Whom / or Who?......
"Whom" is correct since there is no verb associated with it. "Who" needs a verb. That said, the title should read:
For Just Whom is this Divorce Good
Whom: Objective case. But to answer the question: All divorces are good for lawyers.
Whom is correct because it is always used in reference to a preposition (for in this case).
A good example is that we use "to whom" it may concern in official writing, and not "to who".
