What To Do If a Housemate Breaks the Lease in Northern Ireland

Living with housemates in Northern Ireland can be rewarding, but things can get complicated if someone decides to break the lease. Whether you're in a shared house, HMO (House in Multiple Occupation), or have a lodger arrangement, understanding your rights and the process can help protect you and avoid potential disputes.

Understanding Shared Tenancy Agreements in Northern Ireland

Your responsibilities and risks depend on the type of tenancy agreement you and your housemates have:

• Joint tenancy: Everyone signs the same tenancy agreement. All housemates are collectively responsible for the rent and any damages.
• Individual tenancy: Each housemate has a separate agreement with the landlord, just for their room or space.
• Lodger arrangements: If you are renting a room in your landlord’s home, you are likely a lodger – different rules apply than standard tenancies.

In Northern Ireland, most private tenancies (including HMOs) fall under the Private Tenancies (Northern Ireland) Order 2006^[1].

If a Housemate Wants to Leave Early

If a housemate wants to move out before the fixed term ends:

• They generally need the landlord’s (and sometimes other tenants’) agreement.
• Simply telling you or moving out does not end their obligations – they remain liable for rent and responsibilities until the agreement ends or is changed.

If you are on a joint tenancy, this can affect all housemates. You could be left covering the departing tenant’s share of the rent unless a replacement is found or the agreement is changed.

What Happens to Rent and Deposit?

• Joint tenancy: The remaining tenants are collectively responsible for the full rent. If one person leaves, the landlord can chase any or all tenants for unpaid rent.
• Individual agreements: The other tenants are usually not affected financially, but consult your tenancy agreement to be sure.
• Lodgers: Notice periods are typically shorter and arrangements more flexible, but check your written agreement for terms.

Changing or Ending the Agreement

The landlord may agree to end the current joint agreement and start a new one with the remaining tenants and/or a replacement. This is usually called a "surrender" or "deed of surrender." Always get any changes in writing.

If a new tenant is found, they must complete reference checks and may need to sign a new agreement. Deposits must usually be updated accordingly with one of the government-approved schemes. In Northern Ireland, this is managed through the Tenancy Deposit Schemes^[2].

What if the Housemate Just Leaves?

If your housemate leaves without notice or without ending the agreement properly:

• You may need to cover their share of rent, especially in a joint tenancy.
• Inform your landlord as soon as possible and seek advice from official services.
• If you're concerned, contact the Housing Rights Service for confidential support.

How to Formally End the Tenancy (Forms and Tribunals)

If the whole tenancy needs to end, your landlord must serve written notice using the official form.

• Notice to Quit (Form NTQ): This is used when the landlord or tenant wishes to end the tenancy. The notice period varies by tenancy length (usually 4 weeks minimum for less than 10 years, 12 weeks for more than 10 years).
• You can read more and find this form on the NI Direct Notice to Quit Guidance.

If there’s a dispute (for example, about unpaid rent or deposit deductions), you might need to take the issue to the tribunal for decision:

• Residential tenancies tribunal in Northern Ireland: The Residential Tenancies Tribunal handles disputes between landlords and tenants, including those arising from shared tenancies or HMOs.

Action Steps If a Housemate Breaks the Lease

• Speak with your landlord and housemates as soon as possible.
• Check your tenancy agreement for specific rules.
• If struggling with rent or negotiations, seek advice from Housing Rights.
• Keep written records of all communication.

FAQs: Shared Housing When a Housemate Leaves

1. Can a landlord evict remaining tenants if one housemate leaves?
   In joint tenancies, your landlord may seek to end the agreement if there’s unpaid rent. In individual agreements, your rights are less likely to be affected. In either case, correct notice must be served.
2. Am I legally required to pay my housemate’s share if they abandon the tenancy?
   For joint tenancies, yes – all tenants are jointly responsible for the rent. For individual tenancies, you are only responsible for your portion.
3. Can I replace my housemate myself?
   You often can, but must get your landlord’s written permission and ensure the new housemate completes reference checks. Any new agreement should be documented in writing.
4. How do I challenge unfair deposit deductions when a housemate leaves?
   Contact the tenancy deposit scheme protecting your deposit. If the dispute is not resolved, you can apply to the Residential Tenancies Tribunal for an official ruling.
5. Where can I get official forms or legal advice?
   Official forms, including the Notice to Quit, are available through NI Direct and advice from Housing Rights.

Key Takeaways for Renters
