Prescription Acquisitive Decennial: Beware of Old Fences!
Acquisitive prescription in Quebec allows land to be acquired after 10 years of uncontested occupation. Protect your property boundaries.

Acquisitive prescription is a little-known concept in the Civil Code of Quebec that can have a significant impact on property owners. Under article 2910 of the Civil Code, a person may become the owner of real property by continuous, peaceful, public and unequivocal possession for a period of 10 years. A recent Quebec Superior Court ruling (2023 QCCS 3076) perfectly illustrates this reality, and warns of the possible consequences of negligence in managing property boundaries.
A Property Dispute Resolved by Prescription
In this case, an owner contested the occupation of a parcel of his land by a neighbor for over ten years. The Court concluded that, since the occupier had used the parcel without interruption, without opposition and in a visible manner, he became the legal owner by acquisitive prescription. This decision confirms that simple inaction on the part of the original owner can lead to the loss of rights to a portion of his land.
Implications for homeowners
Landowners, especially in urban areas like Montreal, need to be particularly vigilant when it comes to this legal rule, especially when old fences mark the boundaries of properties. Here are a few recommendations to avoid unpleasant surprises:
- Check your property limits: Consulting a land surveyor to confirm the legal limits of your property is a wise investment.
- Monitor land use: If a neighbor is using a portion of your property without your permission, address the situation immediately. A simple written notice may be enough to interrupt the prescription period.
- Don't delay: When in doubt, consult a real estate lawyer to assess your options and prevent prolonged occupation from becoming an involuntary transfer of ownership.
Ten-year acquisitive prescription is a powerful mechanism in Quebec law that can have a major impact on land ownership. Proactive management of property boundaries is essential to protect your real estate assets.
