Is my husband entitled to half of my earnings before I file for divorce?

My husband was physically, emotionally and economically abusive of me for most of our 15 year marriage. He left me jobless, homeless and penniless. Now I'm afraid to get a job because I read in a book about preparing for divorce, that he is entitled to half of all the money I make, and all of my savings. Is this true even in a domestic violence situation? If it is, how can I make money to survive and still protect myself from him?
