There is no 70% rule - improving outcome research in family wealth advising
The International Family Offices Journal
Vol. 6 - Iss. 4 pp. 33–38
In "There is no 70% rule - improving outcome research in family wealth advising", James Grubman provides a critical analysis of the Williams and Preisser longstanding assertion of a 70% failure rate of wealth transfer from the first generation to the second, plus other outdated statistics and proverbs including "shirtsleeves to shirtsleeves in three generations". He sets out parameters that could guide research in the field, hoping that family wealth advising will continue to evolve and support the longevity of today's complex diverse families.
