How to Contest a Hidden Defect After Purchase

First Step: Don't Touch Anything

Many homeowners' first instinct upon discovering a serious problem is to fix it right away. That's a mistake if you're considering legal action: any intervention before an expert assessment risks destroying evidence of the defect, its severity, and its origin. Wait for a professional to document the situation before undertaking anything, except in emergencies to prevent damage from worsening.

If you're not yet familiar with your full rights as a buyer, our article on hidden defect buyer rights in Quebec lays out the applicable legal framework.

Document the Defect with an Independent Expert Report

Have a hidden defect expertise on the South Shore or elsewhere in the region carried out by a professional with no connection to the seller, the agent, or the original pre-purchase inspector. The report must clearly establish the nature of the defect, its severity, that it predates the sale, and the cost of repairs. This report becomes the cornerstone of your case.

Send a Formal Notice

Once the defect is documented, you must notify the seller in writing, typically through a lawyer, describing the defect and demanding compensation within a specific timeframe. This step, called a formal notice, is a mandatory prerequisite before any lawsuit and must be sent within a reasonable time after discovering the defect.

Your Possible Remedies

Why an Initial Inspection Changes Everything

The strongest cases often rest on comparing a residential inspection done before the purchase against the post-sale expert report: it demonstrates that the defect could not have been detected at the time of the transaction. This underscores the importance of always having a property inspected before buying, whether in Brossard or elsewhere in the region.

Who Pays for the Expert Report, and Can It Be Recovered

The buyer generally covers the initial cost of the expert report, but that amount can be claimed back from the seller as part of the legal action, along with reasonable legal fees and repair costs, if the court or the settlement recognizes the seller's liability. That's one more reason to choose an expert whose report will be seen as credible and well documented.

Choosing the Right Expert

Favor a professional with recognized experience in real estate disputes who has previously testified in court, where relevant. A report written to meet legal requirements, with a clear methodology and references to applicable standards, carries far more weight than a simple technical opinion.

A Hidden Defect Discovered Years After Purchase

The three-year deadline runs from the moment the defect is discovered, not from the purchase date. It's therefore not unusual for a structural problem to surface five, ten, or even fifteen years after the transaction, such as a slow-developing pyrite issue. In these cases, the expert report must not only establish the nature of the defect but also demonstrate, often using historical data or specialized analysis methods, that it already existed at the time of sale.
