Legal warranty: what an exclusion actually takes away

In Quebec every seller warrants that the house is free of latent defects (vices cachés) under article 1726 of the Civil Code of Québec. The line "sold without legal warranty (garantie légale), at the buyer's own risk" removes that recourse for the quality of the property. It does not release the seller from disclosing what they know.

What the legal warranty covers

Article 1726 requires the seller to warrant that the property is, at the time of the sale, free of latent defects that make it unfit for its intended use, or that so reduce its usefulness that you would not have bought it, or not at that price, had you known. Four conditions sit in that sentence: the defect must be hidden, serious, prior to the sale, and unknown to you when you bought.

Hidden means not detectable by a prudent and diligent buyer without calling in an expert. That is why a pre-purchase inspection is not a formality: whatever a competent inspector should have seen stops being hidden.

If the seller knew of the defect or could not have been unaware of it, they owe damages on top of returning the price (art. 1728). A professional seller is held to a stricter standard still (art. 1729). And when you discover a defect you must notify the seller in writing, within a reasonable time of the discovery (art. 1739): a late notice alone can end the claim.

Two points that come up often. The warranty of quality travels with the property, which is why a claim can reach a previous owner. And the warranty of quality is not the warranty of ownership — the one that protects you against an undischarged hypothec or an encroachment is a separate warranty, untouched by the wording discussed here.

"Without legal warranty, at the buyer's own risk"

The Code lets the parties add to the warranty, reduce its effects, or exclude it entirely (art. 1732). The exclusion appears in the promise to purchase and is repeated in the notarial deed. The full formula matters: "without the legal warranty of quality, at the buyer's own risk". It is the "at the buyer's own risk" half that does the heavy lifting, because it also covers defects a non-professional seller could not have been unaware of (art. 1733).

What the exclusion does not do:

• It never covers the seller's personal acts. A seller who hid a leak behind a panel remains liable.
• It does not make a false seller's declaration (déclaration du vendeur, DV) harmless. A written lie is a personal act, not a latent defect.
• It does not touch the warranty of ownership, nor a builder's obligations under a new home warranty plan.

Where the clause shows up

Three situations produce most of them. Estates, where a liquidator who never lived in the house cannot answer for its condition. Bank repossessions (reprises de finance), where the lender never occupied the building. And sales made under judicial authority, which carry no warranty of quality.

There is a fourth, more delicate case: an ordinary owner who excludes the warranty because they know something. That is not illegal — it is exactly the question to ask.

What it changes for the inspection

Without the legal warranty, the inspection stops being a confirmation and becomes your only protection. In practice:

• Book a longer and more intrusive inspection, and accept a bigger budget than usual for it.
• Add the targeted tests the property justifies: camera in the French drain (drain français), petrographic analysis of the fill under the slab, radon test, verification of an old oil tank.
• Read the inspector's contract: their own liability is capped in it, often at the amount of their fee.
• Make the inspection a condition of the promise to purchase, with a realistic deadline and a clear right to withdraw.

What it changes for financing and price

Talk to your mortgage broker or lender before submitting the offer, and to your home insurer too: some files call for extra documents when the warranty is excluded. That question belongs at the start, not the night before the notary.

On price the logic is simple: you are buying the property and you are buying the risk. A discount often exists, but it is not automatic and there is no scale for it. The way to size it is to price the reserves your inspection reveals, then treat that amount as a certain expense in your budget rather than a possibility.

What to ask

• Why is the warranty excluded in this file?
• Did the seller live in the house, and for how many years?
• Can I have the seller's declaration (DV) completed and signed, even with the warranty excluded?
• What invoices exist for the roof, windows, foundation, drain, electrical and plumbing?
• Has there been an insurance claim, a loss, or a dispute?

FAQ

What counts as a latent defect in Quebec?

A serious defect, existing before the sale, unknown to you, that a prudent and diligent buyer could not have detected without an expert. A visible or disclosed defect is not a latent defect.

Is buying without the legal warranty dangerous?

It is a transfer of risk, not a trap. Many estates and repossessions are sold that way. The danger is buying one at the same price, and with the same inspection, as a warranted house.

Can the seller hide anything once the warranty is excluded?

No. The exclusion never covers the seller's personal acts or a false declaration. A seller who deliberately conceals a known defect stays liable.

How long do I have to report a latent defect?

The Code requires written notice to the seller within a reasonable time of discovery. Write as soon as you find it, keep proof of sending, and talk to a lawyer before starting corrective work.

Does a pre-purchase inspection replace the legal warranty?

No. It reduces the unknown; it does not create a recourse against the seller. They are two separate protections, and without the legal warranty only the first one is left.
