A married couple a heated argument about their relationship. Maybe cheating is involved, or maybe one or both parties just can't stand the life they have together anymore. After a shouting match, one spouse storms out, but not before taking the kids with them. As an alternate scenario, they just leave, taking the kids and leaving a note while the other spouse is out at work.
The direction this trope ends up taking is largely dependent on what the motivations of the significant other are in this situation. If a woman is dealing with an abusive husband (regardless of whether he's abusive to her, the kids, or both), then she is in the right and the husband is a villainous character whom we are clearly supposed to be rooting against. If she is shown to be an unpleasant character who is very selfishly taking the kids away as a means of spiting her husband, the husband is usually the hero.
Another scenario involves relatively little animosity between the two at all — if the husband has gotten embroiled in a crazy conspiracy theory and the wife thinks he is losing his mind, then she can leave while Taking the Kids without any real hard feelings. Sure, the theory that Little Green Men are preparing to invade the planet might actually be true, but usually the husband and the audience can understand why the wife is skeptical and worried about the situation and don't hold it against her. In this situation, you can usually expect a happy reunion at the end once all the craziness is over with.
If the estrangement explicitly turns into a divorce proceeding, usually the wife either gains full custody or the lion's share of the joint custody arrangement — which makes this trope general Truth in Television, as custody cases tend to tilt toward the mother unless the father holds a very clear advantage (typically monetary, but sometimes emotional connection) over his ex-wife. Even then the usual outcome is not sole but joint custody.
For extra drama, you can make one of the two abduct the kids and take them far away from the other. To take this trope in the opposite direction (or for a different sort of drama), have them argue over who gets the dog instead.
It should be noted that in some countries, leaving and taking the kids counts as both spousal abandonment and kidnapping, regardless of their sex.
Closely related is Financial Abuse, where one (if not both) parties only want the kids for the financial benefits. Not to be confused with Custody Battle, which centers on the parents fighting for custody in court.
- In Kaguya-sama: Love Is War it's revealed that when Miyuki Shirogane's mother walked out on the family, she took his little sister Kei with her but left him behind, which seems to be the major reason he feels the need to prove his worth to the world.

It's a father/son story where the father still has no involvement with the kid (he appears for three minutes in the film at a Christmas dinner).

- The movie My One And Only, set in the 50s, starts with The Ditz wife catching her rich husband with another woman, so she hits the road with her two sons.

It also doesn't help that her new husband is a shrink (and a bit of an ass).

It's later revealed that Earl is the biological father of Dodge, but he and Joy did not know that because they conceived him at a Halloween party while wearing their costumes.
