"WARNING: California law provides that, for purposes of division of property upon dissolution of marriage or legal separation, property acquired by the parties during marriage in joint form is presumed to be community property. If either party to this action should die before the jointly held community property is divided, the language of how title is held in the deed (i.e., joint tenancy, tenants in common, or community property) will be controlling and not the community property presumption. You should consult your attorney if you want the community property presumption to be written into the recorded title to the property."
