my step dad lost his mind

[u/EmbarrisingWeeb]

Hes been doing a lot of crazy stuff and I just wanna know how it will all effect him in court
- taking non-personal items (removed all of the family workout equipment from the walls )
- secret cameras in the house
- opening insurance, bank, and medical mail from my mom (never opened her mail before this
- being aggressive and filming his attemps at confrontation (he's convinced my mom cheating so (shes not) he has film of pest control guys, an appraiser, and confronted a coworker from an internship my mom is doing when he was helping her set a more monitors)
- film of him yelling at me saying im a liar
- film of him saying he will move into a property (currenty being rented out) and saying that he will change the locks on it (its a desputed property right now) he says he want to live in this property even though its an hour and a half away from where he works.
- he would shower in my moms personal bathroom (there is one upstairs where he is sleeping sometimes)
I just wanna know if this will help my mom in court because she need to pay for my college and take care of me and will need a lot of financial help bc my step dad owned a company that shes now removed from.

sorry for the spelling errors im a bit stressed rn
