Joint tenancy agreements: liability, leavers and name changes
Most shared rentals – couples, friends, house shares – sit on a joint tenancy: one agreement, several named tenants. It works invisibly until somebody wants to leave, and then it becomes the most misunderstood corner of renting. Here is how joint tenancies actually operate under the 2026 rules. (Searching about jointly owning a property – joint tenants vs tenants in common? That is a different legal concept entirely; this page is about renting.)
Joint and several liability: the core deal
Every joint tenant is liable for the whole rent and every obligation – not their "share". If one housemate stops paying, the landlord can pursue any or all of the others for the full amount. This is the clause that makes shared lets viable for landlords, and the one tenants most often discover the hard way.
When one joint tenant wants to leave
The uncomfortable rule: a valid notice from one joint tenant – two months, ending on the last day of a rent period – ends the tenancy for everyone. The remaining tenants have no automatic right to stay on the old agreement. In practice the parties usually do one of two things:
- Sign a fresh agreement with the remaining (or replacement) tenants – the clean solution, and the moment to update rent, deposit and terms.
- Agree a deed of assignment swapping one tenant for another on the existing tenancy – less common, and needs everyone's consent including the landlord's.
Removing or adding a name
There is no form for "just taking a name off". A name change means either a new agreement or an assignment, and the deposit needs attention at the same time: the outgoing tenant's stake is usually repaid or transferred, and the protection scheme updated. Relationship breakdowns follow the same mechanics – with the added wrinkle that either party can end the whole tenancy unilaterally, so getting a new agreement in place early protects whoever is staying.

Can one person leave a joint tenancy?
Yes – but their valid notice ends the tenancy for all joint tenants, not just themselves. The remaining tenants should agree a new tenancy with the landlord if they want to stay.
Is each joint tenant only liable for their share of rent?
No. Joint and several liability means each tenant can be pursued for all of the rent and any damage, regardless of private arrangements between the sharers.
