What triggers the duty

  • No statutory disclosure trigger. A seller's/licensee's duty arises only when there is a known material defect that cannot be concealed or misrepresented (common law / Missouri Merchandising Practices Act). Use of the Missouri REALTORS Seller's Disclosure Statement is voluntary/customary, not statutorily mandated.

Penalties & remedies

Not specified by statute (no disclosure statute). Active concealment or misrepresentation of a known material defect can expose a seller to common-law fraud/misrepresentation liability and claims under the Missouri Merchandising Practices Act (RSMo Ch. 407); real estate licensees are separately subject to discipline by the Missouri Real Estate Commission.

Buyer remedy: Varies. No statutory disclosure remedy; buyer may pursue common-law fraud/negligent misrepresentation or a Missouri Merchandising Practices Act claim (which can allow actual damages, and in some cases attorney's fees/punitive damages) where a known material defect was concealed or misrepresented.

Opt-out gotchas

No statutory opt-out or waiver-for-credit mechanism identified. The disclosure duty (where it exists) cannot simply be bought out.

Verified that Missouri has NO statute mandating a seller property-condition or flood disclosure form. The Missouri Real Estate Commission requires brokers to provide a broker-relationship disclosure (20 CSR 2250-8.097) and licensees may not misrepresent or conceal known material facts, but neither imposes a seller flood-disclosure duty. statute_citation=null because no statute imposes the disclosure duty. source_url (RSMo 339.730, the broker-relationship disclosure statute) is the closest primary on-point provision; the operative fact (absence of a mandatory seller disclosure statute) is a negative confirmed across multiple sources.

Buyer's rights

If you're buying in Missouri

Your rights re-framed from the buyer's side, plus a pre-closing checklist that holds in every state.

What Missouri law gives you as a buyer

Missouri does not mandate a seller flood-disclosure form, so the steps below matter even more here. You generally still have a claim if the seller actively concealed a known defect or answered a direct question falsely — but the burden is on you to ask and to investigate.

Your pre-closing checklist (works in every state)

  • Pull a free FEMA flood-zone lookup

    Enter the address on FEMA's Flood Map Service Center to see the property's flood-zone designation (Special Flood Hazard Area = Zone A/V). This is public and free, regardless of what the seller discloses.

  • Request a CLUE / loss-history report

    A C.L.U.E. (Comprehensive Loss Underwriting Exchange) report shows insurance claims filed on the property in the last ~7 years, including water and flood claims. The current owner can pull theirs free once a year from LexisNexis.

  • Get an independent inspection — ask about water

    Hire your own inspector and specifically flag drainage, grading, sump pumps, and signs of past water intrusion (staining, efflorescence, fresh paint in basements). An inspection contingency protects you if problems surface.

  • Get a flood-insurance quote before you waive contingencies

    Quote NFIP or private flood coverage early. Homeowners' insurance does NOT cover flood damage. A federally backed mortgage on a property in a Special Flood Hazard Area generally requires flood insurance — budget for it.
