Paul, this is the list of requirements sent out by the prefecture in Poitiers. Since December 1st British residents in the department send copies of the relevant documents by post and await an email telling them that their card is ready to collect and giving an appointment to do so. There is no language requirement.

And I feel bound to add that the procedure operated by the Préfecture in St Lo (Manche) has been and remains quite different from the systems operating elsewhere, as applications are received but no receipt was given, and no notifications of any kind have yet been issued (in our case since April) presumably because of the uncertainty surrounding Brexit.
I am not aware that any applications from UK/EU citizens have been fulfilled by St Lo by the issue of a Titre de Sejour.
If there is no âdealâ, then our applications for Titre de Sejour (which were told EU citizens did not need) will be invalidated by our leaving the EU and relinquishing our EU entitlements. The application form was clearly marked for the use of EU citizens.
That makes sense to me so I fail to see how it doesnât seem prudent for the French to wait until dawn on 30 March when weâve brexited. Then it may seem obviously right for them to shred all the pending dossiers, and start the process over again in the light of altered circumstances.
If there is a âdealâ, or if Article 50 is revoked and we remain in the EU, the whole sorry business can be put wearily to rest. Some hopes!
You might need this one
Thatâs my understanding, David @Aquitaine, (re your recommended reading) and we have no illusions about the future scenario in the event of their being no withdrawal agreement.
As we are a retired couple much will depend on the portability of our pensions, and the rate of exchange. If the pound lost value so as to reduce our net income by more than 40% we would be challnged, but presumably we would pay less income tax and have some entitlement to abatements on TdH. We are used to adversity and major material reverses e.g. homelessness and starting over from destitution.
Health insurance might present difficulties, perhaps, but we could budget for basic health cover, and - so far - we are both in good health. I would not struggle to stay alive if struck down with an illness that robbed me of my capacity for self-care. I reckon my wife would take the same position. We are both retired nurses and know the ropes, and when to call it a day!
So keeping fingers crossed and thinking, after Voltaire, âJâai dĂ©cidĂ© dâĂȘtre heureux, parce que câest bon pour la santĂ©â 
Hereâs the latest (14 Dec 2018) advice from the UK government as far as CdS applications in France go - scroll to the section âRegistration in Franceâ
Health care will not be a problem. If your S1 is withdrawn you will be able to apply through PUMA. Hopefully you will be issued with a 5 year card, lots of people in my area who have only lived in France a couple of years have, and when that needs renewing income will not be an issue. Think positive. 
Iâm still hoping article 50 is revokedâŠthe billions now being ploughed into a no deal brexit are turning my occasional flickers of anxiety into gigantic manic butterfliesâŠx 
Well, I suppose it is, Mat, and I have given it thought. But managing a situation in theory is one thing, practice is another.
My philosophy is that I shall face what comes, whatever comes, and trust what comes as it unfolds. My consciousness never presents what it knows I cannot face, and that has never let me down so far.
My relatively short sejour in France has opened my eyes to the cycle of life, mainly through my living, breathing garden and its inhabitants, and the importance of death in closing the circle 
Spooky or what?
A very reassuring touch, David , will keep my suuny side upâŠ
I donât think weâre disagreeing on the ânormalâ CdS, EU citizen or not.
The service-public site wasnât found by me, it came up in another thread, donât recall which for a second but it definitely talks about the carte de rĂ©sident permanent as a thing distinct from a carte de rĂ©sident de longue durĂ©e - UE - Iâm not imagining this, my French is good enough to translate what is on the page.
No-one has really said what the carte permanent mentioned is actually about - SImon maintains it is the same as the CdS LD EU 10 ans, but - as I said - the language used suggests it is something different - subtly different perhaps, not different in any practical way perhaps, but different.
It doesnât help that there are at least three terms - carte rĂ©sident, carte de sĂ©jour and titre de sĂ©jour. Are these interchangeable or is there some subtle difference between them.
Thanks @anon87147852 for that up-to-date HMG overview of the various Brexit end-games and their consequences for some of us, maybe.
My general feeling (of misgivings slightly exaggerated by recent shenanigans in Westminster) is that if everything goes pear-shaped for Brits in the EU the blame will be placed at the door of the Brussels bureaucrats for not playing fair and reciprocal, typical of your garlic-guzzling surrender-monkeys (I know that last attribution is an American jibe) . 
Just have to wait and see, eh?
Woops apologies David - I hadnât seen your previous post - Iâve removed my duplicate.
I wish youâd posted it earlier, it took me ages to work out how to copy a link that wasnât just for mobile devices.
I guess what would be great is if someone (âŠanyone out there ???) could post a pic of their âpermanentâ CdS so that we can compare it with mine (pictured at post #18).
I maintain that the 10 year CdS IS the permanent one. My prefecture advised me that the âsĂ©jour permanentâ status (indicated on my card) was valid for life but that the card itself needs to be renewed once every 10 years (chip, photo updated etc). Makes complete sense to me (like a passport) but then I have been known to loose the plot on ocassion !
Someone out there must have one of these elusive âpermanentâ cards - come on, show yourselfâŠ
Makes perfect sense to me too
Sorry Simon canât show you mine, donât have one ! 
Just checked the 2 cards I do have. The first one says Communaute Europeene Carte de Sejour and was valid 5 years.
The second one says Titre de Sejour and was also valid for 5 years.
Modesty (or rather the thought of shocking anyone) forbids me to post a pic 
I really didnât think that this was that type of website!
Then who is that very good looking lady on your picture 
Itâs what you make of it Mat !
