In our department i.e. RVPNL we take surety bond from the newly appointed Junior Engineers with the condition that if they left the job before lapse of three years they will have to deposit Rs. 1,50,000/-. In the instant case we have obtained surety bond on a non-judicial stamp of Rs. 100/- from the employee and he left the job. Now it came to our notice that the surety bond which has been obtained from the employee, the stamp was not purchased from the name of surety holder. Now how we can recover the amount of Rs. 1,50,000/- ? Please give specific answer at the earliest possible.
