Divorce and Your Will: Why Separation Should Prompt Immediate Estate Planning

Divorce fundamentally alters your estate planning landscape, yet many separating couples fail to review their Wills until it is too late. In England and Wales, whilst divorce does not automatically revoke your Will, it triggers significant legal consequences that can leave your loved ones vulnerable and your final wishes unfulfilled.

How Divorce Affects Your Existing Will

Under Section 18A of the Wills Act 1837, divorce creates a legal fiction whereby your former spouse is treated as if they had died on the date your decree absolute was granted. This means any gifts or bequests left to your ex-spouse in your Will automatically fail, and any appointment of them as executor or trustee becomes invalid.

However, the Will itself remains valid. This creates a dangerous situation where parts of your estate may now be distributed as if you had died intestate, potentially passing to unintended beneficiaries rather than reverting to your other named beneficiaries.

The Critical Timing Issue

If either party dies before the final order of divorce is granted, the marriage remains legally valid. In these circumstances, divorce proceedings automatically end, the surviving spouse may still benefit under the Will, and they retain rights under intestacy rules and the Inheritance (Provision for Family and Dependants) Act 1975. This makes it essential to review your Will as soon as divorce proceedings begin, rather than waiting until they are finalised.

What Happens If You Do Not Update Your Will

Failing to update your Will after a divorce can lead to unintended and potentially devastating consequences. Because your ex-spouse is treated as having predeceased you, the portion of your estate intended for them may not automatically pass to your other named beneficiaries.

Instead, that share could be distributed according to intestacy rules, which prioritise blood relatives in a strict order. This means your children from the marriage might inherit differently than you intended, or worse, distant relatives you never meant to benefit could receive part of your estate.

The Risk to Your Children and Dependents

Without proper estate planning following separation, your children face particular vulnerability. If you remarry without updating your Will, your new spouse could inherit your entire estate under intestacy rules if it is worth less than £322,000, potentially leaving your children from your first marriage with nothing.

Blended families face even greater complexity, as step-children have no automatic inheritance rights under intestacy. Without specific provisions in your Will, step-children you consider family may be excluded entirely.

Lasting Powers of Attorney and Divorce

Divorce not only affects your Will, but it also impacts any Lasting Power of Attorney (LPA) you have granted. Once your divorce is finalised, any appointment of your ex-spouse as your attorney is automatically revoked.

However, during the separation period before the decree absolute, your existing LPA remains valid. If you become incapacitated whilst divorce proceedings are ongoing, your ex-spouse retains authority to make decisions on your behalf as specified in the LPA document. This creates a significant risk during what can be a lengthy divorce process, making it advisable to appoint a new attorney immediately upon separation.

The Effects of Remarriage on Your Will

Remarriage creates an entirely different legal scenario from divorce. Under Section 18 of the Wills Act 1837, marriage or civil partnership automatically revokes any existing Will unless that Will was specifically made in contemplation of marriage to your new spouse.

This automatic revocation catches many people unaware, particularly those entering second marriages with children from previous relationships. If you die after remarrying without making a new Will, your estate will be distributed according to intestacy rules, which strongly favour your new spouse over children from earlier relationships.

Estate Planning for Blended Families

Blended families require particularly careful estate planning to ensure all children are protected. Standard “mirror Wills” where each spouse leaves everything to the other can be disastrous, as the surviving spouse may later change their Will to benefit only their own biological children.

Protective measures for blended families include establishing trusts that ring-fence assets for children from first marriages, making specific bequests to each child, and considering life interest trusts that give your new spouse the right to live in the family home during their lifetime, whilst preserving the capital for your children. Joint property ownership structures also require careful consideration, as property held as joint tenants automatically passes to the surviving owner regardless of Will provisions.

Separation Without Divorce: A Dangerous Legal Limbo

Many couples separate without obtaining a formal divorce, either for financial reasons, religious beliefs, or simply procrastination. However, remaining legally married whilst separated creates significant estate planning risks.

If you die whilst separated but not divorced, your spouse retains full spousal rights under intestacy rules. They will inherit at least a portion – and possibly all – of your estate, even if you have been separated for years and have no intention of them benefiting. Your spouse could inherit the entire estate if it is worth less than £270,000, or receive the statutory legacy plus half the remainder if you have children.

Can a Separated Spouse Contest Your Will?

Until a decree absolute is granted, a separated spouse remains entitled to contest your Will under the Inheritance (Provision for Family and Dependants) Act 1975. Separated spouses who can demonstrate financial dependency or that they have not received reasonable financial provision may successfully claim against your estate.

The courts consider various factors, including the length of the marriage, contributions made by both parties, and the needs of all beneficiaries. This means even a well-drafted Will can be challenged by an estranged spouse who remains legally married to you at the time of your death.

Taking Action: Steps to Protect Your Estate

Separating couples should take immediate action to protect their estate and ensure their wishes are honoured. First, review your existing Will with a qualified solicitor to understand how divorce will affect its provisions. Second, prepare a new Will that reflects your current wishes and family situation, explicitly excluding your former spouse if that is your intention.

Third, revoke any Lasting Powers of Attorney granted to your ex-spouse and appoint new attorneys you trust. Fourth, update beneficiary nominations on pensions, life insurance policies, and death-in-service benefits, as these pass outside your Will. Finally, consider using trusts and other protective structures if you have children from previous relationships or complex family dynamics.

Frequently Asked Questions

Does divorce nullify a Will in the UK?

No, divorce does not nullify or revoke your Will in England and Wales. Your Will remains valid, but Section 18A of the Wills Act 1837 treats your former spouse as if they had died on the date of your decree absolute. This means any gifts to your ex-spouse fail, and their appointment as executor or trustee is invalidated, but the rest of the Will continues to operate.

Do you need a new Will after a divorce?

Whilst not legally required, making a new Will after divorce is strongly advisable. Although your existing Will remains technically valid, the automatic removal of your ex-spouse as beneficiary and executor can create gaps in your estate plan that result in unintended distributions. A new Will ensures your estate is distributed according to your current wishes and that you have appointed suitable executors and guardians for any minor children.

What impact does divorce have on a Will?

Divorce causes any appointment of your former spouse as executor, trustee, or guardian to be automatically revoked. Any gifts or bequests to your ex-spouse also fail, with those portions of your estate potentially being distributed as if you had died intestate rather than passing to your other named beneficiaries. However, the remainder of your Will continues to operate according to its terms.

Can a divorced spouse still be an executor?

No, once your decree absolute is granted, your ex-spouse automatically loses their appointment as executor or trustee under Section 18A of the Wills Act 1837. You will need to appoint a new executor in an updated Will. However, if you die before your divorce is finalised, your spouse may still act as executor because the marriage remains legally valid until the decree absolute.

Can a separated spouse contest a Will?

Yes, a separated spouse who remains legally married to you can contest your Will. Until a decree absolute is granted, your spouse retains the right to make a claim under the Inheritance (Provision for Family and Dependants) Act 1975 if they believe the Will does not make reasonable financial provision for them. The court will consider factors including the length of the marriage, financial contributions, and the needs of all parties when assessing such claims.
