COMPLAINT AND DEMAND FOR JURY TRIAL
(Tier [____] — Ariz. R. Civ. P. 26.2)
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, Arizona.
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], and is a "manufacturer" within the meaning of A.R.S. § 12-681, engaged in the business of designing, manufacturing, testing, marketing, and selling the Product, and regularly conducting business in Arizona.
3.3. Defendant [DISTRIBUTOR/SELLER NAME] ("Seller") is, and at all relevant times was, a [entity] and a "seller" within the meaning of A.R.S. § 12-681, engaged in the business of distributing and/or selling the Product for use in Arizona.
3.4. The true names and capacities of the fictitiously named Defendants are unknown to Plaintiff, who will amend this Complaint to state their true names and capacities 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, and that each was engaged in the business of placing the Product into the stream of commerce.
4. JURISDICTION AND VENUE
4.1. This Court has subject-matter jurisdiction under Article VI, § 14 of the Arizona Constitution.
4.2. This Court has personal jurisdiction over each Defendant because each Defendant transacts substantial business in Arizona and/or purposefully introduced the Product into the stream of commerce with the expectation that it would be purchased or used by Arizona consumers, consistent with Ariz. R. Civ. P. 4.2 and due process.
4.3. Venue is proper in this County under A.R.S. § 12-401 because [a Defendant resides or has a place of business in this County / the injury occurred in this County / the obligation or cause arose in this County].

A. The Product
5.1. The Product at issue is [PRODUCT NAME / MODEL / DESCRIPTION / MODEL YEAR / SERIAL OR 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. The Product's intended use was [DESCRIBE INTENDED USE].
B. The Design Defect
5.3. The Product was defective and unreasonably dangerous in its design. Specifically, the design [describe the design defect — e.g., lack of a guard, instability, inadequate fail-safe, hazardous material selection, failure to incorporate available safety technology — [____]].
5.4. Consumer-Expectation Test. The Product failed to perform as safely as an ordinary consumer would expect when used in an intended or reasonably foreseeable manner. An ordinary consumer would expect that [STATE EXPECTATION], and the Product did not meet that expectation. Dart v. Wiebe Mfg., Inc., 147 Ariz. 242, 709 P.2d 876 (1985).
5.5. Risk-Utility Test. Considering the gravity and likelihood of the danger, the availability and feasibility of a safer alternative design, the cost of an improved design, and the adverse effects of an alternative design on the Product and the consumer, the risks of the Product's design outweighed its benefits, rendering the Product not reasonably safe. Dart v. Wiebe Mfg., Inc., 147 Ariz. 242 (1985); Golonka v. General Motors Corp., 204 Ariz. 575, 65 P.3d 956 (App. 2003).
C. Feasible Safer Alternative Design
5.6. A safer alternative design was available and feasible at the time of manufacture, consisting of [DESCRIBE THE ALTERNATIVE DESIGN], which was technically and economically practical because [the technology was available; competitors used safer designs; the cost was modest; the alternative did not impair utility — [____]].
D. Defendants' Knowledge
5.7. Defendants knew or, in the exercise of reasonable care, should have known of the design risk because [pre-market testing; prior similar incidents; consumer complaints; industry knowledge; failure to meet safety standards; internal documents — [____]]. For purposes of the risk-utility analysis, Defendants are charged with knowledge of the Product's dangerous condition under Dart's hindsight standard.
E. Plaintiff's Use and Injury
5.8. On or about [__/__/____], Plaintiff acquired the Product from [SOURCE] and used it in a manner that was intended and reasonably foreseeable.
5.9. On or about [__/__/____], while Plaintiff was using the Product as intended, [DESCRIBE THE INCIDENT] occurred as a direct and proximate result of the design defect.

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. Each Defendant was a manufacturer or seller engaged in the business of placing the Product into the stream of commerce, and the Product reached Plaintiff without substantial change in its condition.
6.3. The Product was in a defective condition and unreasonably dangerous when it left Defendants' control because of its design, as established under the consumer-expectation test, the risk-utility test, or both. Dart v. Wiebe Mfg., Inc., 147 Ariz. 242, 709 P.2d 876 (1985).
6.4. The design defect was a direct and proximate cause of Plaintiff's injuries.
6.5. As a direct and proximate result, Plaintiff has suffered damages in amounts to be proven at trial.

7.1. Plaintiff realleges and incorporates Paragraphs 1.1 through 6.5 as though fully set forth.
7.2. Defendants owed Plaintiff and other foreseeable users a duty to exercise reasonable care in the design, testing, and evaluation of the Product so that it would be reasonably safe for its intended and foreseeable uses.
7.3. Defendants breached that duty by [failing to conduct adequate pre-market testing; ignoring known design risks; failing to incorporate available safety features; failing to follow industry standards; prioritizing cost over safety; failing to account for foreseeable use — [____]].

14. ARIZONA PRACTICE NOTES
-
Both tests apply. Arizona uses BOTH the consumer-expectation test and the risk-utility test for design defect; the plaintiff may proceed under either or both. Dart v. Wiebe Mfg., Inc., 147 Ariz. 242, 709 P.2d 876 (1985); Golonka v. General Motors Corp., 204 Ariz. 575, 65 P.3d 956 (App. 2003). Plead both.
-
Hindsight risk-utility — Arizona's signature feature. Under Dart, the risk-utility balancing is conducted with hindsight: the fact-finder assumes the defendant knew of the product's dangerous condition at the time of sale, whether or not the danger was actually knowable then. This is more plaintiff-favorable than a state-of-the-art-at-time-of-manufacture standard. Note the interaction with the statutory "state of the art" defense in A.R.S. § 12-683, which can still be raised by the defendant.
-
Reasonable alternative design. A feasible safer alternative design is a central factor in the risk-utility analysis and strong evidence of defect, though Arizona has not made it a rigid, freestanding prima-facie element. Develop alternative-design evidence with a qualified expert.
-
Statute of limitations. Two years from accrual for personal-injury actions. A.R.S. § 12-542. The discovery rule may delay accrual.
-
Twelve-year statute of repose — critical screen. A.R.S. § 12-551 bars a product-liability action commenced more than twelve years after the product was first sold for use or consumption, EXCEPT where the action is based on the manufacturer's or seller's negligence or on breach of an express warranty. If the Product is over 12 years old, the strict-liability design-defect count may be time-barred while the negligent-design and express-warranty counts survive — plead and preserve those theories.
-
Comparative fault. Arizona applies pure comparative fault under A.R.S. § 12-2505: the plaintiff's recovery is reduced by the plaintiff's percentage of fault but is not barred even if the plaintiff is mostly at fault (subject to the limited exception for intentional/illegal conduct). Liability is several only, not joint, under A.R.S. § 12-2506, so fault may be apportioned to nonparties; comply with the nonparty-at-fault notice rules.
-
Punitive damages. Require clear and convincing evidence of an "evil mind." Linthicum v. Nationwide Life Ins. Co., 150 Ariz. 326 (1986). Arizona has no general statutory cap on punitive damages, but awards are subject to constitutional proportionality review.
-
Statutory defenses. A.R.S. § 12-683 codifies defenses including state of the art, unforeseeable alteration or misuse, and use contrary to instructions; anticipate these.

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.
