British citizen marrying Tunisian citizen

Good afternoon everyone.

I am a British woman planning to marry my Tunisian fiancé this year in Tunisia. I am divorced.

Ii know I need  to get a verified certificate of no impediment from the British Embassy.

Please  could anyone advise which other documents are required by the Tunisian side and do they all need to be translated and the translated documents also verified at the British Embassy.

Many thanks in advance for your help and advice
