Electronic Signature for Local Government Authorities in...

Why Electronic Signature Has Become Essential for Local Government Authorities

The digitalization of administrative procedures is today a priority for town halls, departments, regions and local public institutions. Since the entry into force of Ordinance No. 2014-1329 of November 6, 2014 on remote deliberations of deliberative bodies of local government authorities, and even more with the Public Action 2022 program led by the government, electronic signature for local government authorities has become a strategic lever for modernization. By 2026, nearly 87% of French regions have deployed at least one digital signature system according to SGMAP data, and the movement is now expanding to municipalities with fewer than 3,500 inhabitants.

The generalization of contract digitalization within local government — public procurement, partnership agreements, deliberations, orders — responds to a triple logic: operational efficiency, legal certainty and public demand for transparency. This article guides you through the regulatory foundations, applicable signature levels, concrete use cases and best practices to adopt for a successful digital transition.

A Regulatory Context in Full Consolidation

The European directive on public procurement (2014/24/EU), transposed into French law by Decree No. 2016-360, requires complete digitalization of public procurement procedures above €40,000 excl. VAT since October 1, 2018. In parallel, the eIDAS Regulation No. 910/2014 established a harmonized framework for mutual recognition of electronic signatures across all Member States, a foundation that the eIDAS 2.0 revision (EU Regulation 2024/1183, which came into force in May 2024) further strengthens with the introduction of the European digital identity wallet (EUDIW).

For local government authorities, this concretely means that any act engaging the legal entity — municipal order, public contract, public service delegation agreement — can and should be able to be signed electronically, provided the right signature level is chosen according to the nature and risk of the act.

The Three Levels of Electronic Signature Applicable to Local Government

The eIDAS regulation distinguishes three levels of signature, whose relevance varies depending on the administrative act in question.

Simple Electronic Signature (SES)

Simple electronic signature constitutes the minimum level. It is based on electronic data attached to other data (a click of acceptance, a verified email address) without requiring third-party certification. It is suitable for acts with low legal risk: receipts of receipt, internal convocations, standard administrative forms. For a municipality, it can be used for managing online registrations or confirmation of administrative appointments.

Caution: simple signature offers only limited presumption of reliability and its enforceability in litigation can be contested. It is therefore unsuitable for contracts committing significant expenditures or acts subject to legality review.

Advanced Electronic Signature (AES)

Advanced signature is uniquely linked to the signatory, allows their identification, is created from data that the signatory can keep under their exclusive control, and is linked to the signed data in a way that detects any subsequent modification. It is generally based on a digital certificate issued by a qualified trust service provider (QTSP) listed on the French trust list (Trust Service Status List – TSL).

For public procurement below threshold and inter-local government partnership agreements, advanced signature represents a good balance between security and operational fluidity. Many modern SaaS solutions, including Certyneo, allow this level to be deployed with strong authentication (OTP SMS + document verification), without requiring a hardware key.

Qualified Electronic Signature (QES)

Qualified signature is the highest level provided for by eIDAS. It is mandatory based on a qualified certificate issued by an accredited QTSP, and is generally created using a qualified signature creation device (QSCD) — smart card, USB token or, since eIDAS 2.0, qualified remote signature creation service. It benefits from a legal presumption of equivalence to handwritten signature in all Member States (Article 25§2 of eIDAS Regulation).

This signature is recommended — or even mandatory — for the most sensitive acts: delegations of signature from the mayor or president of departmental council, large-scale public contracts, acts subject to prefectoral legality review. The cost and complexity of implementation are higher, but the absolute legal certainty it provides makes it the unavoidable standard for local authorities managing a large volume of high-stakes contracts.

Digitalization of Contracts: Which Acts Are Concerned in Practice?

Contract digitalization in municipalities and town halls covers a very broad spectrum of administrative acts. Understanding which are priority allows organizing a progressive and controlled rollout.

Public Procurement and Framework Agreements

Since the order of March 22, 2019 establishing the methods for making available consultation documents and communication between buyers and economic operators, electronic signature is mandatory for formalized contracts (thresholds > €215,000 excl. VAT for supplies and services). The AAPC (Notice of Public Call for Competition), the CCAP, the CCTP and commitment documents must be signed by the legal representative of the local authority and by the contract holder.

The buyer profile (public procurement digitalization platform) must be interoperable with signature tools. An API integration with a solution like Certyneo allows automating document sending, signature collection and archiving at probative value in an electronic vault compliant with NF Z 42-013.

Agreements and Deliberations

Public service delegation agreements (DSP), agreements on use of public domain, partnership agreements with associations or other legal entities, as well as deliberations of municipal council or deliberative assembly can all be digitalized. For the latter, Decree No. 2020-1407 of November 18, 2020 relaxed the conditions for resorting to remote meetings, opening the way to electronic signature of minutes.

Civil Status Acts and Administrative Orders

Danger orders, administrative police orders, urban planning acts (building permits, prior declarations) can also be signed electronically. The Legal and Administrative Information Directorate (DILA) has developed the @ctes portal for digitalized transmission of acts subject to legality review to the prefecture, with integration of the mayor's or president's electronic signature.

If your local authority also deploys electronic signature in its HR processes — recruitment, contract amendments, training — the dedicated guide on electronic signature for HR will provide you with a precise reference framework.

Choosing and Deploying a Digital Signature Solution Suited to Public Sector Constraints

Local government authorities face specific constraints that generalist market solutions do not always integrate: data hosting on national or European territory, compatibility with existing information systems (Berger-Levrault, Sedit Marianne, Civil Net...), management of authorizations by delegation, and traceability requirements for legal archiving.

Selection Criteria for a Compliant Solution

Several criteria should guide the choice:

• Provider qualification: the provider must be listed on the national trust list (French TSL published by ANSSI) or on the consolidated European list (EU Trusted Lists). eIDAS qualification is a non-negotiable minimum guarantee.
• Sovereign hosting: data processed by local authorities often fall under administrative confidentiality or personal data within the meaning of GDPR. Hosting certified as HDS (Health Data Host) or qualified SecNumCloud is strongly recommended for the most sensitive processing.
• Interoperability: the solution must integrate via REST API with customer relationship management systems (GRU), business software and public procurement platforms (AWS, Klekoon, e-Public Markets...).
• Archiving at probative value: the signed document, accompanied by its metadata (qualified timestamping, certificate chain, verification report), must be archived in a system compliant with NF Z 42-013 or ISO 14721 (OAIS).
• Management of delegations and authorizations: a municipality must be able to configure signature workflows reflecting its internal delegations (delegation from mayor to DGA, joint signature of two elected officials, etc.).

Progressive Implementation: The Recommended Method

The DGFIP and the AMF (Association of Mayors of France) recommend a three-phase approach: (1) audit of existing situation and mapping of acts to be digitalized, (2) pilot on a limited scope (e.g., regular supply contracts), (3) generalization with staff training and communication with external partners.

The Certyneo ROI calculator can help you quantify the expected return on investment according to the volume of contracts processed annually by your local authority, taking into account the costs of printing, postage, physical storage and administrative management.

Finally, for local authorities already equipped with an existing solution and wishing to migrate to a more efficient platform, the migration offer to Certyneo provides turnkey support including data recovery and continuity of ongoing workflows.

Legal Framework Applicable to Electronic Signature in Local Government Authorities

Electronic signature used by local government authorities is part of a coherent regulatory structure that must be mastered to secure each digitalized act.

Civil Code, Articles 1366 and 1367: Article 1366 provides that "electronic writing has the same probative force as writing on paper, provided that the person from whom it originates can be duly identified and it is established and preserved in conditions such as to guarantee its integrity." Article 1367, for its part, recognizes the validity of electronic signature when it "consists in the use of a reliable identification process guaranteeing its link to the act to which it is attached," with a reinforced presumption of reliability when qualified eIDAS signature is used.

eIDAS Regulation No. 910/2014 of the European Parliament and Council: This regulation, directly applicable in all Member States, defines the three levels of electronic signature (simple, advanced, qualified), establishes requirements applicable to qualified trust service providers and guarantees cross-border recognition of qualified signatures (Article 25). The eIDAS 2.0 revision (EU Regulation 2024/1183) strengthens these provisions and introduces the European digital identity wallet (EUDIW).

GDPR Regulation No. 2016/679: Processing of personal data of signatories (identity, contact details, biometric data if any) is subject to the principles of minimization, purpose and security of GDPR. Local authorities must maintain a register of processing and ensure that their provider acts as a processor with a DPA (Data Processing Agreement) compliant with Article 28.

NIS2 Directive (EU 2022/2555): Transposed into French law by Law No. 2023-703 of August 1, 2023 and its implementing decrees, the NIS2 Directive imposes on public administrations — including local authorities of significant size — strengthened requirements in terms of cybersecurity, in particular the management of risks related to the digital supply chain. The signature provider must be able to document its security measures.

ETSI EN 319 132 and EN 319 122 Standards: These standards define the formats of advanced electronic signature (XAdES, CAdES, PAdES) accepted in public procurement. The PAdES-B-LTA format (PDF Advanced Electronic Signature with Long Term Archival) is particularly recommended for contractual documents that must be preserved for long periods.

Ordinance No. 2014-1329 and Decree No. 2020-1407: These texts regulate remote deliberations and electronic signature of acts of deliberative bodies of local government authorities.

Legal Risks in Case of Non-Compliance: An act signed with an inappropriate signature level or by a non-qualified provider can be annulled by the administrative judge in case of litigation. Prefectural legality review can also reject acts transmitted through non-compliant channels. It is therefore imperative that the Data Protection Officer (DPO) and the legal department of the local authority validate the deployment framework before any production implementation.

Concrete Use Case Scenarios in Local Government Authorities

Scenario 1 — A Medium-Sized Municipality Digitalizes Its Road Work Public Contracts

A municipality of approximately 25,000 inhabitants manages between 40 and 60 public contracts annually, including about twenty above the formalized competitive tendering threshold. Before digitalization, each contract required printing 3 to 5 copies of the contractual file, a physical signature process involving the mayor, the DGA and the public accountant (DGFIP representative), then sending by registered mail to the holder and to the prefecture for legality review. The average time between award and contract notification reached 18 business days.

After deploying a qualified electronic signature solution integrated with its buyer profile, the municipality reduced this timeline to 4 business days, a reduction of 78%. Direct savings on printing, postage and archival management costs were estimated at approximately €12,000 per year. Legality review, now conducted via the @ctes portal with electronic signature, takes 48 hours compared to an average of 7 days previously.

Scenario 2 — A Department Digitalizes Its Subsidy Agreements to Associations

A departmental council awards over 1,200 subsidies to local associations annually, each giving rise to a bilateral agreement. Paper management mobilized a team of 4 agents part-time for 3 months per year, with a rate of return of signed agreements within deadlines barely above 60% — associations often delaying in returning signed documents.

After deploying an advanced electronic signature solution in white-label, the department automated sending of agreements by electronic means with automatic reminders. The signature completion rate within deadlines rose to 94% in the first year. The gain in full-time equivalents represents approximately 1.2 FTE/year. Automatic archiving in a digital vault compliant with standards also reduced physical storage costs by 35%.

Scenario 3 — An Intercommunal Body Secures Its Community Council Deliberations

An agglomeration community grouping 18 municipalities holds on average 12 community councils per year, each producing between 20 and 50 deliberations. Physical signature of each deliberation by the president and delegated vice-presidents involved heavy logistics, with travel sometimes difficult for elected officials living in peripheral municipalities.

By deploying a remote qualified signature workflow, allowing each elected official to affix their signature from their smartphone or computer with their personal certificate, the intercommunal body eliminated geographical constraints and reduced deliberation finalization time from 12 days to an average of 2 days. The savings from travel (mileage, staff time) was estimated at approximately €8,500 per year. Complete traceability of signatures and timestamps also simplified responses to contentious appeals.

Conclusion

Electronic signature has established itself as a structuring tool for modernizing local government authorities. Whether public procurement, partnership agreements, deliberations or administrative orders, contract digitalization in town halls and municipalities offers measurable gains: reduced processing times, direct savings on administrative costs, strengthened legal certainty of acts and improved relationship with partners and service providers. The regulatory framework — eIDAS, Civil Code, GDPR, NIS2 — provides a solid foundation for securing this transition, provided a qualified provider is chosen and the signature level is calibrated to the risk of each act.
