Purchasing property is a major milestone in anyone's life. To secure this investment and protect your rights as a buyer, it is essential to understand the legal warranties, remedies for latent defects, and best practices to follow when acquiring real estate in Quebec.

The Legal Warranties: Essential Protection

In Quebec, the law provides buyers with protection called the “legal warranty of quality.” This warranty ensures that the sold property is free of latent defects that would make it unsuitable for its intended use or would significantly diminish its usefulness to such a degree that the buyer would not have purchased it, or would not have paid as high a price, if they had known about them.

What is a latent defect?

A latent defect is a defect not apparent at the time of purchase, that existed before the sale and was not known by the buyer. For a defect to be considered latent, it must meet the following criteria:

  • Gravity: The defect must be serious enough to render the property unfit for normal use or diminish its usefulness so much that the buyer would not have purchased it, or would not have paid as high a price, if they had known about it.
  • Non-appearance: The defect was not visible during a reasonable inspection by a prudent buyer, without expert assistance.
  • Antériority: The defect existed at the time of the sale.
  • Ignorance: The defect was unknown to the buyer at the time of the sale.

Remedies for latent defects

If you discover a latent defect after the purchase, several remedies are available to you:

  • Price reduction: Request a reduction in the sale price proportional to the cost of necessary repairs.
  • Reimbursement of work: Demand reimbursement of expenses incurred to remedy the defect.
  • Rescission of the sale: In some cases, seek rescission of the sale and full reimbursement of the price paid.

It is important to notify the seller in writing as soon as the defect is discovered, and this within a reasonable period, generally six to twelve months.

Practical tips to protect your interests

To minimize risks when purchasing a property, here are some tips:

  • Pre-purchase inspection: Hire a qualified building inspector to assess the overall condition of the property.
  • Seller’s disclosure: Require a complete disclosure from the seller regarding the condition of the building.
  • Verification of documents: Review legal documents, such as the certificate of location, to verify the absence of undisclosed easements or mortgages.
  • Title insurance: Consider taking out title insurance to protect yourself against title defects or legal issues related to the property.

Concrete examples

Imagine that, a few months after purchasing your home, you discover water intrusion in the basement, causing significant damage. If these intrusions were present before the sale and not apparent during the inspection, they could be considered latent defects. In this case, you could:

  • Contact the seller to inform them of the problem and negotiate compensation or a price reduction.
  • If the seller refuses to cooperate, consider legal remedies to obtain redress.

Another example: during the purchase, you notice minor cracks in the walls, but after a few months these cracks worsen, revealing underlying structural problems. If these problems were present before the sale and not detectable during the inspection, they could constitute a latent defect, opening the door to similar remedies.
