Trust Duration: How Long Should a Charitable Trust Last?

When you set up a charitable trust, a legal arrangement where assets are held and managed for a charitable purpose. Also known as charitable foundation, it’s meant to keep giving long after the founder is gone—but how long is long enough? There’s no one-size-fits-all answer. Some trusts last 20 years. Others run for centuries. The key isn’t just legal rules—it’s whether the trust still serves real needs on the ground.

Trust duration isn’t just about paperwork. It’s tied to trust law, the legal framework that governs how assets are managed and distributed over time. In the UK and many US states, the Rule Against Perpetuities used to limit trusts to 21 years after a life in being. Today, many places allow trusts to last 100+ years—but that doesn’t mean they should. A trust designed to feed homeless families in 1995 won’t work the same way in 2025 if housing costs, food insecurity, or local policies have changed. The best trusts stay flexible. They don’t lock in rigid rules. They build in review periods—every 5 to 10 years—to ask: Is this still helping? Who’s being left out?

Many of the posts in this collection show how trust termination, the legal process of ending a trust when its purpose is fulfilled or no longer viable isn’t a failure—it’s a smart reset. A trust that funded after-school tutoring in a neighborhood that now has free public programs might redirect funds to mental health support instead. That’s not shutting down. That’s evolving. And it’s why trust duration isn’t about permanence. It’s about relevance. You don’t want a trust that outlives its usefulness. You want one that adapts before it becomes obsolete.

What you’ll find here are real stories from people who’ve managed trusts, ended them, or fought to keep them alive. You’ll see how trust duration connects to tax rules, community needs, and even legal battles. Some trusts fail because they’re too rigid. Others thrive because they’re designed to listen. Whether you’re setting one up, managing one, or wondering if yours should end—this collection gives you the practical, no-fluff facts you need to make the right call.
