Does separation affect a will?

No. Being separated, even for a long time, has no effect on your will. Until the divorce is finalised your spouse is still treated as your spouse, so they can still inherit and act as executor. You should update your will if you do not want this.

What happens to my will after divorce if my ex was the only beneficiary?

The gift to your ex-spouse fails, and that part of the estate passes to any substitute beneficiary named in the will. If there is none, it falls into the residue or passes under the intestacy rules. Making a new will after divorce avoids this uncertainty.

Q: Does divorce affect a will?

Yes, but it does not cancel the whole will. Once a divorce is final in England and Wales, your will is read as if your former spouse had died before you. Any gift to them fails and their appointment as executor or trustee is ineffective. The rest of the will remains valid.

Quick answer

Divorce does not revoke your will, but it changes how it is read. Once your divorce is final in England and Wales, the law treats your former spouse as if they had died before you: any gift to them fails and their appointment as executor or trustee no longer takes effect. The rest of the will stays valid. Separation alone has no effect at all.

Detailed explanation

Unlike marriage, divorce does not cancel your will. Instead, under section 18A of the Wills Act 1837, once the divorce or dissolution is finalised (the conditional order made final), the will operates as though your ex-spouse or ex-civil partner had died on the date the divorce took effect. This has two practical consequences:

Any gift left to your former spouse lapses and passes instead to a named substitute, or into the residue of your estate.
Their appointment as executor or trustee fails, so an alternative or substitute executor steps in.

Everything else in the will continues to apply as normal. Because gifts can lapse and fall into residue — or even into intestacy if no substitute is named — divorce can produce results you never intended. Making a fresh will after a divorce is the only reliable way to ensure your estate goes where you want.

Importantly, separation is different. Until the divorce is legally final, your spouse remains your spouse for the purposes of the will. A long separation, even an acrimonious one, does nothing: a separated spouse can still inherit under an old will and can still act as executor. If you are separated but not divorced, updating your will is essential.

Example scenario

Sarah's 2018 will left everything to her husband, with no substitute beneficiary. They divorce in 2025. Under section 18A, her ex-husband is treated as having died first, so his gift fails. Because Sarah named no alternative, that part of her estate now passes under the intestacy rules to her blood relatives — possibly not who she would choose. A new will would have settled it cleanly.

Action: Review your will both during separation and once the divorce is final. Don't forget to update pension and life-insurance nominations too — these pass outside the will.
