When addressing a business envelope where the husband is Mr. and the wife is Dr., the proper way to format the names is to list the titles in alphabetical order. Therefore, you would address the envelope as "Dr. and Mr. [Last Name]." For example: "Dr. and Mr. Smith." This shows respect for both titles.
It should read: Rev.(Ret.) Mary & Mr. Smith
Dr. Mary Smith and Mr. James Doe
The same way you would if her husband were still alive. Even though a woman's husband has passed, she still retains his name.
