When we think about protecting family wealth, our minds often jump to tax planning or investment strategy. But increasingly, one of the biggest risks to long-term wealth isn’t markets or legislation, it’s relationships. With an estimated £5.5 trillion set to pass between generations over the coming decades, more families are asking a difficult but important question: how do we ensure that wealth stays within the family, even if life doesn’t go to plan?
Traditionally, conversations about protecting assets from a partner were associated with the ultra-wealthy, Hollywood celebrities or business magnates. Today, that mindset is changing. Ordinary families are taking a more pragmatic approach, recognising that love and money don’t always follow the same path. With around four in ten marriages ending in divorce in the UK, it’s no surprise that parents and grandparents are becoming more cautious when making substantial gifts.
One of the most noticeable trends is the rise in prenuptial and postnuptial agreements.
Far from being seen as unromantic, they are increasingly viewed as a form of sensible financial planning. Younger generations, in particular, tend to be more open to these conversations, often seeing them as a way to create clarity rather than conflict. While these agreements are not strictly legally binding in England and Wales, courts do give them significant weight, provided they are entered into properly, with full disclosure and independent legal advice.
At the very least, they help establish a clear understanding of what is intended to remain “family wealth” rather than shared marital assets.
However, agreements alone are not a silver bullet. Courts will always prioritise fairness, particularly where housing or financial needs are concerned. For example, a family-funded home may still need to be divided if it is the only way to meet both parties’ needs following a divorce. This is why planning needs to go beyond simple documentation.
Trusts are increasingly being used as an additional layer of protection. They can allow families to pass on wealth while retaining a degree of control over how and when it is accessed. Discretionary trusts, in particular, can be powerful, enabling trustees to delay or adjust distributions if a beneficiary’s circumstances, such as a fragile marriage, raise concerns. That said, trusts are not foolproof and come with complexity, cost, and ongoing administration, so they need to be carefully considered.
Ultimately, protecting family wealth is about balance. It’s not about expecting relationships to fail, but about recognising that circumstances can change. By putting thoughtful structures in place, families can provide support to the next generation while also preserving the integrity of what they’ve built, ensuring that wealth remains a source of opportunity, not unintended loss.
