Your Will Can't Give Away a House Held as Joint Tenants

If the house is held as joint tenants, she will not get it. Not because the will was badly drafted, and not because anyone contested it — but because your share never reaches the will in the first place. A will only disposes of what you own at the moment of death, and under a joint tenancy your interest in the property passes to the other owner automatically, in the instant you die. There is nothing left for the will to give away.

This is the answer to the question people usually phrase as "does a will override a joint tenancy". It does not. Survivorship goes first, every time, however clearly the will is worded and however recently it was signed. Solicitors see the consequence of this regularly: a parent who genuinely believed they had left their half of the family home to their children, and a child who discovers after the funeral that they have inherited nothing at all.

The fix is a single, specific step called severing the joint tenancy. It is not difficult and it does not need the other owner's permission. But it has to actually be done, and the sentence in the will is not it.

Why the will never gets to your half

The two ways of co-owning a home in England and Wales look identical from the outside. Same front door, same names on the paperwork, same mortgage. The difference is entirely in how the ownership is held, and it only shows itself when somebody dies.

Joint tenants own the property as a single, undivided whole. Legally, there are no halves. Neither owner has a share to point at, sell separately or leave to anyone, because the interest is held jointly rather than in identifiable portions. When one joint tenant dies, their interest does not pass anywhere — it ceases to exist, and the survivor is left owning the whole thing. Lawyers call this the right of survivorship, and it happens by operation of law, immediately, without probate and without any document being signed.

Tenants in common is the opposite arrangement. Each owner has a defined share — often half each, sometimes unequal to reflect who put in what — and that share is an asset like any other. It belongs to the estate on death and it passes under the will, or under the intestacy rules if there is no will.

So the sequence matters more than the wording. A will operates on your estate. Under a joint tenancy your interest in the house is gone before the estate is worked out at all. Nothing is being overridden; the gift is simply pointed at something that no longer exists. If you are not sure which arrangement applies to you, start with our explainer on whether you are joint tenants or tenants in common, because everything else follows from that one fact.

One thing survivorship does not avoid

Because survivorship works without probate, people assume it takes the house out of the picture entirely. It does not, and this is a trap worth naming.

For inheritance tax, the value of the deceased's beneficial share in a jointly owned home still forms part of their estate and is still assessed, even though the property itself never went through the estate administratively. Survivorship avoids the process, not the tax. Transfers between spouses and civil partners are exempt, which is why couples in that position rarely feel this, but it lands differently where the co-owner is a sibling, a friend, an unmarried partner or an adult child.

It has a second consequence too. Because the transfer happens automatically, a family can be told there is "no probate needed" and conclude that nothing else needs doing. Mortgage payments, buildings insurance and the estate's own paperwork all continue regardless. If a property is standing empty while the rest of an estate is dealt with, check whether the buildings insurance is still valid on an empty probate house, because most policies restrict cover once a property has been unoccupied for a set period.

How to find out which one you actually are

Do not rely on memory, on what the estate agent said, or on the will. The register is what decides it, and you can check it yourself for a small fee.

For property in England and Wales, buy a copy of the title register from HM Land Registry using its search property information service. Look in the proprietorship register for a restriction in what is called Form A, which begins "No disposition by a sole proprietor of the registered estate". Its presence means the beneficial ownership is held as tenants in common, so each owner has a share to leave. Its absence, where two people are registered as owners, usually means a joint tenancy — and therefore survivorship.

That is the practical test, and it is the one a conveyancer applies. The government's own summary of the two arrangements is set out on the joint property ownership pages on GOV.UK, including how to change from one to the other.

One nuance worth understanding. The legal title to a co-owned home is always held as a joint tenancy — the law does not permit the legal estate to be split into shares. What can be split is the beneficial interest sitting behind it, which is where the real value lives. So when people talk about severing a joint tenancy, they mean severing the beneficial joint tenancy. The names on the legal title do not change, which is precisely why the register needs a restriction on it to show what has happened underneath.

Severing the joint tenancy: the step that changes the outcome

Severance converts a joint tenancy into a tenancy in common. From that moment you own a defined share, that share belongs to your estate on death, and your will can dispose of it. This is the step that makes the gift to your daughter work.

In England and Wales the usual route is written notice. Section 36(2) of the Law of Property Act 1925 allows one joint tenant to sever by giving notice in writing to the others. Three points about that matter in practice:

• It is unilateral. The other owner does not have to agree, does not have to sign anything, and cannot refuse. They do have to be given the notice properly, and the Act sets out how service works, which is why the notice is usually sent by recorded delivery with the receipt kept.
• It should be registered. After serving notice you apply to HM Land Registry to enter a Form A restriction on the title. Severance is effective between the owners without it, but the restriction is what stops a surviving sole owner later dealing with the property as though the whole beneficial interest were theirs. Without it, your daughter may hold a right that is genuine and extremely difficult to enforce.
• It usually creates equal shares. Severance of a two-person joint tenancy generally produces a tenancy in common in equal shares, regardless of who contributed what to the purchase, unless there is a separate declaration of trust recording something different. If the contributions were uneven, that declaration needs drafting at the same time, not later.

Severance can also happen by mutual agreement, or by a course of dealing that shows both owners treated the property as held in shares. It happens automatically if a joint tenant is made bankrupt, or if one of them disposes of their interest. It does not happen automatically on separation or divorce, which catches a great many people: a couple can be years apart, with the house sitting in a joint tenancy, and the first one to die still hands the whole property to the other.

Once severed, tell whoever wrote your will. A gift of "my share of the property" that was drafted while you were a joint tenant may need rewording now that a share genuinely exists, and executors should be able to find the evidence of severance without hunting for it. If you are doing this alongside other first-time arrangements, our piece on making a will at 27 with a toddler and a joint mortgage covers what else tends to be missed at the same time.

What severance does not change: the mortgage

This is the part that turns a tidy plan into a difficult one, and it is almost never explained at the point the notice is signed.

Severing a joint tenancy alters who owns the house. It does nothing whatsoever to the loan secured on it. Joint borrowers remain jointly and severally liable, which means each of them is responsible for the entire outstanding balance, not half of it. Your death does not reduce the debt and does not split it.

Put the two facts together and the shape of the problem appears. If you sever, and leave your share to your daughter, your surviving partner is left owning half a house alongside your daughter — while remaining liable for one hundred per cent of the mortgage on it. They are paying the whole loan on an asset they now only partly own. That is a stable arrangement while everyone gets on. It is a corrosive one when they do not.

Lender consent is not needed to sever, because you are not changing the security or the borrowers. But the lender's position is unaffected by anything you have done, and any other charge on the property survives too. Where a business has borrowed against the house, this compounds quickly — see what happens to a business loan secured on the family home. The same principle governs rental property held jointly, with an added deadline, because buy-to-let mortgages are usually repayable on death rather than simply continuing.

The trade-off nobody explains before you sign

Severance solves one problem by creating another, and it is better to choose that knowingly.

Before severance, your partner is safe and your daughter gets nothing. After severance, your daughter is protected and your partner's home is no longer wholly theirs. A share owned by someone else is a share that person can eventually ask to realise. Where co-owners cannot agree what to do with a property, either of them can apply to the court for an order about it under the trusts of land legislation, and the court has power to order a sale. That is a real risk, not a theoretical one, particularly where the daughter is from an earlier relationship and needs the money for her own life.

There are middle paths. A share can be left on trust so that your partner has the right to live in the house for their lifetime, with the value passing to your daughter afterwards — that keeps a roof over one person without disinheriting the other, at the cost of some complexity and a trustee to appoint. Severance can also be reversed later by agreement if circumstances change.

The cleanest answer, where it is affordable, is usually to stop making the house do two jobs. Leave the property to your partner by survivorship, so they keep their home and their security, and provide for your daughter with money instead. Level term cover pays a fixed sum on death, and it can be written so that the money goes to a named person quickly, without waiting for the estate to be administered. That is what turns "she gets half a house she cannot sell" into "she gets what you actually intended to give her", and it leaves the mortgage question untouched because nobody is being asked to buy anyone out. What an insurer will offer depends on age, health and underwriting, so it is worth having the figures priced rather than assumed — you can get life insurance quotes and have an FCA-authorised broker set the sum against what your share is actually worth.

Two further points of honesty. First, severing does not put your estate beyond challenge: a surviving spouse, civil partner, cohabitant or dependant may still be able to apply for reasonable financial provision from it, so cutting a partner out of the house does not guarantee the outcome you wrote down. Second, the word "succession" means something entirely different in a rented home, where surviving a joint tenancy uses up the one succession the family gets — a trap for tenants rather than owners, but one that has caused the same shock in a different setting.

Scotland and Northern Ireland

None of the English machinery above is read across, and the differences are substantial rather than cosmetic.

Scotland has no joint tenancy or tenancy in common. Co-owners hold separate shares in the title, known as pro indiviso shares, and those shares normally pass under the will. Survivorship only arises where the title deed contains a special destination — a survivorship clause naming the co-owner. Where one exists, it is powerful: a later will does not evacuate a special destination unless it refers to that destination specifically and says clearly that it is being defeated, and in some cases the destination cannot be evacuated at all. If you own in Scotland and intend to leave your share to a child, the deed itself has to be checked, not just the will. Children's legal rights in Scotland attach to moveable estate rather than to the house.

Northern Ireland recognises joint tenancy and survivorship, but the Law of Property Act 1925 does not apply there, so the tidy statutory notice route above is not simply available in the same form, and land is registered through separate Northern Ireland systems. Take local advice from a solicitor before serving any notice. Cohabiting couples in particular should read what claim a cohabitant can make on the house in Northern Ireland, because the position for unmarried partners differs from England and Wales.

Frequently asked questions

Does a will override a joint tenancy?

No. Where a property is held as joint tenants, your share passes automatically to the other owner on your death by survivorship, before the will takes effect at all. A gift of that property in your will simply fails, however clearly it has been worded. The will is not being overridden — there is nothing left in the estate for it to operate on.

How do I make sure my children get my share of the house?

You sever the joint tenancy, so the property is held as tenants in common and you own a defined share that can be left by will. Severance is done by written notice to the other owner, with a Form A restriction then entered on the title register at HM Land Registry. Update the will at the same time so that the gift matches what you now own.

Can I sever a joint tenancy without my partner agreeing?

Yes. In England and Wales severance is a unilateral act: you serve written notice on the other joint owner and apply to HM Land Registry for a Form A restriction. Their consent is not required, although the notice must be given to them properly, which is why it is usually sent by recorded delivery and the proof kept. The position in Scotland and Northern Ireland is different, so take local advice there.
