Can I Leave Everything to One Person?

Unlike some countries, England and Wales has no system of 'forced heirship' that guarantees children or a spouse a fixed share of an estate. You are free to leave specific gifts, cash sums or your entire residuary estate to one chosen person, and to leave other relatives nothing, provided your will is validly made.

This freedom covers most situations parents, partners and friends will ever need. Many people do leave everything to a spouse, a single child, or a close friend, and there is nothing unusual or legally problematic about doing so, provided the will is clearly worded and properly executed.

The principal restriction on testamentary freedom is the Inheritance (Provision for Family and Dependants) Act 1975. It allows certain people, including a spouse or civil partner, a former spouse who has not remarried, a child of the deceased, someone treated as a child of the family, or a person who was financially maintained by the deceased, to apply to court if they believe the will (or intestacy) does not make reasonable financial provision for them.

A successful claim does not automatically overturn your wishes, but a court can redirect part of the estate to the claimant if it agrees reasonable provision was not made. Claims are more likely where a dependant is left with genuinely nothing and had a reasonable expectation of support, so if you are leaving everything to one person and excluding someone who might have grounds to claim, it is worth taking advice and considering a short letter of wishes explaining your reasoning.

If you intend everything to go to one person, this is usually achieved by naming them as the sole beneficiary of your residuary estate, meaning everything left after debts, funeral costs and any specific gifts. It is important that the wording is clear and unambiguous, so there is no room for dispute about your intention.

You should also name a substitute beneficiary in case your chosen person dies before you or at the same time as you. Without one, that share could fall into intestacy and be distributed under the fixed statutory rules rather than to anyone you would have chosen, which usually defeats the whole purpose of the will.

Under section 15 of the Wills Act 1837, if a beneficiary (or their spouse or civil partner) acts as a witness to your will, the gift to them fails, even though the rest of the will remains valid. This matters most when leaving everything to one person, because an innocent mistake, such as asking your intended beneficiary's partner to witness the signing, can accidentally invalidate the very gift you intended to make.

Always use two independent, adult witnesses who have nothing to gain under the will, and make sure they are present at the same time as you sign, following the correct signing procedure so the will is valid.

A straightforward will leaving everything to one person, such as a spouse or an only child, with no unusual family circumstances, is well suited to a clear online will service. If you are deliberately excluding a spouse, a child, or someone who was financially dependent on you, take advice first, since these are exactly the situations where a 1975 Act claim is more likely.

My Posh Will lets you set out your wishes clearly, including who inherits your residuary estate and who steps in if they cannot, through an online guided process. A single will costs £69 and mirror wills for couples cost £89, both one-off payments with lifetime access, and most people complete their will in about ten minutes, with clear instructions for signing and witnessing correctly.
