Can A Person Be Admitted To A Mental Hospital Without Their Knowledge Or The Permission Of A Family Member And No Testing Or Screening Being Done? I Have A Weird Situation Here I Guess.

You can only be committed to a hospital by a judge acting on the advice of a physician.

I agree with toasts answer.  If there is a mental condition then someone may have power of attorney over that person and can place them in a mental hospital for testing, etc.  Or a judge or a physician can also.  It depends on the mental condition and how severe it is I guess.  Good luck.

Sounds like you have grounds for a solid case indeed! In my state (Indiana) a person can be admitted against their will for a maximum of 72 hours for observation. A physician-psychiatrist evaluates and based on that recommendation can show proof the person is either dangerous to himself/herself or to others will the admission continue.

To be detained for a week without any evaluation sounds like an old script for a movie!
