Termination of lease: legal reasons and notice to be respected

Tenants and landlords are not on equal footing when it comes to terminating a residential lease. The tenant may leave at any time, without giving a reason. The landlord may only give notice when the lease expires, for one of the three grounds allowed by law, and must comply with mandatory particulars whose omission renders the notice null and void outright. This asymmetry is the key to the entire regime.

Notice given by the tenant

The tenant may terminate at any time, without having to justify it. The standard notice period is three months for an unfurnished let.

It drops to one month in several situations:

• The property is located in a designated high-demand area, which alone is sufficient, with no further condition.
• The tenant obtains a first job, is transferred, loses their job or finds a new job following a job loss.
• Their state of health, certified by a medical certificate, justifies a change of residence, and they are over sixty-five.
• They receive the active solidarity income or the disabled adults' allowance.
• A social housing unit is allocated to them.

For a furnished let, the notice period is one month regardless of the situation.

The starting point of the notice period is the date of receipt of the notice by the landlord, not the date it was sent. Notice posted on the last day of the month therefore does not start the notice period running from that day. A tenant invoking a reduced notice period must specify the ground and attach supporting evidence within the notice itself: a ground disclosed afterwards has no retroactive effect, and the notice period remains three months.

Notice given by the landlord

The landlord has no equivalent freedom. Their notice is only possible when the lease expires, with a notice period of six months for an unfurnished let and three months for a furnished one, and only for one of these three grounds:

Repossession to occupy the property. The landlord takes back the property for their own use, or for their spouse, partner, notorious cohabitant, ascendant or descendant, or those of their spouse. The notice must name the beneficiary and specify their relationship to the landlord.

Sale. The notice constitutes an offer of sale in the tenant's favour, who has a right of first refusal. It must therefore state the price and terms of the sale, and reproduce the applicable legal provisions.

Legitimate and serious grounds. This usually involves failings by the tenant — repeated late payments, disturbances to neighbours, lack of insurance. The ground must be real and sufficiently serious, and it is up to the landlord to establish it.

In addition to these requirements, an information notice must be attached to the notice for repossession or sale. Its absence is sanctioned by the nullity of the notice, on the same basis as an imprecise ground or an unnamed beneficiary.

Finally, a tenant over sixty-five with modest means benefits from protection: notice cannot be given to them unless alternative housing is offered, except where the landlord themselves meets certain age or income conditions.

The form of the notice

Three methods of notification are permitted, and only these:

• A registered letter with acknowledgement of receipt.
• A bailiff's writ.
• hand delivery against a receipt or signed acknowledgement.

An email, a message or an ordinary letter do not constitute valid notice. This formal requirement is not merely theoretical: it concerns proof of the date of receipt, on which the calculation of the notice period depends. This is the same evidentiary issue that runs through the entire tenancy file, from the lease and its appendices to the move-in/move-out inspection report.

Termination for unpaid rent

This follows a logic distinct from notice and relies almost always on the termination clause inserted in the lease.

Implementation begins with a formal demand for payment issued by a bailiff. The tenant has a statutory period to remedy the default — a period that has been shortened by a recent reform and should therefore be checked for the current year. Failing remedy, the clause takes effect and the landlord applies to the court to have the termination recorded and obtain eviction.

Two safeguards frame this mechanism. The court may grant payment deadlines, which suspend the effects of the clause as long as they are complied with. And eviction cannot be carried out during the winter truce, which runs from November to March.

The practical lesson is constant: speed of reaction matters more than the amount at stake. Unpaid rent dealt with in the first month is often resolved with a payment plan; the same unpaid rent dealt with in the sixth month is resolved through a lengthy procedure whose financial outcome is rarely satisfactory. This monitoring is part of the routines described in our property management guide.

What is settled at move-out

The end of the lease triggers two distinct processes that must not be confused.

The move-out inspection report, compared with the move-in report, determines any deductions. The return of the security deposit then follows its own timeframes, one or two months depending on whether the two inspection reports match, with automatic penalties in the event of delay, calculated per month begun.

The reconciliation of service charges for the period elapsed remains due independently of these operations, and cannot be freely offset against the deposit. The allocation between recoverable and non-recoverable charges is covered in our article on service charges.

Usage scenarios

Tenant transferred for work. The reduced one-month notice period requires that the ground be stated in the notice and justified. If invoked after sending, it shortens nothing.

Landlord wishing to sell. Notice must be given six months before expiry, state the price and terms, reproduce the provisions relating to the right of first refusal and be accompanied by the information notice. A single one of these omissions voids the notice, and the lease renews for three years.

Persistent unpaid rent. Formal demand for payment, then application to the court once the deadline expires. Factoring the winter truce into the timetable avoids discovering that the eviction obtained cannot be enforced for several months.

Frequently asked questions

Must the tenant give a reason for their notice? No, unless they claim a reduced one-month notice period. In that case, the ground must appear in the notice and be justified at the time it is sent.

When does the notice period start running? From the date the notice is received by its addressee, not the date it is sent. This is why the method of notification, which establishes that date, is strictly regulated.

Can the landlord give notice during the lease term? No. Their notice is only possible at expiry, with six months' notice for an unfurnished let. During the lease term, only termination for breach, via the termination clause, can end the contract.

What happens if a mandatory particular is missing? The notice is void. The lease continues and renews for a new period, and the landlord must wait for the next expiry date.

Can notice be given by email? No. Only a registered letter with acknowledgement of receipt, a bailiff's writ, and hand delivery against a receipt are permitted.

Can an elderly tenant be protected against notice? Yes. Beyond a certain age and subject to income conditions, notice requires an offer of alternative housing, except where the landlord themselves meets certain age or income conditions.

Key takeaways

The tenant terminates freely, subject to the notice period and required form. The landlord may only terminate at expiry, for three strictly limited grounds, and their notice is a formal act in which every particular determines its validity — naming the beneficiary for repossession, price and terms for a sale, an information notice in both cases.

For unpaid rent, the rule is different and simpler: it is the speed of reaction that determines the outcome. Formality protects those who apply it, but no procedure can make up for six months of inaction.
