I am sorry to hear you are going through this, especially with such a young child. It must be very emotional and difficult.
I practiced family law in Utah and can give some perspective on this issue, although your lawyer would certainly know more about how it works in Michigan. First of all, I think it is about 95% of family law cases that settle without trial and there is a reason for that - not only is the system set up to incentivize settlement like in all civil cases to prevent the judge from having to hold a trial and the parties from paying for a trial, but because the issues are so personal the judges especially do not like to be the ones making them. In Utah, you would first have a settlement conference with a domestic relations commissioner. This person will have heard your motions in the past (temporary orders, etc.) and will have spent less than an hour reviewing your file and anything submitted by your lawyer. They are preparing to spend an hour or less with you for the purpose of narrowing down the issues. In my experience, this works as a b.s. filter, meaning that if one of you is being stubborn or unrealistic in your settlement attempts, the commissioner is going to say so and be annoyed if the party continues to hold that position unrealistically. The only issues that will go to the judge (and maybe another pre trial conference with the judge) and then trial are those that the commissioner certifies really need the court's intervention.
So, in preparation, I would tell you to think carefully about what it is your are asking for both in terms of property settlement, child support, and alimony (if any). Your lawyer no doubt can help you with this, but remember that you really benefit from settling now. Whatever you have already paid your lawyer thus far to prepare your case and take it this far, it is about to double if they have to prepare for and attend trial. If you really think what you are fighting over is worth it, be prepared to explain why to the commissioner/judge - not just expect your lawyer to, because they may address you directly.
Good luck and hang in there. I wish the best for you and your son.
