Serving notice when lease is due to renew

Hi,

Our lease is due to renew in August 2025. I am aware that we have to serve notice that we do not want to renew this at least six months prior to this. Does anyone have the details for a Notarie that they have used to do this successfully? I would prefer to use someone that has previous experience of the French Leaseback system. For information our apartment is through SODEREV/La Grange.

Kind regards
