Worried about my cousins

I found this website while searching the internet trying to find something that could help to save my younger cousins from a possible horrible life. This is sort of lengthy, but I need advice about how to help my younger cousins. My uncle and his wife have been experiencing marriage difficulties for the past three years. I am sure that it started out with "normal" unhappy marriage circumstances, however it has gone far beyond that. My uncle works two jobs, he is a police officer, and a part time landscaper. His wife does not work, and in fact just started to go back to college to under his funding to get a degree. Two years ago his wife got, what I would call addicted to the computer. She shortly after began speaking with a man that she met on the internet. These circumstances continued for the past year. Even after my uncle caught her red handed meeting this other man in a hotel, the emails continued and the meetings continued. This story involves four children, the oldest being eight, and the youngest being three. These poor kids have already suffered through continuous fighting and separating, and are now going to be faced with a messy divorce. My uncle recently filed for divorce, and has started meeting with a lawyer. Here is my reason for concern: his lawyer said there is no way that he could get custody of them because it is a mother's world. This upsets me so much because as there twenty year old cousin, I have watched their mother cause them to suffer. If she was unhappy in the marriage, she should have just left my uncle, not cheat on him. The addiction to the computer has also caused her to neglect the children. The school called the police station looking for my uncle because she never showed up to pick one of the children from school, another time, while she was watching them the cops were called because the children were found wandering a busy road. It has even led to the youngest child's doctor to say that the parents' problems at home are having an effect on her psychological well being. My uncle's lawyer said that a court would never give custody to a father that works two jobs, and when the mother appears to be giving primary care. I think this is ridiculous. My uncle is only working two jobs because she doesn't work at all. She is the one who had an affair and how can they assume she is the primary caregiver just because she is the one home with them. They can't see she doesn't do anything. My little cousins are hurting, and I don't know what to do. Do you think my uncle should have a new lawyer? Or does anyone have a suggestions I can give to him. I garuntee if custody is given to their mother, then my uncle, nor me, nor anyone else in my family will see these kids again. Please help me.

Any lawyer who says it's a mother's world isn't worth the retainer. It's still early enough in the proceedings to talk to an attorney who can help balance this mess out.
I personally receive e-mail from 30-40 parents, both dads and moms who thought they didn't have a chance, then were able to survive a divorce with the children in their homes. Being a police officer, small town or large, he should be in contact with other officers who were able to win a custody battle, as well as lawyers. I'd suggest that he stop the second job, in the event that he were to lose the primary custody of the kids. PS
