The Kansas Product Liability Act (KPLA): A Complete Guide to Consumer Rights and Strict Liability

Current as of: October 8, 2026 Product Liability & Defective Products Kansas
Under the Kansas Product Liability Act, you can hold a manufacturer legally accountable for selling a dangerously defective product without having to prove they intended to cause harm. Filing a civil lawsuit in a Kansas district court generally requires a standard filing fee of around $195.

Understanding the Kansas Product Liability Act (KPLA)

When you buy a tool, an appliance, or a medical device, you expect it to function safely. Unfortunately, dangerous and defective products injure thousands of Americans every year. In this state, consumers are protected by the Kansas Product Liability Act (KPLA), codified under Kan. Stat. Ann. § 60-3301 et seq. This comprehensive legal framework dictates how injury claims against product manufacturers and sellers are handled in local courts, from Wichita to Overland Park.

A crucial distinction of the KPLA is that it applies exclusively to the manufacturers and sellers of tangible physical products. It does not apply to service providers. For instance, if an electrician wires your house incorrectly, that is a negligence claim based on a service. But if the wire itself was manufactured with a dangerous flaw that caused a fire, that falls squarely under the Kansas Product Liability Act. Finding an experienced lawyer in our directory is the first step to navigating these complex statutes.

The Three Main Types of Product Defects

To win a product liability claim under the KPLA, you and your attorney must prove that the product was legally 'defective.' Kansas law recognizes three primary categories of defects.

Manufacturing Defects

A manufacturing defect occurs when a mistake is made during the actual assembly or production of the item. The product's design might be perfectly safe, but a specific batch was ruined on the assembly line. For example, if a bicycle's frame cracks because the factory used substandard welding on a few units, those specific bicycles have a manufacturing defect.

Design Defects

Unlike a manufacturing flaw, a design defect means the product was built exactly as intended, but the original blueprint was inherently dangerous. For example, an SUV designed with a center of gravity so high that it easily rolls over at low speeds has a design defect. To prove this in Kansas, you generally must show that a 'reasonable alternative design' existed that was safer, economically feasible, and practical.

Failure to Warn (Marketing Defects)

Some products are inherently dangerous but still useful (like chainsaws or prescription drugs). In these cases, the manufacturer has a legal duty to provide adequate instructions and warning labels. If a drug company fails to warn doctors and patients about a severe side effect, or a power tool lacks a warning label about a hidden moving part, you can sue for a failure to warn. Case law like Savina v. Sterling Drug, Inc., 247 Kan. 105 (KS Supreme Court 1990) heavily shapes how failure to warn is evaluated regarding pharmaceuticals.

Strict Liability vs. Negligence in Kansas

The KPLA simplifies the burden of proof for injured consumers through the doctrine of 'strict liability.' In a standard negligence case (like a car crash), you must prove that the other person acted carelessly or unreasonably. In a strict product liability case, you do not have to prove the manufacturer was careless.

Instead, your burden of proof requires showing three things: 1) The product was defective when it left the manufacturer's control, 2) You used the product in a reasonably foreseeable manner, and 3) The defect directly caused your injury. Even if the manufacturer exercised extreme caution during production, they can still be held strictly liable if a defective product slips through and hurts you.

How Comparative Fault Works Under Kansas Law

Manufacturers rarely admit fault. Instead, defense attorneys will argue that you caused your own injury by misusing the product or ignoring warning labels. This brings the Kansas comparative fault rule into play, outlined in Kan. Stat. Ann. § 60-258a. Kansas operates on a 'less than 50%' modified comparative fault system.

This means you can still recover compensation as long as you are 49% or less at fault for your injuries. If a jury determines you were 20% at fault for using a tool incorrectly, your final settlement will be reduced by 20%. However, if the jury finds you 50% or more at fault, you are completely barred from recovering any money. Because of this harsh cutoff, having a skilled attorney to defend your actions is critical.

Step-by-Step Process to File a Claim

Filing a lawsuit against a massive corporation requires precision and strict adherence to Kansas civil procedure.

Step 1: Preserve the Defective Product

The most important step is keeping the product exactly as it was after the injury. Do not throw it away, repair it, or return it to the manufacturer. Without the physical product, it is almost impossible for engineering experts to prove the defect existed.

Step 2: Draft and File the Petition

Your legal team will draft a formal complaint detailing the strict liability allegations. This document is typically filed at a local courthouse, such as the Johnson County District Court, Olathe or the Sedgwick County District Court, Wichita, often utilizing a Form Civil Cover Sheet, Kansas, Judicial Council, Civil Cover Sheet.

Step 3: Discovery and Expert Testimony

Because product liability cases are highly technical, your attorney will hire biomechanical engineers, medical experts, or industry specialists to inspect the product and testify on your behalf to meet your burden of proof against the defense's own highly-paid experts.

Frequently Asked Questions (FAQ)

What is the Kansas Product Liability Act?

The KPLA is a set of state laws that governs all injury claims arising from defective products, standardizing the rules for strict liability and manufacturer defenses.

Can I sue the retail store that sold me the defective item?

Under the KPLA, non-manufacturing sellers (like retail stores) are generally protected from strict liability unless they actually altered the product, or if the manufacturer cannot be sued because they are bankrupt or located overseas.

Do I have to prove the manufacturer was careless?

No. Under strict liability, you only need to prove that the product was defective and unreasonably dangerous when it left their control, and that the defect caused your injury.

What if I lost the instructions before using the product?

The defense may argue you are comparatively at fault. However, if the product lacked crucial safety guards (a design defect), you may still have a strong case regardless of the instructions.

Where are product liability cases filed in Kansas City?

Lawsuits in that specific jurisdiction are typically filed in the Wyandotte County District Court, Kansas City.
