Acte Authentique in a French Property Purchase: Final Signing Guide
Dernière mise à jour : 24 juil.
The acte authentique in a French property purchase is the final notarial deed that completes the sale. It is the point at which the buyer pays the balance of the price and fees, the seller transfers ownership and the notaire later publishes the deed with the French land registry.
For foreign buyers, this final signing can feel more mysterious than the offer or compromis de vente. You may be signing by power of attorney, transferring funds from abroad, waiting for mortgage release, arranging insurance and trying to understand when you actually receive the keys.
This guide explains what happens before, during and after the final deed. If you want bilingual support before signing, FrenchNotaires can match you with a bilingual notaire within 48 hours, in person or by video.
What is an acte authentique?
An acte authentique de vente is the final authenticated deed of sale signed before a French notaire. For an existing residential property, the deed must be prepared by a notaire and signed by the buyer, the seller and the notaire, or by representatives acting under valid powers of attorney.
The deed records the legal identity of the parties, the property description, the price, payment method, mortgage position, easements, co-ownership information, planning information, diagnostics and any conditions or declarations that must survive completion.
In everyday terms, this is the French equivalent of completion. Once the deed is signed and the necessary funds are available, the buyer usually becomes owner of the property. The notaire then completes post-signing formalities so the transfer is published and opposable to third parties.
When is the final deed signed?
The final deed is usually signed several weeks after the compromis de vente or unilateral promise. Many resale purchases take around two to three months between preliminary contract and completion, although the exact timing depends on the file.
Delays often come from:
mortgage approval and loan release;
the buyer's 10-day cooling-off period;
urban planning checks;
pre-emption rights, such as a municipal droit de préemption;
co-ownership documents and accounts;
missing civil status or identity documents;
powers of attorney for a buyer or seller abroad.
For the step before completion, see Compromis de Vente Explained in English. For the buyer withdrawal right, read French Property Cooling-Off Period for Foreign Buyers.
What the notaire checks before signing
The notaire's work between preliminary contract and final deed is a major part of the legal security of a French property purchase. The notaire does not carry out a building survey, but they do check the legal file.
Typical checks include:
ownership: confirming the seller has title and can sell;
mortgages and charges: checking whether existing registrations must be cleared;
planning and urbanism: reviewing municipal information and rights affecting the property;
pre-emption: ensuring any public body with a priority right has been notified where required;
diagnostics: annexing the required technical reports;
co-ownership: checking copropriété documents, charges and account adjustments where relevant;
identity and capacity: verifying the parties and their marital or company status.
If a practical issue emerges late, such as a planning problem, boundary concern or missing septic tank report, completion may need to be postponed or the deed may need specific wording.

Funds, fees and bank transfers
On or before the day of signing, the buyer must pay the balance of the price and the notarial acquisition costs. For property transactions, significant payments are made by bank transfer, not by personal cheque.
The notaire will normally send a completion statement showing:
the purchase price;
the deposit already paid, if any;
notaire fees, registration taxes and disbursements;
loan funds received from the bank, if applicable;
adjustments for co-ownership charges, property tax or other apportionments;
the final balance due from the buyer.
Foreign buyers should arrange transfers early, especially if funds are held in sterling, dollars or another currency. Always verify bank details through a trusted channel with the notaire's office. Fraudulent payment instructions are a real risk in cross-border transactions.

What happens on signing day?
The final deed may be signed on paper or electronically at the notaire's office. The notaire explains the deed, confirms the parties' consent and ensures that the financial and legal conditions are ready for completion.
In a straightforward signing, the sequence is usually:
the notaire verifies identity and representation;
the key provisions of the deed are reviewed;
the buyer and seller confirm they agree to complete;
the deed is signed by the parties or their representatives;
the notaire signs and authenticates the deed;
the seller receives the price after the notaire has completed the required steps;
the buyer receives an ownership certificate and usually the keys.
If you do not speak French fluently, ask in advance how the explanation will be handled. The notaire can often explain the key points in English if they are bilingual, but an official translation is not automatically produced for every property deed.
Keys, possession and risk transfer
In most resale purchases, the buyer receives the keys on the day the acte authentique is signed. This is also the practical moment when you take possession and become responsible for the property.
Before signing, it is wise to carry out a final visit. Check that:
the property is vacant if vacant possession was agreed;
fixtures and agreed items remain in place;
no major new damage has appeared;
meters can be read;
keys, remotes, access badges and mailbox keys are ready;
insurance will start no later than completion day.
If keys are to be handed over before or after signing, this should be documented carefully. Early key release can create insurance and liability issues. Late possession can create occupation and compensation issues for the buyer.
What happens after signing?
You do not usually leave the notaire's office with the final title deed. Instead, the notaire gives you an attestation de propriété, a certificate of ownership that you can use for practical steps such as insurance, utilities and administrative formalities.
The notaire then sends the deed for publication with the relevant land registry service, known as the service de publicité foncière. Once the publication formalities and tax stamps are completed, the authenticated copy becomes your formal title deed.
This can take several months. That delay does not mean you are not owner. The title copy is the formal registered evidence that follows the signing and publication process.
Signing remotely from abroad
Foreign buyers often do not attend the final signing in person. Instead, they sign a procuration (power of attorney) authorising a trusted person, notarial clerk or other representative to sign on their behalf.
The power of attorney must be prepared correctly, signed in the required form and returned in time. Depending on where you are, the notaire may require authentication, apostille or legalisation. Delays are common if the document is signed too late or if the signature formalities are not followed precisely.

Buyer checklist before completion
Use the final week before signing to remove avoidable friction. A delayed transfer, missing insurance certificate or unclear power of attorney can push the signing date back.
Confirm the signing date and whether you attend or sign by power of attorney.
Ask for the completion statement and payment instructions.
Verify the notaire's bank details independently.
Transfer funds early enough for cleared receipt.
Confirm mortgage funds are released, if relevant.
Arrange home insurance from completion day.
Schedule a final visit before signing.
Ask for meter readings and key inventory.
Check any conditions in the compromis have been satisfied.
Prepare identity documents and marital status documents requested by the notaire.
