What is joint tenancy vs tenants in common?
When buying a property with someone else, one of the most important decisions you’ll make is how to legally own it together. The choice between joint tenancy vs tenants in common affects what happens to your share if you die, what happens if the relationship breaks down, and how the proceeds of a future sale are divided.
This guide explains both options in plain English so you can make an informed decision — whether you’re buying with a partner, a friend, a family member, or a business associate.
What is joint tenancy?
Joint tenancy is a form of shared ownership where two or more people own a property together as a single, unified entity. Each owner has equal rights to the whole property — there are no individual shares or percentages. It does not matter if one person paid a larger deposit or contributes more to the mortgage; legally, all joint tenants own the property equally.
The most significant feature of joint tenancy is the right of survivorship. This means that when one owner dies, their interest in the property automatically passes to the surviving owner — regardless of what their will says, and without needing to go through probate.
For married couples or civil partners buying together, joint tenancy is a common and often sensible default. It provides automatic protection for the surviving partner, is straightforward to administer, and avoids the need for specific provisions in a will relating to the property.
What joint tenancy means in practice
- You own the whole property together — not a specific “share”
- All owners must agree before the property can be sold
- If one owner dies, the property passes automatically to the survivor
- You cannot leave your interest in the property to someone else in your will
- Proceeds from a sale are always split equally
What is tenants in common?
Tenancy in common is a form of shared ownership where each person holds a distinct, separate share of the property. Those shares can be equal — such as 50/50 — or unequal, for example 70/30 or 60/40. This arrangement is particularly useful when buyers are contributing different amounts to the deposit or purchase price.
Unlike joint tenancy, there is no right of survivorship in tenants in common. When one owner dies, their share does not automatically pass to the other owner. Instead, it passes according to their will — or, if they do not have a will, according to the intestacy rules. This means the surviving owner may find that they now co-own the property with the deceased’s family members, children from a previous relationship, or even a stranger.
Tenants in common gives each owner much more flexibility and control over their individual share. Each person can — in principle — sell or mortgage their own share independently, and can choose who inherits it. However, this flexibility also introduces complexity, which is why having a declaration of trust is strongly recommended.
What tenants in common means in practice
- Each owner holds a defined share, which can be equal or unequal
- You can specify who inherits your share through your will
- No right of survivorship — your share does not automatically pass to the other owner
- A declaration of trust should be drawn up to record the shares and agree how proceeds are split
- Particularly useful when buyers contribute unequal amounts, or have children from previous relationships to consider
The right of survivorship: what it means and why it matters
The right of survivorship is the legal rule that applies automatically to joint tenants. When one owner dies, their interest in the property transfers immediately and in full to the surviving owner — bypassing the will, bypassing probate, and bypassing any claims from family members.
This can be enormously valuable for couples. If one partner dies unexpectedly, the other retains full ownership and control of the family home without any legal uncertainty. For unmarried couples in particular, this is significant — because without the right of survivorship, there is a real risk that the deceased’s share could end up in the hands of their family rather than their partner.
However, the right of survivorship is also a limitation. If you own as joint tenants and want your share to pass to your children from a previous relationship, or to a sibling, or to anyone other than your co-owner — you cannot do that within a joint tenancy. This is often the main reason couples or co-buyers choose tenants in common instead.
Consider this example: two people own a property together as joint tenants. One dies and their share automatically passes to the survivor. The survivor then remarries and eventually leaves the entire property to their new spouse. The original deceased’s children receive nothing. Had the property been held as tenants in common, the deceased could have directed their share to their own children in their will.
Declaration of trust: what it is and when you need one
A declaration of trust (sometimes called a deed of trust or trust deed) is a legally binding document that records the ownership arrangement between co-owners. It sets out each person’s share, how the property was funded, and what should happen in various circumstances — such as one person wanting to sell, or the relationship breaking down.
If you are buying as tenants in common, a declaration of trust is not legally required — but it is strongly recommended. Without one, the law assumes ownership is split 50/50, regardless of who paid what. If one person contributed 70% of the deposit and there is no deed in place, they may struggle to prove their greater financial contribution if a dispute arises later.
A well-drafted declaration of trust should cover:
- The percentage share each owner holds
- What each person contributed to the deposit and purchase price
- How ongoing mortgage payments and costs are allocated
- What happens if one person wants to sell but the other does not
- How sale proceeds are distributed when the property is eventually sold
For joint tenants, a declaration of trust is less commonly used — since there are no separate shares to record — but it can still be useful to document financial arrangements between co-owners.
Joint tenancy decisions are made as part of the wider conveyancing process, and your solicitor will guide you through the right option for your situation before you register the property.

Which is right for you: joint tenancy or tenants in common?
There is no single correct answer to the question of joint tenancy vs tenants in common. The right choice depends on your circumstances, your relationship with your co-owner, your financial contributions, and your plans for the future.
Joint tenancy may be the better choice if:
- You are married or in a civil partnership and want ownership to pass automatically to your partner
- You both have equal financial contributions and want a simple, unified ownership structure
- You want to avoid the need for specific property provisions in your will
- You are buying in a committed relationship and want equal security for both of you
Tenants in common may be the better choice if:
- You and your co-owner are contributing different amounts and want ownership to reflect that
- You have children from a previous relationship and want to protect their inheritance
- You are buying with a friend, sibling, or business associate rather than a romantic partner
- You want the freedom to leave your share to whoever you choose in your will
- You are concerned about care home fees — tenants in common can help protect part of the property from local authority assessment
What happens if you want to change ownership type?
It is possible to change from joint tenancy to tenants in common — or from tenants in common to joint tenancy — after you have already registered the property. This is done through a legal process called severance of joint tenancy (to convert from joint to tenants in common) or by executing a new deed of trust (to convert from tenants in common to joint).
Circumstances that often prompt a change include:
- Separation or divorce — where one partner wants to be able to leave their share to someone other than their ex
- Marriage or entering a civil partnership — where a couple want to switch to joint tenancy for automatic survivorship
- Change in financial circumstances — where one person has contributed significantly more over time
- Estate planning — where a couple want to protect their respective shares for inheritance tax or care cost purposes
You can notify HM Land Registry directly of a change in ownership type by submitting a form — this is free to do. However, if you want to record the specific shares held and set out the terms of the arrangement, a solicitor should prepare the formal documentation. The GOV.UK guidance on joint property ownership sets out the forms and process involved if you wish to manage this yourself.
Inheritance tax considerations
Both forms of joint ownership can have inheritance tax implications, though the detail depends on the relationship between the owners and who inherits.
When one joint tenant or tenant in common dies and the property passes to their spouse or civil partner, no inheritance tax is due on that transfer — regardless of the ownership type. The spousal exemption applies in both cases.
Where the property passes to someone other than a spouse or civil partner, the value of the deceased’s share is added to the total estate for inheritance tax purposes. This is the same whether you hold as joint tenants or tenants in common — the difference is in who receives the share, not whether tax is due. Careful estate planning, including making a will, is important for anyone co-owning property outside of a marriage or civil partnership.
Summary
The choice between joint tenancy vs tenants in common is one of the most consequential decisions you will make when buying a property with someone else. It determines what happens when one of you dies, what happens if you separate, and how any future sale proceeds are divided.
Joint tenancy is simple, equal, and provides automatic protection for the surviving owner through the right of survivorship. Tenants in common offers more flexibility — particularly around inheritance — but requires more careful planning, ideally including a declaration of trust and an up-to-date will.
