After the salutation of a business letter, the correct punctuation to use is a colon.
Use the name of the person who wrote the letter, and write a formal letter. Use the salutation "Dear Mr. ____" or "Dear Mrs. _____" as a salutation.
To Whom It May Concern:
Dear Doctor Ben Corliss
Date, salutation, body, closing, enclosure
addressing attorney and wife
Depends on whether you wish to be kind, or offensive, right?
Mr and Mrs would be proper. Attorneys are typical written to as Mister.
Dr. and Mr. Steve Smith
The correct salutation for a judge in a letter is "Dear Judge [Last Name]." If you are addressing a higher court judge, you may also use "Your Honor" as a respectful alternative. It's important to maintain a formal tone throughout the correspondence.
Desmond Tutu was a Bishop, so the correct salutation would be, "Your Excellency".
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". If you are not an attorney, then the appropriate salutation always is 'Cher Maitre' or simply "Maître".
