When preparing an envelop for postal delivery to a male physician and his spouse, there are several styles that are proper. The oldest and most formal style is:
Dr. and Mrs. Martin Jones
or
Dr. and Mrs. Jones
Because referencing the wife by her husband's full name this way is very annoying to some people as a vestige of female secondary status in a marriage, an acceptable alternative is:
Dr. Martin Jones and Mrs. Mary Jones
or, if less formality is acceptable:
Dr. Martin and Mary Jones
or, with even less formality:
Martin and Mary Jones
Remember that is some regions, a physician need not be called "Doctor" in all circumstances, especially when the practice of medicine is not a major part of why you are addressing him or her.
Just by Mr & Mrs , or by their professional titles , if any.
Typically, if one spouse "outranks" the other one, that spouse is listed first (if both are of the same rank, then traditionally the male "outranks" the female, though nowadays either way is usually considered acceptable). For example: Dr Mabel Smith and Mr Hubert Smith If they were both doctors, then it would traditionally be Drs Hubert and Mabel Smith but if you know her a lot better than you know him listing her name first probably wouldn't be considered horribly wrong.
