Wealthy families usually have good intentions when it comes to estate planning, but many still get it wrong. The result? Higher taxes, unnecessary costs, and wealth that doesn’t end up where it was intended.
At first glance, it doesn’t make sense. Families with millions in assets, access to advisers, and the ability to plan ahead should have estate planning nailed. Yet time and again, we see mistakes that cost hundreds of thousands, sometimes millions.
Why?
1. Overconfidence
Wealth often breeds the assumption that “we’ve got it covered.” A will drafted years ago, or advice taken once, is treated as permanent. In reality, tax rules, family circumstances, and even your own wishes evolve, but the paperwork is left behind.
2. Complexity for its own sake
Some families are sold complex trust structures or Family Investment Companies that look impressive on paper but add little practical benefit. Complexity is often confused with sophistication. The best plans are usually the simplest.
3. Poor communication
Estate planning isn’t just about money; it’s about people. Failing to explain your intentions to children or executors can cause resentment and disputes. Surprises in wills are one of the biggest triggers for family fallouts.
4. Ignoring tax changes
The UK tax landscape shifts constantly. Reliefs are capped, thresholds frozen, and new rules introduced. A plan that worked in 2010 may be obsolete, or even counterproductive, in 2025.
5. Focusing on tactics, not strategy
Families often focus narrowly on one aspect, a trust, a pension, or property, rather than seeing the bigger picture. Estate planning isn’t about individual tactics; it’s about how everything fits together.
Bringing it together
Wealthy families get estate planning wrong not because they don’t care, but because they underestimate how often it needs reviewing, and overestimate the power of “clever” structures.
The families that get it right keep things simple, review regularly, and focus on outcomes: less stress, less conflict, and more wealth passed smoothly to the next generation.
