Joint Tenants or Tenants in Common on Completion Day

Your conveyancer has sent the TR1 transfer form and it will not go to completion until one box is ticked: will you hold the new house as joint tenants or as tenants in common? It is tempting to treat this as legal small print and let the solicitor decide. Do not. This is one of the few decisions on the whole purchase that only you can make, and it settles who gets your share of the home if you die before your co-owner does.

Here is the short version, so you can answer the question today. The difference between joint tenants and tenants in common is what happens to a share on death. Joint tenants own the whole property together as one indivisible thing, and when one owner dies the survivor automatically owns all of it, regardless of what any will says. Tenants in common own separate, defined shares — often half each, but they can be unequal — and each share passes under that owner's will, or under the intestacy rules where there is no will.

Which should you choose when buying? For a married couple putting in roughly equal money and leaving everything to each other, a joint tenancy is the common choice and rarely causes trouble. Where the deposit is unequal, where either of you has children from a previous relationship, or where you are not married, tenants in common with a declaration of trust is usually the safer answer. The rest of this page explains why, and what each option would actually cost the survivor.

What the TR1 form is actually asking you

The TR1 is the deed that transfers the property into your names at HM Land Registry. Where there is more than one buyer, it contains a panel asking how you will hold the property. There are effectively two answers: as joint tenants, or as tenants in common in shares you specify. Your solicitor needs the tick because it determines what wording goes on the register and whether a restriction is added to the title.

The reason the form forces a choice is that the two arrangements deal with death in opposite ways, and the law will not guess. Owning a house together is not one thing; it is two quite different legal relationships that happen to look identical from the outside. You both live there, you both pay the mortgage, your names are both on the deed. What differs is invisible until one of you dies, which is exactly why it is so easily ticked without thought and so painful to discover later.

If you want to understand what the finished register looks like and how to read your own once the purchase completes, the mechanics of how joint tenants and tenants in common are told apart on the title are worth a look. For today, though, the only thing you have to do is choose.

Joint tenants: the whole thing passes to the survivor

Under a joint tenancy, neither of you owns a distinct share. You own the whole property together, and the defining feature is the right of survivorship. When one joint tenant dies, their interest does not form part of their estate at all. It simply falls away, and the survivor is left owning the entire property automatically.

This has real advantages for a straightforward couple. The transfer to the survivor happens outside the will and generally without waiting for a grant of probate, so the survivor is not left in limbo over the roof above their head while the estate is administered. A will that leaves everything to each other cannot be undermined, because survivorship overrides the will entirely — the house never enters the will's reach.

The catch is the flip side of that same feature. Because survivorship overrides the will, a joint tenancy cannot be used to leave your share of the home to anyone else. If you have a child from a previous relationship you would want to inherit your half, a joint tenancy quietly disinherits them: your share goes to your co-owner and, on your co-owner's later death, potentially to their family rather than yours. For first-time buyers with no such complication this is usually fine. For a blended family it can be the wrong answer by default.

Tenants in common: shares that go where your will says

As tenants in common you each own a defined share — commonly half each, but it can be 70/30, 60/40 or any split you record. Crucially, your share is yours to leave. On death it does not pass automatically to your co-owner; it passes under your will, or, if you have not made one, under the intestacy rules.

That flexibility is the whole point, and it is why tenants in common suits unequal contributions, unmarried couples and second families. You can leave your share to your children while giving your partner the right to keep living there, or split it in the proportions that reflect what each of you put in. The trade-off is that nothing happens automatically. The protection you gain depends entirely on your will actually saying what you intend — and on there being a plan for the money, because inheriting a share of a house is not the same as being able to keep it.

There is a trap here that catches unmarried buyers in particular. If you hold as tenants in common and die without a will, your share does not go to your partner — cohabitants inherit nothing under the intestacy rules — but to your blood relatives. Your surviving partner can then find they own their own home alongside your parents or siblings. We set out that specific outcome, and the paperwork that prevents it, in the guide to choosing between joint tenants and tenants in common when you are not married.

Unequal deposits: why tenants in common usually wins

The single most common reason to choose tenants in common at the outset is an unequal deposit. Say one of you contributes far more of the deposit than the other — from savings, an inheritance, or a gift from parents. Under a joint tenancy the law treats you as owning the whole thing equally, and if the relationship ends or one of you dies, that larger contribution can simply vanish into a 50/50 split.

Tenants in common lets you record the truth. You set your shares to reflect what each of you actually put in, and you back it up with a declaration of trust — a short deed, drawn up alongside the purchase, that states the contributions, the shares, and what happens to the proceeds if the house is sold. Years later, memories differ and bank statements are long gone; the declaration of trust is the document that settles it. If you are buying with unequal deposits and your conveyancer has not raised a declaration of trust, ask about one before completion, not after.

Where children's money is involved — for instance where a share is intended to pass into a trust for a child rather than to an adult outright — the question of who would manage that money becomes real, and it is worth reading about whether a solicitor should act as a trustee for your children's money before you name anyone.

What a survivor would need to buy out an inherited half

This is the part the TR1 tick sets in motion but nobody prices at the time. Suppose you choose tenants in common precisely so that your share goes to your children rather than automatically to your partner. That works — but it means your partner may end up co-owning the home with your children, and to keep the house outright they would have to buy that inherited share.

The value of a half share is not half the house price. It is a share of the equity: the market value of the property less whatever is still owed on the mortgage. So a survivor buying out a deceased co-owner's half needs to raise roughly half of that equity in cash, or by remortgaging — on top of remaining liable for the mortgage itself. On a single income, after a bereavement, that is often the hardest money in the world to find. A lender assessing a remortgage into one name looks at that one income alone, and can decline it even though the survivor already lives there and has always paid.

To get a sense of the scale for your own area rather than a national average, HM Land Registry publishes average sale prices down to local authority level, updated monthly. Look up your district, subtract your likely mortgage, and halve what is left: that is the order of sum a survivor would need to keep the home. It is usually a large number, and it is precisely the gap that life cover written for the purpose is meant to fill.

Whichever way you tick the box, then, a survivor can be left needing a substantial sum quickly — either to clear a mortgage they are now solely liable for, or to buy out a half share that has passed to someone else. If you are arranging the mortgage anyway, this is the natural moment to get life insurance quotes priced against your actual balance and the share you are each leaving. It is worth knowing, too, that no lender or law obliges you to buy life cover with a first mortgage — the decision, like the TR1 tick, is genuinely yours.

Protecting a share for children without leaving them stranded

If the reason you are leaning towards tenants in common is to make sure your share reaches your own children, the ownership box is only half the job. The other half is making sure your partner or the children are not forced to sell to realise that share, and that any money reaches the children in a form that is actually usable. A share of a house is not spendable, and a lump sum handed to a young adult, or to a child through a trust, needs someone sensible in charge of it.

Where children are minors, the money cannot be paid to them directly and trustees hold it until they are old enough — the same structure people use when they want to direct life cover to their children rather than to a former partner. And where a child has a disability and relies on means-tested support, paying a share or a policy to them outright can do more harm than good, which is the subject of leaving money to an autistic child without stripping their benefits. The ownership choice and the trust choice are two halves of one plan; deciding the first without the second is how families end up with a house nobody can afford to keep.

This is a choice you can change later

None of this is permanent. If you tick joint tenants today and your circumstances change — a new child, a large gift, a wish to leave your share elsewhere — you can convert to tenants in common at any time by severing the joint tenancy. That is done by giving written notice to the other owner and applying to HM Land Registry, which then enters a Form A restriction on the title to show the property is now held in shares. It does not require the other owner's agreement, and it does not mean moving house.

The reverse is also possible. Tenants in common can move back to a joint tenancy by deed and an application to the registry, if a couple's circumstances simplify and they decide survivorship is what they want after all. So do not treat the TR1 as a decision you are locked into for the life of the mortgage. Treat it as the right answer for where you are now, and revisit it when life changes — a marriage, a divorce, a child, or a large inheritance are all natural prompts, as is marrying later in life when there are children from before.

Scotland and Northern Ireland

The TR1 form and the joint tenants or tenants in common labels are features of the law in England and Wales. The underlying choice — automatic survivorship versus a share that passes under your will — exists across the UK, but the machinery and the terms differ.

In Scotland, property is registered with Registers of Scotland, not HM Land Registry, and co-owners hold in shares by default. What plays the role of survivorship is a survivorship destination written into the title, which passes a deceased owner's share to the survivor independently of the will. Scotland also has forced heirship: a spouse's and children's legal rights can be claimed against a Scottish estate regardless of what the will or the title says, which changes the planning considerably. Northern Ireland recognises both joint tenancy with survivorship and tenancy in common much as England and Wales does, but registration is handled by Land and Property Services and some succession rules differ. Wherever you are buying, the principle to hold on to is the same: the way you take the title decides where your share goes, so make the choice deliberately, and put a will and a plan for the money behind it. Our guide to life events that change who depends on you collects the related decisions in one place.

Frequently asked questions

What is the difference between joint tenants and tenants in common?

Joint tenants own the whole property together, and on a death the survivor automatically owns all of it, whatever a will says. Tenants in common own defined shares, which can be unequal, and each share passes under that owner's will or under the intestacy rules. The practical effect only shows itself when one owner dies, which is why the distinction is so easy to overlook when you are simply ticking a box before completion.

Which should we choose if we put in different deposits?

Tenants in common is the usual answer, with a declaration of trust recording the shares. That protects unequal contributions on a later sale, so a larger deposit is not silently split in half. The trade-off is that a share does not pass automatically to your co-owner, so a will and life cover matter considerably more: without them, a share can go to relatives rather than to the person you live with, and the survivor may have to buy it back.

Can we change our minds later?

Yes. A joint tenancy can be severed at any time by written notice to the other owner, and HM Land Registry then enters a Form A restriction on the title to show it is held in shares. Moving from tenants in common back to a joint tenancy is also possible, by deed and an application to the registry. Neither change requires you to move, and either is a good prompt to review your will at the same time.
