Your mother is not considered a natural heir, as you are expected to outlive her. And there is no need to 'disown' a child, you simply have to name them and say they don't get anything.

Yes, it is illegal for a mother to access her adult son's medical records without his permission.
The closest thing you could do would be to get a restraining order. Because he/she is a bro/sis you can not "disown". disowning refers to taking someone out of your will. if if you want to. you could do that in addition. but moving away would be the closest thing to "disowning.
Yes. You just have to write in your will that your adult child gets NOTHING.

In most countries, parents cannot legally disown their adult child in the sense of completely severing legal ties, such as disinheritance. However, parents can choose to have no contact or relationship with their adult child, which is not the same as disowning them in a legal sense.
No, I don't think so.
Yes. That is typically accomplished by disinheriting that child in your Will.
It would be best to consult with a family law attorney in your jurisdiction to determine the specific legal documents needed to disown your adult child. The process can vary depending on the laws in your state or country.
You can obtain a Protective Order against your son and have him evicted from the home (at least for a time).
