Gujarat Stamp Act, 1958
Every instrument for which sheet of paper stamped with impressed stamp is used shall be written in such manner that the writing may appear on the face and, if required, on the reverse of such sheet so that it cannot be used for or applied to any other instrument. Explanation I.—Where two or more sheets of papers stamped with impressed stamps are used to make up the amount of duty chargeable in respect of any instrument, either a portion of such instrument shall be written on each sheet used, or the sheet on which no such portion is written shall be signed by the executant or one of the executants, with an endorsement indicating that the additional sheet is attached to the sheet on which the instrument is written. Explanation II.—Where the sheet or sheets bearing impressed stamps is or are insufficient to admit of the entire instrument being written thereon, so much plain paper may be subjoined thereto as may be necessary for completing the writing of such instrument, provided a substantial part of the instrument is written on the sheet which bears the stamp before any part is written on the plain paper so subjoined and such plain paper may or may not be signed by the executant but where it is not so signed it shall not render the instrument not duly stamped.
