Selling Your Home in Quebec: The Seller's Burden of Proof

Most sellers think of documents as an end-of-process formality, something the notary will ask for. That gets the problem backwards. What matters is not the list of papers but the rule that decides who has to prove what, and when. This article is about that rule, from the seller's side. The buyer's side, proving a defect, is covered in our guide to hidden defects in Quebec.

A simple rule: whoever asserts must prove

The Civil Code of Québec sets a general rule: a person who wants to assert a right must prove the facts supporting their claim. The rule targets the seller no more than the buyer. It targets whoever puts forward a fact and wants to draw a consequence from it.

In a real estate sale, the roles are therefore split by what each side asserts. A buyer claiming a defect existed before the sale has to prove it. But a seller claiming they told the buyer about that defect, or did what they promised, has to demonstrate it in turn. The burden of proof doesn't fall on one side: it follows the assertions.

What the seller writes becomes what they must demonstrate

Throughout the transaction, the seller states things: in their declarations about the property, in the promise to purchase they accept, in their answers to the buyer's questions. Each of those statements is a commitment. Writing that the roof was redone, that work was done with a permit or that no water damage ever occurred means you may be asked to show it.

The buyer, their lender or their notary can ask for proof of what was stated, and a statement backed by nothing remains a mere claim. The practical consequence runs against intuition: for a seller, saying more is not always safer. What protects you is saying what you can prove, and saying it precisely.

Having disclosed isn't enough; you must be able to show you did

The most underestimated point is disclosure. A seller who flagged a defect to the buyer is in a strong position in a dispute, because a buyer can't complain about what they knew when buying. The seller still has to be able to establish that the information was actually passed on.

A remark made out loud during a visit leaves no trace. A mention in signed declarations, a report handed over against acknowledgment of receipt, an email between the brokers, all leave a dated one. If a disagreement surfaces months later, that record, and only that record, lets you argue that the buyer knew. A seller who said everything but can show nothing ends up where the seller who said nothing does.

Title: the seller proves they can sell

The seller also undertakes to transfer ownership free of defects. The notary examines the titles to make sure, but it is up to the seller to provide what establishes that they are indeed the owner and have the power to sell, for example when the property is held jointly or when one person signs for another.

Until that proof is in place, the notary cannot close. It isn't excessive caution on their part: it guarantees the buyer receives what they are paying for. A seller who anticipates this check keeps it from becoming the reason for a postponement.

What a missing document costs

A document you cannot provide costs in three ways, depending on what the promise to purchase says. First in time: the signing at the notary's slips until whatever is missing is resolved, with knock-on effects on the move, the financing and sometimes the seller's next purchase.

Then in negotiation: if the promise makes the sale depend on a check that the missing document prevents, the condition may go unmet, and the buyer can withdraw or ask for a concession to carry on. The seller then negotiates from weakness, at the worst moment, with the signing date close.

Finally in exposure: a statement you could never prove doesn't disappear at signing. It stays what it was, an undemonstrated commitment the buyer can raise later. Of the three costs, it is the only one that isn't visible on sale day.

Proof gets built before listing, not at the notary's

The practical takeaway comes down to two habits. Before listing, reread what you are about to declare and ask, for each statement, what would demonstrate it if someone asked. What can't be demonstrated gets worded differently, or isn't asserted.

During the transaction, keep a dated record of everything given to the buyer: what, when, through whom. Your broker can log those exchanges in the file. It takes a few minutes at each step, and it saves weeks when a question comes up at the last minute, or years when it comes up afterward.
