What is the right of preemption in real estate?

🏡 You may have already heard of the right of preemption without truly knowing what it means. Yet, this clause can have a major impact on a real estate transaction, especially when a property is owned in joint ownership.

In this article, I simply explain what the right of preemption is, what it is for, and why it is important to know before buying or selling a building.


The right of preemption, what is it?

The right of preemption is a priority right to purchase.

In other words, a person or group of people may have the right to buy a property before it is sold to an external buyer, provided they meet the same conditions as the accepted offer.

⚠️ It is therefore not a discount nor a privilege allowing to negotiate a better price.

The holder of the right must buy under the same conditions as those provided in the purchase agreement.


In what situations do we find a right of preemption?

This type of clause is found mainly in certain very specific situations.

For example :

✅ a partnership agreement among co-owners;

✅ certain real estate partnerships;

✅ agreements between co-heirs;

✅ certain private agreements between owners.

However, the most common situation remains joint ownership, where several people own the same property together.


A concrete example

Let’s imagine a duplex owned by four co-owners, each holding 25% of the building.

After putting the property up for sale, they accept an offer of $600,000.

Everything seems settled...

But their joint ownership agreement contains a clause of right of preemption.

One of the four co-owners then decides to exercise this right.

He buys back the shares of the other three under the same conditions as the accepted offer.

Result?

The external buyer will ultimately not be able to acquire the building.

The transaction changes direction completely.


Why does this clause exist?

The right of preemption is mainly intended to protect certain legitimate interests.

It allows in particular :

🏡 to maintain control over the property;

🤝 to prevent a stranger from becoming a co-owner;

📋 to respect agreements made between owners;

🔒 to preserve the stability of a joint ownership.


Is this clause common?

It is not present in all real estate transactions.

However, when a property is held in joint ownership, it is highly recommended to check the agreement to see if a right of preemption exists.

It is a detail that can completely alter the course of a transaction.


What to remember

The right of preemption grants a priority to buy, but does not allow you to obtain a better price.

The person exercising this right must comply with the same conditions as the initial buyer.

That is why this clause always deserves analysis before considering a transaction as definitively concluded.
