Across the United States, families are entering the largest wealth transfer in history, with an unprecedented $124 trillion projected to cross generations through 2048. Yet even affluent, financially-sophisticated households are unprepared. Many assume they have the right advisors, plan, or understanding of family intentions. But as Andrea Baumann Lustig demonstrates in Legacy on the Line, the greatest threats to a family's legacy aren't just the obvious ones like investment risk and taxes, they are the blind spots people don't know they have. These deeply held, but often incorrect, beliefs about money, advisors, investments, heirs and philanthropy can limit growth, increase risk, fracture families, and jeopardize even the most well-intentioned plans. Drawing on three decades of serving affluent clients, Legacy on the Line provides a structured approach to wealth management and transfer. It shows readers how to evaluate their advisor relationships, strengthen planning and communicate effectively with heirs to build legacies rooted in clarity, intention, and resilience. Through real-life client stories, Baumann Lustig reveals how the wealthy often sabotage their own plans -- relying on unexamined advisor relationships, sidestepping inheritance conversations, and overlooking the emotional heart of legacy. Legacy on the Line helps families rethink these habits and build a more intentional approach to wealth--one that reduces conflict, deepens connection, and helps create lasting impact across generations. Written for high-net-worth baby boomers, Gen Xers, and small business owners navigating the complexities of wealth transfer, Legacy on the Line speaks to both those managing their own assets and the advisors who guide them. This practical guide exposes the myths that derail even sophisticated families and offers the clarity and direction needed to align advisors, protect hard-earned wealth, and build legacies that preserve values across generations.
