Is cashing in a marriage near retirement a thing?

[tailfins]

I noticed some MGTOW commenters talk about some hypergamous women whose husbands were the best cash cow available during his prime earning years decide to grab half his retirement to go find another non-retired cash cow (aka husband). Is this a thing? If so, how common is it?

I stumbled across this while doing some basic research:

Interesting reading, the comments below, even more so:

Here is a rather interesting one:

Here’s something to keep in mind as you go through divorce: your state lawmakers write the laws about how divorce works in your state, not your soon-to-be-ex. So don’t take legal advice from him.
You are entitled to spousal support (California’s term for alimony) as long as you need it and he has the ability to pay it.

What does ability mean in this case? One can choose NOT to retire.
