'Here's an example of how extremely legally restricted divorce was.'
'Nuh uh, here's the same example.'
Fuck off.
There's a legal framework for when you're allowed to kill someone. Under narrow circumstances - the state will tolerate it. Otherwise, they sure don't. The only reason nobody went to jail for an unregistered divorce is that there is no such thing.
And even then, surely some people went to jail for enabling divorce, when a cottage industry popped up to fabricate excuses. Because excuses were required. Otherwise: divorce was not legal. The state would not recognize it. Without a very specific reason, you could not legally get divorced.
