How to Address Invitations

I recently came upon this problem and was super confused on how to address an invitation to two doctors that are married but have different last names.

This is the information I found via The Knot

I hope this is helpful for you too!

If a wife and husband are both doctors,
the outer and inner envelopes should be addressed to:

"The Doctors Rosenthal."

It's that simple!

If they're married but have different last
names, list both names in alphabetical order on separate lines:

"Dr. Rosenthal" followed by "Dr. Schwartz".

If only one spouse is a doctor, list the
person with the professional name first:

"Dr. Kate Randolph Mr. Brian Randolph"
or "Dr. Kate Randolph and Mr. Brian Randolph"

(if it fits on one line).
