Joint Tenants or Tenants in Common, and Why Almost Nobody Knows Which They Are

When two or more people own a property together, the law offers two ways to hold it. They sound almost interchangeable, which is part of the problem, but they behave very differently when one of the owners dies.

The two options are joint tenants and tenants in common. Every co-owned property in England and Wales is held one way or the other. There is no third option and no in-between.

Most people signed the paperwork years ago, often when buying their first home together, and have not thought about it since. Ask a room full of homeowners which type they are and most will not be able to tell you. Ask them to guess and a good number will guess wrong. Given how much rides on the answer, that is worth fixing.

Hold a property as joint tenants and you and your co-owner own the whole of it together, as one single unit. Neither of you has a distinct share you could point at and call yours. You both own all of it, jointly.

Death is where the defining feature shows up. It is called the right of survivorship. When one joint tenant dies, their interest simply passes to the surviving owner automatically. It happens outside the Will entirely. Whatever the deceased's Will might say about the property, none of it counts, because survivorship comes first and the survivor is left owning the lot.

Plenty of couples want precisely that. You own your home together, one of you dies, and the other owns it outright with no fuss at all. That is the appeal. For a straightforward couple with shared children it often works perfectly well.

The catch is that survivorship overrides your Will. You cannot leave your share of a joint tenancy to anyone else, because you do not have a separate share to leave. This becomes a real problem in situations where you want your part of the home to go somewhere other than straight to the co-owner, which we will come to.

Tenants in common is different. Here each owner holds a defined share of the property. Maybe it is a straight fifty-fifty. Maybe it mirrors who put in what, seventy-thirty, sixty-forty, whatever the two of you agreed.

And this is the part that changes everything: there is no survivorship. Die as a tenant in common and your share does not slide across to the other owner on its own. It becomes part of your estate and passes under your Will, or, if you left none, under the intestacy rules.

This means you keep control of your share. You can leave it to your children, into a trust, or to whoever you choose. The co-owner does not automatically scoop it up. That control is exactly why tenants in common is the structure used for so much protective planning.

The trade-off is that it does not tidy itself away on death the way a joint tenancy does. Your share has to be dealt with through your Will, so having a Will in place matters much more when you own as tenants in common.

The choice between the two shapes what your Will and any trust can actually achieve.

Take an unmarried couple who own as joint tenants. They both make Wills leaving everything to their children. When one dies, the house passes to the survivor by survivorship regardless of what the Will says. The Will's instructions about the house never take effect, because survivorship got there first. If that is not what they intended, they have a problem they do not know about.

Now take a couple in a second marriage, each with children from before, who want their own half of the home to end up with their own children. If they own as joint tenants, they cannot do it, the survivor takes the whole house. To protect each side's children, they need to own as tenants in common, so each half can be left the way they want, often into a trust that lets the survivor stay in the home for life before the share passes on.

This is the single most common reason people get their estate plan wrong without realising. They write a careful Will, or set up a protective trust, and it quietly fails because the property is held as joint tenants and survivorship overrides the lot. The ownership type has to match the plan.

You do not have to guess, and you should not. The answer is on the official title register at HM Land Registry.

You can buy a copy of the register of title for your property from the Land Registry for a small fee. When you look at it, you are checking for one specific thing: a Form A restriction. It usually reads along the lines of no disposition by a sole proprietor of the registered estate under which capital money arises is to be registered unless authorised by an order of the court.

If that Form A restriction is present, you own as tenants in common. If it is absent, you own as joint tenants. That is the reliable test. Not your memory of what you signed years ago, not a guess, but what the register actually says.

If you are not sure how to read the register, that is fine, it is not written for a general audience. The presence or absence of that restriction is the thing to look for, and once you know it you know for certain which type you are.

The useful thing is that you are not stuck with whatever you have. You can change a joint tenancy into a tenancy in common, and this is often exactly what someone needs to do to make a protective plan work.

The process is called severance. Either owner can sever a joint tenancy unilaterally, meaning you do not need the other owner's agreement to do it. You do it by giving written notice of severance to the other owner, under section 36(2) of the Law of Property Act 1925. Once that is done, the joint tenancy becomes a tenancy in common, usually in equal shares, and survivorship no longer applies.

After severing, most people also register a Form A restriction at the Land Registry so the change is recorded on the title. From that point on, each owner has a distinct share they can leave through their Will or into a trust.

Severance is a well-established step, but it needs to be done properly, with valid written notice and the register updated, or the protection you are relying on may not hold. It is the sort of thing worth getting right rather than improvising.

If you own a property with someone else, the sensible first move is simply to find out which type you are. Check the title register for that Form A restriction. Once you know, you can see whether your current ownership matches what you actually want to happen when one of you dies.

For a straightforward couple with shared children who are happy for the survivor to own the whole home, a joint tenancy usually does the job. For anyone who wants their share to go a particular way, into a trust, to children from an earlier relationship, protected against sideways disinheritance, tenants in common is normally the structure that allows it.

Line up the ownership type with the Will and the plan holds. Leave them out of step and it quietly fails. If you cannot see how joint tenancy, tenancy in common, and a trust in your Will fit together for your own situation, our team is on 0800 055 4321 to talk it through.
