Hi annie,
Are you currently separated or divorced? As i understand it your husband has taken all the assets. Normally upon separation parties are requried to first try to reach an agreement as to how their property will be separated, however if you cannot agree, you can apply to the court for financial orders regarding the division of your property and assets between you and your husband and also spousal and child maintenance. It doesn't matter that everything is in his name. You will be at least entitled to some portion of it - depending on what the court believes is fair in the circumstances.
Have a read of some of the other threads on this site about property settlements.
You will likely need to get some legal representation. I would speak to legal aid or a community legal centre for further information.
