Estate Planning for Single People

Being single does not remove the need to plan; it often sharpens it. Without a spouse or civil partner, the intestacy rules pass your estate to a fixed order of blood relatives, and no partner, friend or charity you might have chosen can inherit unless you have made a will (gov.uk, as at July 2026, subject to change).

This guide is for anyone who is unmarried, whether single, cohabiting, widowed or divorced. It covers what happens if you leave no will, how a will puts you back in control, why a lasting power of attorney matters when there is no spouse to step in, and how inheritance tax works when you cannot rely on a spouse exemption. It forms part of our wider estate planning guide. Figures are current as at July 2026 and are subject to change.

Why does estate planning matter more for single people?

Because the safety nets that married couples take for granted do not apply. There is no spouse to inherit automatically, no partner with an automatic right to make decisions if you lose capacity, and no transfer of unused tax allowances between you. For single people, the documents you sign are often the only thing standing between your wishes and a default set by law (gov.uk, as at July 2026, subject to change).

What happens to a single person's estate with no will?

It passes under the intestacy rules, not to whomever you would have chosen. Where there is no surviving spouse or civil partner and no children, the estate goes to relatives in a set order: parents first, then brothers and sisters, then more distant relatives such as grandparents, and aunts and uncles. An unmarried partner or a friend inherits nothing under these rules (gov.uk, rules on who inherits, as at July 2026, subject to change).

Why single people often want a lasting power of attorney

Because there is no spouse to step in if you lose the ability to make decisions. A lasting power of attorney lets you appoint someone you trust to handle either your property and finances, or your health and welfare, if illness or an accident means you cannot. Without one, no family member has automatic authority, and someone may have to apply to the Court of Protection to be appointed instead (gov.uk, lasting power of attorney, as at July 2026, subject to change).

There are two types, and many people put both in place. Being single does not mean you must appoint a relative; you can choose a trusted friend, more than one attorney, or a professional. Applying for a deputyship after capacity is lost is generally slower and more involved than making an LPA in advance, so it is one option some consider while they are well.

• Property and financial affairs. Lets an attorney manage bank accounts, bills and property, once registered.
• Health and welfare. Covers care, medical treatment and where you live, and can only be used once you lack capacity.
• No LPA. Family may have to apply to the Court of Protection to act, which can take longer (gov.uk, as at July 2026, subject to change).

Inheritance tax when you are single

The tax-free bands are the same, but two advantages available to couples are not. A single person has the ordinary nil-rate band of £325,000, and tax is charged at 40% on value above the available bands, or a reduced 36% where at least 10% of the net estate passes to charity (gov.uk, as at July 2026, subject to change). What a single person cannot do is transfer unused allowances to a spouse, because there is no spouse exemption to draw on.

The residence nil-rate band of up to £175,000 can still apply, but only where a home passes to children or grandchildren, taking a threshold up to £500,000; it is not available where a home is left to a partner, friend or sibling (gov.uk, passing on a home, as at July 2026, subject to change). Where the estate is worth more than £2,000,000, that extra band tapers away (gov.uk, as at July 2026, subject to change). These bands are frozen until the end of the 2030-31 tax year (5 April 2031) (gov.uk, as at July 2026, subject to change).

Leaving 10% or more of the net estate to charity is one option some single people consider, which can also reduce the rate on the rest; it can be worth discussing with a qualified professional first.

Single people in Scotland and Northern Ireland

Inheritance tax is a UK-wide tax, so the £325,000 nil-rate band, the residence nil-rate band and the 40% rate apply across Scotland, England, Wales and Northern Ireland alike (gov.uk, as at July 2026, subject to change). The rules on wills and intestacy differ. Scotland has its own succession law, including legal rights that can give certain relatives a fixed share, and Northern Ireland has its own intestacy rules. Where you live in, or hold assets in, more than one UK nation, it can be worth taking advice locally. For the wider picture, see our estate planning guide.
