How Do You Protect Your beneficiary’s Inheritance From Their Divorce?

• A discretionary trust rather than an outright gift, is the strongest structure for shielding a beneficiary from a divorce settlement.
• Courts have wide discretion under Matrimonial Causes Act 1973, Section 25, to include inherited assets if they have been mixed with joint finances.
• Inheritance is treated as a non-matrimonial asset in principle, but this does not mean it is automatically excluded from a settlement.
• A trust set up years before any marital difficulty is far harder to challenge than one created once divorce looks likely.
• A letter of wishes guides trustees without creating a fixed legal entitlement that a court could treat as a matrimonial asset.
• Keeping inherited funds in a trust, strengthens the case that the money remains non-matrimonial.

Matrimonial assets are built up during the marriage or intended for shared family use. They are normally divided between both spouses on divorce.

Non-matrimonial assets are owned before the marriage or received individually by one spouse, such as an inheritance. Courts generally try to keep them outside the division, unless they have been mixed with joint finances.

A discretionary trust gives trustees (not your beneficiary) full control over who receives capital and when. Your beneficiary has no fixed entitlement to any specific sum, only a potential interest, which is what usually keeps the assets outside the matrimonial pot.

A bare trust or disabled persons trust gives your beneficiary an immediate and fixed right to the assets. This offers much weaker divorce protection, because a fixed entitlement is exactly the kind of asset a court can attach.

No, inheritance is not automatically protected. Courts treat it as a non-matrimonial asset in principle, but they can bring it into a settlement if it has been mixed with joint accounts, used to fund the family home, or relied on to meet either spouse’s needs.

The court’s starting point under Section 25 of the Matrimonial Causes Act 1973 is fairness, not ownership on paper. If your beneficiary received their inheritance directly and it has been sitting in a joint account for years, or paid down the mortgage on the family home, a court is likely to view it as part of the pot available for division. The less that inheritance has been touched, the easier it is to argue it should stay separate.

A discretionary trust removes legal ownership from your beneficiary by handing control to independent trustees. Because your beneficiary holds no fixed entitlement, courts in England and Wales generally cannot treat trust assets as a resource available to a divorcing spouse.

There is an important exception. If the trust was set up for a married couple jointly, with the spouse also named as a beneficiary, a court may find it is a “nuptial” trust and use its powers to vary it as part of the settlement. A trust drafted for your beneficiary alone, with no role for a spouse or son-in-law or daughter-in-law, is on far stronger ground. Case law such as Charman v Charman shows that courts look closely at who actually controls a trust, not just what the trust deed says on paper.

Yes. A trust established years before any marital difficulty arises is significantly harder to challenge than one created once a divorce is already anticipated. Courts can treat a last-minute trust as a sham arrangement intended to defeat a spouse’s financial claim.

This is one reason many people choose to set up a trust during life time rather than writing into their will. A will trust only comes into existence on your death and therefore is not as effective as setting up a lifetime trust. Setting up a trust while you are alive can still make sense for other reasons, but it brings the inheritance tax nil-rate band of £325,000 into play, since transfers above it as of the 2026 to 2027 tax year are chargeable at up to 20 percent on entry.

A letter of wishes sits alongside the trust deed and tells trustees how you would like them to use their discretion, without creating a legal entitlement a court could attach. It carries no binding force, which is exactly why it does not weaken the trust’s protection.

You can use it to flag that a beneficiary is going through, or may go through, a divorce, and to guide trustees toward delaying distributions of capital until the settlement is finalised. Trustees are not obliged to follow it, but in practice, most do, provided the guidance is reasonable and updated as circumstances change.

Most settlers assume an inheritance is automatically off limits in a divorce because it was never intended for their beneficiary’s spouse. That assumption is the single biggest reason inheritances end up in the matrimonial pot. The moment inherited money touches a joint account or a joint mortgage, its non-matrimonial status becomes a matter for argument, not a matter of fact.

Structuring wealth properly protects it on more than one front. 19 out of 20 Bluebond clients legitimately pay zero inheritance tax, and the same discretionary trust structures that achieve this outcome are often the ones that hold up best if a beneficiary later divorces.

1. Does your will currently leave assets to your beneficiarie’s outright, or through a trust?
2. Would a discretionary trust for your beneficiarie’s, with no role for their spouses, suit your family’s circumstances?
3. Have you drafted, or updated, a letter of wishes that trustees can refer to?
4. If your beneficiary has already received an inheritance, is it sitting in a separate account in their sole name?
5. Have your trustees been chosen for independence, not just convenience?
6. Should your beneficiary and their spouse consider a prenuptial or postnuptial agreement alongside the trust?
7. Is your will trust properly reviewed against current Inheritance Tax Act 1984 rules and thresholds?

• Leaving significant assets to a beneficiary outright when protection from a future divorce is a priority.
• Waiting until a beneficiary’s marriage is already in difficulty before setting up a trust.
• Letting a beneficiary mix an inherited lump sum into a joint account or use it to fund the family home.
• Naming a beneficiary’s spouse as a trustee or a beneficiary of the same trust.
• Assuming a bare trust offers the same protection as a discretionary trust. It does not.

Generally yes, inheritance received before or during the marriage is treated as non-matrimonial in principle. The protection weakens the more it has been mixed with joint finances or relied on to meet the family’s needs, regardless of when it was received.

A well-drafted prenuptial or postnuptial agreement can explicitly exclude inherited assets from the matrimonial pot, and courts usually uphold agreements freely entered into on both sides. It works well alongside a trust, but on its own it is not automatically binding in the way a trust structure is.

The trust structure itself still applies, but trustees will need specialist advice before making any distributions, since a court may examine the trust’s assets as a resource available to your beneficiary during the ongoing proceedings.

Whether your beneficiary’s inheritance survives a divorce settlement usually comes down to decisions made years in advance, not arguments made after the fact. A discretionary trust set up in lifetime, paired with a clear letter of wishes and independent trustees, gives your family the strongest starting position. If your beneficiary’s marriage is already under strain, review your estate plan now rather than later.
