- ““Most families are only aware that they have one form of capital: financial capital,” says James E. (Jay) Hughes, Jr., an estate planning lawyer and family governance specialist in New York, author of Family Wealth: Keeping it in the Family. Hughes is a proponent of the four forms of family wealth: “A family must know whether all of its forms of capital are growing. Rarely in my experience do families measure their human, intellectual, and social capital. Frequently, members do not even recognize that they own these forms of capital.”” Wealth in Families Third Edition (Charles W. Collier) Page 8-9
