In my experience, one should never sign anything unless all the bits and bobs are well understood and agreed.
Once upon a time, I was overcome with enthusiam and silly enough to sign something without fully reading and understanding … but only the once… never again.
Marriage register? 
naughty boy… 
never regretted our whirlwind romance… not for one second… 
Well, if it doesn’t turn up until 24 hours before the CdV then I think there may be some delays. 
My understanding is that you will have to arrange for any additional clauses to be written into the compromis.
When we were in the process of buying our house, the diagnostics revealed that the gas CH boiler was unsafe and it was condemned. We managed to get a clause inserted into the CdV stating that a new replacement (at the sellers’ expense) was mandatory.
I therefore advise against signing anything until you have read and understood the diagnostic reports plus the costs and timescales of rectifying any issues.
I would n’t have too much confidence in Leggetts. We found their service to be mediocre at best, and once the purchase had been completed they were totally uninterested in other issues that arose.
Have you asked where it is? So many times in France I have been huffing and puffing about something that I would expect to have been told - only to find that it had been done/sent/prepared but nobody said so!
The dossier of diagnostics may well be sitting on the notaire’s desk….
(2 examples from yesterday….had phoned local firm to arrange for a shutter repair, to be told by secretary “he will phone you”. No sign for days so popped into shop yesterday. Same secretary “oh he’s off sick and no idea when he’ll be back”.
Then had asked for a medical certificate from health centre…”we’ll phone you when doctor has signed it”. Popped in there too and it was waiting for me, dated over a week ago! )
Also take into account that its better to have a DPE(Diagnostic de performance énergétique)dated on or after July 2021 as the criteria are assessed differently and probably not as favourably as before this date.(although the ones done before are valid for three years)Apparentlly quite a few owners who have say E or F ratings now are trying to offload their properties now as they could easily become G under the new criteria.
Having said this no problem I would think if there is a goodish rating nowABC or if you intend to do work to improve insolation on your new property anyway
Thanks Jane, I did raise the question with the agent a couple of days ago, but she hasn’t replied yet. It may well have been done and is waiting somewhere, but we just need time to review and understand.
Now I may be showing my ignorance, but is there a legal/tax reason why a home with lower rating is a problem? The house is oldish - I should guess late 19th/early20th century, though not especially old - so isn’t going to be cavity insulated or anything special, but that doesn’t make any difference as far as we are concerned unless there’s some kind of external factor.
In a wider sense I care that the house isn’t going to be especially poor, but having been in there in cold weather (frosty outside - it was not cold indoors, and was plainly not lived in) it will be fine. Roof has been insulated, and the loft space is a single large room.
Eventually you won’t be able to rent houses with F and G ratings…
Have you raised the issue with the Notaire? As Jane did mention “it was waiting for me, dated over a week ago”
I’m not sure we have their contact information yet - perhaps I’m (unfairly) trusting the agent too much.
I personally would get the agent to divulge this information, They will give it if they are serious about earning some money. When we bought our house, the agent (not leggett) gave me the whole info packet without asking. As the Notaire is also on the council here, the whole sale was done and dusted within 4 weeks.
This could well be the case…… if you know the name of the notaire get in touch with their office and ask their secretary. Phone calls, not emails which they rarely read!
Please trust your instincts and delay signing. We had a diagnostic report that highlighted electric issues that required immediate attention but we were told by the agent (Leggett) they were not deemed an issue before signing the compris. We pulled out of the deal.
Also, the diagnostic report is very lengthy and ALL in French. You need to allow time for translation and understanding.
I’ve been through the diagnostics a couple of times while looking at other properties, and even in French, thanks to the use of pictures it’s not hard to figure out the bigger issues. But it does take time, you’re absolutely right.
The notaire will not draw up the Compromis de vente until he/she has 1. a copy of the diagnostics and CPE and 2. the latest SPANC report relative to the septic tank/mains drainage.
You could just go to the Notaire’s office and ask a secretary for a copy of these two documents … or tell the agent that you want them sent to you in PDF form asap … or you pull out of the deal.
Vendors who wait until the last minute before getting the diagnostics done (or revealing them) are often up to no good and intent on hiding something (usually dangerous electrics).
I see this often - especially when it’s vendors selling to a non-French buyer who they assume will not even bother reading the 84-page document!
Diagnostic due to arrive tomorrow afternoon. 
Does the property have a fosse or is it on mains drainage?
