This document provides an overview of legacy giving and outlines a building blocks approach to establishing a legacy giving program. It defines legacy giving as conveying one's values through future charitable gifts. Legacy gifts can be as simple as changing a beneficiary form or more complex like a will or trust. While only 1 in 10 leave a gift to charity, legacy giving is an important opportunity as it has low fundraising costs and increases other donations. The building blocks approach promotes sustainable legacy giving through mission alignment, leadership engagement, identifying prospects, stewarding relationships, communications, and program planning.
