Why a Formal Notice Is Always Needed
Under Article L. 145-9 of the Code de commerce, a commercial lease does not end at the contractual expiry date by operation of law. If neither party acts, the lease continues by tacit extension on the same terms. To actually terminate the lease — whether to offer renewal or to refuse it — the landlord must serve a formal congé at least six months before the intended effective date. Without this step, the clock just keeps running. Short-term derogatory leases under Article L. 145-5 are the one exception: they expire at their contractual end date, with no notice required.
Who Can Serve the Notice
The notice must be served in the name of the current owner of the leased premises at the date of service. A notice served in the name of a prior owner who has since sold is void as a matter of substance (Cass. 3e civ., 29 September 1999) — and this nullity cannot be cured retroactively. An agent or property manager can serve the notice provided they hold a specific mandate and the notice identifies the actual landlord.
Co-ownership and Usufruct
Where the property is held in co-ownership (indivision), unanimity of all co-owners is required to serve any notice — whether with or without a renewal offer. A commercial lease is treated as an act of disposition, which under Article 815-3 of the Civil Code requires unanimity, not merely a two-thirds majority (Cass. 3e civ., 23 September 2021). A notice served by less than all co-owners is void, but the defect can be covered by the intervention of the missing co-owners before proceedings are concluded. Where the property is subject to a usufruct, a renewal notice must be served by both the usufructuary and the bare owner jointly; a refusal notice may be served by the usufructuary alone, since the usufructuary will be liable for the eviction indemnity (Cass. 3e civ., 9 December 2009).
Timing: The Six-Month Rule and Effective Date
The minimum notice period is six months. Longer periods can be agreed contractually. The effective date depends on when the notice is served. A notice served for the wrong date is not void but takes effect at the correct date that should have been specified.
Takes effect on the contractual expiry date. The cleanest scenario: serve early enough to hit the natural expiry point. Tradition allowed notices given years in advance, but courts have sanctioned fraudulent premature notices designed to circumvent the tenant's rights (Cass. 3e civ., 5 March 2008).
Does not take effect at the contractual expiry. Takes effect on the last day of the civil quarter following the expiry of the six-month period from service. Result: the lease runs beyond the contractual expiry date.
Takes effect on the last day of the civil quarter following the expiry of the six-month period from the date of service. The tenant has already entered the tacit extension period; the notice terminates it at the next civil quarter end after six months.
Form: Bailiff Service Is Mandatory
Since the reversal introduced by the loi Macron of 6 August 2015, the notice must be served by a commissaire de justice (formerly bailiff/huissier). A registered letter with acknowledgment of receipt is insufficient and results in a void notice (Cass. 3e civ., 21 December 2017). Even if the lease authorises registered letter notification, that authorisation is overridden by the mandatory statutory form requirement. The notice must be served on the tenant entity (not on a management agent, not on the company's manager rather than the company itself). In the case of co-tenants, each must receive the notice individually. On the tenant's death, each heir must receive a separate notice.
Content: What Each Type of Notice Must Say
| Notice type | Required motivation | Key trap |
|---|---|---|
| Renewal offer | The offer itself is sufficient motivation; no need to state the proposed rent, though good practice to do so (omitting means new rent only owed from subsequent formal request) | Offering renewal at materially different conditions (beyond rent and duration) is treated as a refusal of renewal with eviction indemnity obligation (Cass. 3e civ., 11 Jan. 2024) |
| Refusal with eviction indemnity | Statement that tenant will receive eviction indemnity is sufficient, even without specifying amount (Cass. 3e civ., 8 Feb. 2006) | Tenant should have eviction and occupation indemnity evaluated immediately; occupation indemnity (at market value) runs from notice date until vacation |
| Refusal without indemnity — serious/legitimate reason | Specific breaches must be described precisely, with reference to prior formal notice under Art. L. 145-17-1 and failure to remedy within 1 month | Grounds fixed on service; cannot be changed after serving. Prior formal notice and waiting period are procedural prerequisites |
| Refusal without indemnity — denial of right to renew | The specific statutory ground for denial of the right to renew must be stated clearly | Wrong or insufficient ground = notice treated as refusal with eviction indemnity obligation (Cass. 3e civ., 28 June 2018) |
All notices — regardless of type — must include a verbatim statutory reminder that the tenant who wishes to challenge the notice or claim an eviction indemnity must bring court proceedings within two years of the effective date. The dominant and safe practice is to include this in all notices.
Once served, the notice grounds are fixed (principe de l'immutabilité des motifs). The landlord cannot subsequently change the stated reasons, substitute different ones, or add new ones (Cass. com., 16 March 1960). Limited exceptions: new breaches arising after service, or breaches only discovered after service. Serving a second notice is treated as a waiver of the first. Landlords who are uncertain of their grounds when they need to serve should take advice on how to frame the notice before service — not after.
Effects of the Notice and the Tenant's Options
The notice is a unilateral act that takes effect without the tenant's acceptance. Once served, the landlord cannot unilaterally withdraw it without the tenant's express agreement (Cass. 3e civ., 18 December 2002). A second notice by the landlord is treated as a waiver of the first.
Where the notice offers renewal, the tenant should not make direct rent counter-proposals. Silence does not mean acceptance of a proposed new rent — the landlord must take the initiative to apply to court within two years to fix the rent if they want an uncapped renewal. An improvident counter-proposal suggesting acceptance of a figure above the indexation-capped level has been held to constitute waiver of the capping protection. Where the notice refuses renewal with an eviction indemnity, the tenant should immediately have both the eviction indemnity and the occupation indemnity evaluated — the occupation indemnity (at market value, which may be significantly higher than the contractual rent) runs from the date of the notice until the tenant vacates.
- Who serves (Art. L. 145-9): current property owner at date of service — not a past or deceased owner (substantive nullity, incurable). Agent serving must hold a specific mandate and identify the actual landlord. Co-ownership: unanimous consent required (Art. 815-3 C. civ.); defect curable before proceedings conclude. Usufruct: joint service for renewal; usufructuary alone for refusal.
- Form — bailiff only (Cass. 3e civ., 21 Dec. 2017): commissaire de justice service is mandatory. Registered letter is void regardless of what the lease says. Serve on the tenant entity — not the manager, not an agent. Co-tenants: serve each separately. Tenant's death: serve each heir separately.
- Timing: 6-month minimum. Served ≥ 6 months before expiry → takes effect at expiry. Served later or during tacit extension → takes effect at end of civil quarter after 6-month period. Wrong effective date: not void, auto-corrected to the correct date.
- Content — grounds fixed on service: all notices must include the 2-year statutory challenge reminder. Grounds are immutable once served (Cass. com., 16 March 1960) — cannot be changed or supplemented after service. Renewal offer at materially different conditions = treated as refusal with eviction indemnity (Cass. 3e civ., 11 Jan. 2024).
- Tenant response strategy: renewal offer → silence on rent; do not make direct counter-proposals on rent level; let landlord move to court. Refusal with indemnity → evaluate eviction and occupation indemnity immediately; file court proceedings within 2 years of effective date.
The landlord's notice is the starting point for everything that follows — renewal negotiation, eviction proceedings, or indemnity claims. A defective notice can cost months and significant legal expense to unwind. We draft and review notices for landlords and advise tenants on their response strategy.
