Where children are involved, who gets custody is a significant aspect of a divorce. Fights over custody can get very ugly. The first problem is who gets custody and the nature of the custody.While historically, preference is always given to the mother, in today’s world that is not a given. Serious fathers can fight for shared custody and in certain cases even full custody. How and why can get very complicated and a parent in such a situation needs an advocate, someone who knows the law and can convince a judge of the merits of their arguments.
