Joint Tenants vs Tenants in Common: The Question Every UK Couple Should Ask

A plain-English guide to the two ways of owning property together in the UK, and why the tick box at the bottom of the form matters more than it looks.

Young professionals SEND families New to the UK Trusts & wills

Wait, there's more than one way to own a house together?

Yes. And most people find out about it after they have already signed.

When two or more people buy a property in England or Wales, the solicitor asks a single question, usually near the bottom of a long form: "Do you want to hold as joint tenants or tenants in common?" In most cases, someone ticks a box, no one explains what it means, and everyone moves on to the boxes and the kettle.

Then, years later, a death, a divorce, a fallout, a second marriage, and that tick becomes the most important decision in the paperwork.

Okay, so what is a joint tenant?

Joint tenants own the whole property together, as one legal unit. Nobody owns a "share." You both own 100%, at the same time.

The critical bit is what happens when one of you dies: the property passes automatically to the survivor. It does not go through your will.

For many married couples or civil partners buying their first home together, this is exactly what they want. Simple, automatic, one less thing to worry about.

And tenants in common?

Tenants in common each own a defined share. 50/50, 70/30, 90/10, whatever you agree. Your share is yours. You can leave it to whoever you want in your will. It does not automatically pass to the other owner.

Same house, same mortgage, same front door, a very different legal machinery underneath.

Why would anyone choose tenants in common?

Because life is often more complicated than the standard form assumes. Some situations where people commonly land here:

Unequal contributions. One person puts in a £100k deposit, the other £20k. Under joint tenants, if things end in year two, the equity is legally 50/50 regardless of who paid what.
Children from a previous relationship. Under joint tenants, when the first person dies their share goes to their partner, not their children. The surviving partner is then free to leave the whole house to anyone. Children from a previous relationship can end up with nothing. This is called sideways disinheritance.
Buying with a friend, sibling, or business partner. Defined shares almost always make more sense here.
Wanting a share to go into a trust on death, whether for a disabled child, for tax planning, or for anything else. Joint tenants blocks that entirely, because the share passes to the co-owner before the will activates.
Care fees planning. Tenants in common with a share in trust is one of the (limited, imperfect) tools people look at here. Joint tenants shuts that door.

What is a declaration of trust?

A short legal document that sits alongside the deeds and records the bit the deeds do not: who paid what, who owns what percentage, and what happens if things change. It is relatively cheap to set up at the point of purchase (typically £300 to £800) and enormously expensive to sort out after a dispute.

For tenants in common with unequal shares, it is very common to have one. Even for joint tenants where one person paid substantially more of the deposit, some people choose to have that conversation before signing rather than after.

Do all conveyancing solicitors even ask?

Not consistently, from what I have seen and heard.

Some solicitors ask directly and talk you through the difference. Others default you to joint tenants and mention it only in passing, or you notice it only when you are signing the TR1 transfer form. A few will proactively flag it if they can see the situation is more layered (unequal deposits, blended families, business partners).

So the honest picture is: sometimes the conversation happens for you, sometimes it does not. If it matters to you, it is worth being the one to raise it, ideally before exchange.

Ways people check where they stand:

Dig out the TR1 form or Land Registry title from purchase.
Download the title register from gov.uk/search-property-information for £3.
Ask the solicitor directly, in writing, which arrangement is being set up and why.

We already bought as joint tenants. Are we stuck?

No, and this is the bit almost no one knows. A joint tenancy can be severed at any time, without needing the co-owner's agreement. It is a written notice to HM Land Registry, one form, no fee (if done by yourself).

Once severed, the owners become tenants in common in equal shares (50/50) by default, unless a different split is recorded.

Does this affect our mortgage?

No. The lender does not care whether you are joint tenants or tenants in common, they care that the mortgage gets paid. Both borrowers remain jointly and severally liable for the full mortgage either way. If one stops paying, the bank goes after the other, whether they own 50% or 5%.

Worth sitting with for a second. Owning less of a house does not mean you owe less of a mortgage.

What about inheritance tax?

Different mechanics, sometimes different outcomes.

Joint tenants: the property passes to the survivor automatically. Between spouses or civil partners, that is generally covered by the spouse exemption. Between unmarried partners or friends, it forms part of the estate and can be relevant for inheritance tax.

Tenants in common: the share passes via the will. Between spouses or civil partners, still generally covered by the spouse exemption. But there is now the option to leave a share to children, into a trust, or across several people, which for larger estates can matter a lot for planning.

For estates comfortably below the £325k nil-rate band (plus the residence nil-rate band where applicable), this is largely academic. For estates near or above the thresholds, it can be the whole conversation, and one worth having with a solicitor or tax adviser.

And if we are not married or in a civil partnership?

This is the bit that quietly worries a lot of people once they realise it.

There is no such thing as common-law marriage in England and Wales. It does not exist. For unmarried couples living together, when one person dies:

Joint tenants: the house passes to the survivor.
Tenants in common with a will leaving the share to the partner: the house passes as intended.
Tenants in common with no will, or joint tenancy severed with no will: the share follows the intestacy rules, which go to blood family, not the partner. A surviving partner can end up in a genuinely difficult position, including losing the home.

If you are unmarried and buying together, it is worth deciding on purpose rather than drifting.

What can I actually do this week?

A few practical things people find useful:

Find the TR1 form or Land Registry title from the purchase. It will show which arrangement is in place.
If you cannot find it, download the title register for £3 at gov.uk/search-property-information.
Ask yourself: if I died tomorrow, does the house end up where I want it to end up? If the answer is "I am not sure" or "no," that is worth exploring.
Look at the will alongside the ownership. Ownership structure and the will are two halves of the same conversation. One without the other is half a plan. This is also a good moment to think about a Lasting Power of Attorney.

The kinds of questions I help people ask themselves

This is exactly the sort of quietly important topic that gets pushed to "one day" because it feels legal and dry, and then matters enormously when life changes.

I do not give legal or financial advice. What I do is help people surface the questions that are worth asking: How are we actually set up? Does that still match the family we have? What do we want to happen if one of us dies? Who is the right professional to take this to next?

If you are buying together, remarrying, blending families, or looking again at a tick box made ten years ago, a free discovery call is a good place to start. Plain English, no jargon, no upsell.
