Escalation clause with regard to Security Deposit Contract

Hi,

How to check if any option is there for having escalation clause with regard to Security Deposits contract?

As you know, the periodic posting for security deposit contract happens only once. Suppose, when rent amount( Rs.10,000) gets increased @ 10%(i.e., Rs. 11,000) in next year then, how to handle this kind of situation??

Regards,

Shankar
