Skimming through the posts I was hoping to see some guidelines on pre- / post-divorce steps to take but haven't seen much, other than the usual "you should join a gym!" Is there some kind of FAQ for this subreddit?

Two simple questions from the top of my hat:
1) Is there a point to retain a lawyer at all? At a HCOL area in California I see basic rates listed around $20,000. If all the attorney does is write down a 50/50 split then why would I pay the extra $20k on top?

2) Use a mediator instead of a lawyer? Yes? No? Maybe?
