Key takeaways
  • A latent defect is one a reasonable inspection would not reveal, while a patent defect is one a buyer could see for themselves.
  • A licensee acting for a seller must promptly disclose known material latent defects before any agreement is entered into.
  • A material latent defect includes dangerous conditions, very costly defects, notices from local government and missing permits.

You may know your home has a past leak, some rot or an earlier pest problem and wonder whether you have to say so. The answer depends partly on whether the problem is something a buyer could see, or something hidden.

This article explains the two terms in plain words and sets out what the Real Estate Services Rules say about hidden defects in British Columbia. It does not replace advice on your own situation.

This article covers the law of British Columbia.

Patent and latent: the plain-words difference

A patent defect is obvious or easy to find. A cracked window or a stained ceiling in plain view are examples. A latent defect is hidden, and a reasonable inspection would not uncover it.

The Rules use the phrase material latent defect and define it as a material defect that cannot be discerned through a reasonable inspection of the property. The line between the two is not always clear, and it can depend on what a reasonable inspection would have found.

What counts as a material latent defect

The definition expressly includes several situations:

So hidden rot behind a wall, a concealed leak causing damage, or unpermitted work could fall within the definition depending on the facts. A past pest issue that was fully dealt with is a different question, and it is worth asking a lawyer how it should be handled.

What your licensee must do

A licensee acting for a seller must promptly, and before any agreement for the acquisition or disposition is entered into, disclose known material latent defects to all other parties to the trade. The duty is about defects that are known, and it comes before the contract is signed.

If you instruct the licensee not to disclose such a defect, the licensee must refuse to provide further trading services to you for that trade.

The licensee does not have to disclose a defect to a party who has already received written disclosure of that defect from the selling client. Giving the buyer clear written disclosure yourself can therefore matter.

Separately, before providing trading services, a licensee must disclose, in the approved form, whether they will represent the party as a client. It is a good moment to ask your licensee how they handle defect questions.

Visible problems and the limits of what is covered here

The licensee duty above is about material latent defects. It does not by itself settle every question about visible problems, what goes on a property disclosure form, or what a court may decide in a dispute. Those depend on the facts, the contract and the law at the time, and a lawyer can confirm them.

Time limits if a buyer later says something was hidden

Problems can come to light after a sale closes, and a buyer who believes something was concealed may consider a claim. Whether a claim would succeed depends on the facts, and a lawyer can confirm how the law applies.

A court proceeding generally must not be commenced more than 2 years after the day the claim is discovered. Discovery is when the person knew or reasonably ought to have known that loss occurred, who caused it, and that a court proceeding is appropriate.

There is also an ultimate limitation period of 15 years from the act or omission. If the defendant wilfully conceals the claim or misleads the claimant, the act or omission is treated as occurring on the discovery date instead.

This is one reason clear records matter. If you can show what you knew, what you repaired and what you told the buyer in writing, any later discussion about what was disclosed is far easier to sort out.

What to do before you sell

If a problem is borderline, do not guess. Bring your records to a lawyer before you list so that you know how to describe it.

Frequently asked questions

Do I have to disclose a leak that I repaired?

The duty applies to known material latent defects. Whether a repaired leak qualifies depends on the facts, such as cost, danger and whether the problem is still present, so ask a lawyer.

What if the defect is dangerous?

A defect that makes the real estate dangerous or potentially dangerous to occupants can be a material latent defect, but only if it is a material defect that cannot be discerned through a reasonable inspection of the property. If it is one and it is known, your licensee must promptly disclose it to all other parties to the trade before any agreement is entered into. Whether a particular dangerous condition meets that test depends on the facts, so it is worth confirming with a lawyer.

Can I tell my agent to keep quiet?

If you do, the licensee must refuse to provide further trading services to you for that trade. A licensee also need not disclose a defect to a party who has already received written disclosure of it from the selling client.

Is missing permit work a defect?

A lack of appropriate municipal building and other permits is listed in the definition. Confirm how it applies to your home with a lawyer.
