Adding a Person to Your Tenancy Agreement in Northern Ireland

Thinking about sharing your rented home in Northern Ireland? Adding someone to your tenancy agreement isn’t always straightforward, but there are clear steps you can follow. This article explains everything you need to know about the process, including which official forms to use, how to get your landlord’s agreement, and your rights under Northern Ireland’s tenancy laws.

Understanding Tenancy Types in Northern Ireland

Tenancy agreements in Northern Ireland are governed by the Private Tenancies (Northern Ireland) Order 2006. Most renters have an Assured or Regulated tenancy, but adding someone to your agreement usually requires landlord approval regardless of tenancy type.

  • Sole Tenancy: Only one person is legally responsible for the rent and obligations.
  • Joint Tenancy: Two or more people share equal responsibility for the property.

If you want to add someone (for example, a partner or friend) officially, you’ll need to request that your landlord updates the tenancy to a joint tenancy.

First Steps: Talk to Your Landlord

Additions to a tenancy are at the landlord's discretion. Start by contacting your landlord or letting agent. Clearly explain who you want to add and why. Most landlords will want to perform reference checks and may ask for identification from the new tenant.

Agreement to Vary the Tenancy

If your landlord agrees, you’ll need a variation of tenancy. This is usually done by drafting a new contract or signing a written agreement (sometimes called a "deed of variation") that names all new and existing tenants. This makes both parties (you and the person being added) liable for rent and all tenancy obligations.

  • There is no specific government form for adding someone to a private tenancy in Northern Ireland. The variation should be in writing and signed by all parties.
  • You can find general guidance on secure variations from the NI Direct: Types of Tenancy Agreement page.

Example Process

  • Step 1: Get written permission from your landlord to add the new person.
  • Step 2: Draft a new tenancy agreement or an addendum that includes both (or all) tenants.
  • Step 3: Ensure every tenant and the landlord signs the updated agreement.

Once complete, each tenant is equally responsible for fulfilling the tenancy conditions, including paying rent and caring for the property.

If you’re unsure about the process, reach out to the Housing Rights Service or your local council for advice before signing anything new.

What About Social Housing?

If you’re renting from the Northern Ireland Housing Executive (NIHE) or a housing association, there are specific processes and forms to follow. The NIHE uses the Joint Tenancy Request process. Social tenants can get more information on their joint tenancies guidance page, or by contacting their local housing office.

  • NIHE Joint Tenancy Application Form
    • When to Use: If you want someone to have equal rights and responsibilities in your social tenancy, use this form to apply for a joint tenancy.
    • Find It: Request the form from your local NIHE office or visit the NIHE joint tenancy guide.

Private renters should note there is no formal application form—the process as outlined above applies.

Key Considerations Before You Add Someone

  • Once added as a joint tenant, both parties have equal legal rights and responsibilities for the property.
  • If a joint tenant leaves, the remaining tenant may have to pay the full rent or negotiate a new agreement.
  • Changes to housing benefit or Universal Credit tend to occur when joint tenancies are established; always notify the appropriate benefits offices.
  • If the landlord refuses your request, they must treat everyone fairly and comply with the Equality Act 2010.
Keep a copy of any new tenancy agreement or written variation. This is your proof of rights and responsibilities as a joint tenant.

If There’s a Dispute or Refusal

Should you face problems—such as an unreasonable refusal or a disagreement around responsibilities—you can seek help from the Private Rented Housing Panel. This is Northern Ireland’s main tribunal for resolving private tenancy disputes. More background and contact information are available on the official justice portal.

  1. Can my landlord refuse to add someone to my tenancy?
    Yes, in most cases, a landlord can refuse unless the original tenancy agreement allows tenants to add others without permission. Always check your agreement and discuss with your landlord first.
  2. Do I need a new tenancy agreement?
    Usually, yes. Adding someone typically means replacing your current agreement with a new joint tenancy, or you both sign an official variation document.
  3. Is there an official form to add someone to a private tenancy?
    No formal government form exists for private tenancies. The change should be put in writing and signed by all parties. Social tenants (such as NIHE tenants) use the NIHE Joint Tenancy Application Form.
  4. What rights does the new joint tenant have?
    Both tenants have equal rights and responsibilities—including paying rent, staying in the property, and ending the tenancy.
  5. Whom can I contact if there’s a disagreement?
    If you can't resolve it with your landlord, contact the Private Rented Housing Panel in Northern Ireland for independent dispute resolution.
