Difficulty: Moderately Easy
Step1
Treat hyphenated names as one word. For example, Laura Smith-Johnson's last name is Smith-Johnson. Smith is not her "real" last name, and neither is Johnson. Smith-Johnson should be treated as one word and as one last name.
Step2
Capitalize both parts of the hyphenated name. It's Smith-Johnson, not Smith-johnson. Some computer systems aren't equipped to handle hyphenated names, and therefore you might sometimes see this kind of spelling-- but it's incorrect.
Step3
Alphabetize hyphenated names by the first letter of the first part of the name. Remember, it's one word. Smith-Johnson begins with an S, not a J.
Step4
Include the hyphen. Laura Smith-Johnson is not the same name as Laura Smith Johnson.
Step5
Use the whole name. Laura Smith-Johnson is not sometimes Laura Smith and sometimes Laura Johnson. It may be more convenient to use just half of the hyphenated name, but it's incorrect.
