What is the chance to get conservatorship for my 35 year old daughter who is an alcoholic .

It is very, very difficult to obtain conservatorship based on alcoholism or drug abuse.  Generally speaking, a person is eligible to be protected by a conservatorship/guardianship only if, due to a physical or mental illness, they are unable to provide for their own food, shelter or medical care or to manage their finances.  Getting a court to recognize alcoholism or drug abuse as a physical or mental illness seems to be a high hurdle.
