The proper way to list a husband and wife when acknowledging them in a program would be 'Mr. and Mrs. Smith.' You might also say 'Dr. and Mr. Smith' or 'Jane and John Smith'.
Dr. and Mr. Smith
The husband's name is listed first.
He can list but to sell it she will have to sign the paperwork.
Major and Mrs . . .
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.
doesn't matter
Like the words mom, dad, uncle, etc, wife would be capitalized if it is used as a proper noun, like a name. If it is not a proper noun, it is not capitalized. For example, "Wife, bring me my slippers" vs "I would like my wife to bring me my slippers"
Addressing a Mayor and his wife: Mayor & Mrs. John Smith
Dear Mr. John and Rev. Sally Smith,

The ex husband should come alone (without his girlfriend or second wife) and sit on the side of his ex wife's family. If you have a girlfriend or you're remarried it would be in poor taste to bring your mate to your ex wife's funeral.
