Mediation is not recommended where there has been abuse. I have had a couple of sessions and he is not playing ball. Won’t provide essential paperwork etc. I have just started to look into arbitration but I think this is also something that you both have to agree to do. I think it works out cheaper than court and the person can make decisions for you (again I think). I don’t know anyone who has done this though.
I hope you find something suitable and I would also be interested to hear what others think as there is a lot of knowledge and experience on this forum! 🙂 Good luck.
