Section 18. Instruments other than bills and notes executed out of State

(1) Every instrument chargeable with duty executed out of the State and not being a bill of exchange, or promissory note, may be stamped within three months after it has been first received in the State. (2) Where any such instrument cannot, with reference to the description of stamp prescribed therefore, be duly stamped by a private person, it may be taken within the said period of three months to the Collector, who shall stamp the same, in such manner as the State Government may by rule prescribe, with a stamp of such value as the person so taking such instrument may require and pay for.
