The plaintiff sued the defendant for $258,230.57 as surety and co-principal debtor for Zimbabwe Express Pvt Ltd's rental obligations. The defendant signed a deed of suretyship on 20 September 2004 when CB Richard Ellis were the property agents. A lease agreement was entered into at that time between the creditor and the debtor company. Subsequently, when property management changed from CB Richard Ellis to Knight Frank, a new lease agreement was entered into between the creditor and debtor, but no new suretyship deed was signed with the defendant. The new lease agreement had different terms and conditions from the original one and contained a clause requiring that a suretyship agreement be signed simultaneously with the lease agreement, which did not occur. The plaintiff sought to enforce the original 2004 suretyship deed against the defendant for debts arising under the new lease agreement.
