Boy, I don't dare say anything to you - didn't mean to panic you. It would go a bit more easily if your new DH (dear hubby) was with you when you went to visit the Consulate. AFAIK it's not required, but as you saw on the website, you will have to bring certain documents with you if you go on your own .

You may want to check with the consulate if they will want you to bring his carte d'identité (i.e. the original) as well as a copy for their files. If they'll accept just the copy (or copies), have him handwrite on the copy an "attestation sur honneur" that it's a true copy of his carte d'identité - or ask the mairie (when you get married) to make a copy of his identity card and use their little stamp to verify that this really is a copy of his carte d'identité.

You don't get a carte d'identité until and unless you take French nationality. It's your husband's nationality they want to check - and for France it HAS to be a carte d'identité. A passport doesn't prove your nationality according to the French.

For proof of residence, he needs to give you a utility bill made out in his name (usually electric or telephone bill - usually fixed phone, but they'll often take a mobile phone bill as long as it's sent to him at the address where you will be living).
Cheers,
Bev
