We had our rdv at the Prefecture for 03 Allier on 22 August. Yesterday (28/9) I have a letter to return, with or without rdv, with the letter.
We went as a couple and as with everything I took our birth and marriage certificates. These were copied but no request for translations. They may not be on the required list, but it’s the only document to prove official change of name. Await husband’s letter!
