Hello Legal Eagles,

I am 46 year old. My wife is schizophrenic, from before marriage. I have been taking care of her, to the point that i lost my job and exhausted my savings. She even beats me up. Her relatives do not want to look after her owing to her aggressive and violent nature. They insist there is nothing wrong with her, although she has this mental problem.
From the legal point of view, what precautions should i take to protect myself from legal trouble, if she does self harm or harms some random person?
