The appropriate salutation depends on whether you also are a solicitor in your own country. If you are a female attorney too, then the appropriate salutation is "Chère Consoeur". However most French lawyers use the "Cher Confrère" salutation regardless of the gender of their interlocutor. If you are a man, you can write "Cher Confrère".
