Our family business has been in an open estate for 10 years now. The business was left to myself and 3 siblings with equal shares (s-corp). All four of us work in the business. The estate administrator is a lawyer. Here's the problem, the shares were distributed and there was never any provisions made for a buyout for retirement, or wanting out, etc., I would like to be bought out, but the other three won't buy me out and say they don't have to because there's no buyout agreement. There is never an annual shareholders meeting, etc.,This has been very frustrating, and I'm wondering how the estate lawyer could issue shares without drafting an agreement for a buyout, knowing full well that eventually shareholders need to sell, etc., What are my options, if any.
