The confidentiality clause in a property purchase: what it really commits you to

It arrives in a few lines, before the first viewing, and it is signed unread because it looks symbolic. An undertaking of discretion is nonetheless a contract, and its drafting decides what you will be able to have checked. This page gives the reading, alongside our reference page on off-market access.

What it covers, and what it does not

A confidentiality clause in a property sale covers the circulation of information: the address, the photographs, the asking price, the seller’s identity, sometimes the very fact that the property is for sale. It protects a situation, an estate, a separation, a move, a recognisable address, and it is the logical counterpart of access before publication.

It never covers statutory duties to inform. No contractual clause sets aside the technical survey file of article L271-4 of the Construction and Housing Code, the co-ownership documents of article L721-2, the declaration of intent to sell or the notary’s checks. Those are owed to you, and owed in exactly the same way as on a property displayed in a window.

The distinction looks obvious written down, and is far less so in a conversation where you are reminded that “all of this is confidential”. The useful reflex fits in one question: does this information belong to the seller’s discretion, or to a duty the law imposes on them?

The four points to settle before signing

A good clause is recognised by the fact that it answers four questions. A clause that does not can be completed, and that is asked for without aggression, because it is customary.

• Scope: exactly which information, and from what date. A clause covering “any information relating to the property” with no further precision is unworkable and therefore dangerous.
• Authorised persons: your notary, your banker, your tax or legal adviser, the professional representing you, your spouse. That carve-out is written in one sentence and it is the most important of the four.
• Duration: an undertaking with no end is a perpetual one. Twelve to twenty-four months, or until the property is published, covers the seller’s real need.
• The sanction: the amount of the fixed penalty, where there is one. A figure disproportionate to the property’s price deserves discussion.

The signal not to miss

A confidentiality clause opposes circulation, never verification. When an intermediary invokes secrecy to refuse to produce the surveys, the general meeting minutes or the identity of the licence holder they work under, it is not a clause speaking, it is reluctance.

It is one of the six checks we set out for spotting a fake off-market, and the most revealing, because a genuinely discreet seller has no reason to object to their property being examined by the buyer’s professionals.

Confidentiality does not replace a valuation

One last side effect deserves naming. An undertaking of discretion sometimes deprives a buyer of the use they would have made of the information: showing the photos to an architect, asking a friend in the district, comparing with a neighbouring listing. So what you do not have has to be rebuilt another way.

That is exactly what our page on valuing a property with no public comparable describes: the transfers actually recorded at the address, the documented differences, and the lender’s valuation, which costs the property without being party to the transaction. None of those three sources breaches a discretion clause, and they are enough.
