When two or more people decide to buy a house or piece of land together — whether a couple, friends, family, or business partners — it’s important to pick the right way to own that property. In the UK, co-owners normally choose between two main options: Joint Tenants or Tenants in Common.
How you choose will govern what happens if someone dies, if one person wants to sell, or if you want unequal ownership shares.
Here’s how it works — in everyday terms.
Joint Tenants vs Tenants in Common — What’s the Difference?
Joint Tenants
- Everyone owns the whole property together. No one owns a “slice” — you’re all co-owners of the entire property.
- You share equal rights: all co-owners have equal access, and decisions (like selling or remortgaging) must be agreed by all.
- Most importantly: when one co-owner dies, their share automatically passes to the surviving owner(s) — this is called the “right of survivorship.” You can’t leave your share to someone in a will.
- Because of this, joint tenancy is often popular with married couples or long-term partners who want a simple, automatic transfer.
Pros: easy, straightforward, no need to worry about wills or inheritance for the property.
Cons: no flexibility — everyone shares equally whether or not they contributed equally; you can’t leave your share to someone outside the co-owners.
Tenants in Common
- Each co-owner has a defined share or percentage of the property. It could be 50/50 — or 70/30, 60/40, or any ratio you agree.
- Shares don’t need to be equal: good for situations where people contribute different amounts (e.g. deposit, mortgage, improvements).
- When one person dies, their share does not automatically go to the others. Instead, it becomes part of their estate and can be passed via their will — meaning you can leave your share to children, relatives or whoever you choose.
Pros: Flexible, fairer when contributions differ, and allows co-owners to plan inheritance or legacy.
Cons: More complex: you may need a legal “Deed of Trust” to record shares and decisions; if one owner wants to sell their share, this can complicate things for the others.
Why Choosing the Right Ownership Structure Matters
- If one owner dies — under joint tenancy the property goes automatically to the survivor. Under tenants in common, the share can go to children or others via a will.
- If contributions differ — tenancy in common allows this to be recognised; joint tenancy treats everyone equally no matter how much they put in.
- If one owner wants to sell or withdraw — tenants in common allows individual shares to be sold; joint tenants all need to agree to sell.
- For flexibility and future planning — tenants in common offers more control, especially for families, friends, investors, or co-owners who want to leave their share to someone specific.
How to Set Up Co-ownership
- When you buy a property with others, you (or your solicitor) must specify on the official forms how you wish to own it — as joint tenants or tenants in common. The registration with the official registry (HM Land Registry) will record your choice.
- If you don’t specify, a default restriction may be placed — which can lead to legal uncertainty.
- Many people who choose tenants in common also create a Deed (or Declaration) of Trust — a legal document that defines exactly who owns what share, who paid what, and what happens in case of sale, death or separation.
Common Pitfalls & What to Watch Out For
- Assuming equal contribution = equal share — If you’re not married or have different contributions, joint tenancy can be unfair.
- Not thinking about inheritance — Under joint tenancy you can’t leave your share to children or others; it automatically goes to co-owner(s).
- Changing circumstances — Relationships break down, an owner wants to sell or remortgage, someone contributes more later — tenancy in common gives flexibility; joint tenancy may create complications.
- Tax & financial consequences — Especially for non-married co-owners, or where shares are unequal — you might need to consider tax, estate planning, etc.
Frequently Asked Questions – Co-Ownership of Property
-
What are the main ways to co-own a property?
You can own a property as either joint tenants or tenants in common. This affects how ownership is shared, what happens when one owner dies, and how decisions are made.
-
What does being “joint tenants” mean?
Joint tenants own the whole property together equally. If one owner dies, their interest automatically passes to the surviving owner(s), outside of a will.
-
What about “tenants in common”?
Tenants in common each own a defined share, which can be equal or unequal. An owner can leave their share to anyone in a will.
-
How do we record this legally?
You choose the ownership type in the transfer documents submitted to the Land Registry. Many co-owners also create a Deed of Trust to record shares and any special terms.
-
Can we change from joint tenants to tenants in common later?
Yes. This is called severing a joint tenancy. You apply to the Land Registry (often using Form SEV) and register a restriction on the title.
-
Do all co-owners have to agree to the change?
No. In many cases, one co-owner can sever a joint tenancy without the consent of the other owner(s), as long as the correct notice is given.
-
What happens when one co-owner dies?
Joint tenants: the property automatically passes to the surviving owner(s) and cannot be left by will. Tenants in common: the deceased’s share passes under their will, or intestacy rules if there is no will.
-
What if one owner contributed more (deposit, mortgage, renovations)?
If contributions are unequal, tenants in common is usually better. You can set different share percentages or record contributions and rules in a Deed of Trust.
-
Can I sell my share without the others agreeing?
Tenants in common: you can sell your share, although it may be hard in practice. Joint tenants: a sale usually requires all co-owners to agree.
-
Is co-ownership only for married couples?
No. Friends, siblings, business partners, and unmarried couples can all buy together. The key is choosing ownership terms that match your situation.
Final Thoughts — What You Should Do Before Buying Property Together
- Talk openly about contributions, ownership shares, future intentions (inheritance, sale, children).
- Decide carefully whether joint tenancy or tenancy in common fits your situation.
- Use a Deed of Trust if you want to document financial contributions, share proportions, and future plans.
- Consider what happens on death or separation — make sure your wishes are clear (especially if you’re not married).
- Get legal advice before signing — a conveyancer or solicitor can help you avoid common mistakes.
