My friend is about to get a divorce and I have been helping him find out more.
Oh its the dissolution of the marriage legally
So it is a legal process? Like in court?
Yes terminating the marriage and reorganizing the legal duties and responsibilities
It sounds like a messy process. 
Yes it is because issues like alimony and child support and child custody are settled
My friend has kids so he will have to deal with that I am assuming, What else can you tell me so I can help him out?
legal process involves spousal support, child support , child custody, visitation and distribution of property, 
I see. He also has a house so that will have to be figured out too it sounds like.
that will fall under property division (who get its) and division of debt (who pays for it)
