How to cancel Lybernet Assurances by mail
Get your account details together
Put the policy number, the name on the policy and the date you want cover to end in front of you before you write: the request to Lybernet Assurances is only as good as the details it quotes.
Write your request
Lybernet Assurances is based in France, so the letter goes out in French, built from our French template. Subject line: “Objet : Demande d'annulation – [your name]”. It asks for the subscription to end, for further charges to stop and for written confirmation.
Send it by certified mail
Mail the letter by certified mail to the Cesson-Sévigné address in the next section, and keep the tracking number.
Keep proof the letter arrived
Delivery confirmation is your evidence that Lybernet Assurances was asked. Watch the next statement or two for any further Lybernet Assurances charge.

Cancelling a insurance or protection plan
Insurers cancel by policy and by effective date, so the request has to name the policy number and the date cover should stop, ideally after replacement cover is in place.
A mailed letter is slower than a phone call but it is the version that proves what you asked for and when.
