Protecting Your Children's Inheritance From a Future Divorce

No parent wants to think about their child's marriage breaking down. But with roughly four in ten UK marriages ending in divorce, it's a realistic risk — and one that has a direct bearing on how you plan your Will. If you're leaving your home and savings to your children outright, there's a real possibility that some of it could end up being shared with a former son- or daughter-in-law rather than staying in the family.

The good news is that with the right planning, you can significantly reduce that risk. Here's what actually protects an inheritance in a UK divorce — and what doesn't.

Is an Inheritance Automatically Protected From Divorce?

Not automatically, no. When a marriage ends, the family court has wide powers under the Matrimonial Causes Act 1973 to divide assets in whatever way it considers fair, taking into account both parties' needs and those of any children.

The starting point is a distinction between:

• Matrimonial property — broadly, assets built up during the marriage through the couple's joint efforts (the family home, joint savings, pensions accrued together)
• Non-matrimonial property — assets one spouse brought into the marriage, or received later as a gift or inheritance

The "sharing principle" — the idea that matrimonial assets are typically split equally — generally does not apply to non-matrimonial property such as an inheritance. But there's a catch: if an inherited asset is mixed in with the couple's shared finances over time — paid into a joint account, used to pay down the joint mortgage, or treated as a shared family resource — it can become "matrimonialised" and lose that protection.

What the Supreme Court Just Confirmed

This distinction was significantly clarified in July 2025, when the Supreme Court handed down its judgment in Standish v Standish — the first case in almost twenty years to test these principles at the highest level. The Court confirmed that the sharing principle applies only to matrimonial property, and that pre-marital wealth, gifts, and inheritances remain non-matrimonial unless the couple's actual conduct shows they treated the asset as shared. Simply transferring an asset into a spouse's name, or holding it jointly, isn't enough on its own to change its status.

For families doing inheritance planning, this is a welcome piece of clarity: an inheritance left cleanly, and kept separate, has a stronger claim to staying outside the matrimonial pot than it might have appeared a few years ago.

 
Why "Needs" Can Still Get in the Way

Clarity on the sharing principle doesn't mean an inheritance is untouchable. Where the couple's matrimonial assets aren't enough to meet both parties' — and especially any grandchildren's — reasonable needs, particularly housing needs, the court retains the power to dip into non-matrimonial wealth to achieve a fair outcome. This is precisely where families with children tend to be most exposed: a young family's matrimonial assets are often modest, so an inherited house deposit or lump sum can end up being the only substantial pot of money available.

This is the gap that simply relying on "it's technically non-matrimonial" doesn't close — and it's where structuring the inheritance properly through your Will makes the real difference.

How a Trust in Your Will Can Strengthen the Protection

The single biggest factor is whether your child receives the inheritance outright or through a trust.

• Outright inheritance: your child personally owns the asset. It's simpler, but it's also squarely "theirs" for the court to consider, and it's easy for it to become mixed with joint finances without anyone intending that.
• Bare (absolute) trust: the child has a fixed, guaranteed entitlement. This offers little extra protection, since the courts tend to treat it much like outright ownership.
• Discretionary trust: your child is one of a class of potential beneficiaries with no automatic right to demand capital — trustees decide if, when, and how much they receive. Because your child doesn't own the assets outright, this is generally the strongest form of protection, though a court can still look at the trust as a "resource" if your child effectively controls it or regularly benefits from it.
• Interest in Possession / IPDI trust: commonly used for the family home, this gives a beneficiary the right to live in a property (or receive its income) without owning the underlying capital. It won't offer the same level of protection as a fully discretionary trust, but it still keeps the capital a step removed from your child's personal estate, which matters if the marriage runs into difficulty.

None of these are bulletproof — the court can still examine a trust's terms and how it's actually operated — but assets held in trust are, in practice, considerably harder to draw into a divorce settlement than assets left outright.

Making the Protection as Robust as Possible

A trust only works well if it's set up properly:

• Set it up early. Trusts created years before any marital difficulty are far more robust than anything put in place once problems have already started — a late change can look like a deliberate attempt to defeat a spouse's claim, and courts will treat it with suspicion.
• Use independent trustees. If your child effectively controls the trust as sole trustee, a court is more likely to treat the assets as theirs in substance, whatever the paperwork says.
• Discourage mingling. Inherited money paid into a joint account, or used towards a jointly owned home, can lose its protected status. This is worth discussing openly with your children.
• Keep records. Clear documentation of what was inherited, when, and how it was kept separate strengthens the case that it was never intended to be shared.
• Review your Will as life changes. A new grandchild, a child's remarriage, or a significant change in family wealth are all good reasons to revisit the structure.

What Doesn't Work

• Relying on a generic, off-the-shelf Will that leaves everything outright "to my children in equal shares," with no thought to how a future divorce might affect it
• Setting up protective structures only after a child's marriage is already in trouble
• Assuming that simply calling something a "trust" guarantees protection — the drafting and the way it's run in practice both matter enormously

The Bottom Line

An inheritance isn't automatically shared in a divorce, and recent case law has reinforced that principle — but it isn't automatically protected either, especially where a young family's needs are at stake. The strongest protection comes from planning the structure of your Will well in advance, with professional advice tailored to your family.
