Very Nervous But Getting Out

After 10 years of marriage , I have finally made the decision to leave my verbally abusive husband. We have a young son and that is what makes me nervous. But I know he will be worse off if I stay in this marriage. My husband is a very good father but a horrible husband. I believe he is clinically depressed and has SERIOUS anger issues. Over the years, he has destroyed furniture, punched holes in the walls, and has even pushed me on occasions. I'm a good person & do nothing to provoke him. He gets angry at the smallest things. He is also a control freak. I feel that I cannot do anything without his permission. However, I am very concerned with our finances once I leave. The bank accounts are in his name only (I know, never should've let that happen...long story). My lawyer told me to make copies of any financial statements before I leave. I'm just afraid that my husband will empty out the accounts & leave me penniless. I'm not sure what rights I have regarding our money. We owned a house together for 8 years & I contributed to the mortgage during that time. I feel like I should be entitled to something. Does anyone have any additional advice?
