I’d like to change from sole to joint tenancy.

You can apply to add someone else as a joint tenant by completing the joint tenancy application form here . The person you want to add as a tenant must be either your spouse, partner or relative. Once we’ve received your application your community housing officer will consider your request and contact you with a decision as soon as possible.  If your application is successful, your housing officer will arrange for you and your joint tenant to sign a new tenancy agreement.
