A guarantee is not the same as a suretyship. Suretyship is an
undertaking that the debtor (tenant) will pay and that only if the debtor
(tenant) does not pay, the surety will do so. Guarantee is an undertaking that
the guarantor will pay if the debtor (tenant) does not pay.
Suretyship is an accessory obligation while a guarantee is a principal
obligation.
The guarantor is the party that provides the guarantee.
