Create a space from the Spaces tab and invite each family member. As everyone joins and picks what to share, the space builds into one view of the family's money: a combined total, a breakdown by instrument type (bank balance, NPS, cash on hand...), and a per-member view of what each person contributes.
Two things to know today: sharing is per-member and per-instrument, so each person stays in control of their own data; and spaces show high-level values only - individual transactions and portfolio detail stay private to each member.
