Scope: England. Wales uses occupation contracts with a genuinely easier mechanism for adding and removing contract-holders — see below. Verified against the Renters’ Rights Act 2025 (c.26) on 10 August 2026.
A joint tenancy is one tenancy held by several people, not several tenancies stacked. Almost every operational surprise follows from that.
Joint and several liability
Each joint tenant is liable for the whole rent, not a share. One stops paying and you may pursue any of the others for the full amount — the model’s real commercial advantage, and the reason it survives.
It cuts the other way too: a tenant who moves out remains liable while the tenancy continues, whatever they agreed among themselves. Their private arrangement does not bind you.
The rule that now matters much more
Notice to quit by one joint tenant ends a periodic tenancy for all of them. Long-standing law, and it used to be a curiosity because most tenancies sat inside a fixed term where it did not arise.
Fixed terms are gone in England. Every new tenancy is periodic from the start, so every joint tenancy is now permanently in the state where one tenant can end it for everyone.
Consequences worth planning for:
- One tenant falls out with the others, serves notice, and the remaining tenants’ right to occupy ends with it.
- You may be content to re-let to the remainder — but that is a new tenancy, with a new deposit, new prescribed information and new compliance documents.
- A tenant can use it as leverage. There is no cure for that in the tenancy; there is only knowing it is the position.
Changing one tenant, properly
"Swapping a name" is not a thing. Two lawful routes:
Surrender and re-grant
End the existing tenancy by agreement and grant a new one to the new line-up. Clean, and the usual choice. It is genuinely new, so:
- the deposit must be returned and re-protected, or the protection formally reassigned, with fresh prescribed information;
- all compliance documents are served again;
- any rent increase happens here, not by variation.
Deed of assignment
The outgoing tenant assigns their interest to the incoming one, with the landlord’s consent and all parties signing. The tenancy continues, so the deposit protection and documents ride on — but the deed must be right, and a badly drafted one can operate as a surrender by accident.
Deposits, precisely
One joint tenancy means one deposit, protected once, with prescribed information served on each tenant. Points people miss:
- On a surrender and re-grant you are protecting afresh — the 30-day clock restarts.
- Repaying an outgoing tenant’s "share" from the protected deposit is not straightforward. The deposit relates to the tenancy, not to individuals; the usual answer is for the incoming tenant to pay the outgoing one directly, outside the scheme.
- Getting protection wrong on the re-grant exposes you to the one-to-three-times penalty all over again.
Possession is against all of them
You cannot evict one joint tenant. Possession under any Section 8 ground is against the tenancy, so notice is served on all and the order removes all. Where one tenant is the problem, individual room tenancies would have been the right structure — see joint vs individual tenancies.
Guarantors
A guarantor for a joint tenant has usually guaranteed the whole rent, not their tenant’s share. Whether that survives a change of tenant depends on the wording — a surrender and re-grant generally ends the guarantee, because the tenancy it guaranteed no longer exists. See guarantors.
Wales
Occupation contracts allow joint contract-holders to be added and removed without ending the contract, which is materially easier than the English surrender-and-re-grant dance. A departing contract-holder can withdraw, and the contract continues for the rest. Each contract-holder needs a written statement.
