Prenuptial Agreements and Inheritance: Protecting Inherited Wealth on Divorce
Courts in England and Wales will give decisive weight to a fair prenuptial agreement freely entered into with full disclosure — making it a valuable tool for protecting inherited wealth. But they retain final discretion and the agreement must remain fair.

Frequently Asked Questions
Can a prenuptial agreement protect an inheritance from being divided on divorce?
A prenuptial agreement can significantly strengthen the protection of inherited assets — but it is not a guarantee. In England and Wales, prenuptial agreements are not automatically legally binding contracts. However, following the Supreme Court decision in Radmacher v Granatino [2010] UKSC 42, courts will give 'decisive weight' to a prenuptial agreement where: (1) it was freely entered into by both parties; (2) both parties had a full appreciation of its implications; (3) it is fair to hold the parties to it in the circumstances at the time of divorce. If these conditions are met, the court should uphold the agreement. Inherited assets are more likely to be protected if they are identified as 'non-matrimonial property' in the pre-nup and kept separate from the couple's joint financial affairs.
What is 'non-matrimonial property' and why does it matter for inheritance?
Non-matrimonial property is wealth that was not generated by the marriage — it includes assets brought into the marriage by either party, including inheritances received before or during the marriage, and gifts from third parties. English family courts have traditionally been more willing to exclude non-matrimonial property from division on divorce (White v White [2000]; Miller/McFarlane [2006]). However, if non-matrimonial property becomes 'mingled' with matrimonial assets — for example, an inherited sum used to pay off the joint mortgage — it loses its separate character and is treated as matrimonial. A prenuptial agreement can explicitly designate specific inherited assets or future inheritances as non-matrimonial property, and provide that they should be excluded from any financial settlement.
What conditions make a prenuptial agreement more likely to be upheld?
The Radmacher conditions and subsequent case law suggest the following: (1) Independent legal advice: both parties should have separate solicitors advising them before signing; (2) Full financial disclosure: both parties disclose all assets, income, and liabilities before signing — concealment is grounds to set aside; (3) Not signed under pressure: signed at least 21–28 days before the wedding, not at the last minute; (4) Not manifestly unfair: the agreement must not leave one party in a position of serious financial hardship — courts will not enforce an agreement that is 'unfair' at the time it is sought to be enforced; (5) Clarity: the agreement specifically identifies the assets being protected (including future inheritances if possible); (6) Review clause: the agreement includes provision to review on significant life events (birth of children, major change in assets).
Can a prenuptial agreement cover a future inheritance not yet received?
Yes — a well-drafted prenuptial agreement can include provisions covering anticipated future inheritances (for example, from elderly parents who have made their intentions clear). The clause would state something to the effect that any inheritance received by either party during the marriage shall be treated as non-matrimonial property and excluded from division. Courts have given weight to such provisions. However, the more speculative or large the anticipated inheritance, the more the court may scrutinise whether the agreement is fair — particularly if circumstances change significantly (for example, one party becomes the primary carer for children). For very large family estates, a combination of a pre-nup, a discretionary trust, and clear will drafting provides the most robust protection.
Is a postnuptial agreement equally effective at protecting inheritance?
Postnuptial agreements (made after marriage) are subject to the same Radmacher principles as prenuptial agreements — courts will uphold them if freely entered into with full disclosure and if they are fair in the circumstances. However, postnuptial agreements are subject to slightly greater scrutiny because of the duty of good faith in marriage, and because they may be entered into at a time of marital strain. A postnuptial agreement is useful if: (1) an inheritance was received after the wedding and the couple wants to formally designate it as non-matrimonial; (2) the couple did not make a prenuptial agreement and want to put protections in place now; (3) circumstances have changed significantly since the pre-nup was made (e.g. a new substantial inheritance). The same independent legal advice and full disclosure requirements apply.
Combine a Pre-Nup with a Properly Drafted Will
A prenuptial agreement works best alongside a will that routes inherited assets through discretionary trusts or bloodline protections. The WillSafe kit from £19.97 for England and Wales.
