Why did my California underinsured motorist coverage pay nothing?

What this assumes

• The policy is a California automobile policy and the coverage in question is the underinsured half of uninsured motorist coverage, which California requires to be offered as a single coverage with uninsured motorist limits equal to those in the underlying policy [1].

• The injury is bodily injury. Uninsured and underinsured motorist coverage does not apply, as primary or as excess, to property damage sustained by the insured [1].

• The at-fault vehicle was insured. If it carried no bodily injury liability insurance at all, the uninsured rather than the underinsured half responds [1].

• You are asking about your own coverage rather than about what the at-fault driver's insurer owes.

What changes the answer

• Your own uninsured motorist limit, which is the number the comparison is made against. An insurer is not required to offer more than $30,000 per person and $60,000 per accident of that coverage no matter how high your liability limits are [1], so a policy with high liability limits and minimum uninsured motorist limits is common and is exactly the shape that produces this outcome.

• What the at-fault driver actually carried. Their limits being at or above yours is the difference between a claim and no claim.

• Whether the liability limits were exhausted by payment and proof was submitted, which is a precondition rather than a formality [1].

• Whether anything was settled without the insurer's written consent. The coverage does not apply to an injury for which the insured settled with or took judgment against a potentially liable person without that consent [1].

• Whether a workers compensation recovery is in play, since the loss payable may be reduced by amounts paid and the present value of amounts payable under any workers compensation law, excluding nonoccupational disability benefits [1].

Where it varies by state, form, carrier, or fact

• This is California's construction and it is not universal. Other states define an underinsured motor vehicle by comparing the other driver's limits to the injured person's damages rather than to their own limit, which produces a different answer on the same facts. The statute cited here is the California Insurance Code and applies to policies issued or delivered in California or covering a vehicle principally used or garaged there [1].

• Limits cannot be stacked. Regardless of the number of vehicles, persons covered, claims made or premiums paid, the limits of two or more vehicles or two or more policies may not be added together or combined to determine what is available [1].

• Whether uninsured motorist coverage is present at all depends on whether it was waived. It must be in every bodily injury liability policy unless deleted by a written agreement in the exact form the statute prescribes, and that agreement carries forward through renewals and replacements and through reinstatement within 30 days of a lapse [1].

Next actions

1. Read the declarations page for your uninsured motorist limit rather than your liability limit. They are frequently different, and it is the uninsured motorist number that governs this coverage.

2. Ask your insurer, in writing, what limits the at-fault vehicle carried and whether those limits were exhausted by payment.

3. Ask whether a written waiver or reduction of uninsured motorist coverage is on file for your policy, and ask for a copy of the signed document if one exists.

4. If the outcome turns on the amount of the loss rather than on the limits, note that whether you are legally entitled to recover and how much is decided by agreement or, failing that, by arbitration before a single neutral arbitrator [1].

   What this source supports (32)

   • Section 11580.2(a)(1) requires every policy of bodily injury liability insurance covering liability arising out of the ownership, maintenance or use of a motor vehicle that is issued or delivered in California to a vehicle owner or operator, or issued by a California-licensed insurer on a vehicle then principally used or principally garaged in California, to contain or have added by endorsement a provision insuring the insured against the owner or operator of an uninsured motor vehicle.
   • Section 11580.2(a)(1) sets the required limits of that provision as at least equal to the limits specified in subdivision (m) and in no case less than the financial responsibility requirements specified in Vehicle Code section 16056.
   • Section 11580.2(a)(1) permits the insurer and any named insured, before or after issuance or renewal, to agree in writing to delete the uninsured motorist provision completely, to delete the coverage when the vehicle is operated by a natural person or persons designated by name, or to provide the coverage in an amount less than subdivision (m) requires but not less than the Vehicle Code section 16056 financial responsibility requirements.
   • Section 11580.2(a)(2) and (a)(3) prescribe the exact form of words a deletion or reduced-limit agreement must take, and section 11580.2(a)(2) provides that execution of the agreement relieves the insurer of liability under the section while the agreement remains in effect.
   • Section 11580.2(a)(1) provides that a deletion or amount agreement binds every insured to whom the policy or endorsement provisions apply while the policy is in force, and continues to bind with respect to any continuation or renewal, any other policy that extends, changes, supersedes or replaces the policy issued by the same insurer, and reinstatement of the policy within 30 days of any lapse.
   • Section 11580.2(a)(1) excludes a policy from the application of the section if the automobile liability coverage is provided only on an excess or umbrella basis.
   • Section 11580.2(a)(1) states that nothing in the section requires uninsured motorist coverage to be offered or provided in a homeowner policy, comprehensive personal liability policy, premises liability policy, special multiperil policy, or any other policy or endorsement where automobile liability coverage is offered as incidental to some other basic coverage.
   • Section 11580.2(m) requires uninsured motorist coverage to be offered with limits equal to the limits of liability for bodily injury in the underlying policy, but provides that it need not be offered with limits in excess of thirty thousand dollars for bodily injury to or death of one person in any one accident and, subject to that per-person limit, sixty thousand dollars for bodily injury to or death of two or more persons in any one accident.
   • Section 11580.2(a)(1) states the required limits conjunctively, as at least equal to subdivision (m) and in no case less than the Vehicle Code section 16056 financial responsibility requirements, so the operative minimum is whichever of the two amounts is higher on the date in question; on that reading the subdivision (m) amounts of thirty thousand and sixty thousand dollars are a ceiling on what an insurer must offer rather than a floor on what the coverage must provide.
   • Section 11580.2(p)(2) defines an underinsured motor vehicle as a motor vehicle that is an insured motor vehicle but insured for an amount that is less than the uninsured motorist limits carried on the motor vehicle of the injured person.
   • Section 11580.2(p)(4) provides that when bodily injury is caused by one or more motor vehicles, whether insured, underinsured or uninsured, the maximum liability of the insurer providing underinsured motorist coverage shall not exceed the insured's underinsured motorist coverage limits, less the amount paid to the insured by or for any person or organization that may be held legally liable for the injury.
   • Read together, section 11580.2(p)(2) and section 11580.2(p)(4) make California underinsured motorist coverage a difference-in-limits coverage rather than an additional layer of its own: on that reading it responds only where the at-fault vehicle is insured for less than the injured person's own uninsured motorist limit, and it pays at most that limit reduced by what the liable parties paid, so an at-fault driver whose liability limits equal or exceed the injured person's uninsured motorist limit leaves nothing for the coverage to pay.
   • Section 11580.2(p)(3) provides that underinsured motorist coverage does not apply to any bodily injury until the limits of the bodily injury liability policies applicable to all insured motor vehicles causing the injury have been exhausted by payment of judgments or settlements, and proof of the payment is submitted to the insurer providing the underinsured motorist coverage.
   • Section 11580.2(q) provides that regardless of the number of vehicles involved, persons covered, claims made, premiums paid or premiums shown on the policy, in no event shall the limit of liability for two or more motor vehicles or two or more policies be added together, combined or stacked to determine the limit of insurance coverage available to injured persons.
   • Section 11580.2(b) conditions uninsured motorist coverage, with respect to an uninsured motor vehicle whose owner or operator is unknown, on the bodily injury having arisen out of physical contact of the automobile with the insured or with an automobile that the insured is occupying.
   • Section 11580.2(b)(2) requires that the insured or someone acting on the insured's behalf report the accident within 24 hours to the police department of the city where the accident occurred, or in unincorporated territory to the sheriff of the county or the local headquarters of the California Highway Patrol, and file with the insurer within 30 days thereafter a statement under oath that a cause of action exists against a person whose identity is unascertainable, setting forth supporting facts.
   • Section 11580.2(b) treats an insured motor vehicle as an uninsured motor vehicle where its liability insurer is unable to make payment within its limits because of insolvency, and limits that solvency protection to accidents occurring during a policy period in which the insured's own motor vehicle coverage is in effect where the tortfeasor's liability insurer becomes insolvent within one year of the accident.
   • Section 11580.2(c)(1) provides that the coverage does not apply, either as primary or as excess coverage, to property damage sustained by the insured.
   • Section 11580.2(c)(3) provides that the coverage does not apply to bodily injury of the insured with respect to which the insured or the insured's representative, without the written consent of the insurer, made any settlement with or prosecuted to judgment any action against any person who may be legally liable.
   • Section 11580.2(c)(6) provides that the coverage does not apply to bodily injury of the insured while occupying a motor vehicle owned by an insured, or leased to an insured under a written contract for a period of six months or longer, unless the occupied vehicle is an insured motor vehicle.
   • Section 11580.2(c)(4) provides that the coverage does not apply in any instance where it would inure directly or indirectly to the benefit of any workers compensation carrier or any person qualified as a workers compensation self-insurer, or directly to the benefit of the United States or any state or political subdivision.
   • Section 11580.2(f) requires the policy or endorsement to provide that whether the insured is legally entitled to recover damages, and if so the amount, is determined by agreement between the insured and the insurer or, in the event of disagreement, by arbitration conducted by a single neutral arbitrator.
   • Section 11580.2(i)(1) provides that no cause of action accrues to the insured unless, within two years from the date of the accident, suit for bodily injury has been filed against the uninsured motorist in a court of competent jurisdiction, agreement as to the amount due under the policy has been concluded, or the insured has formally instituted arbitration proceedings by notifying the insurer in writing sent by certified mail, return receipt requested.
   • Section 11580.2(i)(2) requires an arbitration instituted under the section to be concluded within five years from the institution of the proceeding, or where the insured has a workers compensation claim arising from the same accident, within three years of the date that claim is concluded or within the five-year period, whichever occurs later.
   • Section 11580.2(k) requires an insurer whose insured has a pending uninsured motorist claim to notify the insured in writing of the applicable statute of limitation at least 30 days before it expires, and provides that failure to give the notice tolls the limitation for 30 days from the date the notice is actually given; the notice is not required if the insurer has received notice that the insured is represented by an attorney.
   • Section 11580.2(g) entitles the insurer paying a claim under an uninsured motorist endorsement to be subrogated to the insured's rights against any person legally liable to the extent of the payment, and permits that action to be brought within three years from the date payment was made.
   • Section 11580.2(h) requires that an insured entitled to recovery be reimbursed without being required to sign any release or waiver of rights under any other applicable insurance coverage, and prohibits payment being delayed or made contingent upon decisions as to liability or distribution of loss costs under other bodily injury liability insurance or any bond applicable to the accident.
   • Section 11580.2(h)(1) permits a loss payable under uninsured motorist coverage to be reduced by the amount paid and the present value of all amounts payable to the insured under any workers compensation law, exclusive of nonoccupational disability benefits.
   • Section 11580.2(n) requires uninsured and underinsured motorist coverage to be offered as a single coverage, with underinsured motorist limits equal to the insured's uninsured motorist limits in the underlying policy, and permits an insurer to offer underinsured limits in excess of the uninsured motorist coverage.
   • Section 11580.2(p)(7) requires underinsured motorist coverage to be included in all policies of bodily injury liability insurance providing uninsured motorist coverage issued or renewed on or after July 1, 1985, and preserves the effect of an agreement to delete uninsured motorist coverage executed before that date.
   • Section 11580.2(d) permits the policy or endorsement to provide that where the insured has coverage available under more than one uninsured motorist coverage provision, damages shall not be deemed to exceed the higher of the applicable limits of the respective coverages and shall be prorated between the applicable coverages as the limits of each bear to the total of the limits.
   • Section 11580.2(e) permits the policy or endorsement to provide that where the insured has valid and collectible automobile medical payment insurance available, the damages recoverable under uninsured motorist coverage are reduced by the amounts paid or due to be paid under that medical payment insurance.

   The most consequential section for a California auto claim, and the one most often described incorrectly. Two entries are readings rather than quotations, and each says so in its own text so it cannot be mistaken for the statute's words: the interaction between subdivision (m) and Vehicle Code section 16056, and the difference-in-limits effect of subdivisions (p)(2) and (p)(4).
