Can You Sue a Real Estate Agent for Negligence or Non-Disclosure in Missouri?

Purchasing a home is usually the largest financial investment of a person's life. You rely heavily on your real estate agent to guide you, negotiate fairly, and most importantly, tell you the truth about the property. But what happens when you move into your new Missouri home and discover that the basement floods every spring, the square footage was wildly exaggerated, or your agent was secretly working in the seller's best interest?

In Missouri, real estate brokers and agents are held to strict professional and ethical standards. If an agent intentionally hides a known material defect or acts negligently in their duties, they can be held financially liable. Buyers in cities like Liberty, Jefferson City, and Joplin have robust legal protections to sue bad actors and recover their financial losses.

This guide explains the laws governing broker liability, how to leverage the Missouri Merchandising Practices Act (MMPA), and the step-by-step process of holding a negligent real estate agent accountable.

Understanding the Missouri Merchandising Practices Act (MMPA)

One of the most powerful tools a buyer has is the Missouri Merchandising Practices Act, found under Mo. Rev. Stat. § 407.020. This law prohibits deception, fraud, false pretenses, and the concealment or omission of any material fact in connection with the sale of real estate.

The landmark case Hess v. Chase Manhattan Bank, USA, N.A., 220 S.W.3d 758 (MO Supreme Court 2007) established that a seller (and by extension, their agents) can be held liable for fraud if they actively conceal a material defect that the buyer could not have reasonably discovered. Because the MMPA allows successful plaintiffs to recover their attorney fees and punitive damages, it is a highly effective statute for real estate lawsuits.

Step-by-Step Process to Sue an Agent

Filing a lawsuit against an agent requires substantial proof. Follow these steps to build a solid case.

Step 1: Review the Seller's Disclosure

Examine the written Seller's Disclosure Statement. Did the seller or the agent mark "No" on questions about previous flooding or foundation repairs? If you can prove the agent knew about the defect-perhaps because they represented the seller when a previous buyer backed out due to an inspection-you have grounds for non-disclosure.

Step 2: File a Regulatory Complaint

Before or during your lawsuit, you should file a formal complaint using Form MO 375-0652, Missouri, Missouri Real Estate Commission, Sworn Statement of Complaint. Submit this to the Missouri Real Estate Commission, Jefferson City. While the commission cannot force the agent to pay you damages, they can investigate and suspend the agent's license, which adds massive leverage to your civil case.

Step 3: File a Civil Lawsuit

Your attorney will draft a lawsuit alleging Negligence, Fraudulent Misrepresentation, or an MMPA violation. You will file this at your local courthouse, such as the Clay County Circuit Court, Liberty or the Cole County Circuit Court, Jefferson City.

Failing to Disclose Known Material Defects

A material defect is any issue that would significantly impact the value of the home or the buyer's decision to purchase it. Previous flooding, toxic mold, unpermitted structural additions, and major termite damage are prime examples. If the listing agent knew about the flooded basement but threw away a previous inspection report and painted over the water lines to help close the deal, they have committed actionable fraud.

Misrepresenting Property Square Footage

Square footage dictates a home's value. If an agent markets a home as having 3,000 square feet, but the appraisal later shows it only has 2,200 square feet, the buyer is paying a massive, unjustified premium. If the agent pulled the numbers out of thin air or willfully ignored county tax records, you can sue them for professional negligence to recover the difference in the property's actual market value.

Dual Agency Conflicts of Interest

In Missouri, it is legal for an agent to represent both the buyer and the seller in the same transaction, known as dual agency. However, under Mo. Rev. Stat. § 339.750, the agent must obtain written consent from both parties and must remain completely neutral. If a dual agent pushes a buyer to bid higher just to benefit the seller (and increase their own commission), they have breached their fiduciary duty and caused financial harm to the buyer.

Burden of Proof and Potential Damages

To win a negligence or non-disclosure case, you must prove four things: duty, breach, causation, and damages. You must show the agent had a duty to disclose, failed to do so, and that this specific failure cost you money. If successful, courts can award compensatory damages (the cost to fix the defect or the lost home value). Under the MMPA, you may also be awarded attorney fees and punitive damages to punish the agent's malicious behavior.

How Long Do You Have to File a Claim?

Under Mo. Rev. Stat. § 516.120, Missouri has a 5-year statute of limitations for negligence, fraud, and MMPA claims. The clock generally starts ticking on the day you discover (or reasonably should have discovered) the defect or the agent's deception. Do not wait to seek legal counsel, as evidence disappears quickly.

How Much Does it Cost in Missouri?

• Court Filing Fees: Filing a civil complaint in Circuit Court is generally $150 to $200.
• Attorney Fees: Most real estate attorneys charge hourly rates of $250 to $450. Some attorneys may take strong MMPA cases on a contingency basis, meaning they take a percentage of the settlement, because the law allows them to recover fees directly from the defendant.
