In the scenario described, the Demand Draft would be subject to the conditions outlined, but there are potential points where the arrangement could be bypassed. One potential loophole to consider is the nature of joint custody. While you mentioned each party possessing two digits for authentication, the implementation of this system might be susceptible to manipulation or compromise.

Another possible avenue for bypassing the conditions could involve exploiting the timing and execution of the RTGS transaction. If the transaction is not closely monitored or verified, it might be possible to manipulate the transfer process itself, rendering the conditions related to the Demand Draft void.

Solution

Third-Party Oversight:

Independent Auditor: Employ a trusted third-party auditor who regularly reviews and verifies the transactions and custody conditions, providing an extra layer of oversight.
