My husband of 20 + years inheritated 34 shares of stock from his parents business. Three other siblings share the rest of the stock. The two of us have been running the business for about 25 years. I am the secretary/treasurer/office manager...I do all the books. The stock certificate is in a joint lock box at the bank. He has 2 adult children from 2 previous marriages. Without a will how will the stock be devided?
