Joint tenancy agreement liability: what landlords need to know in 2026
Letting to a group of sharers usually means one joint tenancy agreement rather than several separate ones. That single agreement creates a kind of liability that catches landlords out once something changes: a tenant falls behind, a sharer wants to move out, or a relationship breaks down. This guide covers joint and several liability, rent splitting between sharers, and what actually happens when one joint tenant wants to leave.
What "joint and several liability" actually means
When two or more people sign a single tenancy agreement, each is liable for the whole rent, not just their own share. This is the default position for any joint tenancy unless the agreement says otherwise. You can pursue any one tenant, or any combination of them, for the full amount owed - it is not a defence for a tenant to say "I only owe my third." If one sharer stops paying or disappears, the others remain on the hook for the entire rent. The same principle applies to the deposit: a joint tenancy has one deposit, protected as a single sum, and a deduction caused by one tenant comes out of that shared pot rather than their contribution alone.
Splitting the rent between sharers
Groups of sharers commonly divide rent between themselves either equally, or on a weighted basis where whoever has the bigger room pays a bit more. Either is common practice. What matters for you as landlord is that this is a private arrangement between the tenants - it has no bearing on the tenancy agreement itself, which simply states one total rent owed jointly by everyone named on it. You are not a party to how they divide it up, and it is worth resisting getting drawn into disputes about who owes whom internally. Your contractual relationship is with the group as a whole, for the whole rent.
When one joint tenant wants to leave mid-tenancy
This is where most confusion happens. You cannot simply strike one name off an existing joint tenancy and carry on - it is a single legal agreement shared by everyone named on it, with no mechanism to edit out one party while leaving the rest untouched. If a sharer wants out but the others want to stay, the realistic options are:
- Surrender and re-grant - the existing tenancy ends by agreement and you grant a fresh tenancy agreement to the remaining tenants plus any replacement. The cleanest route, and the one most landlords use.
- Assignment - if the original agreement allows it, the departing tenant's interest transfers to someone else, usually with your consent required.
- Remaining tenants cover the rent - if nobody replaces the departing sharer, the others stay liable, between them, for the whole rent.
| Option | What it means | Who needs to agree |
|---|---|---|
| Surrender and re-grant | Old agreement ends, new one starts with remaining tenants plus any replacement | Landlord and all existing tenants |
| Assignment | Departing tenant's interest transfers to a new tenant, agreement continues | Usually landlord's consent, per the tenancy terms |
| Remaining tenants cover rent | No replacement found, existing tenants stay jointly liable for the full rent | No agreement needed - liability continues automatically |
Periodic tenancies and the notice-to-quit rule landlords get wrong
Since the Renters' Rights Act abolished fixed terms on 1 May 2026, every tenancy is now an assured periodic tenancy from day one. A tenant ending it under section 20 of the Act must give at least two months' written notice, expiring at the end of a rent period, unless a shorter period has been agreed with the landlord.
The point that trips landlords up: when only one member of a joint tenancy serves that notice, it is a long-standing rule of law, confirmed under the current periodic framework, that a valid notice to quit served by just one joint tenant ends the entire tenancy for every joint tenant - even if the others want to stay and were not consulted. The remaining sharers do not automatically carry on under the old agreement; if they want to stay, you need to grant them a new one, on whatever terms you choose.

Can I just remove one name from a joint tenancy and carry on? Not usually. A joint tenancy is one agreement shared by all named tenants, so dropping one name generally needs a surrender of the old agreement and a new one granted to those staying, plus any replacement - or an assignment if the tenancy allows it.
Do I have to accept a replacement tenant the sharers find themselves? No. Bringing in a new joint tenant means granting a new tenancy, which is your decision. You can reference and credit-check a proposed replacement just as you would any new applicant before agreeing.
What if the remaining tenants cannot afford the full rent alone? That is a real risk once one sharer leaves, because joint and several liability means the departing tenant's share does not disappear from what is owed. Landlords usually need either a quick replacement or a new agreement at a rent the remaining sharers can sustain.
Does joint and several liability apply to the deposit too? Yes. A joint tenancy has one deposit, protected as a single sum even though it may be made up of contributions from each sharer. A deduction caused by one tenant comes out of the shared pot, not just their individual contribution.
