Other adults living with you
If you have any adults living with you other than your partner in most cases it will affect the amount of Housing Benefit and or Council Tax Benefit you receive.
In most cases other adults will be treated as non-dependants, however if they are not related to you and you rent out your property on a commercial basis they may be treated as either ‘lodgers’ or 'sub-tenants' or joint tenants.
