No. There are ways that the business can protect itself for various events. For example, I was a founder in a business years ago. We included clauses in the stock buy-back agreement that could be triggered upon various events (death of a partner, divorce, etc.) Normally, those kinds of clauses ensure that the non-partner-spouse gets the value of the business owed to him/her, but loses decision-making control of the business.
