Sharing a tenancy: what joint and several liability means

Both approaches to shared tenancies work. What differs is what they cost you, and the cost is what this sets out.

Two very different structures

A joint tenancy is one agreement signed by everyone, covering the whole property, with one rent and one deposit. Individual room agreements make each tenant liable only for their own room and rent, with the landlord carrying the void risk.

The first is cheaper for landlords and riskier for tenants; the second is the reverse. Which one you have is written on the agreement, and many sharers do not know which they signed.

What joint and several actually means

If one housemate leaves without paying, the landlord can pursue any of the others for the entire shortfall. The tenant who pays can in principle recover from the one who did not, which is a separate and often unrewarding exercise.

On an ordinary week, the same applies to damage anywhere in the property, including rooms you never entered. This is why choosing housemates is a financial decision as well as a social one.

Changing a housemate mid-tenancy

Replacing a leaving tenant usually requires the landlord to agree and, depending on the system, a deed of assignment or a new tenancy. A new tenancy can reset the fixed term for everyone, which the remaining sharers may not want.

Agents often charge for the change where permitted, and several jurisdictions now cap or ban such fees. Agreeing the process in advance, in writing between sharers, prevents the argument arriving alongside the departure.

The deposit is one deposit

A single protected deposit is returned as a single sum, usually to a nominated lead tenant, and dividing it is the tenants problem. A departing sharer who wants their money before the tenancy ends is asking the others to fund it, which needs an agreement. Deductions at the end are taken from the whole deposit regardless of who caused them.

Photographing your own room and the common areas at check-in protects you against being charged for someone else.

Bills and the informal economy of a share

Utility accounts in one name make that person liable for the whole bill, which is the same trap as the rent in miniature. A written record of who pays what, and a shared account or app, prevents the slow accumulation of resentment that ends shares.

Where a bills-included rent is offered, check whether there is a usage cap and what happens if it is exceeded. Council or municipal taxes on shared houses are treated differently in different places, including exemptions for students.

Some of this will suit you and some will not, and that is the point.

Houses in multiple occupation

Many jurisdictions regulate shared houses above a size, requiring licensing, fire safety measures and minimum room dimensions. Where licensing applies and is absent, tenants sometimes have remedies including rent repayment.

Checking whether the property should be licensed, and whether it is, takes one enquiry to the local authority. A landlord unwilling to answer that question has answered it.

Side by side

The takeaway

Find out whether you signed one agreement or several. Everything else follows from that.

Pick the one that costs you least, and let the rest wait.
