A joint tenancy is where two people share equal responsibility for paying the rent and the other responsibilities of the tenancy agreement.
If you just need a friend or relative to be able to contact us on your behalf, for example to report repairs, you don’t need to add them as a joint tenant. You can give them authority to act on your behalf.
Adding or removing a joint tenant
Normally you can only become a joint tenant if you're married to or in a long-term partnership with the current tenant. Children can’t usually become joint tenants.
