The Seller’s Disclosure in Kansas City: What Sellers Have to Share, and What Buyers Should Read Twice

Every house has a few secrets. The roof that leaked once in 2019. The basement corner that gets damp when it really pours. The breaker that trips if you run the microwave and the hair dryer at the same time.

The seller’s disclosure is where the house confesses. If you are selling, it protects you. If you are buying, it is the best free information you will get about a home. Here is how it works on both sides of the state line.

What a seller’s disclosure actually is

It is a written form where the seller answers questions about the home’s condition and history. The Missouri REALTORS form runs about six pages, with yes-or-no questions in 19 categories and space to explain. Kansas has its own REALTOR form.

Expect questions about the roof, foundation, basement water, plumbing, electrical, heating and cooling, pests, environmental issues, HOA dues and past repairs.

It is not an inspection and it is not a warranty. It is the seller telling you what they know.

Is it required in Missouri?

The standard form itself is not required by law. What the seller must disclose is a different story.

• Known material defects. Missouri’s consumer protection law bars concealing material facts in a sale, so sellers are expected to share defects they know about.
• Meth production. Sellers must disclose in writing if they know the home was used to make methamphetamine.
• Waste disposal sites. Any solid waste disposal site or demolition landfill on the property must be disclosed.
• What sellers may leave out. Missouri lets sellers stay silent on “psychological impacts,” such as a death or crime that happened in the home.

Agents have their own duty. A Missouri licensee must disclose adverse material facts they know or should have known about.

Is it required in Kansas?

Kansas also has no mandatory form. But under Kansas law, sellers and their agents must disclose adverse material facts the seller actually knows, including the property’s physical condition, environmental hazards and title problems.

Kansas contracts also carry specific language about radon, the sex offender registry, and any special assessments owed on the property.

On both sides: lead paint

If the home was built before 1978, federal law applies everywhere. Sellers must disclose any known lead-based paint, hand over the EPA lead pamphlet, and give buyers a chance to test for lead.

“Can’t I just sell it as is?”

You can. Locally, that is often done with an “In Its Present Condition” addendum. But “as is” means “I’m not fixing things.” It does not mean “I’m not telling you things.” Hiding a known problem can still lead to a lawsuit for fraud.

If you are selling: four tips

1. When in doubt, disclose. A buyer who knew about the old leak cannot easily claim surprise later.
2. Attach receipts. “Basement waterproofed in 2022, transferable warranty attached” turns a red flag into a selling point.
3. Keep it current. In the local contract, your disclosure must be accurate as of the day the contract is signed. New leak last week? Update it.
4. Consider a pre-listing inspection. No surprises for you, fewer renegotiations later.

If you are buying: read it twice

Read it once for what it says, then again for what it skips.

• Count the “unknown” answers. A few are normal for a long-time owner or an estate sale. A form full of them is a cue to ask questions.
• Look for water. Basements, sump pumps, grading and gutters. Water is one of the costliest surprises in this area.
• Note every repair. Then ask your inspector to look hard at each one.
• Get your own inspection anyway. The seller can only tell you what they know.

Common questions

Do sellers in Missouri have to fill out a disclosure form?
No law requires the standard form, but sellers are expected to disclose known material defects, and specific items like past meth production must be disclosed in writing.

Do I have to disclose a death in the home?
In Missouri, sellers may stay silent about psychological impacts such as a death or crime in the home. Talk to your agent or an attorney about your situation.

Does “as is” mean the seller can hide problems?
No. Selling as is means the seller will not make repairs. It does not excuse hiding known defects.
