Fletcher: Greta, please! I'm on my knees in a $900 suit.
Miranda: That was incredible. Was it good for you?
Fletcher: I've had better.
Judge Stevens: Mr. Reede, one more word out of you, and I will hold you in contempt!
Fletcher: I hold *myself* in contempt! Why should you be any different?
Judge Stevens: It is only out of sheer morbid curiosity that I am allowing this freak show to continue.
Judge Stevens: How are we this morning, Counselor?
Dana: Fine, thank you.
Judge Stevens: And how about you, Mr. Reede?
Fletcher: I'm a little upset about a bad sexual episode I had last night.
Judge Stevens: Well, you're young. It'll happen more and more. In the meantime, what do you say we get down to business?
Max Reede: I wish, for just one day, Dad couldn't tell a lie.
Answer: First of all, she's not "on the hook" anyway...this is a divorce proceeding, not a criminal trial. And second, this film has multiple inaccuracies in its depiction of the legalities involved (see Legal Eagle's two-part analysis on YouTube for a very good rundown); the fact that no-one brings up fraud is the least of them. It's not important to the plot, so it is simply brushed aside, counting on us (the audience) not worrying too much about it, like so many other lapses of reality in comedy movies.
