As per Sec, 52 B of The Bombay Stamp Act 1958 “not withstanding anything contained in Sec 47, 50, 51 and 52 under the relevant provision of this Act; and any stamps not so used or so delivered within the period aforesaid shall be rendered invalid.
The said provision is contrary to the judgment passed by the Hon’ble Supreme Court in W.Petiton No. (civil) 290 of 2001 between Thiruvengada Pillai vs Navaneethammal & Anr passed on 19 February, 2008 by the bench Bench: R V Raveendran, P.Sathasivam.
The Hon’ble Supreme Court said that , “The Indian Stamp Act, 1899 nowhere prescribes any expiry date for use of a stamp paper. Section 54 merely provides that a person possessing a stamp paper for which he has no immediate use (which is not spoiled or rendered unfit or useless), can seek refund of the value thereof by surrendering such stamp paper to the Collector provided it was purchased within the period of six months next preceding the date on which it was so surrendered. The stipulation of the period of six months prescribed in section 54 is only for the purpose of seeking refund of the value of the unused stamp paper, and not for use of the stamp paper. Section 54 does not require the person who has purchased a stamp paper, to use it within six months. Therefore, there is no impediment for a stamp paper purchased more than six months prior to the proposed date of execution, being used for a document.”
Hope your have understood the situation. The situation in other states I am not aware. Please check for the same.
