You might need a certificate of custom law (certificat de coutume) if you’re getting married in France.
You should check with the local Mairie to confirm whether you need this or not.
There’s more information on getting married in France on our Paris Embassy website.
If you live overseas you can obtain a certificate of custom law through your nearest British consulate.

If your certificate is to be returned to you in the UK, please enclose two self-addressed, pre-paid special or recorded delivery envelopes for the safe return of your documents and certificate.
However, if your certificate is going to be sent to an address in France and not your address in the UK, you will need to send one special delivery envelope for the return of your documents and one addressed (not stamped) A4 or C5 envelope for the Certificate of Custom.
We’ll return your documents and send you an acknowledgement letter within 20 working days.
The application will then be sent on to our Embassy in Paris who will issue you with a certificate.
The certificate will be in French and will be valid for six months prior to your marriage, though you should check this with your Mairie.
You should check with the local Mairie in case you need the certificate to be issued sooner. If this is the case, please include a note saying so.

Please take care to fill in the correct application form with full information, and to submit your application with all documents requested allowing good time for the application to be processed and your certificate to be returned to you (N.B.
