If you are the student who will be living with us you are the tenant. Your guarantor is a person over the age of 25 that agrees to be responsible for paying any amount you owe to Unite Students in the event that you (the tenant) do not. Your guarantor will be listed in the tenancy agreement and also has to accept their own agreement. If incorrect guarantor information is provided, it could become a legal matter and mean that your contract is not valid.
