The short answer
To track family net worth, give each person their own account, record ownership shares for joint and family assets so they are counted once, roll individual totals into a family view, and agree on what is shared. Add emergency access so someone you trust can see the picture if needed.
Count joint assets once
A home owned 50/50 should appear as half in each person's net worth and once in the family total. Ownership shares avoid both double counting and gaps.
Privacy is a feature
Not every account needs to be visible to everyone. A good family setup lets each person decide what rolls up and what stays personal.
Plan for the hard day
Families often discover accounts only after something happens. Emergency and legacy access, with a waiting period you control, makes sure the right person can find everything.
