California law treats demand letters and pre-suit notices along a spectrum: some are voluntary settlement tools, while others are mandatory conditions precedent that can bar suit if omitted or defective.
Four statutory regimes drive California pre-suit practice: the Government Claims Act, MICRA's notice of intent, the Consumers Legal Remedies Act, and UM/UIM arbitration procedures. Whether a demand is voluntary or mandatory determines whether an omission or defect affects only settlement posture or bars the claim entirely. The pre-suit demand rules that apply in California vary by claim type and defendant.
This article covers California demand-letter classifications, mandatory notice regimes, limitation periods, and recurring defects in personal injury, medical malpractice, government-entity, and insurance claims, as of June 2026.
What Counts as a Demand Letter Under California Law?
California recognizes voluntary demands that initiate settlement and mandatory statutory notices that are conditions precedent to suit. The classification determines whether a defect affects settlement posture or suit viability.
A voluntary third-party liability demand derives its force from the insurer’s duty to accept reasonable settlements. Comunale v. Traders & General Ins. Co. (1958) 50 Cal.2d 654 tied an unwarranted refusal to settle within policy limits to breach of the implied covenant of good faith and fair dealing, and Crisci v. Security Ins. Co. (1967) 66 Cal.2d 425 confirmed liability may arise without actual dishonesty, fraud, or concealment.
Mandatory instruments operate by statute. A Government Claims Act claim under Gov. Code § 945.4, a CLRA notice under Civil Code § 1782, and a MICRA notice under CCP § 364 impose separate procedural requirements and consequences.
Voluntary instruments include the CCP § 999.1 time-limited demand and the CCP § 998 offer to compromise. A non-compliant § 999.1 demand cannot support a later bad-faith failure-to-settle claim.
When Does California Require Pre-Suit Notice?
Three statutory regimes commonly impose pre-suit notice or claim-presentation requirements. Each uses a different compliance standard, deadline, and remedy for noncompliance.
The Government Claims Act requires a written claim before suits for money or damages against a public entity when claim presentation is required. Gov. Code § 945.4 provides that no such suit may be brought until a written claim has been presented and acted upon or deemed rejected.
The Consumers Legal Remedies Act requires 30 days’ written notice before a damages action under Civil Code § 1782(a). The notice must identify the alleged violations and demand correction, repair, replacement, or other rectification.
MICRA requires 90 days’ notice of intent under CCP § 364(a) before an action based on a health care provider’s professional negligence. The notice has no required form, but it must state the legal basis for the claim and the type of loss sustained, including the nature of the injuries suffered.
The compliance standards are distinct:
- Government Claims Act: Substantial compliance may suffice if the claim gives notice that the claimant is attempting to file a valid claim and that litigation will result if unresolved, per State of California v. Superior Court (Bodde) (2004) 32 Cal.4th 1234.
- CLRA § 1782: The statute requires certified or registered mail with return receipt requested.
- MICRA § 364: Woods v. Young (1991) 53 Cal.3d 315 held that noncompliance does not invalidate court proceedings, though attorney discipline may result.
Government Claims Act Demand Requirements Under Gov. Code § 910
Government-entity claims carry the strictest pre-suit consequence because claim presentation is a condition precedent. Defects in timing, delivery, or statutory content can defeat the action.
Required Content Under Gov. Code § 910
Under Gov. Code § 910, every claim must include the following:
- The claimant’s name and post office address, and the address to which notices are to be sent
- The date, place, and circumstances of the occurrence giving rise to the claim
- A general description of the injury, damage, or loss
- The names of any public employees who caused the injury, if known
- For claims under $10,000: the specific dollar amount, estimated prospective damages, and the basis of computation
- For claims over $10,000: no dollar amount, but a statement of whether it would be a limited civil case
Under Gov. Code § 910.2, the claim must be signed by the claimant or an authorized representative.
Designated Recipients Under Gov. Code § 915
Gov. Code § 915 specifies delivery by entity type:
- State agencies: An office of the Department of General Services
- Counties, cities, and school districts: Clerk, secretary, or auditor of the entity; may be mailed to the governing body at its principal office; electronic submission permitted only if authorized by ordinance or resolution
- Judicial branch: Designated court officer
- California State University: Trustees of the California State University
DiCampli-Mintz v. County of Santa Clara (2012) 55 Cal.4th 983 rejected delivery to a risk management department as substitute presentation. Accurate injury dating and case chronologies are therefore central to claim-presentation compliance.
Gov. Code § 911.2 sets the presentation period at six months after accrual for death, personal injury, or personal property claims, and one year for other causes of action. After rejection, Gov. Code § 945.6 sets the suit deadline at six months after a § 913 rejection notice is mailed, or two years from accrual if no compliant notice issues.
MICRA Notice and CCP § 340.5 Limitations
Medical malpractice pre-suit timing turns on the interaction between CCP § 364 notice and the CCP § 340.5 limitation period. Injury dates, discovery dates, and treatment chronology determine whether notice extends the filing window.
Notice of Intent Under CCP § 364
CCP § 364(a) bars any action based on professional negligence unless the defendant received at least 90 days’ prior notice of intent to sue. Section 364(b) requires the notice to state the legal basis of the claim and the type of loss sustained, including, with specificity, the nature of the injuries. The Doe defendant exception under § 364(e) excuses notice for defendants identified by fictitious name.
Limitation Period Under CCP § 340.5
CCP § 340.5 sets the filing period at three years from injury or one year from discovery, whichever occurs first. The three-year outer limit is absolute except for tolling on proof of fraud, intentional concealment, or the presence of a foreign body with no therapeutic or diagnostic purpose or effect. For minors, the period runs three years from the wrongful act, except that a minor under the full age of six has until the later of three years or the eighth birthday.
How § 364 Notice Interacts with § 340.5
Notice served before the final 90 days requires the plaintiff to wait 90 days and still file within the limitation period. Notice served during the final 90 days tolls the period 90 days from service. Under Woods, that produces one year and 90 days for the discovery period; under Russell v. Stanford University Hospital (1997) 15 Cal.4th 783, it produces three years and 90 days for the outer limit. Accurate clinical record review supports the dating analysis.
UM/UIM Demand Mechanics in California
Uninsured and underinsured motorist demands operate under Ins. Code § 11580.2. The statute mandates arbitration of disputed coverage and damages while preserving the insurer’s good-faith obligations.
UM Claim Accrual and Arbitration Requirement
Section 11580.2(f) requires every UM policy to provide that legal entitlement to recover, and the amount of damages, be determined by agreement or arbitration. Under § 11580.2(i), a UM claim does not accrue unless, within two years of the accident, the insured has done one of the following:
- Filed suit against the uninsured motorist
- Reached a written agreement on the amount due
- Formally instituted arbitration by written notice sent certified mail, return receipt requested
The insurer must notify the insured of the applicable limitations period at least 30 days before expiration; failure tolls the period 30 days from actual notice.
UIM Coverage Trigger
UIM coverage follows a different accrual rule. Under § 11580.2(p)(3), coverage does not attach until the tortfeasor’s liability limits are exhausted by judgment or settlement and proof of payment is submitted to the UIM insurer.
Good-Faith Obligations
The arbitration mandate does not eliminate bad-faith exposure. Kransco v. American Empire Surplus Lines Ins. Co. (2000) 23 Cal.4th 390 held that the duty of good faith is unconditional and independent of the insured’s performance. Chateau Chamberay Homeowners Ass'n v. Associated Int'l Ins. Co. (90 Cal. App.4th 335) established that the genuine dispute doctrine may avoid bad-faith liability where denial or delay rests on reasonable grounds, but Maslo v. Ameriprise Auto & Home Ins. (B249271) confirmed the insurer still must fairly investigate a clear claim before forcing arbitration.
California Statute of Limitations by Claim Type
Claim classification determines the limitation period, accrual rule, and whether pre-suit notice is required. The following table summarizes the principal personal injury, medical malpractice, government-entity, UM/UIM, and insurance claim deadlines discussed above.
Common Errors That Defeat a California Demand or Notice
Recurring defects usually involve delivery, content, or limitations calculations. The consequences differ by statutory regime.
Government Claims Act errors are the most severe because claim presentation is a condition precedent. Under DiCampli-Mintz v. County of Santa Clara, delivery to county counsel or a risk management department does not substitute for delivery to the statutory recipient unless a deemed-compliance rule applies through timely actual receipt by the proper officer or body.
Common Government Claims Act defects include:
- Late presentation after the six-month or one-year window.
- Delivery to the wrong public office or official.
- Omission of the required amount for a sub-$10,000 claim.
- Inclusion of a prohibited dollar amount for a claim exceeding $10,000.
CLRA errors include premature damages filing, use of email, fax, or standard mail instead of certified or registered mail, delivery to the wrong address, and disregard of the 30-day safe harbor. A damages action cannot be maintained if the defendant gives or agrees to give an appropriate remedy within 30 days after receiving notice.
MICRA § 364 errors are less severe because the notice is non-jurisdictional. Omission does not invalidate the court proceeding under Woods, but attorney discipline remains a statutory consequence.
Claim Classification Controls California Demand Timing
California’s pre-suit framework turns on claim classification. A government entity claim requires a § 910-compliant filing to the correct § 915 recipient; a malpractice demand requires § 364 notice measured against § 340.5; and a UM claim requires written arbitration notice within two years of the accident.
Compliance depends on accurate injury dates, discovery points, treatment timelines, and supporting medical records. Legal AI tools support medical record review, defensible chronologies, and documentation workflows tied to statutory deadlines.
