Facing an insurance claim denial can feel like a betrayal. You pay premiums expecting support, not a battle. But what happens when your insurer acts in bad faith insurance? In 2025, proving bad faith requires a strategic approach that understands both traditional tactics and emerging challenges.

Bad faith insurance refers to dishonest or unfair practices by an insurance company. This could include unjustly denying a valid claim, unreasonably delaying claim processing, or failing to conduct a thorough investigation.

As we discussed in our main guide, understanding bad faith is the first step. This post delves into proving it and focuses on strategies relevant in 2025, given the rise of AI and data-driven claims processing. You can read more about the basics of bad faith in the “Bad Faith Insurance Practices: Recognizing and Responding” section of our main guide, “Navigating the Insurance Claims Process: Your Rights, Recourse, and Roadmap to a Fair Settlement.”

This post will provide a step-by-step guide to building a winning case, including gathering evidence, understanding current trends like AI-driven denials and data privacy issues, and exploring available legal recourse.

Proving how to prove bad faith insurance claim can be complex, and it is advisable to seek legal counsel.

Understanding the Foundation: What Constitutes Bad Faith?

Understanding what bad faith insurance is is the first critical step. It goes beyond simply disagreeing with the insurance company’s decision. It involves a breach of the insurer’s duty of good faith and fair dealing. Every insurance policy carries an implied covenant that both the insurer and the insured will act honestly and fairly towards each other, regardless of the specific wording in the contract.

Here are some examples of insurance claim denial conduct that may constitute bad faith:

  • Unreasonable denial of a claim: This is when the insurer denies a claim without a reasonable basis. For instance, if the damage clearly falls under the policy’s coverage and there’s no valid reason to deny it, the denial could be considered bad faith.
  • Unreasonable delay in processing a claim: Insurers must process claims in a timely manner. Dragging their feet, constantly requesting more information without justification, or failing to communicate updates can all be signs of bad faith.
  • Failure to properly investigate a claim: An insurer has a responsibility to conduct a thorough and impartial investigation of a claim. This means gathering all relevant information, interviewing witnesses, and consulting with experts if necessary. A superficial or biased investigation can be evidence of bad faith.
  • Misrepresenting policy language: Sometimes, insurers will try to twist the meaning of the policy to deny or reduce a claim. This could involve selectively quoting policy language, ignoring relevant provisions, or interpreting ambiguous language in their favor.
  • Offering an inadequate settlement: Even if the insurer acknowledges coverage, they may offer a settlement that is far less than the actual value of the loss. This can be considered bad faith if the insurer is deliberately trying to lowball the claimant.
  • Failing to communicate effectively with the policyholder: Insurers have a duty to keep policyholders informed about the status of their claim and to respond to their inquiries in a timely manner. Ignoring phone calls, failing to provide updates, or being evasive can be signs of bad faith.

It’s crucial to understand that “bad faith” is often fact-specific and depends heavily on the specific circumstances of the case and the laws of the jurisdiction where the claim is filed. What might be considered bad faith in one state may not be in another.

For a more in-depth overview of what constitutes bad faith, you can refer back to the pillar post on “Bad Faith Insurance Practices.” This will give you a solid foundation before we delve into the specifics of proving it.


## Step 1: Deep Dive into Evidence Gathering

Proving bad faith requires a strong and well-documented case. It’s not enough to simply allege that the insurer acted unfairly; you need to present concrete evidence to support your claim. This section will guide you through the essential steps of gathering that evidence. A thorough insurance claim investigation is critical to uncovering the facts necessary to support a bad faith claim.


### Internal Insurance Company Documents

One of the most valuable sources of evidence for proving bad faith is the insurer’s own internal documents. These documents can reveal the insurer’s thought process, their evaluation of the claim, and any potential biases or improper motives.

Discovery rules vary by jurisdiction, but generally, claimants can request a wide range of insurance company documents, including:

  • Emails and other communications between adjusters, supervisors, and other employees involved in the claim.
  • Claim handling manuals and training materials that outline the insurer’s policies and procedures.
  • Adjuster notes and internal memoranda documenting their investigation and assessment of the claim.
  • Reinsurance agreements that may influence the insurer’s decision-making.

Insurers are increasingly using digital platforms for communication and documentation, making e-discovery insurance tools essential. This means you may need to request electronic data, such as emails, text messages, and data stored in claim management systems.

Courts are becoming stricter on insurers’ obligations to preserve and produce electronic evidence. Insurers have a duty to take reasonable steps to prevent the spoliation (destruction or alteration) of evidence. Failure to do so can result in sanctions, such as adverse inferences or even dismissal of the insurer’s defenses. The Sedona Conference provides valuable resources on e-discovery best practices.

Some states have specific regulations about the types of documentation insurers must maintain and make available to policyholders during claim investigations. Knowing these regulations can give you a significant advantage in obtaining the information you need. Consulting with an attorney can help you navigate these regulations and ensure you are requesting all the necessary documents.


### Expert Witness Testimony

Expert witness insurance testimony can be a vital component of a insurance claim investigation, especially in complex bad faith cases. Insurance policies and claim handling practices can be difficult for a jury to understand, and an expert witness can help translate complex terminology and procedures into plain language.

An expert witness can provide opinions on a variety of issues, including:

  • Whether the insurer’s conduct deviated from industry standards.
  • Whether the insurer’s investigation was reasonable and thorough.
  • Whether the insurer’s denial of the claim was justified based on the policy language and the facts of the case.
  • The value of the claim and whether the insurer’s settlement offer was adequate.

Common choices for expert witnesses include former insurance adjusters, claims managers, and insurance law professors. The key is to find an expert who has extensive experience and knowledge in the relevant area of insurance.

The Daubert Standard (federal) and similar state standards govern the admissibility of expert testimony, focusing on the expert’s qualifications, methodology, and the reliability of their opinions. It’s crucial to ensure that your expert meets these standards; otherwise, their testimony may be excluded from evidence. Cornell Law School provides a comprehensive explanation of the Daubert Standard.

It’s crucial to vet experts carefully and ensure their reports are well-reasoned and supported by evidence. A poorly prepared expert can do more harm than good to your case.


### Documenting Emotional Distress

Many jurisdictions allow recovery for emotional distress damages in bad faith cases. This recognizes that the insurer’s wrongful conduct can cause significant emotional harm to the policyholder, beyond just the financial loss of the denied claim. Understanding what evidence is needed for emotional distress in bad faith claim is key.

Documenting emotional distress can include a range of symptoms, such as:

  • Anxiety
  • Depression
  • Sleep disturbances
  • Stress-related physical ailments (e.g., headaches, stomach problems)
  • Loss of enjoyment of life

Evidence that can be used to document emotional distress includes:

  • Medical records and therapist notes documenting the claimant’s psychological symptoms and treatment.
  • Personal journals or diaries describing the claimant’s feelings and experiences.
  • Testimony from family and friends who can attest to the claimant’s emotional state.
  • Expert testimony from psychologists or psychiatrists who can provide a professional assessment of the claimant’s emotional distress.

The key is to establish a clear causal link between the insurer’s bad faith conduct and the claimant’s emotional distress. You need to show that the insurer’s actions directly caused or exacerbated the claimant’s emotional suffering.


### Demonstrating a Pattern of Behavior

In some cases, proving bad faith can be strengthened by showing that the insurer has a history of similar bad faith conduct. This can suggest that the insurer’s actions in your case were not an isolated incident but rather part of a broader pattern of unfair claims handling practices.

However, this information is very difficult to obtain due to privacy concerns and the insurer’s efforts to keep such information confidential. Insurers are very protective of their internal claims data and will often fight vigorously to prevent its disclosure.

Potential sources of information about an insurer’s past conduct include:

  • Publicly available court records of lawsuits filed against the insurer alleging bad faith.
  • Regulatory actions by state insurance departments, such as fines, suspensions, or other disciplinary measures.

The National Association of Insurance Commissioners (NAIC) website may provide some information on regulatory actions, although access may be limited.

Some states may allow discovery of similar claims handling practices in other cases, but this is often subject to strict limitations. Courts are often reluctant to allow discovery of this type of information unless there is a strong showing that the insurer’s conduct in other cases is substantially similar to the conduct in your case.


## Step 2: Recognizing and Addressing Unreasonable Delay

An unreasonable delay in handling a claim can be a form of bad faith in itself, or it can be an indicator of other bad faith tactics. Insurers have a duty to process claims promptly and efficiently. They cannot simply sit on a claim without taking action.

What constitutes an “unreasonable delay” is fact-specific and depends on the complexity of the claim, the insurer’s workload, and applicable state laws. There is no one-size-fits-all definition.

Factors that courts consider when determining whether a delay was unreasonable include:

  • The length of the delay.
  • The complexity of the claim and the amount of investigation required.
  • The insurer’s workload and staffing levels.
  • The reason for the delay.
  • The insurer’s communication with the claimant.

Examples of conduct that may constitute unreasonable delay include:

  • Failing to promptly investigate a claim.
  • Delaying communication with the claimant.
  • Requesting unnecessary documentation or information.
  • Failing to provide a reasonable explanation for the delay.
  • Repeatedly changing adjusters assigned to the claim.
  • Failing to make a decision on the claim within a reasonable time.

Many states have insurance regulations that define “promptness” requirements for claims handling. These regulations may specify timeframes for acknowledging receipt of a claim, conducting an investigation, and making a decision.

Case law in your jurisdiction may also provide precedent on what constitutes a reasonable timeframe for different types of claims. Courts have often addressed the issue of unreasonable delay in specific contexts, such as property damage claims, auto accident claims, and disability claims.


## Step 3: Navigating the New Landscape: Key Trends in 2025 and Beyond

The insurance landscape is constantly evolving, and in 2025, certain trends are significantly impacting bad faith insurance claims. These trends present both new challenges and new opportunities for policyholders seeking to hold insurers accountable.


### Trend 1: The Rise of AI-Driven Denials and Bad Faith

As Artificial Intelligence (AI) becomes more prevalent in claims processing, it’s crucial to explore scenarios where AI algorithms contribute to AI insurance denial and potentially lead to bad faith. The increasing reliance on AI in insurance raises important questions about transparency, fairness, and accountability.


#### Algorithmic Bias in Claims Processing: How AI Can Lead to Unfair Denials

AI algorithms are trained on data, and if that data reflects existing biases (e.g., based on demographics, location, or socioeconomic status), the algorithm may perpetuate those algorithmic bias insurance in claim decisions. This can lead to unfair denials for certain groups of policyholders.

For example, if an AI algorithm is trained primarily on data from wealthier neighborhoods, it may be more likely to approve claims from those areas while denying similar claims from lower-income neighborhoods. This type of bias can be difficult to detect but can have a significant impact on the fairness of claims handling.

Algorithmic transparency is a key issue, as it’s often difficult to understand how an AI algorithm arrived at a particular decision. Insurers may claim that the algorithm is a “black box” and that they cannot explain the reasoning behind its decisions. However, this lack of transparency makes it difficult to challenge unfair denials and hold insurers accountable.

The Equal Employment Opportunity Commission (EEOC) and the Anti-Defamation League (ADL) provide resources and information on algorithmic bias and its potential impact on various sectors.


#### Demanding Transparency: Challenging AI-Driven Claim Decisions

Claimants should demand detailed explanations of how AI algorithms were used in their claim decisions. This includes asking for the specific data points that the algorithm considered and the reasoning behind the decision. Understanding challenging AI claim decisions starts with transparency.

Insurers may resist providing this information, citing trade secrets or proprietary information. However, claimants can argue that they are entitled to this information to understand and challenge the decision. They can argue that the insurer has a duty to provide a reasonable explanation for the denial and that withholding information about the AI algorithm prevents them from doing so.

DARPA is working on Explainable AI (XAI) techniques that could make AI decision-making more transparent and understandable. However, these techniques are still in their early stages of development and are not yet widely used in the insurance industry.


#### Legal Recourse for AI-Related Bad Faith Claims

Proving AI insurance denial can be challenging because it’s difficult to understand the decision-making process. However, legal strategies may include:

  • Arguing that the insurer failed to adequately supervise the AI algorithm.
  • Arguing that the algorithm was biased.
  • Arguing that the insurer failed to conduct a reasonable investigation of the claim, even if the AI algorithm recommended denial.

In some cases, it may be possible to obtain information about the AI algorithm’s training data and code through discovery. This can help to uncover biases or other flaws in the algorithm.


### Trend 2: Increased Scrutiny of Data Privacy and Use in Claims

Insurers collect vast amounts of personal data during the claims process, including medical records, financial information, and social media activity. The increasing scrutiny of data privacy insurance and how insurers use this data raises important ethical and legal concerns.


#### Data Privacy Violations as Evidence of Bad Faith

Misusing this data, such as sharing it with unauthorized third parties or using it for purposes unrelated to the claim, can be a violation of privacy laws and may be evidence of bad faith. Protecting data privacy insurance is becoming increasingly important.

For example, if an insurer shares a claimant’s medical records with their employer without their consent, this could be a violation of HIPAA (the Health Insurance Portability and Accountability Act) and could also be evidence of bad faith.

The California Consumer Privacy Act (CCPA) and HIPAA provide individuals with rights regarding their personal data, including the right to access, correct, and delete their data. Violations of these laws can give rise to legal claims and may also be used as evidence of bad faith.


#### The Use of Social Media and Surveillance in Insurance Claims: Ethical and Legal Boundaries

Insurers increasingly use social media and other surveillance methods to investigate claims. Understanding whether can insurance companies use social media to deny claims is crucial. This raises ethical and legal concerns about privacy and whether insurers are overstepping their bounds.

Courts have generally held that information publicly available on social media can be used in claims investigations. However, using deception to gain access to private social media accounts or engaging in excessive surveillance may be considered an invasion of privacy and evidence of bad faith. If an insurer creates a fake social media profile to “friend” a claimant and gain access to their private information, this could be considered an unethical and potentially illegal practice.

Claimants should be aware of their privacy settings on social media and take steps to protect their personal information. They should also be cautious about what they post online, as it could be used against them in a claim investigation. In these modern times, it is important to be mindful of social media insurance investigation.


### Trend 3: The Impact of Climate Change on Bad Faith Claims (Property Insurance)

With increasing frequency of extreme weather events, insurers may try to deny or underpay claims by citing policy exclusions or blaming damage on pre-existing conditions. This trend is particularly relevant to property insurance claims and highlights the growing impact of climate change insurance claims.


#### Navigating Bad Faith Claims After Natural Disasters: Hurricane, Wildfire, Flood

After major natural disasters, insurers may be overwhelmed with claims and may resort to tactics such as denying or underpaying claims, delaying investigations, or misinterpreting policy language to limit their liability. In the wake of any natural disaster insurance claims, policyholders need to be especially vigilant.

For example, after a hurricane, an insurer may deny claims for wind damage by arguing that the damage was actually caused by flooding, which is often excluded from coverage. Or, they may delay the investigation of claims due to the high volume of claims, leaving policyholders without the funds they need to repair their homes.

FEMA and the Consumer Federation of America provide resources and information for policyholders navigating insurance claims after natural disasters.


#### Proving Causation: When Insurers Blame ‘Pre-Existing Conditions’ After a Disaster

Insurers may try to deny claims by arguing that damage was caused by pre-existing condition insurance denial rather than the covered event (e.g., a hurricane). For example, an insurer may argue that roof damage was caused by long-term wear and tear rather than the hurricane winds.

Policyholders need to provide evidence that the damage was directly caused by the covered event. This may include photographs, videos, expert testimony from engineers or contractors, and weather reports.

Expert testimony from engineers or contractors can be valuable in establishing causation. They can inspect the property and provide an opinion on the cause of the damage, based on their professional expertise.


## Case Studies: Bringing it All Together

These case studies illustrate how these concepts apply in real-world scenarios. These anonymized case studies (or hypothetical scenarios based on real cases) illustrate different types of bad faith and how to prove them.


### The AI Denial Case

A homeowner’s claim for roof damage after a hailstorm was denied based on an AI algorithm that determined the damage was pre-existing wear and tear.

The homeowner, suspecting bias in the algorithm, demanded transparency from the insurer. The insurer refused.

The homeowner filed suit alleging bad faith, arguing the insurer failed to properly investigate the claim and relied on a biased AI algorithm.

Through discovery, the homeowner obtained information about the algorithm’s training data and found evidence of bias against homes in older neighborhoods. The algorithm was more likely to classify damage to older roofs as pre-existing wear and tear, even if the damage was actually caused by the hailstorm.

This case highlights the challenges and strategies for challenging AI-driven bad faith denials. It demonstrates the importance of demanding transparency, investigating the AI algorithm’s training data, and presenting evidence of bias.


## Conclusion

Proving bad faith insurance practices requires a strategic and proactive approach. By understanding what constitutes bad faith, meticulously gathering evidence, and staying informed about emerging trends, policyholders can significantly increase their chances of success.

Remember the key steps:

  • Gather all relevant documentation, including the insurance policy, claim correspondence, and any other evidence supporting your claim.
  • Request internal documents from the insurance company to understand their claims handling process and decision-making.
  • Document any emotional distress caused by the insurer’s wrongful conduct.
  • Consider consulting with expert witnesses to provide opinions on industry standards and the reasonableness of the insurer’s actions.
  • Be aware of the evolving landscape of insurance, including the increasing use of AI and data analytics, and the impact of climate change.

Proving bad faith insurance can be challenging, but with a strategic approach and a thorough understanding of your rights, you can hold insurers accountable and obtain the fair settlement you deserve. Seeking legal counsel from an experienced attorney is always advisable to navigate the complexities of bad faith claims.
