What is a mortgage loan file?
The mortgage loan file brings together all contractual acts of a mortgage loan: loan offer (art. L313-24 Consumer Code), amortization schedule, European Standardised Information Form (ESIF), borrower insurance notice, possible guarantee deed. Article L313-14 requires a written loan offer delivered to the borrower, who has an irreducible 10-day reflection period before being able to accept it (Scrivener law 2 of July 13, 1979). The period runs from receipt of the offer — hence the importance of indisputable qualified timestamping.
Why sign electronically?
Scrivener period timestamped to the second
The 10-day reflection period (art. L313-34 Consumer Code) runs from receipt of the offer. Certyneo advanced signature precisely timestamps this moment with qualified timestamp — impossible to contest in case of non-enforceability dispute.
Multi-signatories (co-borrowers, guarantor)
Primary borrower + co-borrower(s) + possible guarantor. Our workflow handles sequential or parallel signature, each signatory receives an individual secure link protected by SMS OTP. Compatible with unmarried couples, civil partnerships, co-ownership.
10-year compliant archiving
Article L312-1-3 of the Monetary and Financial Code and ACPR requirements mandate preservation of loan files for 10 years after full repayment. Certyneo automatically archives the signed offer + its eIDAS audit trail for this duration.
Enforceable audit trail
Each file is delivered with a proof PDF: identity of each signatory verified by OTP, qualified timestamp, SHA-256 hash, IP. Enforceable in case of dispute over the Scrivener period, compliance of pre-contractual information or loan terms.
Procedure in 4 steps
From preparation to legal archiving, in less than 5 minutes.
1. Prepare the loan offer
Upload your loan offer compliant with art. L313-24 Consumer Code (amount, rate, duration, APR, total cost, amortization schedule). Include the ESIF, insurance notice and possible guarantee deed.
2. Send for receipt
Sending triggers qualified timestamping of receipt by the borrower. The 10-day period begins to run precisely from this timestamp.
3. 10-day reflection period
The borrower cannot sign before day 11. Certyneo technically blocks any early signature and automatically notifies expiration of the period.
4. Sign and release funds
On day 11, each borrower signs with SMS OTP. The finalized file + audit trail are archived for 10 years. Fund release can occur in accordance with the offer.
Frequently asked questions
- Can a mortgage loan offer be electronically signed?
- Yes, without restriction. Scrivener law (art. L313-14 et seq. Consumer Code) requires a prior written document but prescribes no specific form. Certyneo advanced signature + qualified timestamp allow satisfaction of formalities while accelerating processing.
- How can we be sure the 10-day reflection period is respected?
- Certyneo precisely timestamps receipt of the offer by the borrower (with qualified timestamp within the meaning of eIDAS). The period runs from that moment. The platform technically blocks any signature before day 11 and provides the audit trail proving compliance with the period — enforceable in case of non-enforceability dispute (art. L313-39 Consumer Code).
- Can an offer be signed by a couple or multiple borrowers?
- Yes. Certyneo natively handles co-borrowers (married, civil partnership, unmarried cohabiting, joint ownership). Each receives a personal secure link protected by OTP SMS on their own number. All must sign before the offer is definitively accepted.
- Must the guarantor also sign electronically?
- Yes — the guarantee deed is attached to the file and electronically signed by the guarantor(s). The handwritten mention required by art. 2297 of the Civil Code can be replaced by a typed mention + advanced signature, in accordance with recent case law on electronic acts (Cass. com. 2019).
- What signature level for a mortgage?
- Advanced signature (AES) recommended: strong DSP2 authentication via OTP SMS, single certificate, qualified timestamp. Compliant with article 26 of the eIDAS regulation and ACPR requirements for credit operations.
- How long must the file be kept?
- 10 years minimum after full loan repayment (art. L312-1-3 CMF, and loan duration + 10 years according to ACPR requirements). Certyneo automatically archives the file + audit trail for this period.
- What happens if the borrower wants to withdraw?
- Mortgage credit does not benefit from the 14-day withdrawal period (reserved for consumer credit). However, the borrower can refuse the offer within 10 days of reflection without reason. Beyond that, only the suspensive clauses of the purchase agreement allow cancellation.
- Is an electronically signed file enforceable in court?
- Yes — French case law unanimously recognizes electronic signatures compliant with eIDAS. The presumption of reliability in art. 1367 of the Civil Code makes advanced signature (AES) enforceable without further demonstration.
