When you’ve been hurt in a car crash caused by someone else, you naturally expect the other driver’s insurance to cover your damages. But what happens when that driver’s policy falls short? That’s when underinsured motorist coverage becomes crucial.
Unfortunately, insurance companies don’t always make accessing that coverage easy. Some are even selling policies that don’t comply with California law. Below, we’ll break down what underinsured motorist coverage is, how it works in California, and what you can do if your claim is denied or delayed.
What Is Underinsured Motorist Coverage?
Underinsured motorist (UIM) coverage is a type of auto insurance that protects you when you’re injured in a crash caused by someone who doesn’t have enough insurance to cover your losses. It’s often bundled with uninsured motorist (UM) coverage, which applies when the at-fault driver has no insurance at all. UIM steps in only after the at-fault driver’s liability policy has been exhausted and only if your damages exceed their coverage limits.
For example, suppose you suffer $100,000 in damages due to a crash, but the at-fault driver only carries the California minimum liability coverage of $15,000. If you have $100,000 in UIM coverage, your insurer may be required to pay up to $85,000 to cover the difference.
Is Underinsured Motorist Coverage Required in California?
California does not require drivers to carry UIM coverage, but insurance companies are required by law to offer it. If you decide not to purchase it, you must decline in writing. Absent a signed waiver, the coverage is automatically added to your auto policy. Many people don’t even realize they have UIM coverage until they’re in a serious crash and start reviewing their declarations page. Others may not realize they declined it years ago to save a small amount on their premium, only to discover too late how vital it is.
If you’re not sure whether you have UIM coverage, ask your insurer for a copy of your declarations page and policy. The time to find out is before a crash, not after.
When Can You Use Underinsured Motorist Coverage?
You can use UIM coverage when several conditions are met:
- The other driver caused the accident.
- The other driver has auto insurance, but not enough to cover your damages.
- You have UIM coverage through your own auto insurance policy.
- You have exhausted the at-fault driver’s liability policy before pursuing your UIM claim.
This process typically involves the other driver’s insurance first “tendering” the full amount of its limit, and then pursuing a claim for the balance through your own insurer. Importantly, you may need your insurer’s written permission before accepting the other driver’s settlement, or you risk jeopardizing your UIM claim.
Common Situations Where UIM Coverage Makes a Big Difference
Many drivers assume underinsured motorist coverage only comes into play after catastrophic accidents, but even so-called “minor” collisions can result in overwhelming expenses. A one-second impact can lead to months or years of physical therapy, surgical recovery, missed work, and financial strain. Between ambulance rides, emergency room visits, MRIs, lost wages, and the cost of future care, damages can quickly exceed the limits of the at-fault driver’s insurance policy.
Consider the following scenarios:
In one common case, the at-fault driver carries California’s minimum required liability coverage: just $15,000 per person. But if you suffer a fractured bone, torn ligaments, or a concussion that leads to extended treatment or time off work, your total losses could reach $75,000 or more. Once the other driver’s insurer pays their $15,000, the remaining $60,000 is your responsibility, unless you have UIM coverage.
In another situation, multiple people are injured in the same accident. Say three passengers are hurt. Regardless of the number of claimants, in order to make a UIM claim, you would need to have a limit greater than the per-person limit of the at-fault party. So, in this hypothetical, (assuming a blanket $30k/ax limit), in order to get UIM, the insured would have to have more than $30k coverage, even if they did not recover that much from the third party. If the third party had a $15k/$30k policy, then the insured would have to have more than $15k of UIM in order to collect anything, even if they did not collect $15k from the at-fault party.
Pedestrians and cyclists are especially vulnerable (yes, UIM coverage covers you even when you are not in a car). A person walking or biking has little protection when struck by a vehicle, even at low speeds. Injuries often include head trauma, spinal injuries, or broken bones, with costs that far exceed what many drivers can cover. If the driver only has minimal insurance (or none at all) your own UIM coverage may be the only source of meaningful compensation.
In all of these situations, underinsured motorist coverage is not just helpful; it can be the difference between financial stability and lifelong debt.
Why UIM Claims Are Often Denied or Delayed
Underinsured motorist coverage is part of your own auto insurance policy. That leads many drivers to assume the claims process will be straightforward. After all, you’ve paid your premiums! But in practice, insurance companies often treat UIM claims with the same skepticism and resistance as claims against you by third-parties. Their goal isn’t to protect your interests; it’s to protect their bottom line.
Insurers use a variety of tactics to avoid or reduce UIM payouts. One common approach is to argue that your total damages don’t actually exceed the at-fault driver’s policy limits. Even when your bills clearly surpass those limits, they may claim some treatments were unnecessary or unrelated to the accident.
They may also minimize the severity of your injuries. This can include suggesting that soft tissue damage or lingering pain isn’t medically serious, or that you waited too long to seek treatment, implying your condition must not be as bad as claimed.
Another strategy involves disputing fault or causation. Even when liability is clear, your insurer might claim you were partially to blame for the crash or that some of your symptoms stem from a preexisting condition.
In some cases, they’ll use the language of your policy against you. They may misinterpret coverage provisions, apply offsets incorrectly, or argue that you didn’t meet certain procedural requirements. These technicalities can be used to justify claim denials or stall negotiations.
Most frustrating of all, some policyholders find that their insurer simply delays responding, fails to investigate promptly, or offers a settlement far below what the claim is worth, banking on the fact that you’re in pain, short on money, and unlikely to fight back.
It’s important to remember: just because the claim is with your insurance company doesn’t mean they’re on your side. UIM claims are adversarial by nature, and insurers often behave no differently than they would if you were a total stranger. This is why having a legal advocate is so critical. An experienced attorney can counter these delay tactics, challenge improper denials, and ensure your claim is taken seriously.
A Deeper Problem: Policies That Don’t Comply With California Law
Denial tactics are frustrating. But there’s a more troubling issue that doesn’t get nearly enough attention: some insurers are selling UIM policies that don’t actually conform to California law.
Attorney Demián Oksenendler has identified this as a growing and largely hidden problem, one he’s actively working to expose and correct. “I’m seeing more and more insurance policies that actually don’t conform to California law,” he explains. “If somebody’s got a UM or UIM claim that’s been denied, really for any reason, I want to hear about it.”
This isn’t limited to small or obscure insurers. Oksenendler has encountered non-compliant policies across major and minor carriers alike, and not only in individual consumer policies. Nonprofits, small businesses, large corporations with many employees and sophisticated brokers have all been sold policies that don’t meet state requirements, often without anyone in the company realizing it. Even churches have fallen victim to this disturbing trend.
In multiple cases, Oksenendler has established proof of this non-compliance and secured favorable resolutions for his clients. Insurers have been willing to resolve those cases quietly rather than have the issue become part of the public record.
What this means for you: if your UIM claim has been denied, the problem may run deeper than a routine dispute over damages. The policy itself may not hold up under California law. That’s a different kind of legal problem, and it requires an attorney who knows where to look.
Steps to Take After a Crash Involving an Underinsured Driver
After any car accident, emotions run high and decisions must be made quickly. But if the at-fault driver is underinsured, the steps you take immediately after the crash can have a lasting impact on your ability to recover compensation through your own underinsured motorist (UIM) coverage. Here’s a practical checklist to help preserve your rights and build a strong claim:
- Seek immediate medical attention. Even if you feel okay at the scene, some injuries, like whiplash, concussions, or internal damage, may not show symptoms until hours or days later. Getting prompt medical care creates an official record and helps prove your injuries are connected directly to the crash.
- Request a copy of the police report. This document is a critical piece of evidence. It contains details about the accident, statements from both drivers, witness information, and often includes the officer’s assessment of who was at fault.
- Get the at-fault driver’s insurance information. You’ll need their policy details to determine whether they’re underinsured and to confirm how much liability coverage is available.
- Notify your insurer as soon as possible. Let your insurance company know that you were involved in a collision and that the at-fault driver may be underinsured. Ask them to verify whether your policy includes UIM coverage and what steps they require for filing a claim.
- Do not accept or sign any third-party settlement without guidance. This is a critical mistake that can ruin your UIM claim. In most cases, you must obtain your insurer’s written permission before accepting a settlement from the other driver’s insurer. Failing to do so may violate the terms of your policy and eliminate your right to seek UIM benefits.
Taking these steps early creates a solid foundation for your case and reduces the chances of costly mistakes. And if the insurance process becomes overwhelming or adversarial, you don’t have to face it alone.
What to Do If Your Underinsured Motorist Claim Is Denied
Receiving a denial letter from your insurance company can be discouraging, but it’s not the end of the road. Many valid UIM claims are initially denied due to technicalities, misinterpretations, or unjustified skepticism. There are clear steps you can take to challenge the decision and assert your rights.
Start by requesting a written explanation for the denial. Insurance companies are legally required to explain why they’re rejecting a claim. This response can reveal whether they believe your damages don’t exceed the third-party policy, or if they’re disputing the connection between the accident and your injuries.
Next, gather all relevant documentation. This includes your medical records, treatment plans, itemized bills, proof of missed work, and any photos or reports related to the crash. This evidence will be essential in disputing the insurer’s findings.
Document all communication with your insurer. Keep records of every call, email, and letter. If a representative promises to “review and call you back,” note the date and time. These records may prove valuable if the claim progresses to arbitration or litigation.
Then, contact an insurance lawyer for an independent review. An attorney can assess whether the denial was valid or whether the insurer is acting unfairly. They’ll also evaluate whether policy language has been wrongly applied or whether your rights under the contract have been violated, including whether the policy itself complies with California law.
Finally, consider whether the denial rises to the level of insurance bad faith. If your insurer has misrepresented coverage, refused to investigate your claim, or failed to communicate in a reasonable timeframe, you may have grounds for a bad faith lawsuit, which could entitle you to damages beyond the original claim amount.
Insurance companies expect many people to give up when faced with a denial. But with the right strategy and strong legal representation, you can push back and demand the protection and compensation your policy promised.
Frequently Asked Questions About UIM Claims
How do I know if the other driver is underinsured?
By comparing their policy limits (typically provided during the claim process) to the total amount of your damages.
Can I use UIM coverage if I was a passenger in someone else’s car?
Yes, depending on the circumstances and how your policy is written. In many cases, you can access your own UIM policy or the driver’s, depending on who carries the coverage.
Can I use my UIM coverage if I was not in a car?
Yes, depending on the circumstances and how your policy is written. California law provides that you can recover UM and UIM benefits if you are a pedestrian, cyclist, motorcyclist, or even on stilts!
Do I have to get my insurer’s permission before settling with the at-fault driver?
Often, yes. Settling without permission can violate the “consent-to-settle” clause in your policy and may bar you from seeking UIM compensation.
Can UIM cover pain and suffering?
Yes. UIM is meant to make up for all uncompensated damages, including medical costs, lost wages, and non-economic losses like pain and suffering.
How long do I have to file a UIM claim in California?
Typically two years from the date of the accident, but deadlines can vary based on when the at-fault policy is exhausted. Consult an attorney promptly to avoid losing your rights.
What if my policy was sold to me incorrectly or doesn’t comply with California law?
This is more common than most people realize, and it can affect both individual policyholders and businesses. An attorney experienced in UIM litigation can review your policy and identify whether the insurer failed to meet its legal obligations, which may open up avenues for recovery beyond what a standard denial would suggest.
The Importance of Legal Advocacy in Complex Insurance Claims
Auto insurance companies are not eager to pay what they owe, especially in large UIM claims. When insurers delay or deny payment unfairly, many policyholders give up rather than fight back. That’s where legal representation becomes essential.
A lawyer begins by evaluating the true value of your case. They’ll assess your current medical bills, projected future care costs, lost wages, and pain and suffering. This allows you to understand what your case is worth and whether the insurance offer falls short.
Next, your attorney ensures that the other driver’s policy is fully exhausted before making a UIM demand. This step is often overlooked by accident victims, but it’s crucial: your own insurer will not consider a UIM claim unless the at-fault party’s coverage has been used up entirely, and the settlement was properly structured to preserve your rights.
Your attorney also takes over handling all communications and negotiations. This protects you from saying something that could be used against you, and frees you from the stress of dealing with adjusters who may pressure you to settle quickly (and cheaply).
If your insurer delays, denies, or undervalues your claim, your lawyer can apply legal pressure to move the process forward. This may involve demanding written justifications, using expert opinions to support your case, or uncovering improper claim-handling practices, including whether the policy itself was sold in violation of state law.
Finally, if your insurer refuses to pay fairly, your attorney can file for arbitration or take the matter to court. In many UIM cases, binding arbitration is required by the insurance policy, but litigation may also be appropriate. This is particularly common if there’s evidence of bad faith or a non-compliant policy.
