Three sharers, one joint tenancy. One of them gets a job in another city and sends you two months' notice. The other two want to stay.
Most people, landlords included, assume the leaver simply drops off the agreement. That is not what happens. A notice given by one joint tenant is valid, and it ends the tenancy for all of them.
This is not a technicality anyone invented recently. The Renters' Rights Act 2025 wrote it into statute rather than changing it.
Not legal advice. Joint tenancies are one of the areas where a small misunderstanding produces an expensive outcome. Where the sums or the relationships are difficult, take advice.
What the statute says
Section 20 of the Renters' Rights Act 2025, in force from 1 May 2026, sets the tenant's notice at not less than two months before the date it takes effect. A landlord may agree a shorter period in writing, and that shorter period cannot exceed two months.
Then comes the part that matters here. An agreement for a shorter notice period "is not valid unless it is made between the landlord and all of the tenants". But the restriction is on the agreement, not on the notice: "one or some of the tenants" may still validly give notice to quit.
Read that carefully, because it is asymmetric and the asymmetry is the whole point:
Nobody needs the others' permission to end everybody's tenancy. That is the sentence to absorb.
What it means in practice
When the notice takes effect, the tenancy is over. The remaining sharers are not tenants any more. If they stay in the property with your agreement, they are staying on some new basis, and the question is what that basis is.
The two who wanted to stay have no right to remain under the old agreement, because the old agreement no longer exists. That is uncomfortable to explain and much better explained before it happens.
It also means the deposit position resets. The deposit was taken for a tenancy that has ended, and whatever comes next is a new arrangement with its own protection and prescribed information obligations. Treating a new tenancy as a continuation of the old one is how deposit penalties happen.
The three ways this normally goes
1. A new tenancy with the remaining sharers. The cleanest. The old tenancy ends and you grant a new one to whoever is staying, plus any replacement. Everything starts fresh: references for the new person, a new agreement, deposit protected again with new prescribed information served.
2. A replacement tenant joins. Practically the same as the above. The change of one name is a new tenancy, not an amendment, unless you go down the assignment route, which needs your consent and is worth understanding as its own thing.
3. Nobody stays. The tenancy ends, everyone leaves, you re-let. Simple, and less common than the sharers expect when they first raise it.
What is not on the list is "take the leaver's name off". There is no mechanism for quietly editing a joint tenancy, and a crossed-out name on the original agreement is not one.
Before you agree anything
The single most useful thing you can do is earlier than any of this: say in plain words, at the start of a sharer tenancy, that a notice from any one of them ends it for everyone. Sharers who know that tend to talk to each other first.
Doing the changeover without losing the thread
A sharer changeover touches almost everything at once: a new applicant to reference, a new agreement to sign, a deposit to deal with, a check-in for the room, and a rent schedule that has to keep running through it.
That is the sequence LetCompliance is built around. The applicant comes in through the same link as any other, referencing runs, the new agreement is generated and e-signed, the deposit and its dates are recorded, and the rent ledger continues without a gap. HMO room-level tracking means the rent for the room that changed hands is visible separately rather than folded into one figure for the property.
Common questions
Can one joint tenant end the tenancy for everyone? Yes. Section 20 of the Renters' Rights Act 2025 confirms that "one or some of the tenants" may validly give notice to quit. When it takes effect the tenancy ends for all of them, including any who wanted to stay.
How much notice must a joint tenant give? Not less than two months before the date the notice takes effect. A shorter period can be agreed with the landlord in writing, up to a maximum of two months, but that agreement is only valid if it is made between the landlord and all of the tenants.
Can I just remove the leaver's name from the agreement? No. There is no mechanism to amend a joint tenancy by removing a party. The practical routes are a new tenancy with those who remain, or an assignment with your consent.
Do the remaining sharers have a right to stay? Not under the old tenancy, because it has ended. Anything that follows is a new arrangement that you and they agree, with its own agreement, deposit protection and prescribed information.
Does the deposit carry over? Only if you deal with it deliberately. The tenancy it was taken for has ended, so a new tenancy needs the deposit protected and prescribed information served for that tenancy. Assuming continuity is a common route to a penalty.
Does the guarantor still cover the new tenancy? Generally no. A guarantee given for one tenancy does not automatically extend to a different one, which is a reason to redo it rather than assume it.

Frequently asked questions
Can one joint tenant end the tenancy for everyone?
Yes. Section 20 of the Renters’ Rights Act 2025, in force from 1 May 2026, confirms that "one or some of the tenants" may validly give notice to quit. When that notice takes effect the tenancy ends for all of the joint tenants, including any who wanted to stay. No permission from the others is required.
How much notice does a joint tenant have to give?
Not less than two months before the date the notice takes effect. A shorter period may be agreed with the landlord in writing and cannot exceed two months, but that agreement "is not valid unless it is made between the landlord and all of the tenants". Shortening the notice needs everyone; giving it does not.
Can I just take the leaver’s name off the tenancy agreement?
No. There is no mechanism to amend a joint tenancy by removing a party, and crossing a name off the original document achieves nothing. The practical routes are ending the tenancy and granting a new one to those who remain, or an assignment with the landlord’s consent.
Do the remaining sharers have a right to stay?
Not under the old tenancy, because it has ended. Anything that follows is a new arrangement, which needs its own agreement, its own deposit protection and prescribed information, and references for any replacement sharer.
Does the deposit carry over to the new tenancy?
Only if it is dealt with deliberately. The tenancy the deposit was taken for has ended, so a new tenancy requires the deposit to be protected and prescribed information served for that tenancy. Assuming continuity is a common route to a penalty.
Does the guarantor still cover the replacement arrangement?
Generally no. A guarantee given for one tenancy does not automatically extend to a different tenancy, so a new agreement usually needs a new guarantee rather than reliance on the old one.
