3.2 Delaware Seller Disclosure Requirements

The Buyer Property Protection Act

Delaware's seller disclosure regime lives in the Buyer Property Protection Act, 6 Del. C. Chapter 25, Subchapter VII. It requires a residential seller to complete the Seller's Disclosure of Real Property Condition Report, a multi-page DREC-approved form, and to deliver it on a strict timeline.

Timing — the most-tested point

The statute imposes two deadlines that the state exam loves:

• The disclosure must be made in writing before the seller signs the listing agreement.
• A copy must be given to every prospective buyer (or buyer's agent) before the buyer makes an offer to purchase.

The signed disclosure becomes part of the purchase agreement. The seller must update it for any material change occurring before final settlement. This is a disclosure of known conditions, not a warranty.

Trap: There is no general statutory 'rescission period' allowing a buyer to walk away days after signing a normal Delaware home sale. The protection is front-loaded: the buyer sees the report before offering. If a seller fails to deliver the report, the buyer's remedy runs through the Act, not a generic cooling-off right.

Known defects, not investigation

A seller must disclose all material defects known at the time the property is offered for sale or known before final settlement. Sellers are not required to hire professionals to hunt for hidden problems. Honesty about what they know is the standard.

Radon — a Delaware-specific overlay

Delaware law (24 Del. Admin. Code) layers a radon disclosure onto the transaction. The seller must disclose any known radon test results, and DREC publishes a separate Radon Disclosure/Exemption acknowledgment. Radon is a colorless radioactive gas common in Delaware soils, so the state takes it seriously even though sellers need not test. If a buyer wants certainty they negotiate a radon contingency in the Agreement of Sale (see Section 3.1). This is a frequent state-portion distinction: the seller discloses known results; the buyer arranges new testing.

What the Disclosure Covers

The Real Property Condition Report asks structured questions across several categories. Memorize the buckets.

Federal lead-based paint overlay

For any home built before 1978, the federal Residential Lead-Based Paint Hazard Reduction Act (Title X) independently requires a lead disclosure, the EPA pamphlet, and a 10-day window for the buyer to conduct a lead inspection. This federal rule stacks on top of the Delaware form.

Exempt Transfers

Certain transactions are exempt because the transferor lacks personal knowledge or the deal is supervised by a court.

What Sellers Need NOT Disclose

Delaware treats certain facts as non-material psychological stigmas that need not be disclosed:

• A death, suicide, or homicide that occurred on the property.
• A prior occupant's HIV/AIDS status (also protected under fair housing law).
• Alleged paranormal activity.

Consequences of Non-Disclosure

Knowingly concealing a material defect exposes a seller to fraud or misrepresentation claims, rescission of the contract, and damages for repair costs and legal fees. Misrepresentation and non-disclosure are leading sources of post-closing litigation, which is exactly why the Act front-loads the report before the buyer ever writes an offer.

Worked example: A seller knows the basement floods every spring but answers 'no water problems.' After closing the buyer discovers staining and an active leak. Because the defect was known and material, the buyer can pursue rescission or damages — the as-is nature of the deal does not shield deliberate concealment.

Agent's independent duty

The listing agent is not a passive bystander. A Delaware licensee who knows of a material defect must see that it is disclosed and may not help a seller conceal it; doing so risks DREC discipline and personal liability for misrepresentation. The agent is not, however, required to independently inspect the structure or verify every seller answer — the agent's duty is honesty about what is known and reasonable care, not the role of a home inspector.

As-is sales and 'caveat emptor' limits

Marketing a home 'as-is' limits the seller's promise to repair, but it does not erase the statutory duty to disclose known material defects. Delaware tempers the old rule of caveat emptor ('let the buyer beware') with the Buyer Property Protection Act: a seller cannot use 'as-is' language to bury a known leaking roof or a failing septic system. Buyers, in turn, should still arrange their own professional inspections — disclosure informs them, but it does not substitute for due diligence.
