Yes my friend is going through a divorce and he has 2 kids he wants to have full custody of the kids. He asked me for advice but I do not have any kids of my own how does he go about fighting for full custody of the kids?

First please pay more attention to posting instructions. There is a sticky note on the top of the Children's forum where you posted that directs legal questions to the Family Law forum where I moved this too.

There is a simple answer to his question; get an attorney!

Your question is way too broad and vague for us to answer, Without knowing the reasons and details of the divorce, the location of the family, the ages of the children, etc. there is no way for us to offer any advice.
