I think an atty, not a mediator, is who you need to run the papers by. A mediator only works with couples who are divorcing on a non-contested basis, who are in broad agreement (no fight for custody, for example), and just need to negotiate teh dollar amounts, visitation schedule, etc.
I would seek the counsel of a good family law atty, preferably one who specializes in "men's rights" and paternal custody issues. You may get one to take an hourly rate from you to review the papers, instead of a large retainer that they would want if and when you definitely want to pursue divorce.
