When families resist formal investment governance, the consequences often surface at moments of transition—after a liquidity event, during a generational shift, or amid growing complexity.

By outlining the five foundational building blocks of effective ICs, the piece offers practical guidance for families and their advisors seeking to improve investment oversight while preserving flexibility, trust, and long-term success.
