You share a house with two friends, and one of them has landed a job in another city. They want to give notice and move on. Fair enough. What none of you realised is that their notice may end the tenancy for all three of you, whether the rest of you wanted to stay or not.
This is one of the quieter traps in how joint tenancies work, and the move to periodic tenancies has made it more common. Worth understanding before anyone in your house share reaches for a notice.
Can one person leave a joint tenancy without ending it for everyone?
Usually not, and this is the part that catches people out. On a joint periodic tenancy, a notice to quit from one joint tenant ends the tenancy for everyone on the agreement. The others do not get a say, and the landlord does not need to agree.
This comes from a long-settled rule in Hammersmith and Fulham LBC v Monk [1992] 1 AC 478. A periodic tenancy carries on from one period to the next only if all the joint tenants agree to it continuing. When one serves notice, that shared agreement is gone, so the whole tenancy ends. The Renters' Rights Act made the tenancy periodic for almost every private renter in England, meaning anyone renting from a landlord they do not live with, so the rule now reaches far more house shares than it used to.
Put plainly, a leaving housemate does more than give up their own share. Their notice pulls the whole tenancy down with it.
How much notice does a joint tenant have to give under the Renters' Rights Act?
Since 1 May 2026, a tenant ends a periodic assured tenancy by giving the landlord two months' notice to quit, a period set by the Renters' Rights Act 2025. Two months is the default and the longest a landlord can insist on. A shorter period is possible, but on a joint tenancy it only counts if the landlord and all of the joint tenants agree it in writing. One housemate cannot privately arrange a quicker exit.
Timing matters too. The notice has to expire at the end of a rent period, not on any date two months away. If your rent runs from the 5th of the month, a notice cannot end on a random Tuesday. Get that wrong and the notice can be invalid, so check the dates carefully. We walk through serving a valid notice in how to end your tenancy with a notice to quit in 2026.
What happens to the housemates who want to stay?
Once one joint tenant's notice takes effect, the tenancy ends for all of you. The housemates who wanted to stay have no automatic right to remain. In law, they become people living in a property with no tenancy, and the landlord could ask them to leave.
In practice a landlord happy with the remaining tenants will usually want to keep them, because an occupied property earns rent. But staying rests on agreeing a new tenancy, not on the old one. So treat a housemate's decision to leave as a conversation to have early, and line the landlord up before the notice ever lands.
How to get a new tenancy for the people staying on
The safe route for the housemates staying is a new tenancy in their names, agreed with the landlord. It replaces the joint tenancy the notice ended, and it is the task worth putting first.
Get the new agreement in writing before the leaving tenant's notice expires, so there is no gap where nobody holds a tenancy. If you need someone to cover the departing housemate's share of the rent, raise a replacement early, because the landlord will usually want to reference them the same as at the start of a let.
This is an arrangement to negotiate, not a right you can demand. The landlord does not have to offer a new tenancy, and can set its terms, including the rent.
What happens to the deposit and a leaving tenant's guarantor?
A joint tenancy usually has one deposit, protected as a single sum for all the tenants together. It is not split and handed back when one person leaves. What matters more is what the changeover does to the protection.
The new tenancy is granted to a different set of tenants, so it does not count as a replacement tenancy under section 215B of the Housing Act 2004, which only carries protection across where the landlord and the tenants stay the same. That means your landlord has to protect the deposit again, and serve the prescribed information again, within 30 days of the new tenancy starting, even where the same money never leaves the scheme. If they miss that, the tenants on the new agreement can claim 1 to 3 times the deposit under section 214. So check the protection in the new tenants' names once the changeover is done, using how to check if your deposit is protected and, for the day you all move out, what counts as a fair deposit deduction.
A guarantor's liability follows the tenancy they signed up to, and on a joint tenancy that usually meant the whole rent, across every tenant. When that tenancy ends and a new one starts, the cover does not automatically carry across, so the landlord may want a fresh guarantee. What the guarantee document says decides it, and we cover that in when a guarantor can and can't be chased.
What to do before you or a housemate serves notice
Start by checking who is named on the tenancy. The rule only bites on genuine joint tenants sharing one agreement, so if each of you signed a separate tenancy for your own room, one person leaving ends only their own. If you are joint tenants, agree the plan as a household before anyone serves anything. Handled in the wrong order, one person's move can cost everyone their home. Handled in the right order, it is a manageable reshuffle.
If your housemate is about to give notice and you want to stay, Remedy can check your tenancy, explain what the notice does to the rest of you, and help you line up the new agreement with the landlord.
