Many guardianship petitions are brought by well meaning people who are totally unaware of the ramifications of guardianship.
They usually have no idea that once a guardian has been appointed over a person, that person completely loses his/her liberty.
A guardian has enormous power over a person:
A guardian can decide where you live.
A guardian can sell your home without your permission and knowledge.
A guardian can change your will.
A guardian can charge fees, sometimes exorbitant.
A guardian can get a "commission" from your estate.
A guardian can decide how you will die.
The Ward has less rights than a death row inmate.
