Proof of residence
To certify your address on your honour when asked.
The template text in French (the one on the document) — « Attestation de domicile »
The document starts with « Je soussigné(e) [your name], born on…, residing at…, » (I, the undersigned) … « atteste sur l'honneur que : »
je réside à l'adresse indiquée ci-dessus depuis le [date].
Cette attestation est établie pour servir et valoir ce que de droit.
Translation (to understand)
I have been living at the address given above since [date].
This statement is issued to serve whatever legal purpose it may.
When to use it? When an organisation accepts a sworn statement as proof of address.
Good to know: many procedures also require a document (bill, rent receipt): attach it if you have one.
