What the status means
- Required by law
- The law prescribes registered mail, sometimes as one of a short list of accepted methods. Another channel can make the letter invalid.
- Recommended
- No form is prescribed, but a deadline or the need to prove receipt makes registered mail the usual safe choice.
- Often required by contract
- The law sets no form. Contract terms often ask for registered mail, so check yours.
- Not needed
- Email, an online form or a cancellation button is valid and common. Registered mail adds little.

Tenant's notice to end a residential lease
Local rules: The shorter 1-month notice depends on the municipality: it applies in the high-demand areas (zones tendues) listed by decree.
The law sets a closed list of ways to give notice, and the registered letter with acknowledgement of receipt (LRAR) is one of them. The notice period runs from the day the landlord receives it, so the receipt matters.
- Deadline
- 3 months' notice for an unfurnished home; 1 month for a furnished home, in a high-demand area (zone tendue) or in certain cases (job transfer, job loss, health), provided the letter states and proves the reason.
- Other valid ways
- Registered letter with acknowledgement of receipt (LRAR), service by a commissaire de justice, or hand delivery against a signed receipt; an electronic registered letter is valid if a private landlord agreed to it beforehand, a plain e-mail is not.

Landlord's notice to end a residential lease
A landlord can only give notice for the end of the lease term, on a reason allowed by law (sale, moving in, serious reason), and by one of the methods set by law. If the tenant does not collect the registered letter, the notice period does not start, so send it early or use a commissaire de justice.
- Deadline
- The tenant must receive the notice at least 6 months before the lease ends for an unfurnished home, 3 months for a furnished one.
- Other valid ways
- LRAR (registered letter with acknowledgement of receipt), service by a commissaire de justice, or hand delivery against a signed receipt; an electronic registered letter only if the tenant agreed beforehand.

Reply to a rent increase
Local rules: Rent control only applies in some cities (for example Paris, Lille, Lyon), where the rules on increases are stricter.
The law sets no form for a tenant who disputes a rent review or increase. If you disagree, a registered letter with acknowledgement of receipt proves the date of your objection before you go to the departmental conciliation committee.
- Deadline
- For an increase proposed at lease renewal, the conciliation committee can be asked to step in if there is no agreement 4 months before the lease ends.
- Other valid ways
- No set form: a plain letter, an e-mail or a direct conversation is enough, but a registered letter with acknowledgement of receipt is advised if you disagree.

Request to return the rental deposit
The law sets no form for the tenant's request, but official guidance advises a formal notice by registered letter with acknowledgement of receipt. It proves the request and opens the way to the conciliation committee or the court, with a late-payment penalty owed by the landlord.
- Deadline
- The landlord must return the deposit within 1 month after the keys are handed back if the move-out inspection matches the move-in one, otherwise within 2 months.
- Other valid ways
- A plain letter or e-mail can do at first; the formal notice is in practice sent by LRAR (registered letter with acknowledgement of receipt).

Request for repairs to the landlord
The law sets no form, but if the landlord does nothing, a formal notice by registered letter with acknowledgement of receipt is the expected step before the conciliation committee or the court. Do not stop paying rent in the meantime.
- Deadline
- If there is no reply or agreement 2 months after the formal notice, the tenant can go to the conciliation committee or the court.
- Other valid ways
- You can report it by plain letter, e-mail or in person; the formal notice should go by LRAR (registered letter with acknowledgement of receipt) or handed over in person.

Commercial tenant's notice to end a lease
For a commercial lease, the law only accepts two ways for the tenant to give notice: a registered letter with acknowledgement of receipt or service by a commissaire de justice. Notice sent too late is pushed back to the next three-year period.
- Deadline
- At least 6 months before the end of the current three-year period.
- Other valid ways
- LRAR (registered letter with acknowledgement of receipt) or service by a commissaire de justice; a notice from the landlord must go through a commissaire de justice.

Work
Resignation letter
The Labour Code sets no form for resigning, but the intention must be clear and unambiguous. A dated letter with proof of receipt avoids disputes about when the notice period starts; the collective agreement or the contract may require it in writing.
- Deadline
- The notice period depends on the collective agreement, the contract or custom; it starts when the letter is handed over or first presented.
- Other valid ways
- Resignation can be given orally or in writing; hand delivery against a signed receipt or LRAR (registered letter with acknowledgement of receipt) are the advised ways.

Dismissal letter from the employer
The law says the employer must notify the dismissal by registered letter with acknowledgement of receipt (LRAR), stating the reason. The notice period starts when the letter is first presented.
- Deadline
- The letter cannot be sent earlier than 2 working days after the prior interview; for a disciplinary dismissal, no later than 1 month after it.
- Other valid ways
- Courts also accept hand delivery against a signed receipt; the invitation to the prior interview is sent by LRAR (registered letter with acknowledgement of receipt) or handed over against a signed receipt.

Insurance and subscriptions
Cancelling an insurance policy
Since 2023, a registered letter is no longer required: the law accepts a plain letter or e-mail, and an online cancellation button when the policy can be taken out online. The same applies to individual top-up health cover (mutuelle).
- Deadline
- After the first year, you can cancel at any time, effective 1 month after receipt; before that, at the annual renewal date shown on the renewal notice.
- Other valid ways
- Online, by letter or any durable medium, by declaration at the insurer's office, by a commissaire de justice, or by the same means used to sign up; after one year, the new insurer can do it for you.

Cancelling a subscription (gym, press, services)

- Deadline
- The provider must inform you between 3 months and 1 month before the deadline to stop automatic renewal; respect the deadline set in the contract.
- Other valid ways
- Three-click online cancellation if the contract can be signed up for online; otherwise the method set in the contract (often LRAR, sometimes e-mail).

Money and debts
Formal notice to pay (mise en demeure)
The law requires a formal demand or a written notice that clearly calls on the debtor to pay, without prescribing a registered letter. In practice, the registered letter with acknowledgement of receipt is the usual route, because it proves the date and starts late interest; it later serves as evidence for a payment order.
- Other valid ways
- A demand served by a commissaire de justice, or any sufficiently clear written demand; the contract can also say that the due date alone counts as formal notice.

Disputing a claimed debt
There is no set form to dispute a sum claimed by a creditor or a debt collection agency. A registered letter with acknowledgement of receipt proves the date and content of your dispute if the case goes to court.
- Deadline
- If a payment order is served on you, you must lodge an objection within one month.
- Other valid ways
- A plain letter or e-mail is possible; LRAR (registered letter with acknowledgement of receipt) is advised to keep proof of the dispute.

Appeal to the Caf, CPAM or Urssaf review board (recours amiable)
The appeal to the review board (commission de recours amiable) is a required step before court, and it must be made within 2 months. The law does not require registered mail, but Service-Public advises a registered letter with acknowledgement of receipt to prove the board was seized in time.

Consumer purchases
Withdrawal from a distance purchase (14 days)
The law accepts any clear statement and forbids the seller from requiring a registered letter. Simply sending the product back without a statement is not enough; keep proof of your statement.

- 14 days from receiving the goods or concluding the service contract; extended by 12 months if the seller did not inform you of this right.

No form is set, but official guidance advises notifying the seller by registered letter with acknowledgement of receipt, with proof of purchase. It fixes the date of the claim, which matters for the repair deadline and any dispute.
- Deadline
- 2 years from delivery; the seller must repair or replace within 30 days.
- Other valid ways

FAQ
Which letters must go by LRAR in France?
A tenant's or landlord's notice on a home, a commercial tenant's notice, a dismissal letter and a traffic fine appeal sent by post. For notice on a home the law also accepts service by a commissaire de justice or hand delivery against a receipt; a fine can also be appealed online.
Can an email replace an LRAR where the law asks for one?
No. Where the law names the registered letter with acknowledgement of receipt, an email does not replace it. For notice on a home, an electronic registered letter only counts if the other side agreed to it beforehand. The acknowledgement dates the delivery, and the notice period often runs from that date.
Do I need registered mail to cancel insurance or a subscription in France?
For insurance, no: a plain letter, an email or, since 1 June 2023, the online cancellation button is enough. For a subscription the law sets no form, but the terms often ask for a registered letter; if you signed up online, the business must offer online cancellation.
What happens if the recipient does not collect the letter?
It depends on the letter. For a landlord's notice, the notice period does not start if the tenant does not collect it, so send it early or use a commissaire de justice. For a dismissal, the notice period runs from the first presentation.
Does a resignation have to go by registered mail?
No. The Labour Code sets no form, but the intention must be clear. A dated letter with proof of receipt avoids disputes about when the notice period starts; the collective agreement or the contract may require it in writing.
