Out of court, parents decide to try to reach an understanding. They end up rehashing problems in their relationship, and getting angry and sad.
They reach a settlement for shared custody.

Opinion: Movies are usually filmed in slice of life genre. That is, what the audience sees could actually be what you see in real life. Theater is usually directed in very dramatic absurd ways to reflect and heighten the emotional drama the character is going through. This movie combines 2 styles in a jarring way.
Also, the movie should be called "not meant for each other, and problems in communicating", because 1) they aren't a good match for each other. They'd be much happier if they had chosen other people to partner up, and 2) if she had been more incisive with what she wanted (job and city), and he had been more precise with what he meant (didn't make it dubious, leading her on), they would've reached an understanding which wouldn't have led them down this path.
Also, this movie is at least 1h longer than it needs to be. And the characters are bland and boring. Also, this is very chick-flicky, as she is being a B*** and doesn't get called on her BS (no sex, hacking computer, lying about the city change being temporary, lying about no lawyers, lying about custody, being jealous of the attention he's getting, making the dad be the bad father by giving too many presents to the kid, and not making the boy keep his responsabilities, drinking everyday, going to parties while he works, having sex with random people, taking the couch, relying on her mother for life expenses, while he doesn't have a parent to help him out, getting 2 dream jobs and an award, etc) (while he has to switch cities, spend a lot of money to pay for all the law suit, buy an apartment, guard her house, make the child be responsible, gets little love from wife and son, etc).
