions, and provide timely responses. For many first-party claims, a written denial should identify the legal or policy basis for the decision.

A delay can be especially disruptive after a major property loss. In dense housing, a leak, electrical problem, smoke condition, or structural issue can affect neighboring units and create temporary housing, storage, repair, and access problems. Those practical consequences do not by themselves prove bad faith, but they can make clear communication and accurate claim records especially important.

How does third-party bad faith differ?

Third-party bad faith most often involves an insurer’s handling of a liability claim against its insured. The central concern is whether the insurer unreasonably failed to protect the insured from personal exposure beyond the policy limits.

For example, suppose a driver causes a serious collision and the injured person makes a reasonable settlement demand within the available liability limits. If the insurer unreasonably refuses to settle and the matter later produces a judgment exceeding the policy limits, the insured may face financial exposure that could potentially have been avoided.
The duty at issue is commonly described as the insurer’s duty to accept a reasonable settlement when liability and damages are sufficiently clear. The insurer must consider the insured’s interests, not simply its own desire to minimize payment or continue litigating.
A third-party claimant may provide information, medical records, repair documentation, or a settlement demand. However, the claimant generally does not have the same direct bad-faith rights as the policyholder. California law usually treats the insurer’s settlement duty as one owed to the insured. In some circumstances, rights may later be assigned or become enforceable after a judgment, but those issues are fact-specific.

Can a third-party claimant sue an insurer for bad faith?

Usually, not in the same way that a policyholder can. A third-party claimant generally lacks a direct contractual relationship with the other person’s insurer.
The claimant may still have legal rights against the person or business responsible for the injury or damage. The claimant may also have rights under specific statutes, court procedures, or an insurance policy that expressly benefits certain people. A judgment, assignment, or other unusual circumstance can change the analysis.
This is one reason a claimant should avoid assuming that an insurer’s delay or low settlement offer automatically creates a direct bad-faith lawsuit against the insurer. The legal theory, timing, and available remedies can differ substantially from a first-party dispute.

Is a denied claim automatically bad faith?

No. A denial may be wrong without being made in bad faith. Courts generally examine whether the insurer had a reasonable basis for its position and whether the investigation was thorough and evenhanded based on the information available at the time.
A policyholder may have a contract dispute, appraisal dispute, valuation disagreement, or coverage question without having a separate bad-faith claim. Conversely, a claim may involve bad faith even when the insurer eventually pays, particularly if unreasonable delay or improper handling caused additional harm.
The complete claim file matters. Keep copies of:

• The policy and declarations page
• Claim notices and confirmation numbers
• Letters, emails, and text messages
• Photos, videos, estimates, invoices, and receipts
• Medical or repair records
• Notes identifying dates, speakers, and promises made
• Written explanations for delays, denials, or changes in position

What should San Francisco residents watch for?

Local conditions can complicate insurance claims. Older buildings, shared walls, multi-unit ownership, underground utilities, hillside drainage, limited parking, and dense construction can create questions about responsibility and the source of damage.
A single water event, for example, may involve a unit owner’s policy, a building policy, a renter’s policy, and a liability claim against another person. A vehicle collision may involve collision coverage, liability coverage, uninsured motorist benefits, medical payments, and subrogation.
The most useful first step is to identify whose policy is being used, who suffered the loss, and what type of coverage is being requested. That classification often reveals whether the dispute is primarily first-party, third-party, or a combination of both.
