Determining the correct revenue stamp value for loan agreements, especially those exceeding Rs. 100,000, depends on various factors including the loan amount, state regulations, and specific clauses within the agreement. While a Rs. 100 stamp paper might suffice for some cases, stamp duty can vary significantly. It's advisable to consult a local lawyer or your banker for precise guidance, as these fees differ by state and can be influenced by collateral, POA, or hypothecation clauses.
