Dear [________________________________]:

I. INTRODUCTION AND NATURE OF DEMAND

This firm represents [________________________________] ("our client") in connection with a claim for [UNINSURED / UNDERINSURED] motorist benefits under California Insurance Code § 11580.2 arising from a motor vehicle collision on [__/__/____] in [________________________________], California.

This letter constitutes a formal demand for payment of the full UM/UIM policy limits of $[________________________________]. Our client's total damages far exceed available coverage from all sources.

California Insurance Code § 11580.2 mandates that every automobile liability insurance policy issued or delivered in California include UM/UIM coverage unless the named insured validly waives it in writing. That statutory mandate reflects the Legislature's determination that California motorists deserve protection when struck by uninsured or underinsured drivers. [CARRIER SHORT NAME]'s own insured is precisely the person that protection was designed to protect.

II. CALIFORNIA UM/UIM STATUTORY FRAMEWORK

A. Mandatory Coverage Under Cal. Ins. Code § 11580.2

California Insurance Code § 11580.2 requires every automobile insurer to offer uninsured and underinsured motorist coverage at limits equal to the insured's bodily injury liability limits unless the named insured expressly rejects such coverage in writing. The minimum UM/UIM limits in California, as of January 1, 2025, are $30,000 per person / $60,000 per accident — increased from the prior $15,000/$30,000 minimums by SB 1107 (2022). Our client carries limits of $[________________________________] per person / $[________________________________] per accident.

B. UIM Trigger — "Gap" Offset Rule (§ 11580.2(p))

Under California's UIM offset structure, the insurer's maximum liability equals the insured's UIM limits minus amounts paid by the tortfeasor or other legally liable parties. Accordingly:

Because our client's total damages of $[________________________________] exceed the combined available coverage from all sources, this is a full policy limits case.

C. Stacking Under § 11580.2(p)

California permits inter-policy stacking of UM/UIM coverage under § 11580.2(p). Our client has [________________________________] vehicles listed on the policy. [If applicable: Stacking of coverage across [____] vehicles yields a combined available limit of $[________________________________]. We demand this full stacked amount.]

D. Consent to Settle / Preservation of UIM Rights

Pursuant to Cal. Ins. Code § 11580.2 and the implied covenant of good faith, we hereby formally request written consent to settle with the tortfeasor's carrier, [________________________________], for its policy limits of $[________________________________]. Failure to promptly respond to this consent request may constitute a waiver of subrogation rights and/or bad faith conduct under Moradi-Shalal v. Fireman's Fund Ins. Cos., 46 Cal.3d 287 (1988), and its progeny.

Please provide written consent or a written denial with grounds within [____] calendar days.

E. Arbitration Rights Under § 11580.2(i)

California Insurance Code § 11580.2(i) provides that disputes concerning the amount of damages in UM/UIM cases are subject to binding arbitration upon demand by either party. The parties share arbitration costs equally. Should [CARRIER SHORT NAME] fail to accept this demand, we will invoke arbitration pursuant to § 11580.2(i). Any demand or petition for arbitration must include the declaration required by § 11580.2(i)(3) regarding any workers' compensation claim.

III. POLICY INFORMATION

Our client's documented damages of $[____________] vastly exceed all available coverage. There is no reasonable basis to dispute that this claim has a value at or above the policy limits.

IX. CALIFORNIA BAD FAITH WARNING

[CARRIER SHORT NAME] owes its own insured — our client — the duties imposed by the implied covenant of good faith and fair dealing recognized under California law. These are not abstract obligations; they are enforceable in tort with potentially severe consequences.

A. California Bad Faith Legal Framework

California recognizes both tort and contract theories for insurer bad faith. The California Supreme Court held in Gruenberg v. Aetna Ins. Co., 9 Cal.3d 566 (1973) that the implied covenant of good faith and fair dealing requires an insurer to not unreasonably withhold policy benefits from its insured. An insurer that unreasonably withholds benefits acts in bad faith regardless of whether it disputes coverage or damages in good faith; the standard is objective reasonableness.

Moradi-Shalal v. Fireman's Fund Ins. Cos., 46 Cal.3d 287 (1988) confirmed that while there is no private right of action under Cal. Ins. Code § 790.03, violations of the Fair Claims Settlement Practices Regulations (Cal. Code Regs. tit. 10, §§ 2695.1–2695.14) are powerful evidence of unreasonable conduct in a common law bad faith action.

B. Prompt Payment Obligations

Under Cal. Code Regs. tit. 10, § 2695.7, [CARRIER SHORT NAME] must:

• Acknowledge this claim in writing within 15 calendar days
• Accept or deny the claim, in whole or in part, within 40 calendar days after receiving proof of claim
• Pay any undisputed amount within 30 calendar days of determination
• Provide written 30-day status updates if investigation extends beyond 40 days

C. Available Bad Faith Remedies

If [CARRIER SHORT NAME] unreasonably delays or denies this claim, our client will pursue all available California remedies:

1. Contract damages — all policy benefits wrongfully withheld
2. Consequential damages — all economic losses proximately caused by the bad faith denial/delay
3. Emotional distress damages — recoverable in first-party bad faith actions (Gruenberg, supra)
4. Brandt fees — attorney's fees reasonably incurred to compel payment of policy benefits, recoverable as an element of tort damages (Brandt v. Superior Court, 37 Cal.3d 813 (1985))
5. Punitive damages — upon proof by clear and convincing evidence of malice, fraud, or oppression under Cal. Civ. Code § 3294; California courts have upheld substantial punitive damage awards against insurers who engage in systematic or egregious bad faith claims handling

D. Specific Violations That Will Be Alleged

If this claim is not resolved, we will allege violations of:

☐ Cal. Ins. Code § 790.03(h)(1) — misrepresentation of policy provisions
☐ Cal. Ins. Code § 790.03(h)(3) — failure to adopt reasonable investigation standards
☐ Cal. Ins. Code § 790.03(h)(5) — failure to effectuate prompt, fair, equitable settlement
☐ Cal. Ins. Code § 790.03(h)(6) — compelling litigation by offering substantially less than owed
☐ Cal. Code Regs. tit. 10, § 2695.7(b) — failure to acknowledge claim within 15 days
☐ Cal. Code Regs. tit. 10, § 2695.7(b)(1) — failure to accept or deny within 40 days
☐ Cal. Code Regs. tit. 10, § 2695.7(g) — failure to provide reasonable explanation for denial

X. ARBITRATION DEMAND (CONDITIONAL)

A. Policy Arbitration Clause

The policy ☐ contains ☐ does not contain an arbitration clause for UM/UIM disputes. Regardless of policy language, Cal. Ins. Code § 11580.2(i) provides a statutory right to binding arbitration of UM/UIM damage disputes.

B. Notice of Intent to Arbitrate

If [CARRIER SHORT NAME] does not accept this demand by the deadline below, this letter shall serve as advance notice of our intent to demand binding arbitration under Cal. Ins. Code § 11580.2(i) and the applicable policy provisions. A formal arbitration demand will follow.

Note: Under § 11580.2(i)(1), an insured must institute arbitration proceedings within two years of the date of accident by notifying the insurer in writing via certified mail, return receipt requested. The arbitration costs are shared equally between the parties.

XI. RESPONSE DEADLINE AND CONSEQUENCES

THIS DEMAND EXPIRES AT 5:00 P.M. PACIFIC TIME ON [__/__/____].

If [CARRIER SHORT NAME] fails to accept this demand in full by the deadline:

1. We will file a demand for binding arbitration under Cal. Ins. Code § 11580.2(i) and seek all UM/UIM benefits through that proceeding.
2. We will file a separate bad faith action in California Superior Court, [________________________________] County, seeking all remedies described in Section IX above, including Brandt fees and punitive damages under Cal. Civ. Code § 3294.
3. We will file a formal complaint with the California Department of Insurance (CDI), Consumer Services Division, 300 Capitol Mall, Suite 1700, Sacramento, CA 95814; telephone: (800) 927-4357; www.insurance.ca.gov.
4. We reserve all rights under California law.

XII. DOCUMENT PRESERVATION NOTICE

This letter constitutes formal notice requiring [CARRIER SHORT NAME] and its parent, affiliates, third-party administrators, and agents to immediately suspend any routine document destruction protocols and to preserve all documents, electronically stored information (ESI), and tangible items relating to this claim, including without limitation:

• Complete claim file in all versions and formats
• All internal communications, adjuster notes, diary entries, and activity logs
• All reserve information and reserve change documentation
• Claim handling guidelines, procedures, and training materials
• All communications with our client or this office
• All photographs, inspection reports, expert evaluations, and estimates
• Quality assurance, audit, and supervisory review materials

XIII. CONCLUSION

Our client was injured through no fault of their own by a motorist who lacked adequate insurance. [CARRIER SHORT NAME] collected premiums precisely for this contingency. Our client's damages are thoroughly documented, clearly exceed the available coverage, and entitle our client to the full UM/UIM policy limits.

We urge [CARRIER SHORT NAME] to evaluate this claim fairly, honor its obligations to its own insured, and tender the full policy limits of $[____________] by [__/__/____].

Respectfully submitted,
