Stamp duty rates on agreements are fixed by each state under Entry 63 of List II of the Seventh Schedule to the Constitution, so the place of signature decides how the document is stamped. The seven judge bench in In re Interplay between Arbitration Agreements and the Indian Stamp Act (2023) held that an unstamped agreement is inadmissible in evidence but not void, and the defect can be cured on payment of duty and penalty. Stamp before or at signing, since curing later delays any urgent application.
Maharashtra applies the Maharashtra Stamp Act 1958, and agreements signed in Mumbai are generally stamped under Article 5 of Schedule I, with duty paid online through the GRAS system. The Mumbai Centre for International Arbitration is a frequent choice for ventures with a foreign partner. The Bombay High Court in Messer Holdings v Shyam Madanmohan Ruia (2010) upheld consensual transfer restrictions between shareholders, and that reasoning now sits in the proviso to Section 58(2) of the Companies Act 2013.
Karnataka stamps under the Karnataka Stamp Act 1957, with e-stamp certificates issued through authorised centres. In Bengaluru's technology ventures, the IP licence and assignment schedules carry extra weight. Code and designs created inside the venture should be assigned by a separate signed instrument, since Section 19 of the Copyright Act 1957 requires assignments to be in writing.
Delhi follows the Indian Stamp Act 1899 as applied to the National Capital Territory, with e-stamping handled by the Stock Holding Corporation of India. The Delhi High Court is a frequent forum for interim relief under Section 9 of the Arbitration and Conciliation Act 1996.
Gujarat applies the Gujarat Stamp Act 1958 and hosts the GIFT City International Financial Services Centre, regulated under the International Financial Services Centres Authority Act 2019. Financial institutions set up in the IFSC and recognised by the regulator are treated as persons resident outside India under the FEMA (IFSC) Regulations 2015, so a stake held through such an entity counts as foreign investment for NDI Rules purposes.
