I have asked to the French embassy and other French citizens, and in all cases, the French embassy takes a very long time,
For time requirement please contact the French Embassy direct
If you are both citizens of france they will with some nice asking start the papers before hand and issue them when you arrive, then register the marriage, then report back to the French embassy who will certify the documents, but be prepared for a long long wait.
We have only done the legal for about 3 couples and it was many trips to the embassy and they seldom answer the phone and only will talk in French to French nationals….
French government is very strict about papers!
