2. INTRODUCTION
2.1. Plaintiff [PLAINTIFF NAME] ("Plaintiff"), by and through undersigned counsel, brings this action against Defendants for personal injuries proximately caused by the defective design of [PRODUCT TYPE] (the "Product"), which Defendants designed, manufactured, marketed, distributed, and/or sold. Plaintiff alleges as follows on personal knowledge as to facts pertaining to Plaintiff and on information and belief as to all other matters.
3. PARTIES
3.1. Plaintiff [PLAINTIFF NAME] is, and at all relevant times was, an individual residing in [COUNTY] County, California.
3.2. Defendant [MANUFACTURER NAME] ("Manufacturer") is, and at all relevant times was, a corporation organized under the laws of [STATE] with its principal place of business in [CITY, STATE], engaged in the business of designing, manufacturing, testing, marketing, and selling the Product, and regularly conducting business in California and in this County.
3.3. Defendant [DISTRIBUTOR/SELLER NAME] ("Seller") is, and at all relevant times was, a [entity] engaged in the business of distributing and/or selling the Product for use in California.
3.4. The true names and capacities of Defendants sued as DOES 1 through 50 are unknown to Plaintiff, who therefore sues them by fictitious names pursuant to Code of Civil Procedure § 474 and will amend when ascertained.
3.5. Plaintiff is informed and believes that each Defendant was the agent, employee, alter ego, successor-in-interest, or co-participant of each other Defendant and acted within the scope of that relationship. Each Defendant is a participant in the chain of distribution of the Product within the meaning of Greenman v. Yuba Power Products, Inc., 59 Cal.2d 57 (1963), and Vandermark v. Ford Motor Co., 61 Cal.2d 256 (1964).
4. JURISDICTION AND VENUE
4.1. This Court has subject-matter jurisdiction under Article VI, § 10 of the California Constitution and Code of Civil Procedure § 410.10. The amount in controversy exceeds $25,000, vesting unlimited civil jurisdiction.
4.2. This Court has personal jurisdiction over each Defendant because each Defendant transacts substantial business in California and/or purposefully introduced the Product into the stream of commerce with the expectation it would be used by California consumers.
4.3. Venue is proper in this County under Code of Civil Procedure §§ 395 and 395.5 because [the injury occurred / the Product was sold / a Defendant resides or transacts business] in this County.
5. FACTUAL ALLEGATIONS
A. The Product
5.1. The Product at issue is [PRODUCT NAME / MODEL / DESCRIPTION; model year; serial/lot number] (the "Product").
5.2. The Product was designed, manufactured, marketed, distributed, and/or sold by Defendants and reached Plaintiff without substantial change in the condition in which it was sold.
B. The Design Defect
5.3. The Product's design was defective in that [describe the design feature(s) that created the hazard, e.g., absence of a guard, interlock, rollover protection, thermal cutoff, structural reinforcement, software fail-safe].
5.4. The design defect rendered the Product unsafe for its intended and reasonably foreseeable uses, including [USE].
5.5. The risk presented by the design — [DESCRIBE HAZARD] — was a foreseeable risk of harm at the time of design, manufacture, and distribution.
C. Feasible Safer Alternative Design
5.6. At the time the Product was designed and manufactured, a reasonable, technically and economically feasible alternative design existed that would have reduced or prevented the harm, namely: [DESCRIBE THE SAFER ALTERNATIVE DESIGN].
5.7. The alternative design was feasible because [the technology was available; competitors used it; applicable standards specified it; the additional cost was modest; utility was not impaired — [____]], and its omission rendered the Product's design defective under the risk-benefit standard of Barker v. Lull Engineering Co., 20 Cal.3d 413 (1978).
D. Plaintiff's Use and Injury
5.8. On or about [__/__/____], Plaintiff [purchased / acquired / used] the Product and used it in a manner that was intended and reasonably foreseeable.
5.9. On or about [__/__/____], as a direct and proximate result of the design defect, Plaintiff sustained [INJURY DESCRIPTION], requiring medical treatment at [PROVIDER/HOSPITAL].
5.10. Plaintiff did not misuse, alter, or modify the Product in any manner that was not reasonably foreseeable.
6. FIRST CAUSE OF ACTION — STRICT PRODUCTS LIABILITY: DESIGN DEFECT
(Against All Defendants)
6.1. Plaintiff realleges and incorporates Paragraphs 1.1 through 5.10 as though fully set forth.
6.2. Defendants designed, manufactured, distributed, and/or sold the Product and placed it into the stream of commerce.
6.3. The Product was defective in design when it left Defendants' possession.
6.4. Consumer-expectation prong. The Product failed to perform as safely as an ordinary consumer would have expected when used in an intended or reasonably foreseeable manner. Barker v. Lull Engineering Co., 20 Cal.3d 413 (1978); CACI No. 1203. The everyday experience of the Product's users permits the conclusion that the design did not meet minimum safety expectations. Soule v. General Motors Corp., 8 Cal.4th 548 (1994).
6.5. Risk-benefit prong (pleaded in the alternative). The design of the Product was a substantial factor in causing Plaintiff's harm, and the benefits of the challenged design do not outweigh the risks inherent in that design. On this theory Defendants bear the burden of proving that the benefits outweigh the risks, considering the gravity and likelihood of the danger, the feasibility of a safer alternative design, the cost of an improved design, and the adverse consequences to the product and consumer of an alternative design. Barker v. Lull Engineering Co., 20 Cal.3d 413 (1978); CACI No. 1204.
6.6. The design defect was a substantial factor in causing Plaintiff's harm. California does not require a separate showing that the Product was "unreasonably dangerous." Cronin v. J.B.E. Olson Corp., 8 Cal.3d 121 (1972).
6.7. As a direct and proximate result, Plaintiff has suffered general and special damages in amounts to be proven at trial.
7. SECOND CAUSE OF ACTION — NEGLIGENT DESIGN
(Against All Defendants)
7.1. Plaintiff realleges and incorporates Paragraphs 1.1 through 6.7 as though fully set forth.
7.2. Defendants owed Plaintiff and other foreseeable users a duty to exercise reasonable care in the design of the Product, including a duty to conduct adequate design testing and hazard analysis and to adopt feasible safer designs. See CACI No. 1220.
7.3. Defendants breached that duty by [failing to test; ignoring known design hazards; failing to incorporate available safety technology; prioritizing cost over safety; disregarding industry standards — [____]].
7.4. Defendants knew or, in the exercise of reasonable care, should have known that the Product's design created an unreasonable risk of harm.
7.5. Defendants' negligence was a substantial factor in causing Plaintiff's harm, resulting in general and special damages in amounts to be proven at trial.
8. THIRD CAUSE OF ACTION — BREACH OF IMPLIED WARRANTY OF MERCHANTABILITY
(Against All Defendants)
8.1. Plaintiff realleges and incorporates Paragraphs 1.1 through 7.5 as though fully set forth.
8.2. Pursuant to California Commercial Code § 2314, Defendants impliedly warranted that the Product was merchantable and fit for the ordinary purposes for which such goods are used. A product whose design is unfit for safe ordinary use is not merchantable.
8.3. The Product was not merchantable because of its defective design, and that breach was a substantial factor in causing Plaintiff's injuries. Plaintiff is excused from any pre-suit notice requirement as a remote purchaser; in the alternative, Plaintiff gave notice within a reasonable time after discovery.
8.4. As a direct and proximate result, Plaintiff has suffered general and special damages in amounts to be proven at trial.
9. DAMAGES
9.1. Economic (Special) Damages. Past and future medical, hospital, and rehabilitative expenses; past and future lost earnings and loss of earning capacity; property damage; and out-of-pocket expenses, in amounts to be proven at trial.
9.2. Non-Economic (General) Damages. Past and future physical pain, mental suffering, loss of enjoyment of life, disfigurement, physical impairment, inconvenience, anxiety, and emotional distress, in amounts to be proven at trial.
9.3. Punitive and Exemplary Damages. Pursuant to California Civil Code § 3294, Plaintiff seeks punitive damages on grounds that Defendants acted with malice, oppression, or fraud, including conscious disregard of known design risks to consumer safety, proven by clear and convincing evidence.
10. PRAYER FOR RELIEF
WHEREFORE, Plaintiff prays for judgment against Defendants, and each of them, jointly and severally, as follows:
- A. General damages according to proof;
- B. Special damages, including past and future medical expenses and lost earnings, according to proof;
- C. Punitive and exemplary damages pursuant to Civil Code § 3294;
- D. Prejudgment and post-judgment interest as allowed by law;
- E. Costs of suit;
- F. Attorneys' fees where authorized by statute or contract; and
- G. Such other and further relief as the Court deems just and proper.
11. DEMAND FOR JURY TRIAL
Plaintiff demands a trial by jury on all issues so triable, pursuant to Code of Civil Procedure § 631 and California Constitution, Article I, § 16.

14. CALIFORNIA PRACTICE NOTES
-
Barker two-prong test. A product is defective in design if either (1) it failed to perform as safely as an ordinary consumer would expect when used in an intended or reasonably foreseeable manner (consumer-expectation prong), OR (2) on a risk-benefit weighing, the benefits of the challenged design do not outweigh its risks. Barker v. Lull Engineering Co., 20 Cal.3d 413 (1978). Plead both in the alternative.
-
Burden-shifting on risk-benefit. Once the plaintiff proves the design was a substantial factor in causing the injury, the burden shifts to the defendant to prove that the benefits of the design outweigh its risks. This burden-shift is a signature California feature and should be pleaded.
-
Soule limits the consumer-expectation prong. The consumer-expectation prong is available only where the everyday experience of the product's users permits a conclusion about minimum safety; for complex designs whose safety is outside common experience (e.g., crashworthiness mechanics), the risk-benefit prong governs and expert testimony is required. Soule v. General Motors Corp., 8 Cal.4th 548 (1994).
-
No "unreasonably dangerous" element. Unlike Restatement (Second) § 402A jurisdictions, California rejects "unreasonably dangerous" as a separate element. Cronin v. J.B.E. Olson Corp., 8 Cal.3d 121 (1972). California has not adopted the Restatement (Third) reasonable-alternative-design requirement as an element, although a feasible alternative is central to risk-benefit proof.
-
Prescription drugs. Strict design-defect liability does not apply to prescription drugs under comment k. Brown v. Superior Court, 44 Cal.3d 1049 (1988). Use warning/negligence theories for those products.
-
Pure comparative fault. Plaintiff's fault reduces but does not bar recovery, and comparative principles apply to strict products liability. Li v. Yellow Cab Co., 13 Cal.3d 804 (1975); Daly v. General Motors Corp., 20 Cal.3d 725 (1978).
-
Statute of limitations. Two years from accrual under CCP § 335.1; the discovery rule may delay accrual for latent injuries. California has no general products statute of repose.
-
Damages pleading. CCP § 425.10 prohibits stating a specific dollar amount of personal-injury damages in the complaint; serve a § 425.11 statement of damages before default. A § 425.115 punitive-damages statement is required before a default judgment for punitive damages.
-
Punitive damages. Civil Code § 3294 requires clear-and-convincing evidence of malice, oppression, or fraud; for corporate defendants the conduct must be authorized or ratified by an officer, director, or managing agent.

About This Template
Product liability cases are brought when a defective product causes injury, either because of a design flaw, a manufacturing defect, or a missing warning. These claims are usually fought by large corporate defendants and their insurers, so the paperwork has to be thorough from the start. Well-drafted complaints and demand letters identify the specific defect, the chain of distribution, and the legal theory clearly enough to survive early motions.
