<human>: Can you condense the text into three sentences or less?

My mom was diagnosed with schizophrenia in 2009 and has refused to be compliant with any sort of treatment despite multiple hospitalizations and pleas from her family members over the years. This last year, she has become physically violent towards my father, hitting him, kicking him, even punching him while he sleeps. I've personally witnessed this physical violence only once (provoked because we locked her computer account from internet access since she googles things that seem to exacerbate her hallucinations).

I admire my dad greatly, and things would be so much easier for him if he divorced her. But he's like Ned Stark, an honorable man, and refuses to break his marriage vow. He's worked his butt off my entire life to financially support our family while my mom has had a couple part time jobs here and there, never for more than a few months. I'm in medical school, and my brother is in undergrad. We've been struggling quite a bit financially the past few years. My mom is seriously considering divorcing my dad because she thinks he's satan (literally) and doesn't love him anymore.

So... What could be done to make sure she doesn't take him to the cleaners if this does in fact pan out?
<bot>: batshit crazy (no really) mom is physically and verbally abusive towards my father (basically a real life Ned Stark), and she wants to divorce him. How could I make sure she doesn't take him to the cleansers?
