French Property KYC Requirements: Complete Guide for Buyers

Every French property transaction — whether a €280,000 ski apartment in Les Arcs or a €4M chalet in Megève — goes through a structured KYC (Know Your Customer) process that is far more rigorous than what most British buyers are used to from English conveyancing. That’s not because France treats buyers with suspicion; it’s because France, like the rest of the EU, sits within a strict anti-money laundering framework in which estate agents, developers, notaires and banks each carry independent legal duties to verify identity, establish source of funds, and document the transaction chain. Understanding what is going to be asked of you before the paperwork lands on your desk is the single best way to keep a purchase moving at the pace you want.

The reality is that KYC in France is largely a paperwork exercise rather than a friction point, provided the buyer understands the sequencing and has the documents ready. Overseas buyers who are prepared arrive at each stage with the right files and move smoothly to the next step. Buyers who treat each request as a surprise end up scrambling at critical moments — particularly when the mortgage lender and the notaire both need the same documents in parallel and the 90-day window between Compromis and Acte is ticking. Our buying process guide covers the full transaction timeline; this guide focuses specifically on the KYC layer and what you’ll be asked to produce.

This matters regardless of whether you are buying with cash, with a UK mortgage, with a French non-resident mortgage, through an SCI, or as part of a VEFA (off-plan) new-build purchase. Each route adds specific KYC layers — a French mortgage, for example, triggers the lender’s independent AML checks in addition to the notaire’s — and the total documentation requested tends to accumulate across the multiple checkpoints. Below we walk through each stage of the transaction and show exactly what is being asked at that stage, by whom, and how to prepare so the process feels routine rather than intrusive.

French property KYC derives from the EU’s Anti-Money Laundering Directives (AMLD), transposed into French law and tightened incrementally over the last two decades. The sixth directive (6AMLD), in force since 2021, harmonised predicate offences across member states and increased the minimum sanctions for non-compliance. France went further in 2023–2024, imposing stricter verification standards on non-resident transactions and on properties above €500,000 — the threshold above which enhanced due diligence (EDD) is now mandatory regardless of nationality. Ski-property transactions almost always sit above this threshold.

The system is designed to catch three specific things: the use of property purchases to launder illicit funds, the use of complex ownership structures (SCIs, trusts, nominees) to obscure beneficial ownership, and the movement of capital through jurisdictions where source-of-funds checks are weak. None of this applies to the overwhelming majority of genuine buyers, but the checks are mandatory for every transaction because the system works only if it’s applied universally. Think of it less as a challenge to your legitimacy and more as a regulatory cost that every buyer and every intermediary pays to participate in the market.

The parties with KYC obligations in a French transaction are, in order: the estate agent or developer who first takes your offer, the buyer’s lawyer if one is instructed (optional in France), the notaire who handles the actual conveyance, the French mortgage bank if financing is involved, and in some cases the French tax authorities if the property is being held through a corporate structure. Each party has independent obligations under French and EU law — meaning you may be asked for the same documents multiple times at different stages. This feels redundant but is actually protective: each checkpoint is a separate regulatory firewall.

The legal framework also imposes a suspicion reporting obligation on every professional in the chain. If a notaire believes that the source of funds is not clearly documented, or that the ownership structure obscures the beneficial owner, they have a legal duty to file a report with TRACFIN (France’s financial intelligence unit) — and they can be held personally liable for non-compliance. In practice this means notaires take the KYC step seriously. The buyer’s interest is to make their file crystal-clear so the notaire has nothing to flag.

The first KYC request comes at the point of offer acceptance — or, for a VEFA (off-plan) reservation, at the point the reservation contract is drawn up. At this stage the estate agent or developer typically asks for a partial KYC pack: a scanned copy of your passport (or national ID card for EU buyers), proof of residential address no older than three months (recent utility bill, bank statement or council tax bill), and a self-declaration of profession and approximate income bracket. For a resale transaction this pack is usually enough to move to the Compromis stage; for a new-build reservation it’s typically enough to unlock the developer’s reservation contract.

For overseas or high-value buyers, the agent or developer may escalate to enhanced due diligence at this first stage rather than waiting for the notaire. EDD adds a few items: a second form of photo ID (driving licence), a more recent bank statement showing regular income, and — critically — an early indication of where the deposit funds will come from. Agents who handle significant numbers of non-resident transactions (including Domosno) are experienced at requesting this upfront in a way that feels like routine paperwork rather than interrogation. The purpose is to avoid a last-minute scramble at the notaire stage when the lender or notaire raises a query the agent could have resolved weeks earlier.

Practical tip: once you’ve decided to make an offer, email a single PDF containing your passport scan, a recent utility bill and a brief cover note explaining your employment, source of funds and approximate timeline to completion. That gives the agent everything they need for the initial KYC and it positions you as a serious, well-prepared buyer — which in a competitive market is worth more than most people realise. Sellers and developers both prefer to deal with buyers who won’t get stuck at a later stage; an early, organised KYC pack is a quiet but effective signal.

The Compromis de Vente — the French equivalent of exchanging contracts in English conveyancing — is where KYC steps up significantly. For a resale transaction, the Compromis is typically prepared by the buyer’s notaire (in France the notaire is a neutral state-regulated official rather than an advocate for either side) and signed by both parties roughly two to six weeks after offer acceptance. A 10% deposit is paid into the notaire’s escrow account at this point, and the clock starts on the 10-day statutory cooling-off period during which the buyer can unconditionally withdraw.

At the Compromis stage the notaire runs full KYC on the buyer: certified copies of passport, birth certificate (with sworn translation if not issued in French), marriage or PACS certificate if applicable, proof of address, and a comprehensive declaration of source of funds. The source-of-funds declaration is the most important element for UK buyers — expect to provide evidence of the origin of the deposit (bank statements showing the accumulation of the funds over at least six to twelve months), a narrative explanation if any part of the funds came from a one-off event like a property sale, inheritance or business disposal, and supporting documentation for that one-off event (solicitor’s statement for a UK property sale, probate documents for inheritance, share sale agreement for a business exit).

For VEFA new-build purchases, the equivalent stage is the signing of the reservation contract, followed several months later by the Acte de Vente at completion. The reservation contract triggers a smaller deposit (typically 2% or 5% into an escrow account) and activates a different cooling-off period. KYC at the reservation stage tends to be lighter than at a resale Compromis — the full deep dive happens in the months before the Acte signing, giving the buyer and developer more time to assemble documents. This is one of the many reasons VEFA purchases tend to feel less time-pressured than resale transactions, and why our new-build ski apartments route is particularly popular with first-time French buyers.

If you take away one single point from this guide, make it this: the source-of-funds documentation is the single most important element of French property KYC, and the buyers who sail through the process are the ones who have a clean, documented paper trail for every euro in the transaction. The French system is looking for continuity — evidence that the funds were accumulated through legitimate activity over time, rather than appearing suddenly from an unexplained source. For most British buyers this is a non-issue because their funds come from obvious places (salary, pension lump sum, UK property sale), but it needs to be documented rather than assumed.

Typical source-of-funds documentation falls into three categories: ongoing income (recent P60s or tax returns, three to six months of recent bank statements showing salary or pension deposits), accumulated savings (bank and investment account statements going back 12–24 months showing gradual accumulation), and one-off events (UK property sale completion statements, inheritance probate documents, business sale agreements, pension tax-free lump sum confirmation letters). If the deposit comes from multiple sources, you’ll be asked to document each of them separately with a narrative explaining how the amounts combine into the transaction deposit.

Where KYC genuinely slows a transaction is when the source of funds involves cryptocurrency, cash transactions, funds from high-risk jurisdictions, or complex multi-jurisdictional structures. Cryptocurrency proceeds can be used in a French property purchase but require a documented audit trail back to the originating exchange, a full KYC-complete identity verification at that exchange, and often an accompanying tax-declared capital gains position. Cash funds are essentially impossible to use directly — they need to be deposited in a bank account first, held for a reasonable period, and then transferred to the notaire’s escrow account. The notaire is obligated to refuse funds they cannot trace, and buyers who underestimate this routinely see their transaction stall at the last moment.

If the purchase involves a French non-resident mortgage — which it does for many British buyers, because French mortgage rates in 2025 remain meaningfully cheaper than equivalent UK remortgage rates — the lender runs its own parallel KYC process. This is separate from the notaire’s checks and serves a different purpose: the bank is assessing creditworthiness, serviceability and risk, and it has its own AML obligations. Expect a detailed application pack including three to six months of bank statements, two to three years of tax returns or P60s, an employer’s letter or accountant’s certification (for self-employed applicants), proof of existing debts, and evidence of the deposit sitting in an accessible account.

The bank KYC typically starts around the time of the Compromis signing and runs in parallel with the notaire’s checks, aiming to have a binding mortgage offer (offre de prêt) in hand by the time the 45-day mortgage condition window in the Compromis expires. The two processes are independent — you provide the same documents to both parties — but the notaire relies on the bank’s sign-off before the Acte de Vente can proceed, because funds are released through the notaire’s escrow at completion. In practice the mortgage broker coordinates the two timelines for the buyer, and a good broker materially de-stresses the entire KYC experience by knowing exactly which documents each lender wants and in what format.

A specific point for non-UK buyers: French lenders prefer applicants who can provide full historical documentation in a format they recognise. British applicants typically have no trouble here because UK banks issue standardised statements that translate easily. Applicants from jurisdictions with less standardised banking documentation sometimes struggle and end up needing apostilled translations, which adds time and cost. If you’re buying from outside the UK, budget an extra 2–4 weeks for document preparation and ask your broker upfront what the specific lender will accept.

The final KYC checkpoint is at the Acte de Vente — the notarial signing that transfers title. By this stage, most of the documentation should already be in the file and the Acte itself is largely a formal confirmation. The notaire typically runs a last-minute identity check on the buyer (and, for non-residents, a final confirmation that the identity documents are still current), verifies the source of the final balance of funds now that the full amount has landed in escrow, and confirms there have been no material changes to the buyer’s circumstances since the Compromis.

The final balance of funds — the gap between the 10% deposit already held in escrow and the full purchase price plus notary fees plus any taxes — needs to arrive in the notaire’s account at least a few days before the Acte is signed. For international buyers this typically means initiating a SWIFT transfer a week before the signing date, with clear reference to the transaction and a matching narrative confirming the source of the amount (consistent with the source-of-funds declaration signed at the Compromis stage). Any discrepancy — an amount arriving from an account or source that wasn’t disclosed at Compromis — will be flagged and may delay completion. This is a simple point but an easy one to get wrong.

Once the Acte is signed, title is transferred, the notaire processes the registration with the French land registry (Service de la Publicité Foncière), and the transaction is complete from a legal and KYC standpoint. Residual administrative items — CPAM registration, opening utility accounts, registering for taxe foncière and taxe d’habitation — are post-completion steps covered in our buying process guide. For VEFA purchases, there are additional checkpoints at each construction milestone, but the KYC dimension is effectively closed at the Acte.

If you’re about to enter a French property transaction, prepare your KYC pack before you start viewing properties. The documents you’ll need are entirely routine and don’t go out of date quickly, so assembling them in advance costs nothing and saves days at each transaction stage. The core pack is: a clear colour scan of your passport (valid for at least 12 more months), a utility bill or bank statement dated within the last three months, a recent payslip or pension statement, your last P60 or tax return, and an up-to-date bank statement showing the intended deposit funds. For a couple buying jointly, each spouse needs their own identity and address documentation.

For source of funds, gather 12 months of statements for each account that will contribute to the deposit, plus any supporting documents for one-off additions (solicitor’s statement for a UK property sale, probate for inheritance, pension lump sum confirmation for a drawdown). Write yourself a one-page narrative explaining how the funds were accumulated — not a formal document, just notes you can convert into a formal declaration when the notaire asks. Keep all of this in a dedicated folder so you can respond to any document request within hours rather than days. The Domosno team has seen hundreds of British buyer files and can give topic-specific guidance on what a strong source-of-funds narrative looks like for different buyer profiles.

One final tip: if any part of your financial situation is unusual — recent divorce, a partial inheritance, a business sale with earn-outs, cryptocurrency proceeds, or a family gift — flag it to your agent and notaire early rather than hoping it won’t come up. Early disclosure almost always results in a clean KYC; late disclosure almost always results in a transaction stall and a difficult conversation. French notaires have seen every variation of complex family finances and are almost always willing to work with a buyer whose circumstances are documented and honestly declared. They are rarely willing to work with a buyer whose paperwork has surprises in it.
