When taking a non-collateral loan from an NBFC, it's common for them to request blank cheques as security. While this is a standard practice for lenders to protect their investment, it's crucial to ensure your own security. It's advisable to have the details of these cheques, including their purpose and the fact that they are for security only, clearly documented in the loan agreement. This provides a safeguard against potential misuse and clarifies your liability. Always ensure you retrieve these cheques upon loan closure or cancel them.
