Maharashtra applies the Maharashtra Stamp Act 1958 rather than the central Act, and lenders in Mumbai or Pune usually buy an e-stamp certificate before signing. Anyone who advances money at interest to several people should check the Maharashtra Money-Lending (Regulation) Act 2014, which requires a licence for those carrying on the business of money-lending. A single loan to a cousin does not make you a money-lender, but a regular pattern of interest-bearing loans can. A written personal loan agreement supports summary suits under Order XXXVII of the Code of Civil Procedure before the courts to which it applies, which makes a properly stamped agreement a real asset in recovery.
Karnataka stamps loan agreements under the Karnataka Stamp Act 1957 and regulates lenders through the Karnataka Money Lenders Act 1961. The State also enacted the Karnataka Prohibition of Charging Exorbitant Interest Act 2004, under which charging interest above the notified ceiling is an offence. A friend lending at a bank-linked rate is rarely affected, yet informal daily or weekly interest arrangements expose the lender to criminal complaints. Bengaluru parties increasingly sign by Aadhaar eSign, which is valid for a loan agreement, provided stamp duty is paid separately through e-stamping.
Tamil Nadu runs the strictest regime. The Tamil Nadu Prohibition of Charging Exorbitant Interest Act 2003 makes it an offence to collect interest above the rates fixed under State law, and the police act on complaints under it more readily than most lenders assume. The Act reaches private individuals as well as professional financiers, alongside the licensing rules of the Tamil Nadu Money-Lenders Act 1957. Any interest clause for a Chennai or Coimbatore borrower should therefore stay moderate and be stated as a plain annual percentage.
Delhi uses the Indian Stamp Act 1899 as applied to the National Capital Territory, with e-stamp paper issued through authorised centres. Money-lending is governed by the Punjab Registration of Money-lenders Act 1938 as extended to Delhi, which bars recovery suits by unregistered money-lenders; an isolated personal loan between friends falls outside it. A clean personal loan agreement paired with bank records shortens proceedings in Delhi's crowded district courts.
