I did some digging and found out he is 26 years old and he lives with his younger brother and younger sister (the house is in his father's name - the father does not live in town). His brother knows about his older brother's mental problems and is also very afraid for his younger 18-year old sister's safety. He wants to see his older brother get some mental help as the older brother is refusing any treatment. The younger brother simply does not know what to do and doesn't know where to go for help.
My girlfriend already got a restraining order, but I am now sympathetic to that older brother (and still afraid for her safety). I want to help this guy undergo psychological evaluation to determine how he can be helped.
From reading up on the topic, I believe that, since he is technically not an "immediate" threat to anyone, the correct body of law that would apply here is WIC Section 5200 (please see: [url=http://info.sen.ca.gov/cgi-bin/displaycode?section=wic&group=05001-06000&file=5200-5213]CA Codes (wic:5200-5213)[/url]).
Is there a sample form out there that I can fill out for this case? Is there anything else I should attach to the form? Where I would submit the form? Thank you!
P.S. I do apologize if this is the incorrect section. I've thought for a while and wasn't completely certain of the appropriate forum to put this under.
