(1) Except as otherwise expressly provided in this Act, all duties with which any instruments are chargeable shall be paid, and such payment shall be indicated on such instruments, by means of stamps—
(a) according to the provisions herein contained; or
(b) when no such provision is applicable thereto—as the State Government may by rule direct.
(2) The rules made under sub-section (1) may, among other matters, regulate,—
(a) in the case of each kind of instrument—the description of stamps which may be used;
(b) in the case of instruments stamped with impressed stamps—the number of stamps which may be used;
(c) in the case of bills of exchange or promissory notes—the size of the paper on which they are written.
Legal Commentary & Landmark Judgments: Section 10
Section 10 of the Indian Stamp Act, 1899 prescribes the mandatory statutory forms and mechanisms for payment of stamp duties, directing whether payment must be evidenced by impressed stamps, adhesive stamps, or modern electronic stamping certificates as regulated by statutory rules.
Verify state-specific Stamp Rules before executing high-value commercial contracts: check whether franking, e-stamping, or physical stamp paper is mandatory. Using an unnotified mode of payment (such as a plain treasury challan without an impressed certificate) results in the document being deemed unstamped under Section 15, exposing it to Section 33 impounding.
