Questions about alcoholism

My wife is an alcoholic and is wreaking havoc on the lives of me and our children. I see that alcoholism is one of the grounds for divorce.

What does it take to prove she is an alcoholic to the court?

If proven, does this mean divorce can be filed for immediately or is there still a one year separation period that has to happen?

Thanks.

Alcoholism is a ground for divorce from bed and board ( a judicially ordered separation), not an actual divorce. These actions are used to have one spouse ordered out of the home. For an actual dissolution of the marriage you will have to live separate and apart for one year and one day prior to filing.
