Recently separated after 22 years. Own a business together, both have equal shares with a 3rd person having 10%. We are all directors. The business has been his idea from the start and I joined primarily to do finances but with a very part time role. I am not an expert in the area of business at all. He has emailed me today to say he is resigning as director and all legal and financial and operational responsibility is mine but as a shareholder he still wants equal dividend. I am in complete shock and have no idea what to do.
