On the website, we see the sentence 'man sues his wife over ugly children.'
I would like to know the difference when we use 'for' or 'on' instead of 'over' in this sentence in meaning.
-
man sues his wife over ugly children.
-
man sues his wife on ugly children.
-
man sues his wife for ugly children.
Could you please explain the difference in meaning and usage.

It would be odd to say
It could mean a number of things:
But this would be an ellipses of: "I'm suing XYZ for (all the) children (who are the victims)."
You definitely cannot sue on (ugly) children.
(also impossible because any children of mine are beautiful)
But as @TRomano has pointed out in the comments, you can sue (someone) on the grounds of something. If an offence has been committed, you have the grounds = legal basis for a lawsuit.
The preposition over in the headline cited by the OP is the most suitable one:
The preposition is short for "on the question of", "in reference to", "concerning", "on the matter of", etc.
