How to deal with family members by marriage poses significant challenges to wealthy families. Should they be allowed to work in the family business? If so, should there be a ceiling on their authority (stock, voting rights, etc)? Do they have a seat/voice at family meetings? What if the only person in the rising generation with the skills to be involved in the family business is a child-in-law? What to do when a marriage is on the rocks (and the child-in-law has a role)?
