If you’re buying or selling a home in Montreal, the West Island, or anywhere in Quebec, one phrase should be on your radar before you sign anything: legal warranty — or more specifically, whether the property comes with one or without one.
This isn’t fine print. It’s a fundamental difference in what you’re buying — or what you’re on the hook for. And most buyers don’t fully understand it until there’s a problem.
Whether you’re a first-time buyer navigating Montreal’s market or an experienced investor, here’s what you need to know about legal warranty in Quebec real estate, what it means when a property is sold without one, and how to protect yourself either way.
The legal warranty (garantie légale) is a protection built directly into Quebec law. It applies automatically to every real estate transaction in the province unless the parties explicitly agree, in writing, to exclude it.
It’s governed by the Civil Code of Quebec, Article 1726, which requires a seller to warrant that the property is free of hidden defects (vices cachés) — defects that would have led the buyer to not purchase the property, or to purchase it at a lower price, had they known about them.
Article 1733 makes clear that this protection is the default. You don’t have to negotiate for it. It’s there unless someone takes it away.
The legal warranty has two distinct components:
The seller guarantees that they actually own the property and have the right to sell it. No hidden liens, no undisclosed mortgages, no third-party claims that could interfere with your ownership after closing. This part of the warranty protects you from title surprises.
This is the one most people think of when they hear “hidden defects.” The seller guarantees that the property is free of latent defects — problems that exist at the time of sale, aren’t visible during a reasonable inspection, and that significantly affect the property’s use or value.
Classic examples: foundation cracking hidden beneath a finished basement, a roof that was repaired cosmetically but never properly fixed, a drainage problem that only shows up during spring melt, or pyrite in the concrete slab. These are problems a regular buyer wouldn’t find during a walkthrough — and that’s exactly what the legal warranty protects against.
If a hidden defect surfaces after closing, the buyer can sue the seller. The remedy depends on the severity: it might be a price reduction, reimbursement for repairs, or in serious cases, rescission of the sale entirely.
When a property is sold without legal warranty, at the buyer’s own risk and peril (sans garantie légale, aux risques et périls de l’acheteur), that phrase must appear explicitly in the promise to purchase (promesse d’achat). It’s not implied. It’s not a checkbox. It’s a legally specific exclusion.
What it means in practice: if you buy a property without legal warranty and discover a major defect after closing — cracked foundation, water infiltration, hidden mold, faulty electrical — you cannot sue the seller for it. The risk transfers to you completely.
This is a significant exposure. Major hidden defects in Quebec can easily run $30,000 to $100,000+ in repairs. Without a warranty, that’s your problem, not the seller’s.
There’s one important nuance: the 2022 Quebec Court of Appeal ruled that if a property has ever been sold “at the buyer’s own risk and peril” in its chain of title — even by a previous owner, years ago — that prior sale effectively resets all warranties from that point forward. This means you may be buying a property with a compromised warranty history without even knowing it, which is why your notary’s title search matters enormously.
No-warranty sales aren’t random. They happen in specific circumstances — and once you know them, you’ll recognize them instantly.
Estate sales. When someone dies and heirs are selling the property, the executors often genuinely don’t know the property’s history. Was there ever a leak? Was the electrical updated? Was there a crack repaired 15 years ago? They can’t warrant something they don’t know. Estate sales are the most common no-warranty scenario in Quebec.
Bank repossessions and power of sale. When a lender takes back a property, they’re not in the business of knowing its condition. They sell it as-is, without warranty.
Investor dispositions. Older investors selling rental properties they’ve held for decades sometimes prefer to exit cleanly, without the tail risk of a hidden defect claim arising after the sale.
Pandemic-era bidding wars (2019–2022). This one is less intuitive. During the extreme seller’s market of that period, some buyers waived the legal warranty as part of a competitive offer — essentially offering the seller a guarantee-free exit in exchange for having their offer accepted. This practice has largely faded as the market normalized, but the properties sold that way are still out there in the resale pool.
Let’s be direct: buying without a legal warranty is a real risk. It doesn’t mean you shouldn’t do it — sometimes the deal still makes sense — but you need to go in with eyes wide open.
You can’t sue for defects you didn’t know about. The moment you sign “at buyer’s own risk,” you’ve accepted the property in whatever condition it’s actually in. If you find rotting floor joists after closing, that’s yours to fix.
The chain of title matters. As the 2022 Court of Appeal ruling confirmed, even if you’re buying with a warranty, a prior no-warranty sale in the title chain may have already severed your protection. Your notary should flag this.
The inspection becomes non-negotiable. Without a warranty, a pre-purchase inspection isn’t a nice-to-have — it’s your primary line of defense. You need a thorough, qualified building inspector (inspecteur en bâtiment) going through everything. Don’t cut corners here.
The certificate of location matters too. As part of your due diligence on any no-warranty property, make sure the certificate of location is current and accurate. Boundary issues, encroachments, or non-conformities with municipal regulations won’t be covered under any warranty — and are exactly the kind of thing that surfaces when a title search is done thoroughly.
There is one exception. If you can prove the seller knew about a defect and deliberately concealed it — that’s fraud, and the courts treat it differently. Bad faith voids the protection the seller gets from the warranty exclusion. But proving bad faith is hard and expensive. Don’t rely on this as your safety net.
Buying without a warranty doesn’t mean buying blind. Several protections remain in place:
The seller’s declaration (déclaration du vendeur) is still mandatory. Even in a no-warranty sale, the seller must fill out and sign a declaration disclosing known issues with the property. If they lie on it and you later prove they knew about a defect, you can still pursue legal action — the warranty exclusion doesn’t protect a fraudulent seller.
Pre-purchase inspection (inspection préachat). Non-negotiable. Hire a licensed inspector. Attend the inspection. Ask questions. Get the full written report before you waive your conditions.
Notary title search. Your notary will trace the chain of title and flag any prior “at buyer’s own risk” sales, outstanding liens, or encumbrances. This is your ownership protection, independent of the quality warranty.
Title insurance. Available through most lenders and separately, title insurance covers ownership-related risks — undisclosed liens, fraud, title defects. It does not cover physical defects in the property itself, but it fills an important gap on the ownership side.

No warranty = negotiating leverage. Use it.
No-warranty properties carry real risk, and the market generally prices that in. In practice, a no-warranty property will sell at a 5 to 15% discount compared to a comparable property sold with full legal warranty. That’s not a hard rule — it depends on the property, the condition, the neighborhood, and the motivation of the seller — but it’s a reasonable benchmark.
Here’s how to approach it:
Start lower than you would on a with-warranty property. You’re absorbing risk. That risk has a dollar value. Factor in worst-case repair scenarios from the inspection and price accordingly.
Use the inspection to negotiate further. Even if you’ve agreed to buy “as-is,” inspection findings can and should inform your final offer price or any price adjustment request. A good agent knows how to use inspection results as leverage without blowing up the deal.
Budget for unknowns. After closing, no-warranty properties may reveal surprises. Set aside a contingency reserve — at minimum, 3–5% of the purchase price — specifically for post-closing discoveries.
Don’t let a hot property make you sloppy. Even in competitive situations, the math still has to work. A great deal on a no-warranty property is still a great deal. A terrible deal on a no-warranty property with hidden problems can become a financial disaster.
Sellers don’t exclude the warranty to be devious — usually, there’s a practical reason.
Executors of estates genuinely don’t have the knowledge to stand behind a warranty. They may have never lived in the property and can’t represent its condition. Courts and OACIQ both recognize this as a legitimate reason.
Investors and long-term landlords may prefer a clean exit. If a rental property has been tenanted for 20 years and the seller hasn’t done a deep inspection in a decade, they may not want the tail risk of a hidden defect claim surfacing two years after closing.
The rules for sellers are clear:

Q: If I buy a property with legal warranty and find a hidden defect, what do I do?
Act quickly. You must notify the seller in writing as soon as you discover the defect — do not do repairs first, as this can compromise your claim. Consult a lawyer or notary and, if needed, get an expert’s report on the defect. The Civil Code gives you recourse for reimbursement, price reduction, or in extreme cases, cancellation of the sale.
Q: Can I waive the legal warranty even if the seller isn’t asking me to?
Technically yes — a buyer can choose to purchase without warranty if they wish. In practice, this is rare and generally not advisable unless you’re an investor making a calculated decision with full due diligence.
Q: Does a pre-purchase inspection replace the legal warranty?
No. An inspection identifies visible issues at the time of inspection. The legal warranty covers latent defects — problems that weren’t visible or discoverable at the time of sale. They serve different purposes. Do both when you can.
Q: What happens if the seller didn’t know about the defect — are they still liable?
Yes, in most cases. The legal warranty covers hidden defects even if the seller was unaware of them. The seller doesn’t need to have known — they warrant the property’s condition regardless. This is a key reason many estate executors choose to sell without warranty.
Legal warranty in Quebec real estate is one of those topics that seems like background noise — until it isn’t. A hidden defect claim can cost tens of thousands of dollars and years of stress. A poorly negotiated no-warranty purchase can turn a good deal into a money pit.
The rules exist to protect buyers. Understanding them protects you.
