Intestacy and a Separated Spouse: Your Estranged Spouse Inherits Everything

If you die without a will while separated but not yet divorced, your estranged spouse inherits your entire estate under UK law — as if the separation never happened. Only a final divorce order or a new will changes this.

The Risk at a Glance

No will, no children

Separated spouse inherits the entire estate.

No will, with children

Separated spouse takes £322,000 statutory legacy + half of remainder. Children split the other half.

Existing will leaves assets to spouse

Those gifts stand unless you make a new will. Separation does not revoke a will.

Urgent Steps on Separation

1

Make a new will immediately

Do not wait for divorce proceedings to complete. If you die intestate or with a will leaving everything to your spouse, the separation counts for nothing legally.

2

Update pension nominations

Pension death benefits typically pass outside the will under the trustee's discretion, guided by your expression of wishes. Contact your pension provider and update the nomination form.

3

Update life insurance beneficiary

Contact your insurer and change the beneficiary designation. Life insurance usually passes outside the estate.

4

Consider severing the joint tenancy

If you hold property as joint tenants with your separated spouse, sever it by written notice so your share passes under your will rather than by survivorship.

5

Review your LPA

If your LPA appoints your separated spouse as attorney for property and financial affairs, decide whether to revoke it.

Frequently Asked Questions

Does a separated spouse inherit under UK intestacy rules?

Yes — entirely. Under the intestacy rules in England and Wales (Administration of Estates Act 1925 as amended), a surviving spouse or civil partner inherits from an intestate estate regardless of how long the couple has been separated, provided the marriage or civil partnership has not been legally ended by a final order (decree absolute). Legal separation does not end the marriage. A couple living apart for 10 years who have not formally divorced remain married in law — and the 'surviving' spouse inherits as if they were still together. If the deceased left no children, the entire estate goes to the surviving spouse. If there are children, the surviving spouse takes the statutory legacy (£322,000 from November 2023) plus half of any remainder — the children divide the other half. This applies even if the deceased was living with a new partner at the time of death.

What is the only way to remove a separated spouse's intestacy rights?

The only way to remove a separated spouse's automatic inheritance right is: (1) Obtain a final divorce — the final order (formerly decree absolute) formally ends the marriage and immediately terminates all intestacy rights. The conditional order (formerly decree nisi) is NOT sufficient — the final order must be made; or (2) Make a valid will that expressly excludes the separated spouse. A will overrides intestacy and can specifically exclude the spouse from any benefit, or leave the estate to others. A separation agreement has no effect on intestacy rights — it is a contractual document between the parties and does not alter the laws of succession. Even court-approved financial consent orders do not affect intestacy rights unless they include an agreement by both parties to make wills.

What happens if I have a will but not a divorce — does separation affect my existing will?

Separation does not affect an existing will — the will remains valid exactly as written. If your existing will leaves assets to your spouse, those gifts stand despite separation, unless you make a new will or codicil changing those provisions. However: divorce does automatically affect an existing will. When a marriage ends by final order, under s18A Wills Act 1837: (1) any gift to the former spouse in the will lapses — it takes effect as if the former spouse had died on the date of the final order; and (2) any appointment of the former spouse as executor lapses. The will is NOT revoked — the rest of it remains valid, with the former spouse treated as having predeceased. This means: on separation, make a new will. Do not wait for divorce — you may die during the divorce proceedings.

Can my separated spouse claim more than the intestacy rules provide?

Yes. A surviving spouse who was separated (but not divorced) can make a claim under the Inheritance (Provision for Family and Dependants) Act 1975. Under s1(2)(a) IA 1975, a surviving spouse (including a separated but not divorced spouse) is entitled to 'such financial provision as it would be reasonable in all the circumstances to receive' — the full spousal standard, not merely maintenance. This is a higher standard than applies to most other claimants. In practice, a separated spouse who was financially independent and had been separated for many years may struggle to show entitlement beyond what the intestacy rules already provide. But if the surviving spouse was financially dependent on the deceased (e.g. paying a mortgage together, receiving maintenance), an Inheritance Act claim on top of the intestacy entitlement is possible. A will excluding the separated spouse does not defeat an Inheritance Act claim — it merely shifts the battleground to the courts.

What urgent steps should I take on separation?

On separation — before doing anything else about the divorce: (1) Make a new will immediately. This is the single most important step. If you die before divorce, intestacy gives your spouse everything (or the statutory legacy + half residue if you have children). A will lets you control where your estate goes; (2) Update pension expression of wishes — pension death benefits usually pass outside the will, so nominate the correct beneficiary with your pension provider; (3) Update life insurance beneficiary nominations — contact your insurer and change the nomination; (4) Consider lasting powers of attorney — if you had an LPA appointing your spouse as attorney, decide whether you want to revoke it; (5) Review joint tenancy — property held as joint tenants passes automatically to the survivor. You may want to sever the joint tenancy and convert to tenants in common so your share passes under your will. Severing a joint tenancy is a one-sided act — you can do it by written notice to the other joint owner.
