Shared Housing Lease Guide for Tenants

TL;DR: In a joint tenancy, every housemate is equally responsible for the full rent — not just their share. Understanding your legal structure before signing is the single most important step in shared housing.

Shared housing is common among students, young professionals, and anyone looking to reduce costs in expensive cities. But sharing a home means sharing legal obligations — sometimes in ways that can seriously affect your finances if a housemate stops paying rent, causes damage, or leaves unexpectedly.

This guide explains how shared housing leases work in the UK, France, Sweden, Australia, New Zealand, Canada, and the USA.

What You Need to Know

Shared housing typically takes one of two legal forms:

Joint Tenancy

All tenants sign a single lease together. Key features:

• Joint and several liability: Each tenant is responsible for the full rent — not just their share. If your housemate doesn't pay, the landlord can pursue any one of you for the entire amount.
• All must agree: Any change to the tenancy (ending it, adding a tenant) requires all parties' consent.
• One deposit: Usually, a single deposit is held — disputes over its division are between the tenants.

Individual Tenancies (Room-by-Room)

Each tenant signs a separate lease for their own room. Key features:

• Separate liability: You are responsible only for your own rent.
• Easier exits: You can end your tenancy without affecting housemates.
• Separate deposits: Each tenant has their own deposit.

Most landlords offering shared housing prefer joint tenancies because they are easier to enforce. Many students, in particular, find themselves in joint tenancies without fully understanding the implications.

Before You Sign: Key Questions

1. Who Is on the Lease?

Confirm that all housemates are named on the lease. In a joint tenancy, any housemate not on the lease is technically a guest — they have no legal right to the property but also bear no legal obligation to the landlord.

2. What Happens If Someone Leaves?

In a joint tenancy:

• All tenants must agree to end the tenancy
• The departing tenant cannot unilaterally leave without the others' agreement
• A new joint tenancy may need to be signed if someone is replaced

In an individual tenancy:

• The departing tenant can give notice independently
• The landlord decides whether to accept a new tenant

France (bail solidaire): The solidary clause means each co-tenant can be pursued for the full rent, even after they have moved out — until a new co-tenant signs and is accepted by the landlord.

3. How Is the Deposit Split?

Agree in writing before moving in:

• What percentage of the deposit each person contributes
• Who is named on the deposit protection certificate (UK)
• How disputes over deductions will be resolved between housemates

4. How Are Bills Divided?

Bills are not part of the tenancy agreement — they are a private arrangement between housemates. Common arrangements:

• One person's name on all utilities; others pay their share
• Bills split proportionally by room size
• Joint account specifically for shared bills

The tenancy agreement is silent on bills. Disputes about bills cannot be taken to a tenancy tribunal — they are private debts between housemates.

When a Housemate Stops Paying

This is the most common shared housing crisis. In a joint tenancy:

1. You are liable for their share: The landlord can demand the full rent from you (or any other co-tenant) if one person stops paying.
2. Pursue the non-paying housemate separately: You can seek to recover their share through small claims court or a debt recovery process — but this is your action, not the landlord's.
3. Negotiate with the landlord: Explain the situation early. Some landlords will accept part-payment temporarily while you resolve the situation — but they are not obliged to.
4. Consider a guarantor: If you are signing a joint tenancy and one housemate has a weaker financial background, request that they provide a personal guarantor.

Adding or Replacing Housemates

UK

In a joint tenancy, all existing joint tenants must agree to any change. If one tenant leaves, the landlord may:

• Grant a new tenancy to the remaining tenants plus the new person
• Refuse and require everyone to vacate

There is no automatic right to replace a departing joint tenant.

France

Under a bail solidaire, a new co-tenant can replace a departing one if the landlord agrees. The departing co-tenant remains jointly liable until a new signed agreement is in place.

Australia and New Zealand

Assignment of a co-tenant's interest requires landlord consent. A new joint tenancy is often the cleanest approach.

House Rules and Housemate Agreements

While not legally binding in most jurisdictions, a written housemate agreement can prevent disputes. Consider covering:

• Rent and bills: Who pays what, when, and how
• Cleaning responsibilities: Shared areas, frequency, standards
• Guests and partners: How long guests can stay
• Quiet hours: Particularly important if housemates have different schedules
• Food: Shared or separate; labelling rules
• Moving out: Expected notice to housemates, not just to the landlord

Common Mistakes to Avoid

1. Not reading whether it's a joint or individual tenancy — the difference in liability is enormous
2. Assuming you can leave whenever you want — in a joint tenancy, leaving without agreement may breach the lease and leave you liable for rent until someone replaces you
3. Not agreeing deposit splits in writing — verbal agreements are almost impossible to enforce when deposits are disputed
4. Paying bills in one person's name without a written arrangement — when they leave, utilities follow them unless agreements are in place
5. Not vetting housemates carefully — in a joint tenancy, their credit and reliability affect you directly

Frequently Asked Questions

Q: If one housemate's name is not on the lease, what rights do they have?

A: Very few formal rights under tenancy law. They may be considered a subtenant of the named tenants rather than a direct tenant of the landlord. If the lease ends or the named tenants leave, the unnamed occupant may have no legal protection against eviction. Always ensure everyone who lives in the property is named on the lease or has a separate agreement.

Q: Can I remove a housemate from a joint tenancy?

A: Not unilaterally in most jurisdictions. You would need the cooperation of all joint tenants and the landlord to change the tenancy agreement. If a housemate is causing serious problems (non-payment, antisocial behaviour), seek advice from a tenant advocate before taking action.

Q: What happens if a joint tenant dies?

A: Under the legal principle of "survivorship," in a joint tenancy, the deceased tenant's interest typically passes to the surviving joint tenants (in common law jurisdictions). The lease usually continues with the remaining tenants. The landlord should be notified promptly.
