Buyers arriving from the United Kingdom or the United States frequently ask us the same anxious question: what stops this going wrong?

In the UK, a seller can accept a higher offer days before exchange and the buyer’s costs simply evaporate. France works differently, and the difference is deliberate: French property law assumes the buyer is the weaker party and needs statutory protection, not merely contractual goodwill. The result is one of the most buyer-friendly conveyancing regimes in Europe. Here are the safeguards you are relying on, and how to use them properly.

1. The ten-day cooling-off period

Once you sign the preliminary contract — a compromis de vente or promesse de vente — you have ten calendar days in which to withdraw for any reason, or for no reason at all.

The clock starts the day after you receive the signed contract and its full annexes by registered post or secure electronic delivery. No penalty applies. No justification is required. Any deposit already lodged must be repaid in full within 21 days of your written notice.

This right belongs to the buyer alone — once the seller signs, they are committed. Crucially, the period does not begin until the complete file has been delivered, including the diagnostic reports and, for an apartment, the copropriété documentation. An incomplete delivery can leave the withdrawal period running long after you assumed it had closed. Use the ten days properly: read the diagnostics, read the last three years of copropriété minutes, and ask the questions you were too polite to ask before signing.

2. The mortgage condition

If you are borrowing, the preliminary contract must contain a condition suspensive d’obtention de prêt. This is a statutory protection, not a negotiated favour.

The contract must specify the loan amount, the maximum interest rate and the term. If financing on those terms is refused, the sale falls away and your deposit is returned in full without deduction. The law sets a minimum period of one month for obtaining the loan; in practice notaires typically allow 45 to 60 days, and for an international application you should push for the longer end.

Two points determine whether the protection actually works for you.

First, the figures in the clause must match the loan you will genuinely need. A clause drafted for a €400,000 loan at a maximum of 3.5% offers no protection if you subsequently need €450,000 at 4%. Have your broker check the wording before the contract is signed.

Second, you must pursue the application in good faith. A buyer who never applies, or who engineers a refusal, forfeits the protection and risks losing the deposit.

You may waive the loan condition — sellers sometimes push for it in competitive situations — but the waiver must be handwritten and signed. That formality exists because the consequence is severe: without the condition, a mortgage refusal leaves you liable. Take independent advice first. Note that a mortgage can be arranged after completion in France, so waiving the condition does not mean abandoning finance — but it does mean carrying the risk yourself.

3. The Scrivener reflection period on your loan offer

The protection continues into the financing itself.

When a French lender issues a formal offre de prêt, you are legally prohibited from accepting it before the eleventh day after receipt. The delay is compulsory and cannot be shortened, even at your own request. The offer must remain open for thirty days, giving you a genuine window to compare terms.

The offer must also set out, in prescribed form, the total cost of credit — the TAEG — including interest, arrangement fees, guarantee costs and mandatory insurance. And the loan is itself conditional: if the purchase does not complete within four months, the offer lapses. The delay frustrates buyers on a tight timetable, but the reason is sound. Build it into your schedule from the start.

4. The other conditions suspensives

Beyond the loan, a well-drafted contract suspends the sale on other matters: the commune’s right of pre-emption, which gives the local authority two months to decide whether to acquire the property itself; the absence of undisclosed servitudes; a clear mortgage register; the technical diagnostics; any planning permission you require; and occasionally the sale of your existing property. Each is a door out of the contract if the answer comes back wrong. Ask your notaire which apply and make sure they are drafted in.

5. The notaire

The role has no direct equivalent in the common-law world, and it is the backbone of the system.

A notaire is a public officer, not a partisan lawyer. They verify title, conduct the searches, confirm the seller’s capacity to sell, collect the transfer taxes, draft the deed and register it. The acte authentique they produce has evidential force that a private contract does not — which is why title insurance is unnecessary in France. Notaires hold funds in regulated escrow accounts and the profession is closely supervised. A single notaire may act for both parties, which is common and entirely proper; if you would prefer your own, you may appoint a second at no extra cost, as the fee is shared rather than doubled.

6. Full disclosure, by law

The seller cannot leave you to discover problems yourself. A dossier de diagnostic technique must be annexed to the contract, covering energy performance, asbestos, lead, termites, gas and electrical installations, and natural and technological risk exposure. For an apartment, the seller must also supply the copropriété’s financial position, recent meeting minutes and the schedule of forthcoming works. The energy rating deserves particular attention in 2026: F and G rated properties face progressive restrictions on letting, and many lenders now price them less favourably or require a renovation plan.

The honest caveat

These protections are strong, but not automatic. They depend on a contract correctly drafted for your circumstances, on deadlines properly diarised, and on you actually reading what you are given. Buyers who run into difficulty in France are almost never let down by the system — they are the ones who signed something they had not read, or waived a condition they did not understand. Slow down at the preliminary contract. Everything downstream depends on it.
