<h1>Supreme Court Confirms Stamp Papers Never Expire; Six-Month Rule Only for Refunds u/s 54 of Indian Stamp Act.</h1> Stamp papers remain valid indefinitely and do not expire after six months of purchase, as clarified by a Supreme Court judgment in the case of Thiruvengada Pillai vs. Navaneethammal and Anr. The Indian Stamp Act, 1899, does not specify an expiration date for stamp papers. Section 54 of the Act allows for a refund of the stamp paper's value if surrendered within six months of purchase, but this timeframe pertains only to refunds, not the use of the stamp paper itself. Thus, there is no requirement to use a stamp paper within six months of its purchase.
